    CARB (California Air Resources Board) is doing its darndest to ruin performance cars for everyone. What is the problem? CARB is adopting standards for 2025 that automakers believe are far too strict. Why is this a problem? First of all, automakers already stated they simply can not meet the previously proposed standards. Secondly, the rest of the states in the union would be forced to acknowledge CARB's decision. That means even if you do not live in California CARB would still be able to push your state around. Imagine for a moment a new car coming out with a lot of horsepower that is very efficient and meets EPA standards but does not meet CARB standards. Effectively, there would be two sets of emission standards in the USA but the CARB standards could force that automaker to abandon selling the car in the United States or even worse not bother producing it. Want to know what is truly troubling? Arizona, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and the District of Columbia all decided to agree to CARB's standards. That means many of you are not exempt from California's eco-nazis even if you do not live in California. CARB gets away with setting federal standards as it pre-dates the EPA and a waiver under the Federal Clean Air Act means their emission standards must be recognized by other states. What will happen? Who knows. The Trump administration froze EPA grants to CARB hitting them where it hurts. The Trump administration also cut funding to the EPA. The Obama administration on their way out rushed approval of new EPA standards that align with CARB prior to Trump taking office. CARB blames the automakers: The White House believes California is going too far: As you can see, this is all pretty messy and will involve a lot of lawyers on taxpayer dime to sort out. The best case scenario is that CARB's waiver is revoked effectively neutralizing their power. The worst case scenario is two standards floating around which carmakers simply decide not to even bother with and stop producing performance cars altogether for the US market. Thanks a lot California.

    Here it is, the Weistec W.4 AMG M157 5.5 liter V8 turbocharger upgrade package. BenzBoost showed teasers previously of the turbo hardware and a preliminary dynograph. Well, the production kit shows 856 horsepower and 759 lb-ft of torque at the wheels. That is at all four wheels on a 2016 W212 E63 AMG S. Additionally, with 91 octane pump fuel at 20 psi with supplemental methanol injection. The car also has the Weistec 722.9 Bulletproof transmission upgrade: That is a ton of power and torque and keep in mind this is not with the turbochargers turned up as this M157 is stock internally. There will be a W.5 package with forged internals which of course have been available from Weistec since last year. What will this turbo upgrade do with a built M157 and the turbos cranked up? Well, we will soon find out but expecting 1000+ is within reason. As for performance the W.4 was measured at 60-130 in 6.153 seconds: We will have to wait and see on the 1/4 mile times. Overall, Weistec has done a ton of testing on the W.4 upgrade and you can rest assured that it delivers as advertised: http://weistec.com/m157-w-4-package.html M157 W.4 Package The M157 W.4 package is the package for customers seeking the pinnacle of performance and refinement. At the core of the M157 W.4 Package is the M157 W.4 Turbo Upgrade. Taking a giant leap ahead of all other available upgrades, the M157 W.4 Turbochargers completely replace the factory units. They are ball bearing, featuring CNC machined billet aluminum compressor wheels capable of flowing 65lb/min. To feed these monster turbochargers, completely new airboxes and intake tubes are included. The Weistec Turbo-Folds provide significantly increased flow of exhaust gasses compared to the stock turbo-fold. The Weistec M157 True Downpipes perfectly mate up to the M157 W.4 Turbochargers to ensure minimal restriction once the exhaust gasses have gone through the turbine. An Engineered Solution The W.4 Turbochargers are the most capable production turbochargers available for the M157 engine. The W.4 Turbocharger Package which includes our M157 ASV/Water-Methanol Injection System is capable of producing 1000+ crank horsepower (820~850HP at the wheels on a Dynojet Dyno) on 91 octane pump gas. What’s equally impressive is that these numbers are achieved at only 20psi, and 20 psi is only the beginning. The goal of the W.4 Turbocharger Package was to have a complete package that provides amazing gains in power and performance, but does not require race gas, or an iced down intercooler system. Something that can be daily driven, filled up at any gas station, and is within power capacity of the factory engine internals. Control = Reliability While the M157 engine is a very robust engine in factory form, we have seen a couple weak leaks at extreme power levels. The most common is a bent connecting rod. If the engine is producing a sustained 1000 lb-ft of torque (820-850 lb-ft at the wheels) or more, all it takes is one knock event to bend a rod. This was taken into consideration with the ECU tuning for the W.4 Power Package as they can make far more power and torque than a stock M157 engine can handle. Boost is controlled and tapered up to the peak of 20psi as RPM’s increase. This creates a broad torque curve that remains under 800 lb-ft (at the wheels) while allowing power to continually increase towards redline, minimizing stress on the rods as well as the rest of the drivetrain. With a fully built M157 and other supporting upgrades, expect to see significantly higher power numbers as the Turbochargers can flow enough air volume for 1400+ crank horsepower! Key Features: Ball Bearing Turbochargers Removed Restriction of Stock Turbo-Folds Weistec M157 Airboxes with Turbo Intake Tubes Greatly Increased HP and Torque Improved Throttle Response Eliminated Top Speed Limiter Optimized Fuel, Spark and Boost CNC Billet Aluminum Compressor Wheel Upgrade 65lb/min Compressor Flow Improved Airflow Aggressive Exhaust Note Free Flowing Exhaust 1000+HP Capable

    "Ask any racer. Any real racer. It don't matter if you win by an inch or a mile. Winning's winning." Everyone remembers that quote from the first Fast and the Furious movie. You know, the movie that was about street racing and the scene that surrounded it? Well, something happened to the franchise. It shifted focus from car racing to action scenes. This was good for the box office but there is little remaining for car enthusiasts. The reason the Fast and the Furious originally appealed is that chase scenes, races, and awesome cars were the focus. The vehicle action scenes almost seem forced in the later movies. Bloomberg posted an excellent piece detailing how things changes. Let's just take a look at a few of their data points: You can read the full (and very well done) article here: https://www.bloomberg.com/graphics/2017-fast-and-furious/ At least there is room for a new movie or even franchise that is more centered around cars as the Fast and the Furious moved toward big budget action scenes and Hollywood starpower.

    This is glorious and well deserved. Remember when Pure Turbos released their excellent M177 turbo upgrade for the W205 C63 platform and an idiot by the name of @1fastc63s started running his mouth about how the dyno numbers are fake, Dime's turbo upgrade is better, and proceeded to challenge everyone on Instagram to race in order to prove it? Well, he got his wish. Oh boy did he get his wish. Let's start with a DME Tuning tuned C218 CLS63 M157 with two passengers pulling the Dime turbo upgraded W205 C63 S M177: Well, that did not work out as planned, did it? Now to truly highlight the insecurity and immaturity of this kid with the C63 S, here he is getting pulled by an F82 M4 on the factory S55 turbochargers and a DME Tuning ECU flash tune. The beatdown is so bad he tilts the camera down and refuses to provide the rest of the footage: He mad? He mad: Way to go winner!

    This S14 was fully drag prepped with slicks, and looked pretty fast, he was on it hard, not sure if this was just a shake down, he was limited by traction or gearing, but this is not even fair... One of the three 172 passes on the day...:naughty:

    Well, at least that is what the guy would have you believe. Sorry for the poor photo but I was driving and it was hard to get a shot with my cell phone while keeping pace as he tried to pull away: M5 badge on a 535i or 540i. Traffic opens up and I easily blow by him without trying. We get a light and I roll down the window and tell him that he wishes that was a real M5. He laughs and nods then tells me he has an i8 and an M550i on order. Young guy with a fake M5 so I don't buy it but whatever. I give him the hit off the line and destroy him by bus lengths. Seeing the fake M5 just brought up something in me that I had to expose it. I might not have been in the M but I still feel the need to call people on this kind of BS.

    I knew it would happen sooner or later. Way too many Teslas in my area and I wanted to be modded before hitting a stoplight with one but no such luck. Fortunately, it was a Model X P90D. I blew by him and then hit a light and he pulled up next to me so we both knew it was on. I did a soft launch launch and he didn't get me off the line. With the way these things are hyped I figured I would have to run him down. Don't get me wrong, that big boat hung in there well until I was was deep into third and which point I probably had 5 cars or so on him and was continuing to pull. Yes, I know the Model X is slower. However, these things are hardly unbeatable. I'll definitely want a tune if I run into a Model X P100D and especially if I run into a sedan.

    Talk about some pretty impressive hardware! Evolve took their tuned F10 M5 to Vmax event which is essentially top end racing. Their ECU tuned F10 M5 did not shy away from some stout competition and it did incredibly well. C7 Audi RS6. The all wheel drive wagon gets the F10 M5 as it just goes WOT off the line but the M5 runs it down and passes easily. Just a much stronger top end pull: Next up is a tuned W205 C63 AMG S. The C63 just is outclassed: Now we get to the good stuff. How about a Pagani Huayra? The odds of ever seeing one are slim let alone getting a run with one. The Huayra features a 700 horsepower AMG M158 twin turbo V12. Yes, it can be tuned although this seems to be a stock example. It is blistering fast in stock form and only weighs 3064 pounds. The M5 and the Huayra are door to door but then the Pagani starts to edge at higher speeds. The BMW sedan really hangs in there well against an incredible exotic: Next up is a Lamborghini Huracan. It just does not have the top end pull to compete: Finally, a Porsche 991 Turbo S. The Porsche just rockets off the line and has a huge lead. The M5 has to run it down but begins to close the gap. It actually manages to catch up and pass. An event like this where the M5 can really stretch its legs is well suited to its strengths.

    This is impressive considering the competition is a blown 6.2 liter Corvette LT4 V8 which runs over 130 miles per hour in the 1/4 mile stock. This is of course a longer 1/2 mile race which favors the car with more power. That car happens to be the F82 M4. Fuel-It! has their S55 port fuel injection system on the car as well as Pure Turbos Stage 2 S55 turbocharger upgrade. The car also has a BMS JB4, BMS intake, BMS charge pipes, and an ACF exhaust. The Z06 belongs to BMS and is an automatic with E30, a tune, intake, and 2.3 upper pulley. The run is recorded through the Corvette Performance Data Recorder which unfortunately only offers one camera angle but that angle is enough to show the M4 pull away easily.

    This race comes after a race from earlier this month that also featured the BMW F80 M3 Competition Package and Giulia Quadrifoglio except with the W205 C63 AMG S taking the place of the ATS-V. Well, as the C63 was the slowest of the trio anyway the American contender in the segment makes for a good replacement. As a reminder, the ATS-V and its LF4 3.6 liter twin turbo V6 is rated at 464 horsepower and 445 lb-ft of torque. As crank output in this group does not tell the whole story the ATS-V puts down about 438 rear wheel horsepower and 431 lb-ft of torque at the wheels on a Dynojet stock. Unfortunately, that isn't enough. The ATS-V gets smoked exactly as it should. It is the heaviest car of the trio. It traps roughly 114 miles per hour in the 1/4 mile so ignore the Cadillac test ringers. What you see here is a real world representation and the ATS-V is just overmatched. The M3 and the Quadrifoglio again are close with the Alfa Romeo edging. What about the trap speeds? The French at Motorsport Magazine don't know what those are.

    GAD Motors does some really incredible builds and Mercedes-AMG work. Recently they swapped a built 5.8 liter M157 into an E-Class coupe effectively creating the monster E63 AMG Coupe Mercedes did not. Not much is beyond their ability so no reason to doubt them here although there are many questions. Unfortunately, getting answers from GAD Motors in Germany is difficult not only due to the language barrier but also because they do not have a strong internet presence. At least they do not in the USA. The dyno clearly shows 922 horsepower and 775 lb-ft of torque: Monster power and ahead of anything any other tuner has shown despite the numbers being at the crank and not at the wheels. How are they keeping the transmission together? How are they fueling it? What is the M178 fuel system limit? If they are upgrading the dual clutch transmission who is providing the parts and what are their capabilities? Also, what does all of this cost? Unfortunately, answers to these questions are not easy to come by.

    Finally, a real world straightline comparison of these three cars going at it at the same time. Awesome right? Well, not exactly. Unfortunately Carwow who put this together does not really understand how to properly do this. Many automotive journalists do not so we are not singling them out but right off the bat there is a massive flaw. It is called traction dependent results. What this means is the result will be different based on who gets the best launch. The Alfa Romeo gets the best launch and wins the drag race with an 11.9 second pass. The F80 M3 trails it at 12.3 seconds with the Mercedes-AMG C63 S bringing up the rear at 12.6 seconds. Where are the trap speeds? Why were they not recorded? We would easily be able to tell which car is the fastest and which is simply traction limited with that data. Why is this constantly omitted by so many so-called journalists in so many so-called tests? What is so hard to understand? Consider for a moment if the C63 S is outfitted with drag rubber. Does it suddenly become the fastest car there? The same goes for the M3. With proper rubber is it suddenly the fastest car? All this drag race shows the viewer is that the Alfa got the best launch which can vary greatly on street rubber and based on driver input. If Carwow is not interested in properly displaying what the cars are capable of in the 1/4 mile then they should include trap speed data or run them from a roll where the traction variable is mitigated. That way this would actually be a useful comparison. Fortunately, they do run them from a roll so this is not a total disaster. The Alfa Romeo pulls all three cars although the Mercedes-AMG looks to get a poor start. It certainly lends credence to the Alfa Romeo's tested 119.8 1/4 mile trap speed. Overall, the Alfa Romeo Giulia Quadrifoglio is a very strong entry in the segment and that is a wonderful thing.

    Vendors go about their online business in different ways. Some choose to stay out of it and just let their products do the talking. Others are very loud and constantly involved in social media and forum flame wars touting their product as the best. Often times those who yell the loudest are the most desperate for attention. Take Dime Racing as an example. Yes, the same Dime Racing that Weistec took to court. That matter has since been settled with undisclosed terms but Dime Racing continues to engage in some very shady behavior online. Last year Dime was caught trying to take credit for what was actually Weistec's performance on social media. Before that they used a Weistec dynograph claiming it was their own. Now they are going after Pure Turbos. Why? Because Pure Turbos entered the M177/M178 turbo upgrade market and is showing great results for less money. AMG modding is where Dime operates and a new competitor offering a better product for less money must be destroyed online rather than beaten through honest competition. The trolls were let loose: Pathetic, right? First they claim the Dynojet numbers are manipulated and a fabrication. Clearly someone needs to read the recent BoostAddict article on Dynojets vs. Mustang dynamometers. Secondly, they say Pure Turbos should 'prove it' and race them. Yes, seriously, they ask Pure Turbos to race a customer car without permission for some stupid internet grudge match. Pure Turbos being a responsible and professional company laughs this off and then the troll claims they backed out. Unbelievable. This goes on further where the Dime trolls imply this turbo upgrade will blow your motor. You get an idea of the pattern. The whole reason for this weak trolling attempt is to try to discredit a new option that is showing very well for less money. Pure Turbos is to be commended and let's just say we are all glad they do not race internet trolls in customer cars but instead let the performance numbers do the talking. This type of thing happens more often than you think. In the past, a tuner who took a similar approach was MHP and the owner actually asked BenzBoost to create troll accounts so the owner could go on a certain forum and try to undermine the competition. BenzBoost declined and MHP is now history. This same sort of thing is going on today with Dime having troll accounts on certain forums that specifically attack competitors. We know of a certain tuner that is sick of it and you can probably add Pure Turbos to that list. Maybe Dime Racing has an M177 turbo upgrade that works now (Eurocharged dumped them due to issues). Maybe their tuner isn't committing felonies any longer. Maybe Rod Shegem (http://rod-shegem.com) is not stealing money. What is clear is that a black cloud and negativity seems to follow Dime Racing wherever they go.

    The BMW M3/M3 and Porsche 911 have quite a bit in common this generation. Why? Because both have twin turbocharged and direct injected 3.0 liter six-cylinder powerplants. You can also get either with a dual clutch or manual transmission with power sent to the rear wheels. Let's look over the specifications of the motors: 9A2 3.0 991.2 Carrera Horsepower: 370 Torque: 332 lb-ft Boost Pressure: 13.1 psi Bore x Stroke: 91mm x 76.4mm Redline: 7500 rpm Compression Ratio: 10.0:1 Intercooler: Air to Air Turbos: 49mm compressor/45mm turbine Piston Speed FPM: 3759.842 BMW S55 Horsepower: 425 Torque: 406 lb-ft Boost Pressure: 18.1 psi Bore x Stroke: 84.0mm x 89.6mm Redline: 7500 rpm Compression Ratio: 10.2:1 Intercooler: Water to Air Turbos: 51mm compressor/43mm turbine Piston Speed FPM: 4409.449 Obviously, we all know the S55 engine is highly underrated by BMW. Recently, when Porscheboost was doing some testing at VF-Engineering on their Mustang dyno the opportunity presented itself to overlay a stock S55 with the stock PorscheBoost project 991.2. Here is the result, both dual clutch examples stock on 91 octane pump fuel: What is interesting to note is that the spool on the 991.2 Carrera 9A2 is much better than the BMW S55. The Carrera is spooled by 2400 rpm and the S55 has more lag by roughly 1000 rpm. That is significant. You will notice once spooled the curves are fairly similar. The S55 does have more peak torque and horsepower but the difference is not as large as one would expect. The difference in torque is only 3 lb-ft at the wheels. A wash. Not bad for what on paper is supposed to be 74 lb-ft. The 911 is making more torque than Porsche is letting on by quite a bit. The difference in peak horsepower is 15 at the wheels. This is attributed to the S55 making power to 6850 rpm while the 9A2 is tailing off past 6400 rpm. Both torque curves are dropping hard but the S55 maintains a top end edge from 6400-6800 rpm. Revving either engine out to their 7500 rpm redline does not gain anything and short shifting is preferred for maximum performance. It is interesting that the 9A2 engine with less boost and slightly lower compression is so close. It is also interesting the spool is so much better but Porsche likely concentrated very hard on quick spool down low to appease naturally aspirated purists who would complain about lag. The engine comes on strongly and quickly. It is no wonder the 9A2 knocked out the S55 in its category at the 2016 International Engine of the Year Awards. In an ideal world we would be able to toss a Carrera S and a GTS onto this dyno to see how Porsche is really separating their 9A2 motors. We do have Dynojet numbers posted for the Carrera and S but the GTS is the variant we are all eagerly awaiting to see. This is the difference between the turbocharged 991.2 Carrera S 3.0 and the naturally aspirated 991.1 Carrera 3.4: BMW of course has the Competition Package version of the S55 and now the CS version in an even higher state of tune essentially doing what Porsche does in offering the same motor in different flavors. The main difference though is that Porsche changes the turbochargers and not just the software offering greater differentiation and tuning value in this respect. What is clear is that the turbo era is elevating power and torque to heights we have never seen and it will result in a far greater proliferation of tuning for Porsche and BMW models than ever before.
