    Incredible dyno numbers here from Pure Turbos from their Stage 2 N54 turbo upgrade. If the video posted a couple days ago showing an automatic Pure Turbos upgraded 335i running away from a FBO (full bolt on) GTR did not convince you these turbos are the real deal then these dyno results definitely should. The 683 rear wheel horsepower peak figure is a new automatic stock frame turbo record on the platform. It is important to point this out with the automatic transmission being known for having issues handling power and torque on the N54 platform. Regardless, this transmission is holding and putting down some impressive numbers. Here are further details from Pure Turbos as well as graphs at multiple boost levels: We strapped the car to the dyno one more time this morning. Reminder: This is an auto trans car, running e50 + meth, and stg1 inline LPFP! First three runs were: file_18 - Map3 add 70 - 601whp file_19 - Map6 28psi to redline - 657whp file_20 - Map6 30psi to redline - 679whp We then bumped boost to 30.9 for a few runs, messed with duty bias a bit. Here's all the runs together: Also, here's another log from another N54 PURE stg2 car showing spool. AT car in 4th gear, stock inlets. Hits target at 3293 rpm. I don't want to hear another word about spool!!!

    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?

    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="https://instagram.com/p/6DctcYuqIe/" 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: http://shop.ford.com/build/en/home.html/mustang/?gnav=header-cars#/select/Config%5B%7CFord%7CMustang%7C2016%7C1%7C1.%7C900A.P8J.....COU.SLB.~YZKAA.SHB.LESS.%5D

    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 clichι 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.

    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.

    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:

    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.

    The Pure Turbos Stage 2 N54 upgrade sure looks like the real deal. The turbo upgrade is not 'officially' out yet but expect it next month. For now what we have seen is numbers in the 6XX wheel range and here is a preview of the real world capability. BimmerBoost member @pr3ci5n335i in the video below runs his E90 automatic 335i against a 2014 Nissan GTR on E85 with full bolt ons. The 335i is at roughly 25 psi of boost and also has full bolt ons in addition to the Pure Turbos Stage 2 N54 turbo upgrade. He also has the TFT inlets and his fuel in the video is an E50 blend with meth injection. The 335i takes the hit here but steadily pulls the GTR until it shuts down. Definitely an impressive result considering what bolt on GTR's on E85 are capable of. 2010 E90 M 335i: Alpina AT, FBO (VRSF 5" Stepped FMIC, Catless with BMW PE, TFT upper and lower chargepipes, HKS BOV, BMS 2 gallon Meth kit, Stage 1 Walbro 255 inline LPFP, BMS low temperature thermostat bypass), JB4 map 3 80add, BMS E85 Flash using MHD, Pure S2 turbos, APEX Arc-8, no rear seats

    You often hear about ball bearing and journal bearing turbos. What is the difference? The ball bearing setup consists a single sleeve system that contains a set of angular contact ball bearings on either end, whereas the traditional bearing system contains a set of journal bearings and a thrust bearing. The bearings can affect response as well as longevity. How about a simple demonstration to get illustrate the point?

    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!

    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

    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 new Ford GT is going to be a very limited car. Ford already stated production would be under 1000 units. The price is expected to be in the mid 400,000 range if not higher. If those factors do not deter you from a purchase Ford is also requiring potential buyers to apply for purchase consideration. That means even if you have the money you may not get one. This information all comes from a Reddit user who claims to work at Ford. So far, Ford has not refuted any of this info and rumor is they even have confirmed it: • Ford will introduce a unique ordering process for the all-new Ford GT supercar, with the program commencing in early 2016. • Ford GTs will be assigned based on a customer application process, offering a personalized experience for every Ford GT buyer. • Anyone can apply; priority will be given to loyal Ford customers including current Ford GT owners. • Applicants selected through the process will be assigned a car by Ford and complete their purchase through a Ford GT certified dealership of their choice. Part of this is to deter people from flipping the car for a quick buck. It is going to be in very high demand and if the previous GT is anything to go by it will only appreciate in value. Now to find $450k lying around somewhere... Source

    Jonny Lieberman works for MotorTrend and you probably have seen him in the Head 2 Head episodes. BimmerBoost has nothing against him although we wonder how someone gets a job with MotorTrend when they make basic mistakes. Lieberman's job is to know about the cars he is talking about. Which is why BimmerBoost made it a point to explain that in the latest Head 2 Head where he states the ATS-V is more powerful than the F80 M3 because the M3 has 'only' 425 horsepower Liberman and MotorTrend are wrong. Very wrong. Absurdly wrong. Embarrassingly wrong. The F80 M3 and the F82 M4 are severely underrated. The car makes much more than its 425 horsepower crank rating. Frankly, it is closer to a wheel horsepower rating than a crank horsepower rating. One should assume this simply by juxtaposing the acceleration figures of the F80 M3 and E90 M3. The difference is not 11 horses. MotorTrend's own test figures prove that. The F80 M3 is insanely underrated. Now we have dyno results showing 427 horsepower to the wheels for the F80 M3. We have stock 1/4 mile times showing 11.9 @ 119. Liberman claims to be aware of the M3 being underrated but when asked for proof provided nothing to support this. Additionally, he does not mention the M3 is underrated in the Head 2 Head video. He states the ATS-V is more powerful. He also on Twitter states his support for this as the ATS-V being quicker despite being heavier. While the ATS-V does indeed get a 12.1 second elapsed time as tested by MotorTrend the F80 M3 gets a 12.3 @ 118.1 miles per hour. The ATS-V hits 12.1 at a slower 116.2. The only thing Lieberman gets right here is that the ATS-V is quicker but it is not faster. Trap speed is primarily a product of power. MotorTrend's own numbers and Lieberman's own statement support BimmerBoost. Point easily proven without even having to show the dyno numbers. Not to mention, the guy should probably know that a RWD car with a ton of torque that traps higher will improve its elapsed time with better traction off the line. That means the M3 with drag radials can be a hell of a lot quicker. Perhaps MotorTrend just doesn't know how to launch as well. Lieberman goes on to state I need to check my facts. The same man who called the new S65 AMG V12 an M275 model despite it being the updated M279 V12 variant from AMG. He conveniently ignores this point. One who does not get their own facts correct should not be telling others to check theirs. Lieberman and MotorTrend need to check their own facts. Rather than lobbing insults for getting called on their mistakes, they should correct them. There is no shame in being wrong. There is a bit of shame in a 'kid' knowing the facts better than the professional though, right? Lieberman, if you ever want to engage in a debate with me feel free. Based on what I have seen so far it will be one-sided. Whenever you want to, I'm right here. MotorTrend, when you are ready to hire someone who checks their facts, let me know.

    The newer AMG's are making a lot of torque by virtue of their turbo powerplants especially when upgraded. Weistec themselves is producing several turbo upgrades for the new AMG motors which means huge power and torque figures. Those figures are big enough to easily exceed the capacity of the stock 722.9 transmission. The solution is the Bulletproof 722.9 upgrade from Weistec. Speaking to Weistec we learned this transmission upgrade has held whatever they have thrown it. That means it will hold whatever you throw at it and then some. Here are the details on the package: Complete Package Increased Torque Capacity Weistec Performance Clutch Material Increased Number of Discs per Clutch Pack Redesigned Clutch Piston Geometry Increased Frictional Surface Area Increased Clutch Material New OEM Gaskets and Seals New OEM Fasteners and Hardware It is important to note this is a complete hardware package as stated in the very first bullet point. Why is this important? Because Weistec can ship the complete hardware to anyone and they can do the install themselves. Owners no longer need to try to figure out how to get their transmission to Southern California. No doubt AMG enthusiasts across the globe will appreciate this. More surface area and more discs means more torque capability. This is the 722.9 taken to the maximum. Fitting more discs to somehow try to get more surface area beyond this will not be possible. The clutch material itself underwent testing for the past two years. BenzBoost members such as @MR747 have gone mid 10's with this upgrade at over 130 miles per hour in the 1/4 mile. To be noted, this amounted to an improvement of 4/10's and 6 miles per hour on what he did before the transmission upgrade was installed. Weistec themselves has gone over 170 in the 1/2 mile with this upgrade in their M157 turbo upgraded W212 E63 AMG S. The torque capability is clearly there but in addition the shifts are firmed up. The new clutch material offers greater resistance to heat (less slippage when warm say after a burnout) and obviously generates greater friction than the factory material. The clutch material offering better heat resistance is one part of keeping the transmission cooler along with the new transmission pan. The new pan allows for a greater volume of fluid. Here are the specs: Fluid Capacity Increased by 2.5 Quarts Integrated Cooling Fins Internal Anti-slosh Baffling O-Ring Seal Two -8 ports for Additional Transmission Cooler Circuit (Additional Cooler not included) Drain and Fill Plugs Two Transmission Pan Magnets Mounting Hardware Included You will want to combine the Weistec clutch hardware with the upgraded pan for the ultimate 722.9 upgrade. Should one desire to go beyond this the upgraded Weistec 722.9 pan features two -8 ports for an additional transmission fluid cooler. It seems they thought of everything. Speaking with Weistec they assured BenzBoost this truly is a Bulletproof upgrade and not just in the name alone. They have tested it thoroughly, engineered it to take maximum abuse, and have yet to have the upgrade fail. It is nice to see solutions of this caliber available in the AMG world. Oh, and take note, this applies to all the new 722.9 cars as well including the W205 generation along with the past cars including the 4Matic variants. Well done yet again Weistec. 722.9 Bulletproof Package retails for $3649.99: http://weistec.com/722-9-bulletproof-build-package-mct-awd.html 722.9 Transmission Pan retails for $599.99: http://weistec.com/722-9-transmission-pan.html

    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.
