    This is certainly an interesting development and our users will agree that the more aftermarket options they have the better. Evolution of Speed, who we have never heard of previously and have no affiliation with, is set to release their N5X intake manifold which will gain a lot of interest from N54 and likely N55 owners as well. The obvious here is that guys would want to pair this with methanol injection or port injection for supplemental fuel. The expected price point and design makes that aspect attractive. This would not be something that N54 or N55 owners expecting big gains over the OEM manifold would benefit from but for more hardcore owners making big power with say a single turbo upgrade. Exactly the kind of power junkies who are on BimmerBoost. It will be interesting to see the results from members who buy this product and what the options will be such as the finishes, integrated port injection, etc.

    It is almost unbelievable what the 'tiny' stock frame turbocharger housings that BMW equipped the N54 3.0 liter direct injected inline-6 motor with are hitting these days. Just look at the size of the stock frame and it is hard to imagine capability of over 700 wheel horsepower. But that is exactly where we are in the N54 world today. VTT (Vargas Turbocharger Technologies) came deliciously close to breaking that magical 700 wheel horsepower barrier. There is more tuning to come but it's safe to say the 700 wheel horsepower barrier will be broken shortly showing capability nobody ever imagined from the N54 turbos just a few years ago. Hell, they do not even need a full horse to get there: For an N54 that is a very nice looking curve as well. Who knew things would go this far?

    Some tuners make big claims before a product is actually ready for prime time. You see it all the time on the forums and the hype builds to the point it is a runaway train. Responsible tuners temper these expectations by telling a potential customer it is not ready and some just act like it is ready to continue the illusion of product superiority. It truly is fascinating and interesting how some of these companies leverage forums to not just sell products but buy minds. The idea is controlling what people think by getting them to parrot back the same lines over and over. The danger with ESS-Tuning that a person who goes by by the name RingMeister01 found out the hard way is that they long ago bought and paid for the E9X M3 upgrade market by convincing everyone on the BMW forums they are the best based on sales volume. In turn, their fanboys outnumber the rest. This somehow has been perverted into BMW tuning superiority on every BMW platform that graces the earth. ESS-Tuning may sell a lot of superchargers (the reasons for that we will not go into here) but that does not mean they are a turbo builder. Far from it as a matter of fact. AMS found this out on their own when they dropped ESS-Tuning from their F10 M5 S63TU turbo upgrade project and ESS-Tuning was supposed to provide just the tuning there and not even the turbo hardware. AMS Performance deciding to tune on their own tells you plenty regarding ESS BMW tuning and turbo expertise. The simple fact is they don't have any and when AMS sought them out to tune they had no way to actually tune the ECU. It was BS. They source their turbo hardware from turbo builders but we do not know exactly which ones or if they are reliable. ESS-Tuning does not produce turbochargers themselves just as they do not produce superchargers themselves. They sell a complete 'kit' so to speak and this kit is what RingMeister01 thought he was getting. The problem is it was portrayed to him as ready to go and complete. Based on his experience, it was far from that. After the fact our favorite forum spinmeister Roman@ESS-Tuning stated it was not a complete product but a beta product and Mr. RingMeister01 should have known better: Clever, right? State the product is in beta and that the customer expectations are way out of proportion and he should not expect some complete product. It makes you wonder then why he was under the impression he was getting a complete product ready to go from ESS-Tuning. Is RingMeister01 just unreasonable? Perhaps he's just stupid? Or perhaps the product was misrepresented? Here is what RingMesiter01 thinks: "As if I had time for non-sense but I wouldn't want others to go through this as I did. I initially spoke to Jesse from Pure turbos on getting their kit but as he knows I didn't want to run a JB4 with boost juice to reliable make gains. I wanted a flash tune/turbo package. Jesse was very helpful in educating me on what they were offering and what to expect from their kit. I must say he is extremely knowledgeable and professional. IND working on their S63tu turbo upgrade with AMS was another option. Again this was in its early stages but I sent over a new set of turbos for them to look at for machining, etc. AMS at the time was so busy with whatever other monsters they are creating that they couldn't commit to a lead-time on developing the hardware for our cars. Ilia's plan was for AMS to upgrade the hardware and develop the tune with my turbos on IND's shop car. IMG Motorsports informs me that ESS has a kit ready to go, tune and all. He asks me to get my turbos back from AMS and send them to him for the ESS upgrade if I was interested. Like anyone else here, say ESS and its a no brainer (mainly from their success with the superchargers). The turbos are sent to IMG. I now email AJ for the upgrade details; In the email he clearly states that the kit is ready and the tune I would be getting is specific to the turbos. He also promises that they will be the best solution available. No problems at all thus far and I was really getting excited to be apart of this first kit. I offered to post a review, dyno charts and pilot runs on the forum. AJ then said "We'll give you a really good deal if you would do that for us." A few weeks pass and no word on the turbos (ecu was removed and sent within this period), so I email AJ. "Your turbos are with IMG, they were returned three weeks ago. He definitely has them." -AJ Hmm? Why wasn't I told? I send out a text message to find the turbos had arrived and that I was informed but most likely didn't receive the text from IMG because he was at Lime Rock Park and "there's no reception there, bro." Clearly that was the case as I see posts from him on Instagram all weekend from the track. Anyway... who cares, right? "AJ charged my credit card for your turbos, could you go make a cash deposit in my account for $5,000 tomorrow?" Ok now I'm a tad uncomfortable. AJ and I had spoken about pilot runs, dynos, reviews for the kit on the forum and now I'm being charged retail for the kit and I always thought I'd pay ESS directly. I ask IMG why I was being charged retail when I had already been offered a discount, "cause everything else out there is junk, bro. This is what he charged my card." Ok, I understand IMG would not be aware of my conversations with AJ, so I email AJ directly on the spot. "Your pricing is determined by the vendor, we have nothing to do with that on our end. You must go through one of our vendors." WTF. That awful feeling in my stomach comes over and I realize that this isn't going to be what I signed up for. See now Im in no control what so ever and Im at the mercy of a vendor I don't feel comfortable with and I have no choice but to pay whatever he wants me to, to get my turbos back. I emailed AJ again and bitched until IMG sent me a text "Bro, AJ refunded my card $500." Ok, lets just move forward... The ECU comes back (I must had sent 10 emails asking whether the tune was specific to these turbos and if I could please have CEL, Vmax and cold start deletes, I was assured I would. I didn't want to have the ecu removed and installed multiple times due to the process) and everything comes together at which time I get a text from IMG "car is done, get ready for 550 whp, bro" EXCITED!!! I get to the techs place (who btw is so talented and genuine). I sit in the car and say to myself (knowing how irresponsible and nonchalant this "vendor" is) I fucking bet it goes through cold start. Hit the starter button and of course, its there. I'm sure Vmax isnt deleted either. So lets just drive and see how she performs. Very smooth operation at low speed driving through a residential neighborhood, like stock. The turbos are a little loader but that is probably due to downpipes and BMC filters. I make my way to the highway and WOT. More lag and not much else. Doesn't feel fast or powerful at all. I have been in a lot of M3/4's with ecu flashes and JB4's and this just didn't impress me. I text IMG on my feed back, "Bro, put some good gas in and let it adapt. It takes 80 miles to do so. The set up is so smooth its deceiving." EEERRR....really? A day or two pass and I see this thread and comment that this kit isnt all that. I have every right to post an honest option and review, I always do and without any agenda or with any intention of hurting someone. I always valued the opinion of the members here and considered their experiences when purchasing a product. I wanted to do the same. This is when the truth unfolded. I get a message from Roman, "You aren't allowed to comment on a development project until its completed." Development project? What? Back and forth with Roman I find out that my brand new M4 with 250 miles is a guinea pig for ESS' S55 turbo upgrade. Not a fully develop system as promised but something they were trying to test out. Now I'm furious and text and email all parties. Roman says to me "IMG and Aj said you were aware of this." Motherfookers. Im texting back and forth and clearly I'm upset and Roman offers to refund me and IMG offers to remove turbos put in stock set and refresh car to stock as long as I delete all posts on this thread. I deleted what I could on the spot and emailed Jason (admin) to remove/clean up anything else. Only a few minutes turned and Roman sends me a lengthily message on how I did recieve what i payed for; upgraded ecu and turbo kit and at a significant discount... $500.. really? If I cooperate I'd get free tune upgrades and if not then ESS will sever all ties with me and stop communication. I send him a text back..."You are so fucked" I did try to suppress my disappointment and the distrust I felt and continue to just get this kit to work. IMG takes my car to the dyno and puts down what you see on the thread BUT when I asked about the dyno and a picture of the dyno, I got a half ass cell phone pic of a 1/4 of the graph and blurry to the point it was hard to make out the numbers. I asked and asked for a full picture so I could see the curves and the crossing point...ect. I just wanted to stay on top of this if I was going to use my car for development. On and on and on I get a dyno file in a format I have no idea to do with (i guess its the dynojet software) wtf am I supposed to do with that? At the end I asked about the new tune I was getting and what was different about it from the Beta file I have now. I was concerned that they were just going to crank up the boost to make numbers on the dyno. I was then insulted by IMG through texts and I just called it quits. I just don't care anymore, $4000 for new turbos, $4500 for the upgrade, $1800 for tune and priceless lies. I would had been fine with everything but just don't lie to me and twist things to make me look stupid. Judge me I don't care, I have nothing else to share here. This is for anyone as a warning- know who you are dealing with, know what you are getting into because if it goes wrong you will be left for dead." This sounds like a guy who thought he was getting a product that works. ESS stating after all of this on the forums it was a 'development project' is obviously to affect public perception of the gigantic mistake of selling a product that isn't ready. Yes, ESS never told him that and told him the exact opposite according to his own words and the e-mail records. Apparently he has the e-mails showing this and I'm sure we would all love to see them but thus far he has not published them. If it were BimmerBoost, we would and we actually have to expose deception. Hopefully ESS doesn't push him around but he seems like a guy so far that isn't responding well to ESS demands. This guy thought he would be getting turbos and a discount to post reviews, dynos, runs, etc., on the forum. A pretty standard marketing practice on forums to get supposedly 'independent' reviews. Unfortunately, a certain ESS cheerleader serving as the middle-man here decided to charge full retail. Why? To line his own pockets of course. Who cares if it works, right? Well, reputable vendors care. Nobody cared here. Get the money and oh well too bad say it's 'beta' if it doesn't work. ESS tried to keep this off the forums but it didn't work: "This is when the truth unfolded. I get a message from Roman, "You aren't allowed to comment on a development project until its completed." Development project? What? Back and forth with Roman I find out that my brand new M4 with 250 miles is a guinea pig for ESS' S55 turbo upgrade. Not a fully develop system as promised but something they were trying to test out. Now I'm furious and text and email all parties. Roman says to me "IMG and Aj said you were aware of this." Motherfookers." RingMeister01 has every reason to be angry. Not only did he not get what he paid for, not only did he pay more than he was supposed to, he is now supposed to shut up about the problems. He finally realizes he is a guinea pig. It's just that he never signed up to be one. It is somewhat interesting as well that Roman@ESS commands him not to speak. Do you see now how certain forums work now? Anything negative is kept off. If you do not shut your mouth you will not get further support. It's not about having the best products. It's about making people think that you do. That is why he was offered a refund and a return to stock if he deleted all his posts. You would think that offer would be on the table regardless as it should be instead of being conditional. This customer chose not to bend over but how many have bent over for ESS? How much has been swept under the rug? BimmerBoost is aware of much of it and some of what gets deleted is hosted here for specifically this reason. You as a potential customer deserve to know the truth, don't you? You are not a vendor's pawn, are you? Shouldn't the customers have the power in this relationship? This is the same old story with ESS-Tuning as always but trying to get it out there is the problem. They use their power to pull posts, edit threads, close threads, etc., if they are not portrayed in the best light. It's arrogance, pure and simple. What they should have done is make it a priority to fix the guys car (another tuner offered to fly out to fix it), provide what he paid for, and not charge him a dime for any of it. That would require them going out of pocket. It's simply the easier (cowardly) way out to get this all deleted, spin it, and go about business as usual. They won't be able to delete this though. If they try, the blowback will be bigger than it already is:

    Well, it certainly has been a while. Gintani announced this twin turbo kit years ago but it is finally coming to fruition. The differences between a development turbo setup and a production turbo setup are obviously night and day. It looks like Gintani finally has the kit ready for primetime. Pricing and official details have yet to be released but in the video below the twin turbo setup is being applied to an M3 and a BimmerBoost member is doing a custom stoked S65 V8 a around 4.5 liters with turbos. We will not of course hold our breath until it is done. As far as power figures those were released a while ago in a comparison against their S65 V8 supercharger setup which you can view here. The moral of that story is torque. It looks like the S65 will finally take the big step forward enthusiasts have been waiting for. <blockquote class="instagram-media" data-instgrm-captioned data-instgrm-version="4" style=" background:#FFF; border:0; border-radius:3px; box-shadow:0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width:658px; padding:0; width:99.375%; width:-webkit-calc(100% - 2px); width:calc(100% - 2px);"><div style="padding:8px;"> <div style=" background:#F8F8F8; line-height:0; margin-top:40px; padding:50% 0; text-align:center; width:100%;"> <div style=" background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACwAAAAsCAMAAAApWqozAAAAGFBMVEUiIiI9PT0eHh4gIB4hIBkcHBwcHBwcHBydr+JQAAAACHRSTlMABA4YHyQsM5jtaMwAAADfSURBVDjL7ZVBEgMhCAQBAf//42xcNbpAqakcM0ftUmFAAIBE81IqBJdS3lS6zs3bIpB9WED3YYXFPmHRfT8sgyrCP1x8uEUxLMzNWElFOYCV6mHWWwMzdPEKHlhLw7NWJqkHc4uIZphavDzA2JPzUDsBZziNae2S6owH8xPmX8G7zzgKEOPUoYHvGz1TBCxMkd3kwNVbU0gKHkx+iZILf77IofhrY1nYFnB/lQPb79drWOyJVa/DAvg9B/rLB4cC+Nqgdz/TvBbBnr6GBReqn/nRmDgaQEej7WhonozjF+Y2I/fZou/qAAAAAElFTkSuQmCC); display:block; height:44px; margin:0 auto -44px; position:relative; top:-22px; width:44px;"></div></div> <p style=" margin:8px 0 0 0; padding:0 4px;"> <a href="" style=" color:#000; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px; text-decoration:none; word-wrap:break-word;" target="_top">Lol 2 weeks took a little over a year but o well we're there!!

    The Cadillac ATS-V is impressing the automotive world with its chassis dynamics, steering feedback, and driver involvement. Areas where the BMW M3 used to set the bar and all others followed. BMW did this for well over two decades and nobody was even close. Until now that is. The Cadillac ATS-V is generating praise despite not yet winning a single comparison in which it is pitted against the BMW M3 and the Mercedes-AMG C63. The closest it has come is the recent MotorTrend comparison where the ATS-V finishes ahead of the M3 but behind the C63. So why is Road and Track proclaiming the ATS-V as a better BMW M3 than the car BMW builds? They cite the the change to the turbo powerplant: "The change to turbo power resulted in a car that had the same horsepower as before, but a torque curve like the M3 had never seen. It suddenly wasn't a car that had the joy of developing its power at the top of the range, it now had thrust everywhere. Combine that with the larger F80 platform that the new M3 rides on, and it felt distinctly more like a Bavarian muscle car than a precision instrument. It's a pretty stark change for a car that had defined its segment for decades." They get this right. The M3 and BMW's in general are now about starightline muscle more than finesse and track prowess. BimmerBoost raised many concerns about the change to turbo motors for M cars specifically as M cars are supposed to be scalpels and not sledgehammers. BMW rejected forced induction for decades in M vehicles. Why? Because they preferred response and race bred motors. Engines that could and actually did lap and win in competition without any heat soak issues. You do not employ independent throttle bodies per cylinder for fun. Combining this throttle response with high revs gave you the closest thing to a race car for the street short of a Ferrari and without their price tag and with more daily usability. BMW combined these race bred high revving naturally aspirated powerplants with the best balance in the segment (the famous BMW 50/50 motto) and the lightest curb weight. They still are the lightest in the segment but the turbo motors put some more weight on the nose so they are not quite as balanced as previously. The thing is, the ATS-V is none of the things the M3 used to be. It does not feature a high revving race bred naturally aspirated powerplant. It has a larger motor than the M3 with more torque that revs lower. If anything, it has the lazier motor. The chassis dynamics and steering response may reach or perhaps even exceed the current generation M3 but the car still is nose heavy and still weighs more than the M3. How is it a better M3? Road and Track doesn't get it. Look at this: "It has a twin-turbo V6 instead of a V8, because that allows them to keep the weight down and move the engine further back." Did anyone tell Road and Track the S65 V8 from the previous generation M3 is lighter than the ATS-V LT4 and features compact cylinder spacing specifically to be mounted as far back as possible? You know, a design for racing which is why it won back to back ALMS GT championships? Road and Track can not say in one breath that the M3's downside is its powerplant and then praise a car that features a similar powerlpant that is heavier and offers worse balance in a package not as refined. The company that is really building a better M3 than BMW is Ford. Yes, Ford. Everything the M3 used to be is what the Shelby GT350/GT350R is and then some. Ford even took a page from the Ferrari playbook and offers a flat-plane crank in the 5.2 liter V8. It is more a driver's car and track weapon than the ATS-V ever can dream of being. Do not forget the M3 was bred for racing as DTM is where E30 M3 lived. The GT350R is prepared to get more hardcore than the ATS-V or M3 for that matter with options to delete the rear seats, add a roll cage, and delete the air conditioning. The question really is how hardcore do you want to get? BMW has not built a car approaching the GT350R's level since the E46 M3 CSL and to a lesser degree the E92 M3 GTS. The GT350R of course offers high revving track thrills and higher performance with more displacement and for less money. Road and Track got this wrong. It is not Cadillac doing BMW's job. It's Ford.

    It's about time! Finally the M275 V12 has broken into the 9's. SpeeDriven is known in AMG tuning circles for their M275 V12 work which includes upgraded turbochargers. The M275 obviously is not hurting for displacement offering up to 6.0 liters in the 65 AMG models but development had stalled for a while. SpeeDriven made a lot of big claims regarding horsepower for their turbo upgrades and the most they have showed on a dyno was in the 8XX wheel horsepower range. We prefer timeslips over dynographs and the 9.975 @ 141.35 run certainly is impressive along with being a new quickest and fastest record. We expect more though. This is a 5.5 liter twin turbo V12 are talking about here with this R230 SL600 and SpeeDriven has claimed over 1000 horsepower on the platform. The trap speed of 141 is solid but there definitely is and should be more in it. Obviously people want details but the owner is keeping them quiet. Why? If he intends to do some serious street racing that is understandable. We certainly would like the details though. Obviously the car features upgraded turbos, race gas, and drag rubber. Even bigger turbos are on the way supposedly which should push this into far more serious territory. That widebody definitely isn't doing the car any favors as far as aerodynamic drag. Congratulations to SpeeDriven on breaking new ground. Now let's get some concrete details to go along with the record!

    About time Ford! Many of our readers are drooling about the new GT350 and GT350R. Who can blame them? With a 5.2 liter flat-plane crank V8 that revs out to 8250 rpm and an engine note that can make Ferrari owners turn their heads the GT350 and GT350R are going to be very popular. So what are you waiting for? Head on over to the Ford site and design your perfect GT350:

    Water injection in a direct injected turbocharged BMW inline-6 street motor? Welcome to over a decade ago BMW but nice to finally see you embrace it. As expected from earlier this year the F82 M4 GTS S55 engine features a factory water injection system which helps raise octane and keep things cooler. BimmerBoost users are likely already thinking of filling the 1.3 liter reservoir with a water-methanol blend. BMW certainly is making it easier than fitting an aftermarket system and the design is integrated with the intake manifold. The other big piece of news is that the car will be sold in the USA. Many BMW enthusiasts still have not forgiven BMW for skipping over the US market with the E46 M3 CSL and the E92 M3 GTS. Americans finally will get a real special edition M car and not the garbage BMW shoveled us previously. The M4 GTS is expected to shed some weight with extensive use of CFRP (carbon fiber reinforced plastic) such as the CFRP employed in the hood. How much of a weight drop to expect is unknown at this time. Even a hundred pounds would be greatly appreciated. Expect the car to be lighter and offer more power with a track emphasis as the aerodynamic changes show. With the factory water injection system heat soak on repeated laps should no longer be a problem. Production details will come later this year. It is nice to finally see a car aimed at hardcore American enthusiasts. BMW Concept M4 GTS to be Premiered During Monterey Car Week. The First M3/ M4 Special Production Car to be Sold in the US. Woodcliff Lake, N.J. – EMBARGO: August 13, 2015 – 9:00pm EDT/6:00pm PDT...A year on from the launch of the BMW M4 Coupe, BMW M GmbH is presenting an initial preview of a high-performance model for use on the road and on the race track: the BMW Concept M4 GTS – the first M3/M4 special production vehicle to be sold in the US. The BMW M GmbH was founded in 1972 as BMW Motorsport GmbH and caused a sensation with its iconic BMW M1 racing car. As the force behind the world's most successful racing touring car, the Group A BMW M3 and the development of the first turbocharged engine to win the Formula One World Championship, the BMW M GmbH return to its racing roots with the BMW Concept M4 GTS. The BMW Concept M4 GTS continues the tradition of BMW M3 special models already illuminated by the BMW M3 Evolution (1988), BMW M3 Sport Evolution (1990), BMW M3 GT (1995), BMW M3 CSL (2003), BMW M3 GTS (2010) and BMW M3 CRT (2011). Technology honed in race competition, a hike in power, a commitment to lightweight design and limited production numbers with unbeatable performance coupled with a powerful and exclusive driving experience. "While the BMW M4 Coupe embodies the ideal combination of motor sport genes and unrestricted everyday usability, the BMW Concept M4 GTS previews an emotionally powerful and exclusive special model conceived with an eye for trailblazing technology and a keen focus on the race track," explains Frank van Meel, Chairman of the Board of Management of BMW M GmbH. "Despite its outstanding track ability, it is still fully road-legal. This is racing technology for the road in the truest sense." The BMW Concept M4 GTS showcases new technologies which will debut in production vehicles later this year. The BMW Concept M4 GTS features the innovative water injection system that has already provided a significant output and torque boost in the BMW M4 MotoGP Safety Car. In addition, the BMW Concept M4 GTS has rear lights with OLED (organic light-emitting diode) technology for an unmistakable appearance. Optimized down to the finest detail. The BMW Concept M4 GTS builds on the BMW M4 Coupe's dynamic and emotional use of forms. Yet its character as a high-performance special model, in which every detail has been developed to fulfil its purpose as a successful track machine, also comes immediately to the fore. The manually adjustable front splitter and rear wing – both in exposed carbon – ensure perfect aerodynamic balance on the race tracks and on the road. Another example of the engineers' rigorous adherence to lightweight design is the CFRP (carbon-fiber-reinforced plastic) hood which lowers the car's weight and center of gravity. A wide front air intake optimizes airflow and minimizes front axle lift. The dynamic and exclusive presence of the BMW Concept M4 GTS is accentuated by the exterior paint shade Frozen Dark Grey metallic, with the Acid Orange accent on the front splitter creating an effective contrast. The lightweight, forged and polished light-alloy wheels in 666 M styling also feature an Acid Orange accent. The 9.5 J x 19 (front) and 10.5 J x 20 (rear) wheels are fitted with Michelin Sport Cup 2 tires (265/35 R19 at the front, 285/30 R20 at the rear). The mixed-size tires provide the ideal conduit for the stand-out dynamic attributes of the BMW Concept M4 GTS. Water injection: power up, full-load fuel consumption down. The engine powering the BMW Concept M4 GTS is equipped with the same innovative water injection system that has endowed the BMW M4 MotoGP Safety Car with a noticeable increase in output and torque. The water injection system introduced by BMW M GmbH sees the engineers using the physical effect of water when vaporizing to draw the required energy from the ambient medium. The water is injected into the plenums of the intake manifold as a fine spray. When water vaporizes and goes through its phase transition absorbs heat, cooling the air intake significantly. As a result, the final compression temperature in the combustion chamber – and therefore the engine's tendency to "knock" – is reduced, enabling the turbocharged engine to use higher boost pressure and earlier injection timing. This technology ensures an increase in output and torque, while at the same time reducing the thermal stress on performance-relevant components. All of which also enhances the stability and durability of the turbocharged engine. The BMW Concept M4 GTS brings high-performance technology directly from the race track to the road. The strong performance potential of the turbocharged six-cylinder in-line engine already demands an exceptionally sophisticated thermal management system for the engine and ancillary units. To ensure optimal operating temperatures in all situations, the M GmbH engineers have developed a highly innovative and effective cooling system. It comprises a main radiator plus additional radiators for the high- and low-temperature circuits, transmission and turbocharger in order to keep temperatures stable. The turbochargers are cooled by means of an indirect intercooler, assisted by an additional electric water pump. OLED rear lights radiate ultra-high precision. The BMW Concept M4 GTS is fitted with innovative rear lights featuring OLED (organic light-emitting diodes) technology, a new type of light source producing full-surface and homogenous illumination. Their low installation height of just 1.4 millimeters and the ability to actuate individual light modules which emit light to a single point provide flexibility and allow for precision. The world premiere of the BMW Concept M4 GTS takes place at the Pebble Beach Concours D'Elegance in Monterey, California on August 13, 2015. More details on the production version will be revealed at a later date. BMW Group in America BMW of North America, LLC has been present in the United States since 1975.

    The BMW F80 M3 is the worst of this trio? That is what MotorTrend thinks which is in stark contrast to Car and Driver who picks the M3 over the other two. Car and Driver also though the ATS-V belonged in last place whereas MotorTrend puts it in the middle and behind the comparison winner which is the new Mercedes-AMG C63 S. Here is how they stacked up: 3rd Place: BMW M3 It's cliché to say, but this is the best third-place finisher in Motor Trend history. C'est la vie. 2nd Place: Cadillac ATS-V
 This stud athlete is let down by its lack of powertrain refinement and sonic thrills. Cadillac has very little tweaking to do to get things right. 1st Place: Mercedes-Benz C63 S AMG 
 An iron fist in a velvet glove. Race mode transforms the beast into an iron fist in an iron glove. Lap times: Caddy ATS-V 1:31.43 C63 1:31.52 BMW M3 1:32.51 How the M3 finishes behind the other two on the track is a head scratcher. The M3 is a full second behind the other two? Huh? It is the lightest car with the best balance. At 3498 pounds it undercuts the ATS-V by 286 pounds and the C63 AMG S by 434 pounds. The C63 AMG S weight distribution is 54/46% front to back and the ATS-V is 52/48%. The M3 is stated to be 50/50 in this test. The ATS-V is not beating the M3 around the track based on power or being lighter. It is tested as the slowest of this trio which is in stark contrast to Car and Driver's absurdly fast numbers for the automatic ATS-V. MotorTrend previously tested the automatic ATS-V and got a 12.3 @ 114.6 out of in the 1/4 mile. Now in this comparison they get a 12.1 @ 116.2. Quicker and faster yet still nowhere near Car and Driver's ATS-V tester which now looks like a ringer. We can not make sense of the acceleration numbers for the ATS-V as they are all over the place but the M3 and C63 appear to be exactly where they should be. The C63 AMG S is shown to be the fastest of the trio yet it was the slowest in the Car and Driver test. Seriously, what the hell is going on? The acceleration numbers here at least do not look suspect as the C63 AMG S should be faster than the M3 which it is. The wild card is really the ATS-V but it is performing more like the early reports showing trap speeds in the 115 miles per hour range than the outlier of 122. A spread of over 7 miles per hour is at least a difference of 70 wheel horsepower. It is also interesting to note all three get to 100 in 8.8 seconds but the ATS-V seems to start to run out of steam above 100 miles per hour. Ok, enough about potential ringers and testing anomalies. The main thing here is the stunning last place finish for the M3. The ATS-V is said to feel sportier and the C63 AMG S is said to be the best all around package. How the lightest and best balanced car here loses and posts such a poor laptime we can not explain. The ATS-V posting the quickest laptime considering its figure eight advantage and best braking performance makes sense but the C63 beating the M3 here does not considering other track tests have shown the opposite. An interesting test to say the least.

    This is a rematch of a race from last month. In the previous race, the F80 M3 DCT came out on top on the full bolt on tuned E92 335i automatic by what looked like a couple car lengths. The E92 335i since then added the Vargas Turbo Technologies inlets and for those who wanted real proof as to their difference here it is. The cars are very evenly matched. The DCT transmission gives the F80 M3 a slight advantage down low due to the shift speed versus the 335i automatic. The 335i in the higher gears is able to mitigate the advantage and pull a bit up top. A very close race between the two. Mod list and video below: F80 M3 Mods: Eurocharged ECU flash Catless Downpipes Race gas DCT E92 335i Mods: JB4 G5 ISO with a BMS Backend Race Flash via BB App FBO VTT Inlets 100% dual nozzle meth injection 94 OCT 6AT (No Alpina Flash)

    This is something we are going to see more of as the new M3 and M4 battle with the 335i and 135i models equipped with the N54 (with N55's more and more getting into the mix as well). This goes down about as one would expect with the F80 M3 pulling up top. The M3 has the advantage of the DCT transmission. The Eurocharged ECU flash tune with downpipes as this M3 has boosts things considerably. Basically, a bolt on F80 M3 should make a bit more power than a bolt on E9X 335i N54 but the N54 has some additional tricks up its sleeve that this particular example is not running including inlets and E85. This particular N54 is running meth injection though and the F80 M3 S55 is not which is a factor although it is on race gas. Ultimately, these are both 3.0 liter twin turbo direct injected BMW inline-6 motors and which is faster comes down to the amount of mods and really money spent. The M3 will ultimately have the advantages of the DCT transmission and the higher redline. It also is the more complete package to begin with. It's a bit of a shame these are chase view runs on the video (it should be a crime really) but it goes to show how quick a tune and downpipes M3/M4 is and how it stacks up to a bolt on N54.

    Have you ever been one of those people waiting for a spot to open up in a parking lot only for some asshate to swoop in and grab it? Well, often times there is little one can do about it. Fortunately this Jeep owner was able to dispense a little vigilante justice of his own. Kind of makes you want to get a winch, doesn't it? Well done:

    Remarkable numbers here from the BMS F80 M3 which recently ran at the Famoso dragstrip in California. Keep in mind it is very hot out in California so setting records with temps in the 90 degree range is highly impressive. 135.50 miles per hour is the new record for the F80 M3 as well as the S55 engine platform. For further context, this trap speed exceeds any stock internal E9X M3 with a blower. Powerhaus Performance ran 10.46 @ 135.13 in a supercharged DCT E92 M3 but with a stripped out car in negative density altitude during the Winter on the East Coast. In other words, although the trap speeds are similar these cars are not equal and this F80 M3 is significantly faster. The F80 M3 on stock internals is simply capable of more than the E9X M3 on stock internals which should surprise nobody. Further details from Terry@BMS below: Hey guys, Famoso Raceway had a rare drag day last night that a few of us attended. The track was packed and weather horrible, around 90 degrees when they started running at 8pm and around 80 degrees at midnight when they stopped running. And traction was bad. But we all had a good time anyway. DA was around 2500' at 11pm. I raced our 2015 M3 w/ JB4, PURE S2 Turbos, BMS intake, BMS meth, Dodson clutch packs, and Nitto 555R tires. Full weight. And was able to set a new F80 trap record. It's actually probably a new F chassis trap record. Best of 3 runs was 11.4@135mph. Since traction was so bad after the first run I gave up trying to launch hard and would just floor it at the light with traction control one pushed. The car definitely has 10 second potential with a 60' in the 1.8s and better weather won't hurt. Jon was racing our 2015 M5 with JB4 & meth only. Due to trans slippage he limited boost to 22psi, and the car is stock weight with a heavier driver. He managed a best of ~11.7@126mph. It was his first time in the 11s in any car so he was happy. Ando was racing our 2015 M4 with JB4 only and really struggled with traction. Since he didn't have meth the high temperatures translated in to low timing values which hurt his power a lot more than Jon and myself. His best was ~11.9@120mph. Jason was racing our 435 with JB4, PURE S2 Turbo, BMS meth, and some other bolt ons, and really struggled to build boost off the line. 60's were in the 2.2-2.3 range brake boosting so we're going to have to work on improving that somehow. He ran a best of ~11.9@120mph. Ram with the 740whp M5 using a combination of BMS and ESS parts ran a best of ~11.4@132. With some tuning adjustments I can see him picking up another 2mph pretty easily. And he has larger turbos on the way. Eric (of MB fame) has as GTR now and I think his best was 10.4@133mph with around 640 all wheel hp. Damn those cars are fast! Worth noting we were all running unleaded racing fuel. I'll post up some better photos and videos later!

    Pure Turbos is continuing work on their Stage 2 turbo upgrade hardware and sent Terry Burger of BMS a set of Stage 2 S55 turbochargers with larger wheels. This F80 M3 is a DCT car with Dodson clutch upgrades and BMS previously hit 615 wheel horsepower with the prior version of the Pure Turbos Stage 2 hardware. It is in the mid 650 wheel horsepower range now. Keep in mind, this turbo upgrade has cracked 700 wheel horsepower on a manual BMW F82 M4 with BMS tuning. We expect this DCT car to approach that number with further tuning: Hey guys, Got the M3 back finally and headed over to the dyno for a little tuning. Changes since last go around: Slightly larger wheels on the PURE S2 turbos BMS S55 intake Less octane this time around: ~95 octane and 50/50 boost juice, last time was ~98 octane and a higher meth mix. General thoughts: 1) The new wheels spool a touch slower than the previous ones but seem to hold boost better towards redline. All in all doing what they should be. 2) Sorry, I didn't take the time to swap back to the OEM intake. Preemptive answer: I don't know how much of the power gains if any can be contributed to the intake vs. other changes made. 3) I found this setup on the OEM timing curve is under advanced even at this lower octane level. Going from 9 degrees peak timing (normal timing target) up to say 12 degrees peak timing (JB4 adjusted target), keeping boost the same, resulted in a ~20whp swing at high rpm. This partially explains the heavy dyno variance people see testing in different ambient weather conditions. And just goes to show how easy it is to make hard parts like intakes or exhausts look like they are adding (or subtracting) a ton of power when they might not be doing anything. 4) Note the JB4 we have on ours has a special wire set that lets us adjust the timing curve above OEM values. No one else has this at least yet. 5) When the weather cools down I'll head back with straight race gas and see how far we can push it. I'm thinking it should do around 675whp @ 34psi in 50 degree ambient weather.

    The big guns are here. This is the next level of M157 performance. Introducing the Weistec W.4 turbocharger package which is a significant step up from the standard Weistec M157 turbo package. You could potentially think of this as a Stage IV package for 63 AMG M157 based vehicles. What 'Stage' to call this is not important. What is important is that these are big ball bearing turbochargers capable of flowing 65 pounds a minute which is good for over 1000 horsepower in theory. No doubt many of you want to put that theory to the test and BenzBoost of course wants to see it as well. We can not delve too far into the expected power numbers but what we can say is significant durability testing has taken and is taking place. What we can also say is that dynos will be coming and that this package applies to stock motor setups and built M157 setups as well. This includes rear wheel drive and 4Matic all wheel drive platforms. Obviously there will be a power and torque difference between stock and built M157 engines as far as what the motors can safely and reliably produce. Also, the Weistec upgrade is developed in a comprehensive manner. Meaning you can expect OEM detail to the entire driveline. Beyond this we really can not say much only that in due time you will see it all for yourself. So what is the big deal here? Well, obviously the big ball bearing turbochargers. Read it from Weistec themselves: "The M157 W.4 Turbochargers are ball bearing turbochargers featuring CNC machined billet aluminum compressor wheels capable of flowing 65lb/min. Each turbocharger features a specifically designed compressor cover that clears all the engine accessories (AC compressor, Alternator, etc.) and makes use of the stock charge piping as well as the stock wastegate actuators. Also integral to the design is the 3 inch anti-surge inlet providing the maximum possible flow to the compressor and helping prevent compressor surge." Make sure you focus on the line that states the turbochargers clear the engine accessories. Look, a lot of people will tell you they can fit big turbos on the M157. Few people can actually make it all fit in an OEM manner. That is where the 'Engineering' portion of the Weistec Engineering name comes into play. This is work by real engineers and not some back alley tuner hack job. The stock manifold design is a bottleneck on the M157. Weistec changed the entire design as you can see to be as efficient as possible. This is important to pay attention to: "The Weistec Turbo-Folds have 50% larger port area with increased manifold cross sectional area supporting much more flow, allowing the engine to safely generate far more horsepower and torque than any other available option. Despite being a totally new and larger parts, the Weistec Turbo-Folds are designed around the use of the Weistec True Downpipes. Those that already have the Weistec True Downpipes can be assured that no extra or new exhaust components will be needed." If you already have the Weistec 'True Downpipes' you are good to go and do not need to buy more components. The logical follow up question of course is how much money for all of this? Well, that information will come in due time along with further details. For now, M157 owners should be overjoyed that the platform is taking the next step forward which you might as well call it a leap forward as that is exactly what this is. KEY FEATURES: Twin Ball Bearing Turbochargers 65 Lbs/min compressor flow Weistec M157 Compressor Covers Weistec Cast Stainless Steel M157 Turbo-Folds Custom Turbo Coolant Lines and Fittings Custom Turbo Oil Lines and Fittings Weistec Airboxes and Intake Piping Bolt on installation All hardware and gaskets are included 1000+HP Capable with supporting upgrades Designed to use Weistec True Downpipes Reuses Stock Wastegate Actuators

    Cobb's Porsche 991 Turbo tuning development continues and they are moving rapidly. Below are results for Cobb Stage I and Stage II OTS (off the shelf) tuning. These numbers are results anyone can expect with the OTS tunes and of course they can be further customized if one wishes. The torque gains massive with just the Stage I OTS tune on pump gas. They were able to pick up an additional 107 lb-ft of torque at the wheels. Stage II on pump gas takes this to 652 lb-ft of torque at the wheels for a gain of 120 lb-ft. The biggest horsepower gains come on race gas but that raises the question of diminishing returns due to cooling issues. PorscheBoost of course already explored 991 Turbo and Turbo S heat soak issues and Cobb is well aware of cooling limitations especially when tuning. Cobb is working on intercooler upgrades to overcome any limitations and push things forward. Impressive work thus far. Our Porsche Experts have been hard at work making sure we’re all set for the Porsche 991 Turbo Accessport release which is getting closer by the day! The most fun part of that process is strapping the cars down to the dyno and seeing just how much power they make after a bit of tuning. We were extremely lucky to be able to work with Porsche of Colorado Springs for the Pikes Peak International Hill Climb. That experience enabled us to learn a TON about these cars and how they react to different tuning strategies, aftermarket bolt-on parts, or differences in fuel quality. Below, we’ll take a look at some of the power gains we’ve seen. First, on an otherwise stock car followed by gains associated with an upgraded exhaust and appropriate tuning. As a note, the data in the graphs was recorded on two separate days however the delta from the baseline pulls remains accurate. Seen here is our initial Stock Baseline pull on 91 octane fuel along with a Stage 1 OTS map using 93 octane fuel. A Stage 1 map would be used on an otherwise completely stock vehicle. Power under the curve is significantly increased throughout the low and mid range. Maximum gains of around 60whp are seen between 3000-4000 RPM. Most impressive is the increase in low-end torque, with gains of over 100 ft/lbs! Next up, Stage 2. A Stage 2 map is calibrated to be used on a car with upgraded exhaust. As is evident with the power gains, the motor is able to flow a significantly greater amount of air with the freer flowing exhaust. With gains of 120 ft/lbs down low and nearly 100 hp at peak, the cars become a whole new animal. We are able to be a touch more aggressive utilizing 100 octane fuel, this will be a great option for customers interested in tracking their car where detonation resistance is key. Stay tuned as we continue development on this platform. At this point, the cars will really need an improved cooling system to make any additional power. We’re already in contact with top intercooler providers in the industry with intentions of overcoming the next bottleneck in power.

    Renntech took their tune only W205 Mercedes-AMG C63 to the dragstrip in Germany for some 1/4 mile runs. The car features just a Stage I tune and is on street tires along with pump gas. There are no further modifications and the exhaust is stock as well with stock downpipes. What is important to note is this not a dedicated 1/4 mile strip as much as a dedicated yearly event that the car was run at. That means the organizers choose a location and that tarmac is what the cars run on. Renntech mentioned the traction was not as good as previous years. Parking in the dirt between runs instead of on asphalt no doubt contributed to poor off the line traction. You can see the C63 easily go sideways for yourself in the video below. That said, they managed an 11.947 @ 122.60 miles per hour with a 1.983 short time. A 1.7X 60 foot should be relatively easy on a prepped strip meaning this car is capable of mid 11's. Especially in the winter and not during the summer. Definitely encouraging results and we expect the W205 C63 to go deep into the 11's soon as temps start dropping. For additional context the GAD C63 AMG setup that broke into the 9's at Yas Marina ran 10.6 at this event at the Hockenheim track.

    A JB4 tuned F82 M4 is definitely a quick car especially with catless downpipes as a supporting mod with race gas. This BMS JB4 equipped M4 is running Map 7 so it means business. The cars it is running are two stock Hellcats with one being a Charger and the other a Challenger. Stock Hellcats are formidable and capable of running 10's at over 126 miles per hour. The 707 horsepower twin screw supercharged Hemi V8 is no joke. They are heavy boats though at ~4500 pounds so the Hellcats are carrying roughly a 900 pound weight penalty. No fancy DCT transmission for the Hellcats either like the M4 is equipped with. Shift speed and weight are on the BMW's side here but raw grunt is on the side of the Hellcats. The first run video features the Charger and there is some miscommunication on lining up the run. While the Charger is trying to count down it appears the M4 is honking and jumps. The Charger impressively is able to run the M4 down. This clearly shows it is the stronger car to make up such a deficit. The subsequent runs with a more even start illustrate this as the Charger pulls. The Challenger video below has some quick honks and some miscommunication on the starts as well but the very first run where they both get a decent start shows the Challenger able to edge the M4 out. Interestingly, the Charger based on this result seems to be the slightly faster Hellcat. It would be fun to see the Hellcats run each other. Regardless, to put this in context we are talking about a modified BMW M4 on race gas going up against stock Hellcats and losing. That shows just how potent and formidable the Hellcat is. If any F80 M3 or F82 M4 intends to play with a modded Hellcat on the highway they better be packing some heat likely in the form of upgraded turbos. DCT M4: JB4 Map 7, AR DP's, 100oct Both Hellcats are stock automatics

    We spend most of our time on speed and power here but it never hurts to look good while going fast. This 6-Series certainly looks good with the Prior-Design F13 650i widebody kit. The fitment and paint all look to be very well done almost as if OEM. Which is interesting as we have members here who have purchased Prior-Design products only to report poor fitment. There certainly is likely a difference between the cars and parts used for marketing such as this and what customers actually get simply based on reports and results posted on this network. That said, this particular example of Prior-Design's work combined with wheels from Vossen certainly looks good. Brembo brakes and a GT Haus Meisterschaft exhaust help finish things off.

    BMW has become fat. Say what you want about BMW focusing on weight loss the reality is that 'Efficient Dynamics' is nothing more than marketing. They are missing their weight goals with the coupes let alone the hardtop convertibles that add over 400 pounds to the cars. The hardtops add so much weight that BMW makes sure not to employ a hardtop on the F12 6-Series models which already are over 4000 pounds for the coupes. The soft top adds ~250 pounds. The hardtop on the E93 M3 convertible added 450 pounds over the coupe. The current F33 4-Series with its hardtop carries roughly 400 pounds more than the coupe. That is a massive difference. The current rumor is that BMW will switch completely to soft top convertibles to save weight. BMW is not the only one rumored to be doing this. Mercedes is expected to go to a cloth top on the next generation SL. Will it happen? Who knows. This is nothing more than a rumor circulating right now. There is no official source or anything of substance to even quote. Just news for the sake of news.

    Very impressive Stage 2 M178 tuning numbers here from Renntech. As you may recall, Renntech started work on the M178 motor early this year. They showed a baseline of 531 crank horsepower and 472 wheel horsepower. They have the AMG GT S with their turbo upgrade and downpipes up to 682 crank horsepower or 625 at the wheels on their dyno now. Those are some major gains. Torque alone is up by 167 lb-ft over stock. What is also nice to see is how flat the M178 torque curve is once the motor spools and how the torque curve does not really start to drop hard until past 6500 rpm. The M178 in general is definitely breathing better up top than the M177 in the C63 especially this example. Renntech previously shared an acceleration video of their intermediate tuned AMG GT S running up to 195 miles per hour and this time they take it to 199 miles per hour with the Stage 2 setup. The car accelerates hard with the Stage 2 package and the gearshifts look to be about instant. They get to 198 miles per hour in no time. It's incredible how easily the car gets there and with no drama whatsoever. This car is fast. It will be interesting to see how much further Renntech takes it on the turbo upgrade with race gas but for now they obviously are not pushing the transmission beyond its limits.

    Very impressive numbers here from AMS Performance who has the quickest and fastest dual clutch transmission equipped Audi R8 in the world. Earlier this year the BoostAddict network wrote an article on AMS revising their R8 5.2 V10 twin turbo system for more power on a built motor and that they would be offering dual clutch transmission upgrades for the R8 and Huracan. Their Stage I R8 and Huracan DCT transmission upgrades sure look to be solid considering the AMS Performance twin turbo Audi R8 V10 managed a 9.93 @ 157.14 in the 1/4 mile. This makes for the quickest and fastest dual clutch R8 in the world. The Stage I transmission upgrade is good for over 1200 horsepower and they claim that the torque capacity is increased by 50%. This is without any changes to the clutch basket and just changes to the discs and clutch plates themselves. Grooves in the friction plates are designed to increase fluid flow over the plates. It is safe to say there is more room in their built motor turbo setup and due to this a Stage 2 transmission upgrade is on the way which will modify the pistons and clutch basket. Exciting times for the dual clutch R8 and Huracan.

    You being an avid BimmerBoost reader and BMW enthusiast know that BMW's convertible models are heavier than the coupes. You also know BMW is considering going to a soft top on all of its convertible models due to how heavy convertible models such as those in the 4-Series lineup are getting. 4041 pounds is evidence of that which is what Car and Driver measured the curb weight of a manual 2015 F83 M4 at. Yes, a DCT (dual clutch transmission) version will be even heavier and closer to 4100 pounds. That is not the weight one expects for this class of car. Even with the roughly 500 pound weight penalty versus the coupe which of course depends on options the manual performs admirably. It obviously will be slightly slower than the DCT option but Car and Driver still managed a 12.4 @ 113. In other words, performance roughly on par with a previous generation E92 M3 coupe. That is the difference 500 pounds makes. The weight also takes its toll on the handling as the skidpad grip is .94g and braking suffers as well compared to the F82 M4 coupe. The best way to make a car more efficient is to make it lighter. BMW is supposed to be about Efficient Dynamics, aren't they? Despite the curb weight over 4000 pounds the M4 certainly is not a bad way to go for drop top motoring and most owners will not care about the weight. One does not choose the drop top for maximum performance. They choose it to be seen.

    A little over a week ago BimmerBoost posted an article regarding member @RingMeister01's problems with ESS-Tuning and one of their dealers regarding a turbo upgrade package for his F82 M4. You can read the details in that article if you like. What this raises is the question as to what recourse do you have if a tuner or one of their dealers decides to line their own pockets at your expense? This is not the first time we have seen something like this happen. Oh no, the unfortunate truth is it happens far too often. We have seen it with ASR Engineering. To this day BimmerBoost member @George Smooth is owed money by ASR Engineering. We have seen it with Discovery Automotive. You can add RSI Racing solutions to the list as well. Hennessey has quite a few horror stories that have been swept under the rug from before the big automotive forum days. The point ultimately being is it happens way too often and often the customer just takes the loss and moves on. These crooks then go on the prowl again to rinse and repeat. Fortunately @RingMeister01 is not just taking this lying down. Oh no, he contacted his attorney and is fighting back. Too many people though just eat the loss. The previously mentioned George Smooth does not live in the USA so what is he really to do? Try to fight in court from overseas over a few thousand dollars? It is a bit more than a few thousand in this instance and ESS-Tuning seems to be standing by while their dealer 'IMG' charged more than he was supposed to in order to line his own pockets. This is a guy on the forums who is an ESS cheerleader and now decides to make a few bucks on the side by slinging their parts for them. That wouldn't be a problem if it was done honestly. It wasn't: A fanboy on a forum basically decided to make some extra money by dealing ESS parts and ESS encouraged him to do so. Now that it comes to light that the dealer overcharged @rinbermeister01 to the tune of over $16k spent ESS is leaving him hanging and the 'dealer' is laughing all the way to the bank. Imagine you were out over $16k. Would you just roll over and take it? Too many people have. @RingMeister01 isn't rolling over though and we commend him for standing up for what is right. Many tuners can get away with hustling people because they are overseas or by declaring bankruptcy and starting again. Neither of those are an option here. We wish him luck and let this serve as a warning to all our enthusiasts regarding whom they do business with. It's a story that should not repeat itself but yet we see it frequently.

    Improving on the factory BMW airbox design for the F80 M3 and F82 M4 is not easy. It is not like the BMW engineers do not design efficient parts themselves but they do have to work within a certain budget and with BMW suppliers as well as deal with strict regulations. As we all know there is room to improve on many BMW factory parts including something like the intake system on the S55 motor in the F80 M3 and F82 M4. Gains really show when someone is running a tune or higher boost as the factory system becomes more of a restriction at that point. Look at the dyno results on a Mustang dynamometer here from AWE-Tuning. The aftermarket part and the factory part perform about the same until the motor is past 3k rpm. At that point the S-Flo system provides greater flow on the test car which is running their piggyback tune and exhaust system. At the factory power levels gains will be minimal but this is a mod for that person trying to extract every last horse and remove restrictions. What the dyno results prove is that the factory intake can be made more efficient and this pays dividends as the motor is pushed harder. Is this system worth the $1595 they are asking for it? Well, that is up to you. For the cost conscious the recently released BMS system is quite the value alternative. The AWE piece sure is pretty though and offers OEM fit and finish.

    The previous W204 generation C-Class brought with it for the first time a C-Class AMG coupe and sedan. A coupe will once again be offered but Mercedes-AMG appears to really be trying to separate the coupe from the sedan this time around by giving it a wider stance with a more sporty emphasis. BenzBoost jokes that the C63 is just a mini-E63 due to its heavy curb weight and how it is more dragster than sport sedan but the coupe may change that. Just look at the wider tires, 255's in front and 285's in back. The sedan comes with 245's and 265's respectively. The wider stance is going to help on the track but what would really benefit the coupe would be if it offered better weight distribution and a curb weight significantly less than the sedan. Most tests peg the sedan over 3900 pounds. That is just too heavy for a true track car in this segment. The coupe may change all that. It will still of course have the MCT automatic and the M177 twin turbo 4.0 liter V8 but the real changes coming appear to be geared toward making the coupe a better track weapon. Expect an official reveal any day now.

    It has been a while since BMW introduced the M6 GT3 set to replace the Z4 GT3. BMW Motorsport director stated the 24 Hour Dubai and Daytona races in 2016 are what they are targeting, "That’s obviously what I think customers would like to run and that’s what we’re clearly aiming at." Those are big endurance races and certainly a good time to make a debut. They are also still a ways off which means testing can continue and the car should be ready to go next year. What BMW is doing is tweaking and testing the car for privateer teams, "That’s the focus of our development program is that we hand over a car to the customers that’s already developed, that not necessarily has raced in the hands of a works effort from our side. It’s competition. But as we’ve said before and I would like to stress again, this is really customer racing. Therefore, for us, it’s not an option to enter a prototype on a works level and compete against our customers or potential customers. This is customer racing and nothing but." Do not expect a factory backed effort with the M6 as you saw with the Z4 and M3 previously. As a reminder the M6 GT3 features a 500 horsepower 4.4 liter twin turbo V8 based on the S63TU engine design with a dry sump oiling system. The power is routed through a six speed sequential manual gearbox. With a dry weight of 2866 pounds it should move quite quickly.

    It is only a matter of time until all wheel drive M3's and M5's hit the road. BMW can not keep adding torque with turbo powerplants and still maintain good rear wheel drive traction. Mercedes-AMG simply decided to make the E63 in the United States available only as a 4Matic all wheel drive due to the twin turbo V8 easily making the rear wheels go up in smoke. The downside to this is added weight, understeer, and making the car more into a German dragster than something to hit the canyons with. The next generation M3 will go down this route. BMW will borrow hybrid technology no doubt from the 'i' brand packaging it with the 'M' brand for some nice internal cross-brand promotion. They will then adopt some lightweight carbon pieces convincing everyone the 'i' brand was worth the investment due to development paying dividends on new models. The marketing department is probably already salivating at this prospect and all they need is a nice little bow to wrap the press release in. Is an all wheel drive hybrid turbo M3 with 500 horsepower and factory water injection a bad thing necessarily? No. It just does not sound anything like an M3. It sounds like the car will be further dulled from the sharp driving tool it used to be and turned more into something with a lazier profile that does all the work for the driver. With torque expected to be boosted by at least 73 lb-ft no doubt there will be those that do not mind the added weight of the all wheel drive system in exchange for more traction off the line. E63 AMG buyers do not seem to mind but the E63 is not an M3. The car is not expected until 2020 at the earliest but with emissions standards tightening a hybrid M3 is practically a certainty especially with BMW's gigantic investment in the 'i' models. What we can be certain of is the next generation M3 will have more in common with the i8 than any M3 that preceded it. Source
