    We are proud to introduce the latest in our line of N54 turbocharger products the VTT Stage 2+ hybrid turbochargers. We take our already robust stage 2 design, and add the highest flowing wheels in the TD04 family to provide the ultimate in N54 stock frame power potential. There is not another stock frame turbo option on the market that can match the power or reliability of our stage 2 turbos. How can we claim this? Lets break down what has become standard in our stage 2 turbos that a lot of people have overlooked. 1. We are the only N54 stock frame turbo manufacture offering billet wheel choices from 14T all the way up to our newest editions which use the massive 20T wheel 2. Our 9 blade Garrett turbine wheel. This is not a MHI 12 blade wheel thrown into CAD and had 3 blades knocked off it ala the Kamak or Kinugawa 9 blade TDD4 turbines you will find out there being used in other applications. This is THE Garrett GT series turbine used in all the fastest spooling and highest flowing Garrett GT and GTX turbochargers. What we did was simply take the Garrett design and have it shrunk into TD04L dimensions, offering the highest flow, fastest spool, and best aero of any TD04 turbine wheel on the market. Keep in mind we have been using this design since 2012 on all our stage 2's we are not now just jumping on the 9 blade band wagon. 3. To combat the inherent oiling issues these stock frame turbos have been faced with, we went back to the drawing board and after numerous changes we now offer DUAL piston rings in all our of stage 2 turbine wheels, this is similar technology you will see in such turbos are Borg Warner EFR, etc. This extra piston ring provides another barrier to keep exhaust out during those high Back pressure pulls, and in turn keep that oil in, helping improve life even under extreme conditions 4. As you already know each and every stage 2 turbocharger comes with an upgraded TD04 thrust and thrust parts to provide extra oiling and surface area to provide longer life, as the thrust take 90% of the abuse inside a turbocharger 5. The biggest compressor wheel options the TD04 family has to offer, all while retaining your stock bolt in fitment, simply unbolt your stockers or other hybrid turbos, and bolt these in, no modifications required Pricing is as follows: Stage 2+ with Billet 19T Compressor Wheel option $3599 - WHP potential 590-615WHP* Stage 2+ with Billet 20T Compressor Wheel option $3699 - WHP potential 600-650WHP* 15 degree clip to 9 blade turbine option $300 (this is for people looking for maximum flow and power, will result in slightly slower spool) Core charge still applies: $300 for 335LHD, $600 for all other models We are considering a group buy in the next few days offering a group buy discount if interest is high enough Also YES there will be a trade in for people who already have our stage 2 turbos or RB's, drop us an email for details! Estimated shipping on these is 30-60 days *Please note all power figures are estimated AND done so with PROPER complimenting upgrades, tuning, and FUEL. Running these turbos on pump gas only will net you a little more power over a standard Stage 2 set up, but not much. You need octane to bring the true potential from these turbos All the testing you see below was done using: Turbos: VTT Stage 2+ with Clipped turbines, and Billet 20T compressor wheels Fuel: 100% E85 Tuning: Tuned by Dzenno of Protuning Freaks using the Cobb AP FLASH ONLY Final Pull was 27 psi down low tapering to 24.5 psi at redline Please direct any and all questions to: Sales@vargasturbo.com Lets get into the dyno results and logs. We would like to start out by saying, we stopped short on the dyno because we had a fueling issue, as I did not come prepared, we had our Shotgun set to its lowest voltage setting, and as we brought power in the top end up to the 600WHP range we started seeing HPFP drop into a range that while not tanking was lower then we like to see, we will swap into our next higher voltage power module and get the car back on the dyno. This will allow us to run the timing we want, and bring the boost up most likely bringing us right into the 650WHP / 650WTQ range. For our first run, we pulled the car onto the dyno and ran a map we tested the last few times on the dyno that made a consistent 52XWHP / 54XWTQ with modest boost and timing. While trying to watch numerous things during the pull I should have paid more attention to the boost gauge, the car made it clear it was not happy on the top end and I could feel it nosing over. After the run, I pulled up the log and HOLY SH** the car made 40psi to reline, how we didn't blow the motor right there is a testament to the toughness of the N54 and how effective the DME is at protecting the motor when it is seeing all the information. The boost the car made surprised us both and we immediately started pulling WDGC out of it to bring the back down to a reasonable level. None the less we knew we were onto to something good when we saw the first graph. All Logs can be found in the ZIP file attached, lowest number is first pull, highest is last. All Runs done in 4th gear :whiteflag::scared-eek: First Pull Graph With boost lowered we tried another run, boost was still way to high for our liking so we dropped it again. Second pull graph Third, I watched the boost gauge closely and did not like what I saw so I lifted early and me and D both decided it was time to ditch the old maps and start over. Third pull graph At this point Dzenno went in and pulled everything back so we could sneak up up on what we wanted to see. The 4th graph shows we had a decent starting place Forth pull Graph From here it was Dzenno working his magic building a nice smooth boost curve and naturally the power comes with it. Keep in mind we did not touch timing, these numbers are on 10-12 degrees on timing, as we were not happy with the fuel situation. On our last round of 15T testing we were running 15.5 degrees of advance with no issues. Adding that timing back in will net us at least another 20WHP Fifth Pull Graph Sixth Pull Graph Seventh Pull Graph Eighth Pull Graph Ninth Pull Graph Final Pull Graph Final Pull with speed to show forth gear pull Here are some photos of the turbine wheels for reference. Biggest turbine Genuine Garrett GT series 28 turbine wheel, next out Garrett Clone TD04L, next MHI TD04L(RB) Difference in flow is clear. Here are some pics of the turbos as tested just from the compressor side, turbine side looks exactly like a set of normal stage 2's except a clipped turbine. Notice the OLD tags on these housings, we haven't used the red and blue tags since Stage 2 batch 1! That is how long we have had these housings on the shelf, we should have tested these a long time ago...:facepalm First pics are 15T's in 20T housing, next are 20T's.

    Well that was fast, wasn't it? The big news in the N54 scene recently is that the OEM turbocharger stock frames are making some ridiculous power. Just a couple days ago Vargas Turbo Technology officially announced their Stage 2+ hybrid turbochargers and posted a ton of data including a new stock frame world record of 627 wheel horsepower. Well, just a couple days later the record now stands at 645 horsepower (and 654 lb-ft of torque at the wheels was also hit on a run). Depending on how these are tuned for the peak torque and horsepower figures will obviously change but obviously the stock frames are capable of more power and torque than anyone originally thought was possible even including Vargas Turbo Technology themselves. More details below along with the dyno graphs but N54 tuning continues to move forward: Vargas Turbo Tech: 'We then continued our tuning session until it was cut short by Dzennos wife telling him it was time to be done. We threw a 5th gear run in at the end for shits and giggles and made 654WTQ, but less WHP, when you are pushing this power all the way to redline, as you will see the 5th gear pull bumps up power and TQ down low but adds nothing up top. A 5th gear dyno pull is similar to what you will be making on the street with the added load. Either way we fixed the HPFP and our shotgun performs FLAWLESSLY I honestly love that system so much, it just makes fuel, but it seems we have possibly found the flow limit of the injectors as even with PLENTY OF FUEL we sometimes found ourselves lean up top, and with trims maxing, Dzenno richened it up up top and it helped. This log is perfect and was a the 641 / 625 run, our cleanest one, just to be safe when I head to the track we will mix a little 109 and richen the mixture up. To prove the other theories wrong, we maxed the HPFP across the board, it didn't fix the lean condition or trims, if you have plenty of fuel to the injectors and you are running lean, it usually means you are maxing out duty cycle, we will see.'

    Modifying the stock frame BMW N54 turbochargers has received a big boost in popularity recently. This is due to the big numbers Vargas Turbo Technology (and others) have shown the stock frames capable of putting out when properly modified. This created an opportunity for a comparison to some of the latest single turbo N54 turbo setups and the graph below features an overlay between the modified twins and a single turbo. The single turbo kit is from Ventura Motorsports. It is based around a Comp Turbo 6465 turbocharger. Now looking at the graph the single turbo makes more power but interestingly has less torque. The modified stock frame twins spool spooner and you could say hit harder down low while the single turbo offers more top end. Now, these numbers can obviously change drastically based on tuning, fuel, supporting modifications, etc. A pump gas comparison would be interesting to see as high octane fuel is used here. Additionally, keep in mind the single turbo has far more headroom to gain power. Still, this is an interesting overlay to see with the two different approaches compared on a single graph.

    This race is simply a beatdown. To those that know the cars it should not be all that surprising. Both cars feature tunes from PP-Performance. The C63 AMG Black Series M156 engine is already in a high state of tune from the factory. As the 6.2 liter M156 engine is naturally aspirated and tuned aggressively by AMG there is not much room to gain power on the car. Certainly not as much room to gain with a tune as there is with the turbocharged M4. The cars put out very similar wheel horsepower figures in stock form as the C63 AMG Black Series shows ~430 wheel horsepower on a Dynojet. With a tune this can approach the 460 wheel horsepower range depending on how aggressive the timing is and the fuel quality. The stock torque figure is roughly ~405 lb-ft of torque at the wheels whereas the S55 in the M3/M4 shows 429 lb-ft of wheel torque stock. Once tuned, even with a modest tune, the M4 exceeds the C63 Black Series. Horsepower rises to over 479 at the wheels and torque at the wheels goes to 484 lb-ft. Combine the power and torque advantage with a quicker shifting dual clutch transmission and the M4's roughly 400 pound lighter curb weight and you get the result you see here. Not to mention the C63 AMG Black Series aerodynamics also create more drag. The M4 continues to pull impressively to 175 miles per hour and the C63 AMG Black Series is too far back to even be seen. AMG fans will no doubt be quick to point out that if you boost the C63 AMG Black Series things change in the other direction.

    The new F80 M3 and F82 M4 are much more powerful than the outgoing E92 M3. Just take a look at the dyno numbers stock and with a JB4 tune for the F80 M3. The F82 M4 output is in the ~420 wheel horsepower range stock compared to the ~350 wheel horsepower range for the naturally aspirated E92 M3 4.0 liter S65 V8. There also is a large torque disparity as the boosted S55 inline-6 in the F82 M4 shows 429 lb-ft at the wheels compared to 253 lb-ft at the wheels for the S65 V8. It is a big difference in output. However, this E92 M3 is tuned with bolt on modifications. The modifications listed are good for about 380 wheel horsepower. So, it is still at a power disadvantage against a stock M4 let alone a modified M4 that with a BMS JB4 tune can approach the 500 wheel horsepower range. The M4 runs a 12.2 @ 121 in the first pass and a bolt on E92 M3 will simply not match that trap speed. The E92 M3 runs a 12.6 @ 111. Neither of these are quick times but the cars appear to be running in warm summer weather so both have room to improve. It is also important to point out that with a DCT transmission the M4 would likely be a few tenths quicker On the second pass the M4 turns off the JB4 piggyback. The E92 M3 does not use launch control on this pass although it should. Regardless, the E92 gets the better launch and the lead which holds off the M4 until horsepower takes over and the M4 pulls. It closes the gap but not quickly enough running a 13.2 @ 121. Why is the trap speed the same as the JB4 run? Good question. That can be attributed to the poor 2.6X 60 foot as spinning the tires usually inflates trap speeds. The M4 hooked better when running the JB4 and that lowered the trap speed although it produced a second better 1/4 mile time. The E92 M3 wins the second race despite a poor 2.277 60 foot but it is clearly the slower car as evidenced by the trap speed. Both drivers need to practice (and the E92 needs boost) but this is definitely an interesting comparison to see.

    Finally, a real announcement from proTUNING Freaks about the turbo kit and fueling solutions that our own brand MOTIV Motorsport has been working so feverishly on for the last year. In the aftermarket performance world it is often a race to be the first out with a product. While we would like to be able to do that as well as keep focus on our core ideals of quality and race proven power/reliability – we simply could not do so without extensive testing on and off the track. Over the last year we have put over 10,000 miles of daily driven duty as well as multiple practice and national level competition NASA road course events and abuse on the MOTIV Single Turbo Kit. We are not simply a shop that made a one off kit for a customer and decided to put it into production. We have gone through multiple manifold designs and fabrication types, as well as multiple revisions on our final manifold design. Now that we are satisfied with the durability of the kit after being put through its paces we can announce the details and preliminary results as we continue to test the final “all out” performance and stages of power based on fuel setup (OEM, OEM+, and “ALL OUT”). At Bimmerfest East 2014 we put on display some parts from the turbo kit and fuel system. Our goal was to provide staged power in a modular form that allows the consumer to purchase the kits all together or piece by piece. So without further ado – product pictures and results from OEM and OEM+ testing. The “ALL OUT” numbers will be soon to come as we need something to keep us occupied while we finish the final stages of production on 20+ single turbo kits and fuel setups to support your power goals up to and beyond 1000hp. Disclaimer – all dynos read differently – even from one dynojet to another. Our testing was done on a DynoJet 424x. The month we took delivery of the shop car we through the car on the dyno to get baseline numbers. This specific DynoJet apparently reads a bit lower than the typical one people have been posting up. Bone stock the car produced 257whp and 260wtq. Testing and Results – OEM Fueling – 93 Octane ONLY The OEM fuel system leaves a lot of power out of reach. There are many options when it comes to achieving power beyond what the OEM system can do but many of these are not all that reliable and fall in the category of “but they work”. We feel that things shouldn’t just “work” – they should be designed, tested, and implemented. For those of you who want to make at and above the modified stock turbo housing power – and all on pump gas and stock fuel system – NO PROBLEM. The first set of testing we did was simply using a stock LPFP with a 255 inline pump. The MOTIV 750 kit is capable of running much more boost and can make far more power on 93 octane alone due to the decrease in pumping losses and efficiency. However, the HPFP began dropping fuel pressure drastically as it could not keep up with the demand (in part because the LPFP system was struggling as well). As such – this is where we felt we would stop in an effort to display a conservative showing of what the MOTIV 750 kit could do on a stock LPFP and only 93 octane. Testing and Results – OEM+ Fueling – 93 Octane ONLY After seeing just an in line pump to help the LPFP supply the HPFP we stepped up to the next level of fuel supply using a 455 in tank. The goal of this was to figure out how much further we could push the system before the HPFP showed signs of it not being able to keep up. With the aftermarket low pressure Walbro unit we were able to squeeze a bit more fuel out of the OEM HPFP allowing us to push just a little further. It's always fun to play around and see how the dynamic of the tables in the dme of the car can change with more boost less timing, less boost more timing, different cam tuning, etc. So here is a quick preview of a different profile of the map. Testing and Results – “All Out” Fueling We designed the MOTIV Single Turbo kits to be extremely efficient, powerful, consistent, and reliable. We were quick to learn that the stock HPFP (no matter what LPFP supplied it fuel) would not be enough to even find the limits of our turbo systems on regular 93 octane alone. As such we began integrating our supplemental MOTIV Port Injection fuel system. After enough testing over the previous months we can finally begin to share these results with you as well. The goal of this setup (which we have used on other platforms with great success as well) is to supply the engine fuel while taking the stress off of the HPFP and keeping it within range where the HPFP never drops fuel pressure throughout the RPM range - no matter how much power the car is making. The following were still at low boost but with the MOTIV Fuel System there is plenty of fuel for up to and over 1000hp. We are only just starting to display how much power this kit can make as this is still only on 93 octane and nothing else. The above graphs and comments have left out one major component of tuning so far. SPOOL!! Naturally, larger turbochargers require a greater amount of time to spool up and reach their respective optimal operating range. However, through tuning and an excellent VANOS system that is employed on the BMW N54 Engine, we’ve been able to alter both intake and exhaust camshaft phasing to provide more exhaust gasses into the turbine housing in order to bring the compressor up to speed faster. By increasing dynamic compression and effectively create more exhaust gas volume to enter the turbine housing we are able to speed up the spool. This comparison between an OEM and PTF calibrated VANOS system and its effects on turbocharger spool can be seen progressively in the graph below. At this point we are only starting to come into the MOTIV 750’s turbo efficiency range. The 3586 does not even wake up until approximately 24+psi and LOVES to flow upper 20s and lower 30s. So in two weeks we will be unveiling all of the results. “All Out” on race gas and e85. All out on 93 as far as we can comfortably push it. And even running a JB4 as we have been in communication with Terry for those of you would prefer to run the kit with a JB4 and his back end flash. Just for fun…here is a higher boost pull where I let off at about 4700RPM... We can’t give out too much information in one night!! Stay tuned for the remainder of that dyno pull and many more like it. In the next week or so we will begin taking pre-orders to gauge interest in how many kits we need to keep on the shelves and which turbos will be in demand. While we love people wanting to push the limits and go with bigger turbos, we do recommend sizing the turbo appropriately for your goals. Having a 900hp turbo is not fun if you only run it at 500-600hp. You will spool slower and have less power under the curve. As of now we are finishing production on approximately 20 kits. We will be offering a slightly smaller option in our 600 kit and two larger options in our 900 kit. The 900 kit can be paired with either a Forced Performance HTA3794 or a PTE6466. The 900 kit will have a little bit of lag but allow for more power on pump gas and even more when pushed all out with our full line of MOTIV horsepower solutions. The kits will retail starting at 7749 and come with all the necessary hardware needed for install. We will be doing an intro special on the first production run of 7600$ SHIPPED in the US. For shipping outside of the US please contact us. Detailed pictures to follow. The kits come with some of the most reliable and reputable turbos on the market. These are not discount turbos. They start at 2249 direct from the retailer. Forced Performance / HTA turbos are world renowned for their quality. In the meantime – enjoy this video and some pictures of the kit in the process of being made. We will begin shipping orders the first week of November.

    Dinan is a reputable and high quality aftermarket option in the BMW tuning world. However, the BMW tuning world has changed and Dinan has had to change with it. Dinan announced their piggyback tuning era (after stating piggyback tuning was inferior) earlier this year. Now Dinan releases their S1 package for the F10 M5 claiming 675 horsepower thanks to the Dinan Dinantronics performance tuner along with other supplemental modifications such as to the suspension. There are a few problems here. First of all, Dinan's piggyback box is $3,749. Why? What does it do over a JB4? What does it do over other piggyback tuning options? If Dinan wants to command the highest price point in the marketplace for a piggyback tuning box that is fine. It's fine if it's worth the money. From what BimmerBoost has seen, it isn't. Dinan can't live off his name any longer. In the old days Dinan would 'congratulate' the BMW engineers by saying they could not improve on the BMW tune (although other tuners could). Today, consumers have more options and the options other than Dinan offer more data on the performance gains and also offer their product at a comparable value. If Dinan wants to charge more that is up to Dinan but you would expect more data for the premium with Dinan's resources. Not a single timeslip? Not a single dynograph? This all goes back to Dinan's arrogance about dynographs and the white paper Steve Dinan released criticizing using dyno's for proof of gains. The reason Steve Dinan does not post dynographs is simple. It does not favor his product especially for the horsepower per dollar when it is relatively easy to compare graphs for competing products. Call this the N54 or BMS effect if you want but the BMW turbo era already proved more money does not equal more horsepower, safety, or performance. Dinan is releasing horsepower charts so clearly he sees he needs to change his approach. The Dinan name carries a lot of weight. However, it's with the uninformed. BimmerBoost users won't be ponying up for this without results to back it up. You want $13,487 for what a JB4 for a few hundred bucks with some methanol will smoke? Sorry Steve, the game has changed. You better change with it or it's game over. Dinan releases 675 horsepower tuned M-sedan that delivers supercar performance with the refinement and ride of an opulent daily driver. (Morgan Hill, Calif.) – August 2014 – BMW performance specialist, Dinan Engineering, has announced the latest addition to its signature vehicle line, the S1 M5. This twin turbocharged V8 powered sedan offers supercar performance with 675 horsepower and 644 lb-ft of torque on tap, but is refined enough to be the perfect daily driver. The 200 mph capable M-car features a comprehensive blend of components designed and tuned by Dinan, recognized for 35 years as the BMW tuning expert, to enhance every aspect of the vehicle’s performance. The S1 M5 offers the only warranty on the market that matches manufacturer coverage for 4 years/50,000 miles and on both the standard M5 and Competition Package equipped vehicles. The S1 M5 offers remarkable performance and the same warranty coverage, resale value and reliability BMW owners expect, all backed by Dinan’s nationwide network of authorized dealers and service centers. “Our goal at Dinan is to build a balanced performance package that maintains the soul of the OEM platform,” said Dinan Engineering President Steve Dinan. “This car is designed to be faster and handle sharper, but still offer the level of refinement that BMW owners expect. M-Car owners already bought the fastest BMW and now it’s up to Dinan to make it even faster” The S1 M5 makes a jump from 560 horsepower in stock trim, to an impressive 675 horsepower and 644 lb-ft of torque thanks to Dinan’s Carbon Fiber Cold Air Intake, Free Flow Exhaust system and the all new DINANTRONICS Performance Tuner that opens up the full potential of the S63 V8. The DINANTRONICS Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It was also designed to be emissions legal in 50 states (E.O. Pending). The ultimate objective was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package. To compliment the added power, the package includes negative camber front control arms, lightweight tubular Anti-Roll bars and Dinan’s High Performance Adjustable Coil-over System that gives the M5 a more aggressive stance and decreased body roll, without sacrificing ride comfort. Dinan’s adjustable coil-overs keep the factory Electronic Damper Control shocks in place and implements threaded collars to allow the user to change the ride height. The end result is a sleek lowered stance that provides improved handling to go along with the more aggressive appearance. Optional features include Dinan lightweight forged wheels (custom finishes available) and cosmetic upgrades from the BMW performance parts line that includes a carbon rear spoiler, a carbon front fascia and Dinan aluminum pedals adding a unique aesthetic touch to any 2011-2015 BMW M5. Dinan has worked closely over the years with BMW’s factory motorsports program bringing home three consecutive championships and two wins at the 24 Hours of Daytona along with countless Grand-Am podiums. With 35 years of experience building artfully engineered performance vehicles that balance tuned handling and dramatically increased acceleration with the turn-key reliability sport sedan owners demand, the Dinan S1 M5 offers supercar performance in a practical package. This package is also available for the M6 and Competition Package Equipped models.

    Here is a race we have been waiting to see. The camera car is a Porsche 911 Turbo S cabriolet. Certainly a fast car with its 550 horsepower 3.8 liter twin turbo flat-6 and PDK transmission. The car it is racing is the Lamborghini Huracan which at 3423 pounds is lighter than the 36XX pound 911 Turbo S. It also is rated at more horsepower with its naturally aspirated 5.2 liter V10 putting out 610 crank horsepower. Crank horsepower ratings do not mean as much as they used to so that is why we like to see real world comparisons. This one is interesting as the cars are incredibly close with the Huracan pulling forward in the first run and the Turbo pulling slightly in the second run. Based on Road and Track's 10.9 @ 124 1/4 mile test figures for the 991 Turbo S coupe and the 10.4 @ 135 1/4 mile test figure Car and Driver got for the Huracan this should not be close at all. Based on the result something is up with these two test figures. What is likely is that the Porsche test figure is too low of a representation and the Huracan figure is too of a representation. In practice, the cars are close enough that an extra passenger or late shift can make all the difference. Hey, you explain the race result.

    The Car and Driver Lightning Lap is one of the most interesting comparisons of the year from the major automotive publications. Car and Driver essentially takes a small group of the hottest handling cars on the market from various price points and times their laps around the Virginia International Raceway track. The full breakdown comes in the October issue and Car and Driver will post their results online at some later point this year. Here is a leak showing a quick overview of the results and there are some eye opening times. Now, VIR is not a small track and power tends to dominate. That may explain why the E63 AMG S managed a quicker lap than the BMW M4. The E63 obviously has the power advantage but a 4500 pound sedan outlapping a car a thousand pounds lighter that is not giving up all the much in acceleration and has the quicker shifting transmission? That is a head scratcher. The Porsche 918 Spyder coming out on top is no surprise. At over a million dollars, it better. The Camaro Z28 beating the Porsche 911 Turbo S and Corvette Stingray is also no surprise but certainly impressive. What Chevrolet accomplished with the Camaro chassis is well worthy of respect. The other results are all below. Further details will come once Car and Driver sells their magazines and posts the full results online:

    Dinan continues to roll out more of their piggyback tunes for the newer turbo M cars. Their latest Dinantronics tune tackles the new F80 M3 and F82 M4 equipped with the S55 inline-6. The $2499.00 Dinan box raises output on 93 octane from the factory 425 horsepower to a Dinan claimed crank output of 516 horsepower. Torque goes up from 406 lb-ft at the crank to 489 lb-ft for a gain of 83 lb-ft as measured at the crank. Now, we know the M3 and M4 are very underrated from the factory to begin with. How is Dinan measuring the horsepower here? We do not doubt the power and torque gains whatsoever but the M3 and M4 are making close to 500 horsepower off the showroom floor. This is why we want to see output at the wheels, not at the crank. Quoting crank figures with modern turbo cars is a tuner relic. Obviously, the main competition here is going to come from BMS. The BMS M3/M4 JB4 box costs $799.00. BMS has shown over 500 horsepower at the wheels already with this tune. Frankly, BimmerBoost believes BMS prices the F80 M3 and F82 M4 JB4 at $799.00 because if it was any more of a value M owners would probably consider it a 'cheap' piece of a equipment. BMS has room to drop the price but Dinan's pricing means they do not have to. It certainly will be interesting to see some real dyno results as well as real world performance numbers. People buy tunes to be faster. Which piggyback tune is the fastest? Well, we all already know the most expensive tune is not necessarily the fastest tune. Product Description Stage 1 (DINANTRONICS™ Performance Tuner ONLY) Maximum Power: 516 HP, 489 lb-ft of torque. The DINANTRONICS™ Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It was also designed to be emissions legal in 50 states (E.O. Pending). The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package. The Dinan® Difference The biggest benefit of the DINANTRONICS™ Performance Tuner is our ECU has the… "…capability of setting an optimum target lambda (fuel mixture) as well as correcting short term trim which is the difference between target and scheduled fuel mixture. By matching these two correctly we can reduce knock sensor activity which will make smoother performance, protect the catalyst, increase power and allow us to make it emissions legal."- Steve Dinan The Dinan® Difference is possible by employing a full staff of talented engineers that are well rounded in all aspects of their job. Manipulating these signals with an adept hand all the while keeping an engine running at its best and with the most reliable power is what Dinan is all about. Well Engineered Plug-in tuning devices all have one thing in common, they send a modified signal to the factory ECU, telling it the boost pressure is below target values. This then causes the factory ECU to raise the boost pressure to what it thinks is the correct value. This modified boost pressure signal causes errors in fuel mixture and ignition timing. These errors can cause the on-board diagnostics systems to set faults, but they can also cause exceedingly high catalyst temperatures and a loss of power. In addition, when power is increased, exhaust gas temperature will increase as well and this must be countered with a slightly richer air/fuel mixture. The DINANTRONICS™ Performance Tuner uniquely has the capability to adjust target Lambda, correct short term trim as well as ignition timing errors induced by raising boost pressure. This enables Dinan calibration engineers to optimize air/fuel mixture and ignition timing at elevated boost pressure throughout the entire gamut of engine RPM and engine load. Additionally, the ability to correct short term trim corrections (the difference between target and scheduled fuel mixture) remain within OEM specifications. This minimizes knock sensor activity, which in turn means smooth engine performance, catalyst protection and power increase, while this is also required to make the car emissions legal. Dinan engineers have worked for two years on the DINANTRONICS™ Performance Tuner in efforts to provide BMW enthusiasts with Performance without Sacrifice. State-of-the-Art Hardware The DINANTRONICS™ Performance Tuner is engineered using the best possible components and advanced hardware. The most obvious and visible component is the elaborate wiring harness. Using OE connectors and an expandable braided wiring sleeves ensures that all visible components appear as if they come straight from the factory. More importantly however it guarantees long lasting and dependable performance due to the use of high heat, moisture and abrasion resistant materials and design. The other hardware element involved is the Dinan electronic control unit (ECU) itself. While its outward appearance may seem tame, the processing power and sophistication held within its internal circuitry is anything but. Capable of delivering signals to various systems at an astonishing 4000 times per second the DINANTRONICS™ Performance Tuner yields the power to control all current signals delivered to the ECU as well as those developed in the future without a hiccup in performance or reliability. This immense processing power equates to a high degree of engine control resulting in a much lower likelihood of setting a fault. In addition smoother running conditions and superior drivability are achieved, all of which are Dinan hallmarks. Unmatched Warranty Dinan's comprehensive warranty program, introduced in 1997, provides superior warranty coverage to that which you would find elsewhere. If your vehicle is currently covered by the vehicle manufacturer's new car limited warranty, Dinan® products are warranted for the remaining term of the vehicle manufacturer's new car limited warranty. The manufacturer's new car warranty is limited to 4 years or 50,000 miles (80,000 kilometers in Canada), commencing on the date of first retail sale or the date the vehicle is first placed in-service as a demonstrator or company vehicle, whichever is earlier. Dinan's warranties are transferable when ownership of the vehicle into which the Dinan® products were originally installed is sold. BMW automobiles can now be performance-tuned without the associated concern of negatively affecting the new car warranty coverage. Designed to be Emissions Legal The DINANTRONICS™ Performance Tuner was designed and built to be the only tuning box on the market that is emissions legal in all 50 states. At the moment this product is emissions legal in most states – the product is in compliance with US Federal EPA Memorandum 1A, or this product has not been found, nor is believed to be, unlawful for use under the provisions of the Clean Air Act. Currently this product is not legal for sale or use in California, and states that have adopted California emissions standards, on any pollution controlled motor vehicles. We are however in the E.O. process with the ARB and are confident that the DINANTRONICS™ Performance Tuner will be emissions legal in all states in the near future. Drivability There is more to a tune than just cranking up the boost. Power needs to come on smoothly and in a predictable way to make the car as fun to drive at wide open throttle as cruising around town. It is your BMW, but reborn with new found acceleration and speed. Installation Plug-and-Play installation in two hours or less at any of the 180+ Dinan® Dealers. While firmware is loaded directly on the ECU the model specific software will need to be downloaded into the ECU by an authorized Dinan dealer after installation. Log on to www.dinancars.com to find your nearest dealer or contact Dinan to make an appointment. Easy To Use Dinan's ECU is Bluetooth® Smart meaning that you can change maps simply via a Bluetooth connection. Just install and you are done! Designed for the Future The DINANTRONICS™ Performance Tuner was engineered with future expansion of functionality in mind. Boasting the most powerful processing power on the market the DINANTRONICS™ Performance Tuner can handle more functions and processes than any of its contemporaries. To that end the Dinan performance tuner is capable of interfacing with the CAN and FlexRay communication systems which allow for controlling powertrain functions, among others. This means that when new functions are developed there will be no need for a new box, just a short software update at your local Dinan dealer. Satisfaction Guaranteed Dinan guarantees you will be impressed by the DINANTRONICS™ Performance Tuner and the performance it provides that we offer a 3-Day return policy. If you aren't satisfied with what the Dinan solution brings to the table within 3 days of install you can go back to your dealer for a full refund (installation labor costs still apply).

    Very interesting video here that helps put Porsche 991 Turbo S performance into perspective. A video from last week raised some eyebrows as a 991 Turbo S cabriolet put up a very strong showing against a Lamborghini Huracan. According to magazine test numbers that should not be possible the video is what is. So how does the Porsche 991 Turbo S coupe do against the big brother to the Huracan the Aventador? Well, the 991 Turbo S again appears to overachieve. Off the line the 991 Turbo S takes the Aventador out of the hole and manages to open a gap of a couple car lengths. In theory the Aventador and its 700 horsepower from the 6.5 liter V12 should be able to run down and pass the 991 Turbo S with its 550 horsepower. The turbo torque combined with the PDK makes that easier said than done. The 991 Turbo S is able to hold its lead through the kilometer, impressive. The Aventador does have the higher trap speeds though indicating it would pull had it gotten a better launch. The 1/4 mile trap speed for the Aventador is 127.53 compared to the 991 Turbo S 126.878. Just over a one mile per hour difference. However, by the kilometer mark the trap speed difference is almost 3.5 miles per hour so still close but the Aventador is pulling harder as speeds and distance increase. It is not pulling hard enough to make up for the difference out of the hole and the extra few hundred pounds it carries no doubt play a role (plus the weight of the passenger which the 991 Turbo S does not have). The 991 Turbo S definitely appears to overachieve especially for a stock car.

    A Volkswagen Golf R going up against a tuned F13 M6? Sounds like a mismatch and normally it would be if this particular Golf R did not the have the HGP 3.6 liter VR6 turbo package. HGP Golfs have shown great results against stout opposition such as a Ferrari 458 Speciale, tuned Nissan GTR, and an Evo X with a turbo upgrade. The first race in the video has the M6 and HGP Golf square off and the Golf beats the M6. It is important to note the Golf R has all wheel drive traction which really helps it as the 1/4 mile elapsed time of 10.672 for the Golf R versus 11.910 for the M6 shows. The Golf also beats the M6 to the kilometer marker getting there in 19.366 seconds whereas the M6 takes 20.770 seconds. The M6 is pulling harder at the kilometer marker by 2.5 miles per hour. The next run has the HGP Golf go up against a stock Lamborghini LP560 Gallardo. Power is on the side of the Golf with its roughly 700 horses. The Gallardo gets a nice jump off the line but the Golf has no trouble running it down and passing it. The HGP Golf R is much quicker than the LP560 out trapping it by almost 20 KPH in the standing kilometer which is certainly impressive. A Golf clowning a Gallardo? Yep. The final run is the HGP Golf versus a Gorilla Racing Stage 3 CLS63 with a claimed output of 840 horsepower. The CLS63 AMG should take the run based on that output figure but struggles with the Golf which beats it badly off the line. The CLS63 AMG can not make up the gap and is beaten soundly although it is pulling just under 6 KPH harder by the kilometer marker. From a roll the CLS63 AMG would win but if it can not run down the Golf in over a half mile, well, that shows just how impressive the HGP Golf is. The HGP Golf R beats all three cars it goes up against and although it does not have the outright fastest trap speed it has plenty of power and is able to put its power to the ground. Sometimes that is more important than peak horsepower figures.

    The official reveal will take place today but photos are already circling the internet showing the final AMG GT design. Reaction will no doubt be all over the place on the car. The styling is not quite as revolutionary as AMG implied it would be. The final design obviously is not shocking but it is also not quite as aggressive as what Autocar showed and stated the final design would be. Is this car really pushing the Mercedes design language forward? It really just looks like a Mercedes SL and an S-Class coupe had a baby. It takes design cues from the other Mercedes vehicles in the lineup and just meshes them together. The look is somewhat lazy as it is almost as if they just mixed and matched headlights and taillights from the other vehicles. What do you think?

    We've taken a look back at our history and picked five styles to refresh with a modern twist; introducing the Classic Series. We found inspiration in iconic sports cars like the Ferrari 512TR, Porsche 964, BMW E36 M3, Acura NSX and even German wagons like the W124 Mercedes-Benz E-Class. The new Classic line debuts with five new styles including the 300 mesh, the 301 split-9-spoke, the 303 13-spoke, the 305 5-spoke and the 309 19-spoke. The Classic line is available in diameters ranging from 18 to 22 inches and widths range from 7 to 14 inches. Features include a modern conical profile with clean and simple spoke designs that highlight the style of wheels and cars before the domination of modern era of automation and electronics. This simplicity in the designs also allows HRE to offer these wheels at prices that are significantly lower than their more complex designs.

    Another great video here from Russian BenzBoost member Vasily1. His Renntech turbo upgraded W212 E63 AMg S 4Matic has just been crushing whatever it runs into on the highway. He has run a Lamborghini before although that was the big boy Aventador. The result was the E63 AMG S making fairly easy work of it showing that this Renntech has this W212 E63 AMG S 4Matic putting out over 850+ horsepower with their turbochargers. Does the less powerful but lighter Huracan fair better than its big brother? Nope. The Huracan is very quick as European test figures show but the Huracan is not faster than the Aventador and in turn it is not faster than this E63 AMG S 4MAtic. The Huracan does do very well when starting from a low speed where its shift speed advantage keeps it in the race but once hitting the higher speeds the power deficit shows. Great runs and a great video.

    Another member joins the BMW N54 700 wheel horsepower club. The Ventura Motorsports top mount single turbo N54 kit powered by a Comp Turbo 6465 turbocharger went over the 700 wheel horsepower mark with a 709.56 peak power Dynojet pull. The peak torque figure achieved is 659.26 pound-feet at the wheels. This was done on a Dynojet in STD correct in relatively warm California weather. Complimentary modifications are a VRSF charge pipe, Tial BOV (blow off valve), VRSF 7" intercooler, Walbro 255 inline fuel pump, BMS methanol kit with two CM10 nozzles, Spec Stage 3+ clutch with single mass steel flywheel. Tuning is courtesy of a JB4 with complimentary custom software flashed courtesy of the BimmerBoost.com software. Peak boost achieved is 30 psi and it tapers to roughly 27 psi toward redline. The fuel is an E40 blend and 100% methanol is being injected. Great results and there are now a small handful of N54's crossing the 700 wheel plateau with this being the latest car to do so.

    11 second BMW X1? Yep. Congratulations to BimmerBoost member paradoxical3 who managed to break into the 11's with his modified BMW X1. He had Pure Turbo modify the OEM N55 turbocharger and the result is a 11.930 @ 116.11 in the 1/4 mile. Yes, that is quicker and faster than a BMW X5M with its 560 horsepower S63 5.5 liter twin turbo V8. A modified X1 can easily run with the big boys and shows how important power to weight is. This 11.930 @ 116.11 pass improves quite a bit on @paradoxical3's bolt on performance which produced a 12.137 @ 111.20 in the 1/4 mile. The car clearly gained quite a bit of horsepower with the turbo upgrade as evidenced by the trap speed and there is also definitely more in it as the tuning evolves. Timeslip and further details in the owner's own words below: Paradoxical3: If you have been following my thread (http://www.bimmerboost.com/showthread.php?54528-X1-35i-M-Sport-Track-Daily-Driver-Build) you will see that I have been trying to build the best all around BMW X1 I can - able to run a sub 12 second 1/4 mile, lap mid-ohio faster than a M3, and retain the luxury and utility of the vehicle for the perfect daily driver. I am one step closer to my goal today as I have furthered my N55 xdrive record with a 11.930 pass at Tri State raceway. This was my first time to the track with the Pure Turbo upgrade and there is at least another mph trap speed in it once I refine my boost targets. I am bumping into the limits of the tmap sensor not being able to read over 21psi, as well as the JB4's 21psi failsafe (I kick to failsafe mode sometimes after shifts due to boost spike). I am guessing I will wind up around 11.7 here. There were a few passes with better launches and higher speed (93mph by the 1/8) but I always hit boost safety during those. Mod list: X1 35i M-sport JRZ RS1 coilovers Pure Turbo N55 Stage 1 BMS JB4 ISO with flexfuel wires BMS Intake BMS downpipe ER intercooler/chargepipe NGK plugs Apex wheels with Direzza Zii 50% e85 mix - I REALLY need a new fuel pump to make this percentage mix stable. Here is the timeslip, a video of the run (against my friend and very fast Camaro SS, also an 11 second car), and my log. http://www.datazap.me/u/paradoxical3/11930-x1-14-mile I am also proud that this is not just a straight line car! I am very happy with the Pure Turbo setup. I am already 5+mph faster in trap in my first try and it will probably wind up with 6-7mph faster. For the $850 price I got in the group buy, it is the cheapest power available and makes the car a LOT more fun.

    If you are looking for a sporty German drop top capable of seating four people here are three very good choices. The Audi S5, BMW 435i, and Mercedes E400 are all worthy choices. The question is, which is the best of the group? Well, Sport Auto fortunately decided to do a comparison with data and even took the cars out of on the Hockenheim course. So how do they stack up to each other? Well, the S5 blows the other two cars away especially the BMW 435i which gets stomped by both the Audi S5 and the Mercedes E400. Keep in mind the E400 is sporting the new Mercedes M276 DELA 35 3.5 liter turbocharged V6 powerplant. This engine offers 333 horsepower and 354 lb-ft of torque. The E400 offers the most torque out of the group with the S5 at 325 lb-ft and the 435i at 300 lb-ft. The 435i trails both the S5 and the E400 by 33 horsepower. What the 435i has going for it is the lightest curb weight but it doesn't matter on the track. It has the slowest laptime of the group. It lags behind the S5 by 3.6 seconds around the Hockenheim which is an eternity. It is also 2.2 seconds behind the E400, ouch. What happened to BMW's sporty character? The S5 is chosen as the best of the three cars and Sport Auto states it isn't even close. The E400 is chosen second and the 435i takes last place. Have Audi and Mercedes really improved that much or has BMW become far too complacent? You be the judge.

    This is not the first time we have seen a modified M157 Mercedes AMG beat a Lamborghini Aventador. A Benzboost member who has an E63 AMG S 4Matic with Renntech upgraded turbos has been beating up on just about everything including the Aventador. This CLS63 is not the 4Matic all wheel drive variant however but the pre-facelift rear wheel drive model which is lighter. It does however feature the same basic M157 twin turbo 5.5 liter V8 AMG motor. So how do the Kleemann K3 M157 upgrades show? Very well as the CLS63 AMG is able to open up a small lead on the Aventador. Up top, it appears the Aventador starts to pull but both cars shut down as they approach traffic. Considering the Kleemann K3 upgrade consists of just exhaust and ECU modifications (although further details are hard to find on the Kleemann website which really needs some work) the run certainly is impressive against an opponent like the Aventador with its 700 horsepower 6.5 liter V12. Turbo torque isn't easy to beat:

    Twin turbo builds are becoming increasingly popular for the W211 E55 AMG and M113 V8 based cars in general. These builds are not cheap as custom manifold work was necessary to fit a pair of Garrett GTX3076R turbochargers but swapping out the factory M113K blower for a pair of turbochargers offers numerous advantages. The main one being less parasitic loss and additionally greater power capability with easier boost adjustment. No need to swap pulleys with turbos. This particular car belongs to BenzBoost member @redbulljunky who took his car to the strip in the summer heat and managed a respectable 10.8 @ 129 in the 1/4 mile in 24XX foot density altitude on only 14 psi of boost. Keep in mind, this is on the stock motor. With a built motor and the turbochargers cranked up on race gas we can expect a hell of lot more out of this car. The main thing to take away from this is that tuning for turbos on the W211 E55 is evolving and for those seeking very big power on the platform a turbo setup is well worth a look although it certainly will not offer the cost or convenience advantages of the supercharger upgrade kits on the market. <iframe src="//instagram.com/p/sdSIEwlTde/embed/" width="612" height="710" frameborder="0" scrolling="no" allowtransparency="true"></iframe>

    What is it about the craziest BMW's coming from the Scandinavian countries? Here is a nice example from Sweden. The owner took an E30 3-Series, swapped in an S54B32 from an E46 M3, and threw an 80mm top mount turbocharger on it. PPF (Pure Performance Factory) in Sweden did the engine build work and tuning on this car and the result with E85 fuel at 2.2 BAR (31.9 PSI) of boost is 1060 horsepower to the wheels. Yep, 1060 wheel horsepower (and 833 lb-ft of torque) in a car weighing somewhere around 3000 pounds. That makes for a power to weight ratio of epic. Just take a look at the pictures and video of the car in action below. Much respect from BimmerBoost to our Swedish friends:

    Two turbocharged all wheel drive german luxury performance sedans going at it here. The Audi RS7 offers 560 horsepower stock from a 4.0 liter twin turbo V8. The Porsche Panamera Turbo has a larger 4.8 liter V8 that is also twin turbocharged but it is less powerful rated at 520 horsepower. Porsche offers an optional power kit for roughly $20k that boosts the output into the 540 horsepower range thanks to upgraded turbochargers and more aggressive tuning. The Porsche Panamera Turbo uses a PDK dual clutch transmission whereas the RS7 uses a more traditional automatic. The weight between the two is a wash in the 44XX range. We have already seen the RS7 beat the Panamera Turbo decisively in a straight line but does the power kit change the outcome? No, the RS7 is still faster. Even if the more powerful Panamera Turbo S with its 570 horsepower were put in place of this Panamer Turbo the RS7 still looks like it is too strong to overcome. The RS7 despite its smaller motor and lack of a dual clutch transmission simply is the stronger car especially considering just an ECU tune gets it into the 10's in the ~130 trap speed range. The RS7 is a beast.

    A sport utility vehicle against a BMW M car? The thought used to be absurd. The thought of Porsche producing an SUV used to be absurd too. Times have changed and now we have two Porsche SUV's with the Macan Turbo being the newest entry into the Porsche performance SUV lineup. Quite the entry it is with its 400 horsepower 3.6 liter V6 engine, all wheel drive, and 7-speed dual clutch PDK transmission. On paper the two vehicles are close in power but the edge goes for the F80 M3 and the edge in power is considerable. First of all, the F80 BMW M3 is very underrated in its output. It is closer to 500 horsepower than 400 horsepower. It also is not sending power to all four wheels but the rear wheels making for lower drivetrain losses although it also makes it harder to launch off the line. Both vehicles have dual clutch transmissions so that is a wash. The Macan is heavier by roughly 700 pounds. The way the race should play out is the Macan getting a slight lead and then the M3 should pull past it after second gear and keep pulling with relative ease. That is exactly what happens. The M3 destroys the Macan Turbo which is no slouch with its 0-60 in 4.5 seconds, 0-100 in 11.1 seconds, and 13.1 second 1/4 mile. The M3 just has too big of a power to weight advantage with 0-100 coming in 8.6 seconds and the 1/4 mile in 12.4 seconds. Past 100 this is no longer a race especially as aerodynamics at higher speeds favor the M3.

    With the new turbocharged V8 era one issue the heavy AMG sedans face is heat soak. This is especially prevalent after multiple WOT (wide open throttle) runs and exacerbated by high summer temps or warm climates. To prevent heat soak which will cause a loss of power cooling upgrades are necessary. This is especially true on modified cars which of course will generate even more heat and likely be driven aggressively. AMS has a solution with their boost cooler system to maintain optimum performance. The system drops temps by almost 60 degrees according to AMS testing which is a very large temperature drop. Further details on the $2695.00 system (available for pre-facelift E63 and CLS63 RWD models) including what it contains as well as design choices below in the words of AMS: The Alpha Performance E63 (W212) 5.5L Bi Turbo Boost Cooler System is a great addition to your M157 equipped AMG whether your car is stock or modified. The cooling system features a large, high efficiency heat exchanger located at the front of the car, a reservoir that holds over a gallon of coolant in the passenger front fender well and a high flow brushless pump which runs complementary to the factory pump. Whether you live in a hot climate area, enjoy long spirited drives in the mountains or long high speed pulls on airstrips, the M157 Boost Cooler will keep your intake temps low and maintain your AMG’s maximum output no matter the ambient conditions. As with all Alpha Products, everything needed to install the system is included – bolts, fittings, lines etc. Best of all, no drilling on the car is required. Hard ‘Core’ The most important part of an efficient heat exchanger system is the core, skimping here could mean the overall performance of an ‘upgraded’ system might be worse than stock! Our Alpha core is a high quality, made in the UK, double pass design where the coolant makes two passes through the unit vs competing products which use a single pass design. Our unit works with the factory heat exchanger giving you a significant boost in cooling power. Innovative Reservoir Means Zero Lost Trunk Space! The hand fabricated Alpha reservoir acts as a large heat sink to keep coolant temperatures low and stable. With over a gallon of additional coolant on board, it increases the cycle time allowing it to dissipate more heat before being recirculated, working as a large thermal reservoir, keeping the horsepower-killing heat soak at bay. With its trick mounting location in the passenger fender well, you don’t have to worry about running lines to the rear of the car, drilling holes in your trunk's floorboard, or giving up valuable trunk space! Pumped up! To give you the best possible performance and keep the coolant flowing efficiently through the heat exchangers, we added an additional high flow pump to run in conjunction with the OEM pump. The combination of the two pumps allow a high flow rate to keep the fluid moving and maintains that flow rate at higher pressures giving you the assurance your car will stay cool in hot climates or on those top speed pulls.

    This is going to be a very popular drop top considering that the F22 2-Series coupe is already a hit. The car is priced well starting at $38,850 for the rear wheel drive N20 powered F23 228i and this price rises to $40,650 with optional xDrive all wheel drive. An all wheel drive BMW drop top? Yep, the people who have to deal with snow are going to love this. There also is of course the M235i drop top with the N55 inline-6 engine and it starts at $48,650. The jump up in power and torque with the M235i comes with the sacrificed of the xDrive all wheel drive option. A bit of a bummer for those who wanted the larger motor with all wheel drive. As the F22 coupe is offered with an M235i xDrive model it certainly is possible that an all wheel drive M235i convertible will be added to the lineup at a later date. BMW calls the M235i the first 'open top' M Performance Automobile which technically is true. It is not an M car but an M Performance car. Apparently pointing out that this is the first drop top M Performance Car matters. There are no surprises here. The F23 offers the same drivetrain as the F22 coupe with the exception of the xDrive M235i. Dropping the top brings with it a $5,750 penalty. Further details available in the press release along with the official photos below. The New BMW 2 Series Convertible  Style and dynamics of the acclaimed BMW 2 Series Coupe combined with open-air driving  Available in the US as 228i and M235i  All-wheel drive 228i xDrive available from launch Woodcliff Lake, NJ – September 9, 2014 6:00pm EDT/3:00pm PDT. . . Few new cars have been more anticipated than the BMW 2 Series Coupe when it arrived in early 2014. Hot on the heels of the widely acclaimed BMW 228i and M235i Coupe, BMW announces the new BMW 2 Series Convertible. Available in the US as the 228i and M235i, the 2 Series Convertible blends the style and dynamic driving character for which the 2 Series Coupe is already renowned with the open-air pleasure of a folding soft-top. The BMW 2 Series Convertible will make its world debut at the Paris Motor Show. The 2015 M235i and 228i as well as the 228i xDrive, featuring BMW's intelligent all-wheel drive system, will arrive in US showrooms in early 2015. The 2015 BMW 2 Series Convertible will be offered at a Manufacturer's Suggested Retail Price of $38,850 for the 228i, $40,650 for the 228i xDrive, $48,650 for the M235i, including $950 destination and handling. The BMW 2 Series Convertible follows in the tire tracks of the pioneer and undisputed leader in its class - the BMW 1 Series Convertible. The 1 Series Convertible entered the fray as the first open-top premium model in the sub-compact segment, went on to defend its position as clear market leader against subsequent pretenders to its throne, and achieved sales figures in excess of 130,000 units worldwide. The development team for the new BMW 2 Series Convertible has focused squarely on building on the strengths which proved pivotal to this success. With even more grace, athleticism and sharpness about its design, clear advances in terms of performance as well as efficiency, and improvements in the driving comfort, functionality and innovative equipment features it offers, the BMW 2 Series Convertible takes the qualities displayed by its predecessor to a new level. The number 2 has a special importance in the model history of BMW and, since the arrival of the BMW 02 range more than 45 years ago, has represented exceptionally sporting driving pleasure in a subcompact car. Introduced in 1966, the 02 series went on to become a byword around the world for sporty, agile handling – and from 1967 these gifts could also be enjoyed with the roof down. Specialist coachbuilder Baur wasted little time in developing a pair of soft-top variants based on the BMW 02 range which were produced until 1975. Elegance and openness in the established style of BMW Convertibles. The exterior design of the BMW 2 Series Convertible displays the typical characteristics of an open-top four-seater from the Bavarian brand. The BMW 2 Series Convertible combines a low-slung silhouette and dynamically stretched lines with compact proportions and powerfully contoured surfaces. As with the 2 Series Coupe, its distinctive looks underline its standalone status in the brand's model line-up and spotlight the dynamic potential, exhilarating open-top driving experience and premium characteristics which customers can expect. All in all, the eye-catching features which distinguish the BMW 2 Series Convertible from its rivals need no second introduction. Opening the standard electrically-operated soft-top roof highlights the harmonious transition between the exterior and interior. The shoulderline and soft-top compartment create a level surface that wraps around the passenger compartment and evokes the distinctive "boat deck" character of BMW Convertibles. The rollover bars, which remain out of sight unless deployed as required, also contribute to an overall impression dominated by large level surfaces. The design of the interior is headlined by modern functionality, high- quality materials and the driver focus for which BMW is renowned. And exclusive accents in the center console help to give the BMW 2 Series Convertible a refined premium feel in keeping with the car's character. Hallmark BMW design language, classical features of a BMW Convertible. The front end of the BMW 2 Series Convertible, which adopts the brand's familiar design language, exudes power and presence. As with the BMW 2 Series Coupe, front-end structuring comes courtesy of lines that converge dynamically on the large, slightly forward- slanting BMW kidney grille. The contours of the twin circular headlights narrow at their inner extremes and are replicated by the outlines of the outer air intakes. Air into the front apron serve to channel the onrushing air precisely behind the front fenders, reducing turbulence in the wheel arches. The headlight units are separated from the BMW kidney grille by narrow strips on either side. An LED accent strip – or, if the Xenon lights are fitted, an LED accent light – cuts across the top of the headlights. Curtains integrated into the front apron serve to channel the onrushing air precisely behind the front fenders, reducing turbulence in the wheel arches. The headlight units are separated from the BMW kidney grille by narrow strips on either side. An LED accent strip – or, if the Xenon lights are fitted, an LED accent light – cuts across the top of the headlights. Together, the level shoulderline of the BMW 2 Series Convertible and the car's telltale BMW proportions – the product of short overhangs, a long hood, long wheelbase and set-back passenger compartment – create an ideal environment in which to enjoy an exhilarating open-top driving experience. The positioning of the seats well back in the body gives the driver and passengers an up-close-and-personal experience of not just the onrushing wind and the sun's rays but also the transfer of power to the rear wheels. Its shoulderline rises slightly to the rear and merges into the virtually horizontal trunk lid. And it links up with the prominent swage line running alongside it, through the door handles and into the rear, to create a dynamic wedge shape which captures the forward-surging urgency of the BMW 2 Series Convertible. Additional character lines leading from the doors and side skirts to the rear fenders divert the eye to the powerfully formed surfaces around the rear wheel arches, which duly focus attention on the car's rear-wheel-drive set-up. The BMW 2 Series Convertible's body is at its widest around the rear wheels. The rear lights, which extend well into the fenders, display the familiar BMW L-shape and have LED- powered light strips. The third brake light is integrated into the trunk lid and likewise illuminates using LED units. The interior: driver-focused cockpit, cutting-edge functionality, refined premium ambience. The arrangement of displays and controls familiar from other BMW models gives the BMW 2 Series Convertible's cockpit a familiar driver focus. The surface structure of the instrument panel, center console and door trim follows the overlapping principle known as "layering". The bespoke design of the BMW 2 Series Convertible's center console creates a refined premium feel on board. The controls for the audio system and climate control are set against high-gloss black surfaces, and the air vents have chrome surrounds. These elements are joined by an exclusively designed display for the climate control system with white readouts on a black background. An array of stowage areas and large storage compartments in the doors, meanwhile, contribute to the modern functionality of the interior. Sport Line and M Sport provide greater individualization. As the first open-top M Performance Automobile, the M235i Convertible has all the elements to maximize the performance potential of the 2 Series Convertible. Customers of the 228i Convertible tempted to look beyond standard specifications will be able to order one of two lines in the US each of which offer individualization through the use of tailored design and equipment features. Sport Line adds 18-inch light-alloy wheels in their own exclusive design plus sport suspension (not available with xDrive) special door sill strips, seat upholstery, interior trim strips and car key designs. M Sport also comes with its own unique trims, car key, plus an M Sport aerodynamic body kit developed specially for the BMW 2 Series Convertible. The surrounds for the outer air intakes, the front of the kidney grille bars, the cross rib in the central air intake and the rear apron all have a high-gloss black finish in the Sport Line. These details join together with a reduction in the number of kidney grille bars from 11 to 8 and exhaust tips in black chrome to highlight the dynamic character of the BMW 2 Series Convertible. Sport seats for the driver and front passenger, a specially styled instrument cluster and a knee pad on the driver's side of the center console heighten the sense of sporting flair in the interior. M Sport, on the otherhand, also comprises sport suspension tuning, including a 10-millimeter drop in ride height (not available on xDrive). In addition, it features 18-inch M light-alloy wheels in double-spoke design, aerodynamically optimized body elements (including large front air intakes, eye-catching side skirts and a diffuser for the rear apron), as well as a special design for the BMW kidney grille and a exhaust tips in high- gloss chrome. In addition to aluminum door sill strips bearing the M logo, features such as sport seats for the driver and front passenger, Aluminum Hexagon interior trim strips with an accent strip in Estoril Blue, an M leather steering wheel, a special dial design for the instrument cluster, and an M driver's footrest also combine to bring an aura of sporty driving to the interior of the BMW 2 Series Convertible. The Track Handling Package, which is available on the 2015 228i Coupe, will also be available for the 228i Convertible. Inspired by the original formula of BMW "S-package" vehicles manufactured in the course of the past three decades, the new Track Handling Package embraces the desires of the most enthusiastic BMW drivers. It includes the Adaptive M Suspension, Michelin Pilot Super Sport tires on unique 18-inch light-alloy wheels, Variable Sport Steering, and M Sport Brakes. The fabric soft-top opens and closes in 20 seconds, even when on the move; three color variants, optimized acoustics. The lines of the multi-layered fabric roof emphasize the dynamic looks of the BMW 2 Series Convertible. The soft-top's classic, pared-down appearance exudes a feeling of lightness and is complemented by optimized acoustics and unrestricted year-round usability. Soundproofing has been improved compared with the car's predecessor through the introduction of additional insulation for the soft-top skin. This measure cuts interior noise by 5 dB(A) in the front seats and 7 dB(A) in the rear. When spontaneous open-top driving pleasure is the order of the day, the standard electrically operated soft-top can be opened in 20 seconds at the touch of a button – and it also closes in the same small sliver of time. The opening/closing process can also be initiated while on the move at speeds of up to 30 mph (50 km/h). If the car features the Comfort Access option, the roof can also be opened and closed remotely. As an alternative to the standard Black, the fabric soft-top can be ordered in two optional colors. For the Anthracite with silver effect top and Brown with silver effect option, the fabric of the cover is interwoven with fine shiny fibers. This gives the material a high-quality, shimmering metallic surface impression, producing attractive reflections under sunlight. Increased spaciousness, load capacity and variability. The increased exterior dimensions of the BMW 2 Series Convertible over its predecessor mean occupants in the four seats can enjoy extra spaciousness and freedom of movement. In addition, the access space through to the rear is now 0.4 inches larger, which, when combined with the standard Easy Entry function for the front seats, means that using the rear seats is a significantly more comfortable experience. The interior and trunk space can now be used in a wider variety of ways. SAE volumes are not yet available, however, by EC measure the trunk capacity has increased by nine percent with the roof closed and seven percent when the top is folded. The width of the opening to the load area between the rear lights has been increased by 1.4 inches. The soft-top compartment can be raised using a lever in the trunk, increasing capacity. A through-load is standard on the BMW 2 Series Convertible. The aperture between the trunk and rear compartment, available for use when the rear seat bench is folded down, has been expanded in width by 5.9 to 17.7 inches and in height by 1.1 to 9.7 inches. As a result, owners can now transport two 46-inch golf bags, for example, or a pair of snowboards. With large door pockets, a larger glove compartment, two cupholders in the center console and a storage compartment under the armrest, the BMW 2 Series Convertible also offers increased stowage capacity inside the passenger compartment. The lower section of the door trim offers space for drinks bottles up to one liter in size, while the standard storage package includes cargo nets on the backs of the front seats and securing lugs and nets in the trunk. BMW 228i Convertible: Power for typical driving enjoyment with efficiency. Aided by BMW TwinPower Turbo technology with twin-scroll turbocharger, High Precision Direct Petrol Injection, VALVETRONIC fully variable valve lift regulation and Double-VANOS variable camshaft timing, the four-cylinder engine of the BMW 228i Convertible generates maximum power of 240hp between 5,000 and 6,500 rpm from a displacement of 2.0 liter. Its peak torque of 255 lb-ft can be harnessed all the way from 1,450 to 4,800 rpm for sporty power and performance. Mated to an 8-speed sport automatic transmission, the 228i Convertible will accelerate from 0-60 mph in 5.7 seconds. The quick-shifting 8-speed sport transmission includes steering wheel shift-paddles which allow the driver to intervene manually when desired, while a Launch Control function provides the best possible traction and dynamics when accelerating from standstill. This increase in performance also comes with greater efficiency. While EPA numbers are not yet available for the 228i Convertible, for sake of comparison, the 228i Coupe is more than 30 percent more efficient than its 128i Coupe predecessor. BMW xDrive intelligent all-wheel drive system available from launch In a first for BMW in this class of premium convertible, the 228i Convertible will be available with xDrive, the company's intelligent all-wheel drive system right from launch. The 228i xDrive sprints from 0-60 mph in just 5.6 seconds. BMW xDrive is unique in design and construction. In normal conditions, driving torque is always transmitted to the rear wheels, and most of the time to all four wheels. Normal torque split is 70% rear/ 30% front. The portion of torque transmitted to the front wheels is controlled by a multi-disc clutch that can be fully open, fully engaged or at any level of partial engagement in between. The torque split between rear and front wheels is thus steplessly variable. The clutch is directed by an electronic control system in response to actual road and driving conditions. This gives xDrive a dynamic ability that is unparalleled by other all-wheel drive systems. xDrive does more than just optimize traction; it can also enhance both agility and stability on grippy as well as slippery road surfaces. Using the same type of logic that Dynamic Stability Control employs to recognize and correct for excessive over- or understeer, xDrive adjusts the front/rear torque split to avoid these tendencies. If the system senses oversteer, it closes the multi-disc clutch completely, sending the maximum possible torque to the front wheels. In the case of excess understeer, xDrive opens the clutch completely, sending no driving torque to the front wheels. Driving Dynamics Control switch fitted as standard; ECO PRO mode with coasting function and Proactive Driving Assistant. The standard Driving Dynamics Control switch allows drivers to choose between ECO PRO, COMFORT, SPORT and SPORT+ driving modes. ECO PRO mode supports relaxed, fuel-efficient driving with features such as a coasting function. This function decouples the engine from the rest of the drivetrain when the accelerator is released at speeds between 50 and 160 km/h (approx. 30–100 mph). Vehicles with the Navigation system also include a Proactive Driving Assistant function, which tells the driver when to lift off the throttle ahead of features such as corners, turn-offs, roundabouts and speed limits. Standard-specification BMW EfficientDynamics technology includes Brake Energy Regeneration, on-demand operation of ancillary units, Electric Power Steering, Optimum Gearshift Indicator (manual transmission) and the Auto Start Stop function, which is included with either a manual or an automatic transmission. Chassis: precise tuning and wide range of optional systems for enhanced sporty performance and comfort. The driving experience in the BMW 2 Series Convertible is defined by an outstanding balance between sporty performance and comfort, courtesy of highly advanced, precision- tuned chassis technology, which includes a double-pivot front suspension with spring struts and anti-roll bars as well as a five-link rear suspension, an electrically assisted rack-and- pinion steering system and a high-performance braking system. With its low-weight components, the increase in track width and wheelbase compared with the previous model, the rear-wheel-drive set-up, the low center of gravity and the balanced load distribution between the front and rear axles, the BMW 2 Series Convertible chassis is ideally equipped to offer confident agility, precise handling and superior driving comfort. Standard Dynamic Stability Control (DSC) includes functions such as the Anti-lock Braking System (ABS), Dynamic Traction Control (DTC), Cornering Brake Control (CBC) and Dynamic Brake Control (DBC). These systems are complemented by Brake Assist, Fading Compensation, the Brake Drying function, the Start-Off Assistant and the Limited Slip Differental emulating Active Differential Brake (ADB-Sport) on the rear axle, which is active even in DSC-Off mode. The BMW 228i Convertible is equipped with standard 17-inch alloy wheels. 18-inch alloy wheels are available as optional equipment, while the accessories range includes 19-inch forged BMW M Performance alloy wheels. The available Track Handling Package includes a range of chassis systems including variable sport steering, which features a variable-ratio steering rack that becomes more direct as the steering angle increases, for example when parking or making a turn. Included in this package is the M Sport brake system featuring four-piston fixed calipers at the front, two-piston fixed calipers at the rear and extra-large brake discs. The calipers are painted dark blue and carry the M logo. The M Sport brakes require 18" light alloy wheels with Michelin Pilot Super Sport tires non-run-flat performance tires. Also included is the Adaptive M suspension with electronically controlled dampers with a 10- millimeter reduction in ride height compare to the standard suspension set-up. The BMW M235i Convertible: The first open-top M Performance Automobile Following the BMW M235i Coupe, the M235i Convertible becomes the first open-top M Performance Automobile, offering the characteristic M brand of exhilarating driving enjoyment. Like the coupe, it features a higher-output M Performance TwinPower Turbo inline six, mated to either an 8-speed sport automatic or six-speed manual transmission. Aerodynamically optimized body features and custom chassis components are matched with typical M precision to the engine performance characteristics, ensuring a perfect blend of outstanding agility and precise handle. The BMW M235i Convertible amps up the passion and adrenaline of dynamic open-top driving to new heights. Like its BMW M235i Coupe stablemate, the open four-seater also has a distinctive and authentic character rooted in the experience of BMW M GmbH as a developer of high-performance sports cars for general everyday use. Drawing on this exclusive know-how, the BMW M235i Convertible provides the perfect balance of engine power, chassis engineering and aerodynamic characteristics to deliver levels of agility, precision and emotional intensity that are unsurpassed in the premium compact segment. Inline-six engine with M Performance TwinPower Turbo technology. The M Performance TwinPower Turbo inline-six in the M235i Convertible offers an infectious blend of responsive power, high revving ability and powerful torque that remains constant over a wide engine speed range. Highlights also include its highly efficient design, which gives the BMW M235i Convertible fuel economy figures that are all the more remarkable in the light of its performance. The M Performance TwinPower Turbo technology comprises a twin-scroll turbocharging system, High Precision Direct Injection featuring centrally positioned multi-hole injectors, VALVETRONIC variable valve lift regulation and Double-VANOS variable camshaft timing. A cooling system, engine management and engine sound tuning, all of which have been exclusively customized to the requirements of the BMW 2 Series M Performance models, complete the picture. Maximum power of 320 hp is generated between 5,800 and 6,000 rpm, from a displacement of 3.0 liters. The maximum torque of 330 lb-ft is available between 1,400 and 4,500 rpm. With the standard eight-speed Steptronic sport transmission with Launch Control function, the BMW M235i Convertible accelerates from 0-60 mph in 4.8 seconds. It is also available with a six-speed manual gearbox with dry sump lubrication. Its short-throw action provides extra-sporty shifting. 60 mph is reached from a standstill in five seconds flat. Top speed is electronically limited to 250 km/h (155 mph). In line with contemporary concerns, the BMW M Performance models incorporate an extensive range of BMW EfficientDynamics technologies. US EPA numbers are not yet available for the M235i Convertible, however the M235i Coupe boosts a near 20 percent improvement over its 135i Coupe predecessor. Agile and precise custom chassis technology. Thanks to typical precision-tuned M custom chassis technology, in the BMW M235i Convertible outstanding engine performance is translated into assured driving dynamics. Custom-configured suspension and damping systems as well as special front suspension elastokinematics are adapted both to the performance characteristics of the six-cylinder engine and to the specific requirements of the open body style. The M Sport brakes and variable sport steering – the latter again specially configured – are standard specification on the BMW M235i Convertible. Also standard are exclusive 18-inch M alloy wheels with mixed Michelin Pilot Super Sport non-run-flat performance tires in size 225/40 R18 front and 245/35 R18 rear. These specially developed high-grip tires optimally transmit all dynamic drive forces to the road. Optimized aerodynamic balance, sports car flavor in the cockpit. The precisely controllable handling of the BMW M235i Convertible is partly down to custom chassis technology but partly also to an optimized aerodynamic balance. Aerodynamically styled body parts, which include an M-style front apron, are a hallmark of the BMW M235i Convertible's design. The large air intakes in this apron, with flaps adapted from racing car design, extend into the area which on the other versions of the BMW 2 Series Convertible is reserved for the fog lamps. The exterior mirror caps are finished in Ferric Grey metallic. Further exterior design features include the striking side sill contouring and a rear apron whose lower section, in Shadowline metallic, also incorporates the twin tailpipes in black chrome. Further exclusive design features include door sill finishers with aluminum inserts bearing "M235i" lettering and a specially "tuned" interior that features sports seats for the driver and front passenger, an M leather steering wheel with multifunction buttons, Aluminum Hexagon interior trim with accent strips in matt Estoril Blue or high-gloss black, leather trim for the gearshift lever/selector lever and handbrake lever gaiter, and an M driver's footrest. The custom instrument cluster features red markings and numbers for the speedometer and tachometer, while the instrument cluster with extended features additionally has a digitally produced model designation. Rounding off the interior specifications of the BMW M235i Convertible are variable-color interior lighting and blue detailing for the car key. BMW ConnectedDrive in the BMW 2 Series Convertible: Debut of over-the-air updates to navigation data Intelligent connectivity between driver, vehicle and outside world is another area in which the BMW 2 Series Convertible affirms its benchmark position in this class along with its advances over the previous model. The wide range of standard and optional driver assistance systems and mobility services from BMW ConnectedDrive – designed to optimize comfort, safety and the infotainment experience – is unique in the subcompact segment. On top of this, the 2 Series Convertible is the first BMW model to offer free-of- charge over-the-air updating of navigation data via the embedded SIM card, when equipped with the available BMW Navigation System. In another first for the BMW 2 Series Convertible, this standard SIM card is capable of supporting the LTE wireless standard, enabling fast and reliable data transfer. This system regularly updates its navigation data several times a year, whenever a new map version becomes available. There are no license fees or data transfer charges for the user during the first three years. The new home region map data is relayed to the vehicle wirelessly via the built-in SIM card, so there is no need for manual installation from external data storage devices. The update is installed conveniently and completely automatically, with progress being shown in the Control Display. Regular updating means there is never any delay before users are able to use the latest map software – and continue enjoying a perfect navigation experience. What's more, all navigation features remain fully functional during the updating process. To support further improved data transfer for this and other BMW ConnectedDrive functions – such as the Navigation system's Advanced Real Time Traffic Information (ARTTI) feature – the BMW 2 Series Convertible's built-in SIM card supports the LTE wireless standard. The new high-speed internet technology provides much faster data transfer rates. Internet-based services can be integrated into the car via apps. The basis for this new dimension in intelligent connectivity is the optional Technology Package, which gives customers access to remote functions, BMW Online portal and Advanced Real-Time Traffic Information. The BMW Assist eCall with Enhanced Automatic Collision Notification function and BMW TeleServices, meanwhile, are standard specification on the BMW 2 Series Convertible. Many other functions can be added at any time using apps – either via a smartphone integrated with the vehicle using special interface technology or via the built-in SIM card. These include web radio functions and social media services such as Facebook and Twitter. This flexible apps strategy makes it possible to incorporate not just proprietary BMW Group apps but also BMW Apps-ready applications from other providers. This will allow BMW drivers to seamlessly transfer a host of functions they already use at home to their car. Enhanced convenience, safety and driving enjoyment with innovative driver assistance systems. The range of BMW ConnectedDrive driver assistance systems available for the BMW 2 Series Convertible offers unrivalled variety. Among its numerous features is a standard rain sensor with automatic headlight activation. If the optional Xenon headlights are specified, the vehicle is also equipped with Adaptive Headlights including cornering light, variable headlight distribution and adaptive headlight range control for city and highway driving. Customers can also order their car with the optional High Beam Assistant. Precise and convenient maneuvering is facilitated by Park Distance Control and the rear view camera (both included in the Driver Assistance Package), which displays its images on the iDrive operating system's Control Display. The likewise optional Parking Assistant assists the driver in selecting and maneuvering into parallel parking spaces. BMW 2 Series Convertible can also be specified with the innovative Active Driving Assistant feature as part of the Driver Assistance Plus package, which also includes Speed Limit Info. This system includes the camera-based systems Lane Departure Warning and Forward Collision Warning as well as the Attention Assistant. Lane Departure Warning can be used at speeds over 37 mph and alerts drivers by means of a visual signal in the instrument cluster and a vibration of the steering wheel if they inadvertently drift out of their lane. At speeds upwards of 10 mph (approx. 15 km/h), Collision Warning detects if the vehicle is getting too close to traffic in front. In this case, as well as providing visual and audible warnings, the system also primes the brakes in order to minimize the braking distance the moment the driver intervenes. The all new 2015 BMW 2 Series Convertible will make its North American debut at the 2014 Los Angeles International Auto Show and arrive in US showrooms in early 2015.

    The Active Autowerke Prima supercharger kits for the E46 M3 are an exceptional value for one looking to add forced induction to their S54 motor. Tuning Tech FS has spent quite a bit of time tuning the various Prima kits. Their Prima Dynojet results showed 426 horsepower at the wheels on 5.8 psi of boost. Going to the upgraded Prima Plus kit with methanol injection and 9 psi raises output to 514 horsepower at the wheels on a Dynojet. Now, Active is adding a Prima Elite supercharger kit to the range. The pricing and details are not yet finalized but Tuning Tech FS is already tuning the setup. The Prima Elite and Prima Plus both run 9 psi of boost but the Prima Elite is running E85 fuel instead of 93 octane and meth. The Prima Elite on E85 manages another 31.7 peak wheel horsepower over the Prima Plus with torque gains through the curve. We're waiting on further details as the R&D process is wrapped up but these are solid gains over what already is a solid supercharger kit:

    Interesting comparison here between the current C7 RS7 featuring the 4.0 TFSI twin turbo V8 and the C6 RS6 which uses a 5.0 liter twin turbo V10. As AudiBoost published in an article last year dyno results show that despite the extra two cylinders and liter of displacement for the C6 RS6 the C7 RS6's 4.0 TFSI actually shows more torque and the power output is a wash. How do the two motors stack up in the real world against each other when tuned? Well, the C7 RS7 makes surprisingly easy work of the RS6 and the 5.0 liter V10 the 4.0 TFSI V8 replaced. There are two runs from a roll in the video below and the newer car pulls easily in each run. Pretty impressive considering both cars feature tunes with the C7 RS7 running an APR tune while the C6 RS6 has a Sportmile Stage 2 tune. The RS6 is the avant model and the lighter sedan would likely do better against the RS7. It would still lose though as by 160 miles per hour the RS7 puts bus lengths on the RS6. Many Audi fans complained about the loss of the 5.0 liter tin turo V10 for the RS6. The 4.0 TFSI V8 clearly is more than up to the task of replacing it.

    Interesting matchup here of new-school hybrid sports car technology against the more traditional sports car without electronic assistance. The BMW i8 is not a slouch despite its 1.5 liter three-cylinder turbo motor. The i8 manages an impressive 0-60 in 3.8 seconds. It also gets through the 1/4 mile in 12.3 seconds at 114 miles per hour. Solid performance for the 357 horsepower and 420 pound-feet of torque hybrid car. Is that enough to out drag a Porsche 991 Carrera S though? The Carrera S gets its power from a 400 horsepower 3.8 liter flat-6 engine. That is the standard Carrera S but this 991 Carrera S is equipped with the $17,800 X51 Powerkit which adds 30 horsepower courtesy of new cams, cylinder heads, and a new tune. On paper the Carrera S should have the advantage considering it has more power and its 3332 pound curb weight is just slightly lighter than the 3380 of the i8. The main area of advantage the i8 has is that the electric torque comes on instantly off the line and with its all wheel drive that should on paper allow the i8 to get a lead from a stop courtesy of the 100 lb-ft torque advantage. The Carrera S should then catch and pass it. How does it play out in practice? It's an easy beatdown. Considering the standard 991 Carrera S is already quicker and faster than the i8 the Powerkit just makes the gap larger. The i8 is an awesome technological achievement but it is not a replacement for the Porsche 911 or the traditional sports car. At least not yet.

    Very nice numbers here from a Porsche 997.1 Turbo running the Tial Alpha A3076 turbo based Boost Logic BL1000 kit. In addition to the BL1000 kit this 997.1 Turbo also has a full GMG exhaust. Tony over at EPL (European Performance Labs) which is located in Stratford, Connecticut was tasked with tuning the setup. The result is a very healthy 896 horsepower and 735 lb-ft of torque at the wheels on a Dynojet in SAE correction. Keep in mind this vehicle is tuned on the OEM DME. Many of the high horsepower 911 Turbos are going standalone but it is very impressive to see this output with factory computer. EPL clearly knows what they are doing and the curve is nice although the amount of smoothing on the graph is not shown. PorscheBoost is wondering if that is because the torque graph gets a little jagged going up and down at point. Regardless, this is impressive output on MS109 fuel with the turbos pushing 29 psi on the stock motor. This much torque will bend the factory rods sooner rather than later so this is not a setup for daily use but essentially kill mode (or kill the rods mode). A motor build is definitely recommended but one can definitely make 900 whp on the stock 997.1 Turbo motor if that is what they desire.

    Last month German publication Sport Auto compared a 1992 E30 M3 DTM car to the F80 M3 on the Hockenheim and the E30 DTM car crushed it. This led to F80 M3 fanboys stating the comparison was not fair because the E30 M3 DTM car is a race car and the F80 M3 is a street car. Apparently a three decade old design with a naturally aspirated four banger beating up on the pride of the modern M division ruffled some feathers. Well, here is a comparison with an E30 M3 that is much closer to the street car. The 1987 FIA Group A car is less powerful than the E30 DTM car and even closer to the E30 M3 street car. Additionally, Mid-Ohio is a larger race track than the tighter Hockenheim that gives an edge to power meaning the straightaways favor much more powerful F80 M3. Before we get into which car excels where on this racetrack we want to highlight the difference in powertrains here. The E30 M3 has a four-cylinder which was developed specifically for FIA and DTM racing. The four-cylinder offered higher revs than BMW's inline-6's at the time and sitting further back in the chassis it offered better balance. The S14 as it is fondly remembered was developed by the same man responsible for BMW's insane 1500+ horsepower turbo four cylinder engine era: "The engine was a highlight. Although there was an internal push to use one of BMW's signature inline-sixes, M technical director Paul Rosche, the mad genius behind BMW's 1400-hp, four-cylinder Formula 1 engines, wanted the balance and high-rpm stability of a twin-cam four. To make the first prototype, he literally sawed two cylinders from the head of an M88—the 24-valve six from the M1 supercar—and paired it with a version of the iron block used in the 2002tii. (Fun facts: The F1 project started with that same block, and Rosche was later responsible for the McLaren F1's V-12.) Test engines vibrated themselves to pieces but produced around 200 hp and more than 7000 rpm." So in the F80 M3 you have modern BMW M power with forced air providing close to 500 horses and in the 1987 E30 M3 Group A car you have an S14 four-cylinder spinning to around ~8000 rpm with roughly 320 horses. The later DTM cars had more displacement and revved to roughly ~10000 rpm with 340+ horsepower. The DTM car obviously offers a bit more power, torque, and tighter gearing. The weight difference between the two cars is about 1400 pounds which is night and day. So how does this play out? The F80 M3 dominates the straights and the E30 M3 dominates the twisties. The end result is practically a wash with the F80 M3 coming ahead by three tenths thanks to its shift speed and straightaway advantage. The comparison plays out exactly as it should. The new car is more powerful and technologically advanced but the track oriented E30 M3 is still more than a match on the roadcourse. Very different M cars but it is certainly interesting to see the past and present compared: Source
