    Carbon fiber wheels are the new big thing. For years, wheel companies made carbon overlay rims to get the look of carbon fiber but the aftermarket now is beginning to offer a nice selection of full carbon fiber wheels. Keep in mind Ford sells the Mustang GT350R right off the showroom floor with carbon fiber rims. ESE Carbon is a new company and honestly we do not know much about them. There is no feedback to go on but BoostAddict member @BerndV ordered a set for his E63 AMG. We'll see what he has to say about them. On paper the rims are incredible. A 19x9 wheel weighs only 11 pounds. That is significantly lighter than anything else on the market. The wheels are available in sizes ranging from 18 inches to 22 inches. At $2000+ per wheel these are not cheap but it is pricing on par with a set of HRE wheels which are far more about style than substance. Outfitting an all wheel drive car with these rims will make a substantial difference in performance by reducing unsprung weight at all four corners. Now to see people start running these rims and their feedback.

    Isn't the Supra supposed to be the highway monster? This is a very impressive run by a single turbo BMW 335i N54 with a Precision Turbo 6766 single turbocharger conversion. The 335i was in kill mode at roughly 40 psi of boost (on the stock motor) and it shows. The Supra just gets walked. The video is not the best quality but you easily see what happens. This is a stout highway BMW.

    The S54 proves yet again what a beast it is. If you are going to call any BMW engine the German 2JZ it's the S54. The proof is in the 902 horsepower and 644 lb-ft of torque at the wheels Dynojet pull from a Maximum PSI turbocharged E46 M3 S54. Oh, and this is tuned on the factory ECU. Fuel is E85 ethanol and it certainly helps that there are no direct injection fuel system limitation, right? Yet another thing the S54 has in common with the 2JZ for those who keep track of those kinds of things. In all seriousness, congratulations to Maximum PSI. This is incredible power on the stock internals and a tremendous record. It is great to see naturally aspirated M engines show what they can do when properly boosted and tuned. Hats off to the best six cylinder BMW engine ever made.

    If you thought Sterling BMW in Newport Beach, California was ridiculous for asking $60k over sticker then you might have some trouble articulating how you feel about the $100k+ over sticker Santa Maria BMW is asking. This would be funny if it was not so sad. First of all, why is it Califonia dealers asking these absurd markups? Secondly, Santa Maria BMW is looking for someone so stupid that they can't even add. They say they want a $100k market adjustment yet the asking price is $245,815.00 meaning it is actually a $110k markup. They're looking for someone so dumb that basic arithmetic escapes them. This is just a new low for BMW dealers.

    Sterling BMW is located in Newport Beach, California. There certainly are a lot of posers in Orange County but there likely is not anybody dumb enough to pay an extra $60k on top of the already absurd BMW M4 GTS MSRP. Who in the world would be stupid enough to pay over sticker for a track car that is a performance failure? Let's quickly recap what the M4 GTS offers. A minimal performance increase over the standard M4 thanks to suspension upgrades, aerodynamic changes, a new tune, and water injection. You can literally get coilovers, an even stronger aftermarket tune, and add in your own water/meth system on a standard F82 M4 and outperform the M4 GTS while saving $60,000. The M4 GTS can not beat a single performance car in its price range around the track and several that are much cheaper embarrassingly spank it. BMW did not shave the weight they claimed they would and the car does not meet any of the performance targets they claimed either. The car amounts to nothing more than hype. The M4 GTS is already overpriced at $134,200 let alone with a $60k market adjustment. They adjusted the price in the wrong direction. Good luck finding that sucker Sterling.

    Very cool race to see here and the S55 ECU flash tuned BMW F80 M3 is going up against very stout competition in the McLaren 650S. To give you an idea of how capable the 650S a BoostAddict member took his stock MP4-12C to the strip which is slightly less powerful and ran 10.6 @ 135. The 650S is a very fast car and considerably lighter than the F80 M3. Even in stock form it should be favored over a bolt on tuned M3. We do not know the full specs for the M3 here but it has an ECU flash and assume downpipes along with ethanol, meth, or race fuel. Are the turbos upgraded? It sure seems like it. The M3 wins the first race. It pulls as the race goes on which just shouldn't happen. The second race however has the 650S get a better launch and it destroys the M3. The slip doesn't reflect the second result as it shows the M3 as trapping higher and being close to even running 10.5 as well: Where is the second slip where the 650S dominates? Conveniently left out.

    Perhaps stock is a bit misleading here as there a couple things to be aware of. The tires being the biggest change as the car is running Michelin Pilot Cup 2 tires. Besides the tires the car is completely stock making this laptime truly amazing. The modification that really seems to make the difference is the driver mod. The person at the wheels is Manuel Metzger. Not only does he drive for Team Black Falcon he was part of the winning team at the 2016 Nurburgring 24 Hours. Suffice it to say, this guy can drive and knows the track. It shows in the 7:22 laptime which is set with traffic. This is an incredible run. We already knew the AMG GT S was very capable in the corners from MotorTrend's best Driver's Car 2016 test at Laguna Seca but to see it perform at this level on the 'Ring is truly spectacular. To give you an idea of how quick this is a Ferrari 488 GTB was timed at 7:21 and the last Porsche 911 GT2 RS (997) managed a 7:24 on a full lap. This is a BTG (Bridge to Gantry) lap but very, very quick and with a tune this GT-S is going to be a monster.

    This is not a giant scoop or anything but BimmerBoost was notified of a couple images circulating that are reported to be of the new M5. Why does this matter? Because a BMW employee apparently sent these out so that means they are real. What is revealed here? Nothing of any real substance. You can get an idea of the styling direction as far as the front bumper and rear apron are concerned. Nothing too earth shattering but expect some graphic artists to be able to render what the next generation M5 will look like now with a high degree of accuracy.

    Great news here from @Pure Turbos. First, you will notice the competitive pricing on their Stage 2 'HiFlow' and 'DD' N54 turbo upgrades. What is truly remarkable though is that Pure Turbos is stepping in to help those with failed Hexon turbos by offering a 10% discount for those affected by Hexon's demise. That is not something they have to do and BimmerBoost applauds Pure Turbos for standing up to help the community. Most businesses would just try to make as much money as they could but Pure Turbos is showing respect for the platform and even people who gave their business to the competition. Incredible. Full details below: Dear N54 enthusiasts, We appreciate the support. We are pleased to continue offering the best and most reliable twin turbo upgrades available for the N54 community. We would like to announce new PURE pricing and options. We have sharpened our pencil on N54 PURE Stage2 pricing. Production efficiency has improved with our in-house machine shop and allowed us to offer even more attractive pricing. We have also settled on a hexon hand-out, to help those victims caught in the hexon failure storm. We run larger wheels, so the blown hexon turbos are re-machine-able. Therefore we can offer a 10% discount to those who return hexon cores. This must be done directly with pure. There’s no advantage for us here. It’s simply a nice gesture to help the community. Lead-time: 2-3 weeks. We currently have 22 pending N54 Stg2 orders which are being finished up now. We now have enough parts back in stock to build an additional 100 sets. We are seeing an exponentially increasing amount of new N54 enthusiast owners daily. We see a lot of these new faces jumping to the cheapest option available. Well, that's exactly what happened with the hexon turbo customers. We always recommend choosing a tested and proven product. N54 PURE Stg2 "HiFlow" - $3595 + core exchange Our well known Stg2 option which is documented on many customer’s cars to be capable of 650-700whp N54 PURE Stg2 "DD" - $3095 + core exchange This new option is intended for most customers. It was engineered for 550-600whp max. We have seen as much as 550whp on the stock HPFP only, and an easy 600whp with a meth kit. Based on collective info and our own experiences, above 600whp is the point at which you greatly increase your chance of stock N54 engine damage. This also happens to be the power level that can often result in 6spd Auto Trans slipping and damage. This is why we consider this new turbo option appropriate for most of you. Low mileage engine/trans seem to do better and last longer. But no doubt, 600+ is where the risk substantially increases. For those of you with goals of 650+whp on stock engines, be well aware you are running a high risk of engine damage. Be prepared to possibly spend money on a replacement motor. Commonly $4.5k-$6k for a good used motor installed, and $6k-$10k for a forged motor installed. This is not intended to scare or deter anyone. It’s just something that needs to be said and understood. Have we all seen stock internal N54 engines make 700-800whp? Yes. Do most of those engines die? Yes. Our N54 upgrade turbos have proven to be strong and reliable. The handful of issues we have seen, out of the hundreds now sold, were due to oil contamination. We are finding it is common people wait for their stock turbos to fail before upgrading. Often times, contamination from the previously failed turbos get trapped in the oil filter housing and oil cooler. So make sure to flush all that out before installing new turbos. Feel free to contact us for inquiries: or 760-721-7669 Thank you!

    Some renderings here after the BMW G30/F90 M5 leak although the artist does not quite get all the details right. Regardless, it gives you an idea of how the new M5 will look. A sedan of course is on the way but what about a wagon variant? The only high performance wagon you can buy from the Germans in the USA is the E63 from Mercedes-AMG. If BMW is going to insist on making a fat all wheel drive M5 with a ton of torque at the very least they could make it more useful. If you are already selling M SUV's how will a wagon hurt?

    Is the M4 GTS a hardcore car or is it made so BMW appears to still cater to the enthusiast? You would think a dedicated and limited edition high performance BMW track car would shut up critics like the one writing this but it has done the exact opposite. The BMW M4 GTS is just an exercise in BMW looking like it still cares about driving enthusiasts. A $134,200 exercise at that. What do you get for that money? A bit more power out of the same S55 engine thanks to a new tune and water injection. Aerodynamic upgrades, different wheels, suspension upgrades, weight loss (not really), and a roll cage option. That stuff all sounds cool until you factor in the car is twice the price of a standard F82 M4 and literally can't beat anything in its price range on the track or many cars well below its price range. What's hardcore about building a tarck car that fails at what it is supposed to excel at? What's the point? Why even bother? If going all out then go all out. Don't half ass it. The M4 GTS does look fast standing still. Which keeping it parked next to a Mustang GT350R is the best option for an owner who would like to stay close to the cheaper Mustang as he won't be able to do that on the track. What does MotorTrend think? Well, they state the GTS is more like what the M4 should have been. It goes to show how tame BMW M cars are now. They really aren't motorsport specials as much as just cars with more power than the models beneath them. They simply got away from what made M the most respected letter in the automotive world. Fortunately, MotorTrend points this out. MotorTrend says water injection is what allows BMW to make the power they do on 91 octane. The standard M4 can make the same power and even more without water injection on pump fuel so that isn't quite true. Water does help with tremendously with its cooling effect. It works but it is also somewhat of a gimmick. You can easily add water injection to your own car and even mix in some methanol to provide a massive benefit. The M4 GTS is supposed to be a track special yet while on the track the stability control constantly flashes. Yes, you can turn it off. The rear end will be coming around easily though as the motor is all about torque down low versus top end horsepower. Drifts look cool, right? They just aren't the fastest way around the track. Basically, the M4 GTS is what the M4 should have been. To get the car BMW should have made by paying twice the price is ridiculous. Especially considering there are many better cars for that money. You are better off in a 911 Carrera at $90k. You are better off in a Mustang GT350R. You are better off in a Corvette Grand Sport. Quite simply, you are better off not buying the M4 GTS. The car is two seconds quicker than a standard M4 around Laguna Seca. Why not just get better rubber, coilovers, and a tune for your M4 while pocketing $60k instead? The M4 GTS was supposed to remind us of how good BMW can be. Instead, it reminds us of how far BMW has fallen.

    An independent drag race between two enthusiast ars that directly compete in the same segment is something we definitely like to see. Both vehicles are turbocharged and direct injected six cylinder models but the ATS-V has a larger 3.6 liter LT4 V6 and the M3 utilizes the 3.0 liter S55 I6. The heavier Cadillac (by roughly 300 pounds) gets off the line much better than the M3. The ATS-V appears to be an automatic example. The M3 looks to be running it down but seems to get off the gas early. The M3 runs 11.604 @ 105.89 and the ATS-V runs 11.579 @ 119.82. The ATS-V has a tune but is on stock tires. We do not know if the M3 is tuned or not but it was on drag radials.

    Density altitude will have an effect on the Porsche 918 Spyder but it will not be to the degree other naturally aspirated V8's are affected. Why? Because electric motors don't care about air quality so hybrid cars can mitigate conditions better than non-hybrids. Even in hot Houston weather this 918 Spyder runs 10.1 after 10.1 in the 1/4 mile. The car basically does all the work for you so the consistency from the all wheel drive hybrid supercharger is no surprise. In the future as more cars goes to hybrid drivetrains and entirely electric cars become the norm complaining about hot weather or elevation at the track will be a thing of the past. DOHC 32-valve 4.6-liter V-8, 608 hp, 391 lb-ft; 2 permanent-magnet AC synchronous electric motors, 127 hp (front), 154 hp (mid); combined power rating, 887 hp, 944 lb-ft; 6.8-kWh lithium-ion battery pack

    Damn. 1211 to the tire with a Procharger F-1A 30 psi of boost? Awesome. That power comes at 7600 rpm on E85 fuel. Obviously ditching the Ford GT positive displacement blower for a centrifugal will result in completely different driving characteristics but who can argue with 1200 to the wheels? There is more power to be made. There is the Procharger F-1X which outflows the F-1A by quite a bit and is easily making quadruple digits on LT4 motors. This owner will be putting the larger F-1X on the GT next. What will it hit?

    Aston Martin is teaming up with Red Bull Racing. It makes sense as Red Bull has done a tremendous job in Formula 1. Their resources will only help. Not to mention Red Bull's deep pockets which will be needed to achieve the laudy goals. They want a 1:1 power to weight ratio. Not one horse per pound. One horse per kilogram. It certainly is achievable but they are using a mid-mounted naturally aspirated V12. That likely means there will be electric motors augmenting the naturally aspirated powerplant. If so, that means increased weight. They also want it to hit 200 miles per hour in 10 seconds. Oh, and 0-200-0 in 15 seconds is being tossed around. These sound like video game numbers. Right now there are a lot of big claims about the car and nothing is set in stone. They do not even know how many they will produce (if they even do) as a number under 150 units is expected. Are there 150 people in the world willing to spend $3+ million on a supercar? Yes. Only if it is indeed the best car on the market. Time will tell what, if anything, comes of this. 5 July 2016, Gaydon, England: Aston Martin and Red Bull Racing are today revealing their ground-breaking hypercar; codenamed AM-RB 001. The product of a unique Innovation Partnership between the British luxury brand and eminent F1TM team, this ambitious, uncompromising and wholly extraordinary collaboration combines the vision and skills of two world-leading brands to create a road car the like of which has never been seen before. The three men charged with realising this shared vision are Adrian Newey, Red Bull Racing’s Chief Technical Officer and the world’s most successful F1TM designer, Marek Reichman, Aston Martin EVP and Chief Creative Officer and David King, VP and Chief Special Operations Officer. Together they spearhead a formidable alliance. One that combines more than a hundred years of specialism – both with heritage, making some of the world’s most beautiful and charismatic GT cars, and with technological brilliance and relentless pursuit of speed and efficiency that has seen Red Bull Racing excel in the ferociously competitive world of Formula One. Reichman and Newey are working closely on all aspects of the project, striving to ensure the AM-RB 001 is an unprecedented fusion of form and function: a car engineered to be entirely useable and enjoyable as a road car, but with the capability to perform like no road car before it on a race track. For those who crave an even more intensely focused driving experience, a track-only AM-RB 001 is also in development, the projected performance of which is in line with that of today’s LMP1 Le Mans sports prototypes. Built around a lightweight carbon fibre structure, the AM-RB 001 boasts truly radical aerodynamics for unprecedented levels of downforce in a road-legal car. Thanks to the genius of Newey’s design much of this downforce is generated through underfloor aerodynamics, leaving Reichman free to craft a pure yet breathtaking dramatic form that elegantly expresses both the AM-RB 001’s cutting-edge dynamism and the unmistakable essence of Aston Martin. Uncompromising in all respects, the AM-RB 001 is a bespoke machine from the tyres up. It will be built by David King and his team at Gaydon, in the purpose-built facility created for Aston Martin’s original hypercar, the One-77. More details of the AM-RB 001‘s technical specification will be revealed in due course, but its heart is a new, mid-mounted, high-revving, naturally aspirated V12 engine with the potency to achieve a 1:1 power-to-weight ratio; 1 bhp per kilo of weight. To cope with the extreme aerodynamic loadings at high speeds yet deliver the on-road usability and comfort levels that sit at the heart of the concept, the AM-RB 001’s suspension system will feature innovative technology and employ principles honed by Newey over his thirty year career. Likewise, the transmission is a clean-sheet design conceived by Newey and developed by Red Bull Advanced Technologies. While boundary-pushing performance is clearly of paramount importance, so too is exceptional efficiency and packaging. Newey’s unrivalled knowledge has enabled the AM-RB 001 to be extremely light and compact, yet offer genuine comfort and space for driver and passenger and house a V12 engine. Adrian Newey, Red Bull Racing’s Chief Technical Officer, says of the AM-RB 001 project: “I’ve long harboured the desire to design a road car. The formation of Red Bull Advanced Technologies brought me a step closer to realising that ambition, but I believed we should work with an automotive manufacturer. Aston Martin was at the top of my list. The synergy between Red Bull Racing and Aston Martin is clear. I knew Red Bull Racing had the ability to handle the pure performance aspects, but Aston Martin’s experience of making beautiful, fast and comfortable GT cars is of great benefit to the project. I’ve always been adamant that the AM-RB 001 should be a true road car that’s also capable of extreme performance on track, and this means it really has to be a car of two characters. That’s the secret we’re trying to put into this car - the technology that allows it to be docile and comfortable, but with immense outright capabilities”. David King, Aston Martin’s VP and Chief Special Operations Officer, adds: “Working at Aston Martin means you get to be a part of some truly special projects, but the AM-RB 001 is a dream - a true once-in-a-lifetime opportunity. Of course it’s a huge engineering challenge, too, but the game-changing objectives of this programme have a uniquely energising effect on everyone involved. We have world-class people and facilities at Gaydon. We’re all motivated to achieve great things and take Aston Martin to the absolute pinnacle of road car performance”. Marek Reichman, Aston Martin’s Chief Creative Officer, says of the AM-RB 001: “Working so closely alongside Adrian and an organisation like Red Bull Racing is a fabulous experience. By definition the objectives we’ve set for the car ensures there has never been an Aston Martin - or any car, actually - quite like the AM-RB 001. The shared challenge has been finding that magical tipping point where we achieve the most efficient engineering solutions and the most beautiful styling solutions without any compromises. My personal challenge has been expressing the AM-RB 001’s extraordinary performance and the unique way in which it delivers that performance. Its style reflects its revolutionary nature, while possessing the form and beauty that makes it unmistakably an Aston Martin”. Dr Andy Palmer, Aston Martin President and CEO, commented: “The AM-RB 001 is a truly remarkable project and something of which I’m extremely proud. To have Aston Martin working alongside Adrian Newey, Red Bull Racing and the invaluable assistance of project partner AF Racing AG is an extraordinary creative collaboration. One that unites the very best of road and race car thinking. As the project gathers pace its clear the end result will be a truly history-making hypercar that sets incredible new benchmarks for packaging, efficiency and performance and an achievement that elevates Aston Martin to the very highest level”. Christian Horner, Team Principal, Red Bull Racing said: “Red Bull Racing has always steered an innovative course in our ongoing development of a competitive Formula One car. The conception and modus operandi of Red Bull Technologies has been to apply our expertise to truly progressive projects and partnerships. Our relationship with Aston Martin and the realisation of the AM-RB 001 is pioneering and borne of our synergies and desire to break new ground. The AM-RB 001 is the inspirational product of this collaborative spirit.” Continuing the on-going Innovation Partnership, the task of engineering the AM-RB 001 will be shared between Q by Aston Martin Advanced and Red Bull Advanced Technologies, with production taking place at Aston Martin’s Gaydon facility. Total volume will be between 99 and 150 road cars inclusive of all remaining prototypes and 25 track-only versions, with first deliveries commencing in 2018.

    Eurocharged Canada already has this turbo upgrade and is doing the tuning. @Pure Turbos did not want to reveal this early but with some nudging from BenzBoost we can provide a small preview. This will be yet another option which joins Pure Turbos expanding Mercedes-AMG offering turbo upgrade offering. The M133 is already a beast stock so it will be interesting to see how much more we get out of this hybrid upgrade. As soon as Eurocharged Canada finishes the tuning we will bring you the pricing and dyno graphs. Exciting times ahead on the platform.

    The M133 2.0 liter four-cylinder is already pushed pretty hard by Mercedes-AMG. Before the 2016 facelift which bumped up the power to 381 horses and torque to 350 lb-ft it made 354 horsepower and 332 lb-ft of torque at 26 psi of boost. Many said it was maxed out and we know that is not the case as Mercedes themselves increased output. However, how much room is there really with just ECU tuning? Plenty it turns out. The peak horsepower increase from the baseline here may only be 18 but as you no doubt know how to read a graph you can see a massive increase in torque down low. There is almost 150 lb-ft more torque as early as 3500 rpm after the tune. Keep in mind these are independent 91 octane pump gas results. With that much of a torque increase the CLA45 is really going to move off the line. It looks like for big gains up top a turbo with a lot more flow will be necessary.

    You're standing around at an intersection in Prague when suddenly you see a pit crew rolling out tires. They stand there waiting for a car to arrive. That car is a 911 GT3 RS. Fitting, as it is about the closest thing to a race car for the road you can buy (short of a Viper ACR). People begin to cross the intersection and the pit crew goes to work. They quickly jack the car up and change the tires. They manage to get this all done before the light goes green. What's the point? Promotion, naturally, but it's certainly cool to see.

    Solid numbers here from Champion Motorsport's 991 Turbo and 991 Turbo S turbocharger upgrade package. Tuning is done through an ECU flash and GIAC has been working with Champion on the tuning. The result is 659 wheel horsepower on race fuel and 618 wheel horsepower on 93 octane pump. You can compare these numbers to tune only figures on the stock turbochargers. Essentially, you get another 100 wheel horsepower with this upgrade and just under 100 more lb-ft of torque at the wheels. If you want more power and torque you will need to go to a bigger set of turbos and also look into PDK transmission upgrades.

    The big question with the upcoming Corvette ZR1 is what Chevrolet is doing to the motor. Will it have the rumored LT5 turbo V8? Will it just be a tweaked supercharged LT4 out of the Z06? Well, this spy video of a pair of ZR1's testing does not help answer any of those questions. It looks like there might be an upgraded intercooler in the front bumper but with grainy cell phone video you can't really tell. You can't hear turbos either. Basically, all this video shows is the cars are still in the road testing phase. You can rest assured Chevrolet listened to complaints about the C7 Z06 and the ZR1 will likely feel far more planted and it won't suffer from any heat soak or tuning issues. Expect it to dominate the competition and dethrone the Viper ACR.
