    BimmerBoost often criticizes BMW engine swaps but those swaps criticized do not utilize BMW powerplants. This one on the other hand does and the result is absolutely awesome. Who needs to stick yet another LS V8 under the hood of a BMW when the S63 4.4 liter twin turbo V8 exists? It seems this Russian owner agrees as he built one of the most amazing swaps BimmerBoost has ever written about. An S63 V8 under the hood of this 1-Series alone would be incredible but on top of that this E82 1M gets an all wheel drive system. Will that add considerable weight? Sure, but it will also help put down the immense torque the S63 V8 is known for especially in tuned form. Now the exact details are somewhat difficult to come by as Google Translate is not a professional translator. It seems this project originally started as an E82 1-Series which received a S65 V8 swap from an E92 M3. Since then the bodywork was converted to a 1M and painted yellow. Then the S63 V8 (the motor and transmission was taken from an E70 X5M) was swapped in. Enjoy the build photos below and hopefully we get more information on this car. <blockquote class="instagram-media" data-instgrm-version="7" 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% 0; text-align:center; width:100%;"> <div style=" background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACwAAAAsCAMAAAApWqozAAAABGdBTUEAALGPC/xhBQAAAAFzUkdCAK7OHOkAAAAMUExURczMzPf399fX1+bm5mzY9AMAAADiSURBVDjLvZXbEsMgCES5/P8/t9FuRVCRmU73JWlzosgSIIZURCjo/ad+EQJJB4Hv8BFt+IDpQoCx1wjOSBFhh2XssxEIYn3ulI/6MNReE07UIWJEv8UEOWDS88LY97kqyTliJKKtuYBbruAyVh5wOHiXmpi5we58Ek028czwyuQdLKPG1Bkb4NnM+VeAnfHqn1k4+GPT6uGQcvu2h2OVuIf/gWUFyy8OWEpdyZSa3aVCqpVoVvzZZ2VTnn2wU8qzVjDDetO90GSy9mVLqtgYSy231MxrY6I2gGqjrTY0L8fxCxfCBbhWrsYYAAAAAElFTkSuQmCC); display:block; height:44px; margin:0 auto -44px; position:relative; top:-22px; width:44px;"></div></div><p style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; line-height:17px; margin-bottom:0; margin-top:8px; overflow:hidden; padding:8px 0 7px; text-align:center; text-overflow:ellipsis; white-space:nowrap;"><a href="https://www.instagram.com/p/BJqfUBKjzQD/" style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px; text-decoration:none;" target="_blank">A video posted by Sheff140 (@sheff140)</a> on <time style=" font-family:Arial,sans-serif; font-size:14px; line-height:17px;" datetime="2016-08-28T19:20:31+00:00">Aug 28, 2016 at 12:20pm PDT</time></p></div></blockquote> <script async defer src="//platform.instagram.com/en_US/embeds.js"></script> <blockquote class="instagram-media" data-instgrm-version="7" 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:28.125% 0; text-align:center; width:100%;"> <div style=" background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACwAAAAsCAMAAAApWqozAAAABGdBTUEAALGPC/xhBQAAAAFzUkdCAK7OHOkAAAAMUExURczMzPf399fX1+bm5mzY9AMAAADiSURBVDjLvZXbEsMgCES5/P8/t9FuRVCRmU73JWlzosgSIIZURCjo/ad+EQJJB4Hv8BFt+IDpQoCx1wjOSBFhh2XssxEIYn3ulI/6MNReE07UIWJEv8UEOWDS88LY97kqyTliJKKtuYBbruAyVh5wOHiXmpi5we58Ek028czwyuQdLKPG1Bkb4NnM+VeAnfHqn1k4+GPT6uGQcvu2h2OVuIf/gWUFyy8OWEpdyZSa3aVCqpVoVvzZZ2VTnn2wU8qzVjDDetO90GSy9mVLqtgYSy231MxrY6I2gGqjrTY0L8fxCxfCBbhWrsYYAAAAAElFTkSuQmCC); display:block; height:44px; margin:0 auto -44px; position:relative; top:-22px; width:44px;"></div></div><p style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; line-height:17px; margin-bottom:0; margin-top:8px; overflow:hidden; padding:8px 0 7px; text-align:center; text-overflow:ellipsis; white-space:nowrap;"><a href="https://www.instagram.com/p/BJSlbAhjsgE/" style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px; text-decoration:none;" target="_blank">A video posted by Sheff140 (@sheff140)</a> on <time style=" font-family:Arial,sans-serif; font-size:14px; line-height:17px;" datetime="2016-08-19T12:32:07+00:00">Aug 19, 2016 at 5:32am PDT</time></p></div></blockquote> <script async defer src="//platform.instagram.com/en_US/embeds.js"></script>

    $134,200 for a performance car with an emphasis on track performance better result in impressive track performance. The M4 GTS makes a big statement with its MSRP but does not back it up where it matters. As a matter of fact, the Ford Mustang GT350R and the Chevrolet Camaro SS 1LE both top it around Laguna Seca. This measured result is from MotorTrend's own testing. The M4 GTS laps Laguna Seca in 1:37.66. The Shelby Mustang GT350R is 1.6 seconds quicker. That is an eternity. It's long enough to do the math as to how much money someone buying a Shelby GT350R at $62,070 saved over an M4 GTS. What makes this truly spectacular is not only is the Mustang half the price it has a naturally aspirated high revving engine. Ford is beating BMW at their own game with a hand tied behind their back. Honestly, as a BMW M fan forced to sit back and watch the as M division chokes from spending so much time sniffing their own farts this is highly satisfying. Is it a wake up call to BMW? It should be considering that not only did the M4 GTS get obliterated by the Shelby GT350R the $44k Camaro SS 1LE edged the M4 GTS as well. What is the 1LE? Just an option package for the Camaro: Camaro SS 1LE Highlights 6.2L LT1 V8 rated at 455 horsepower, and 6-speed manual transmission (automatic transmission not available) Magnetic Ride Control Segment-exclusive electronic limited-slip differential with 3.73 ratio Unique forged-aluminum wheels with 285/30ZR20 front tires and 305/30ZR20 rear tires Goodyear Eagle F1 Supercar tires with a compound and construction developed exclusively for Camaro Brembo brakes with new 6-piston monobloc front red calipers and 2-piece rotors Track cooling package with engine oil, differential and transmission coolers Suede steering wheel with shorter-throw shifter Dual-mode exhaust system RECARO front seats with aggressive bolsters optimized for shifting and steering comfort Satin black hood, front mirrors and unique 3-piece rear spoiler Available Performance Data Recorder What is the point of a $135k+ M car built for the track that can not top anyone in its price range let alone cars at a fraction of the cost? The M4 GTS does not need to be a world beater (like the cheaper Viper ACR) but it needs to be better than this to be taken seriously. Does anyone even take the M division seriously anymore? We will have the full results when MotorTrend posts their 2016 Best Driver's Car videos but it's clear that not only does the M4 GTS not live up to the hype, it's an abject failure.

    The problem with dyno records is that different dynos read differently. For this reason the Dynojet has become a sort of standard for power records. Now, is this technically an N54 stock turbo power record? Yes. Was it achieved on a Dynojet? No. Will the numbers change on a Dynojet? Yes. They could go up or down but based on previous Dynocom results seen it is more likely to see them go down. Regardless, stock turbo records do not mean much in an N54 tuning era where people are trying to hit 1000 what the wheels. It still is of course impressive to see this kind of power from the stock N54 turbochargers and how far stock turbo tuning evolved. Congrats to BimmerBoost member @hydra on the numbers but a Dynojet for context would be great to truly be able to claim a record. Impressive output nonetheless. Mods: AFe Momentum GT N54 intake MMP stock location inlets Wagner Evo2 Competition FMIC Custom-made Chargepipe incorporating a single Evo X metal BOV Generic catless DPs Magnaflow full exhaust system with catless midpipes Stock LPFP fuel pump Stock TMAP sensor Stock outlets and no meth kit Car has just under 38k miles on it and is running 100% stock, never touched, never removed turbos... Running 80-something % WGDC at 6500rpm... Running 116+ octane gas and plenty of timing

    This is a great comparison to really see how cars perform. This is not mixing and matching Nurburgring laptimes from different days with different drivers and cars set up differently from their production counterparts. What we have here is as close as we can get to an honest track comparison from the major publications. What do we learn? That the BMW F82 M4 GTS again is beaten soundly by the Mustang GT350R. Honestly, enough about the overrated M4 GTS. The Mustang GT350R is a better driver's car even for the same money. At less than half the price it is not even a discussion. What else do we learn? That the Viper ACR is the baddest car on the planet. Seriously, Ferrari can pack their crap up and go home. That the brand spanking new twin turbo 488 GTB is trounced by the Viper that Ferrari actively holds back is poetic justice. The Viper ACR delivers a giant American middle finger pointed directly in the direction of Fiorano. Suck it Ferrari. Anything else? Well, the Camaro SS 1LE is soundly beaten by the BMW GTS showing the GTS on a big track like VIR (Virginia International Raceway) can simply use its power to make up for its other deficiencies. The main disappointments though are the Lexus GS-F and Audi R8 V10 Plus. 3771 pounds for the R8? Ouch. It gains quite a bit of weight over its Huracan sibling. It also is beaten by the cheaper Camaro SS and Porsche Cayman GT4. The Lexus GS-F brings up the rear (but ahead of the Audi TTS) because that is exactly where it should be and where it deserves to be. The standout other than the Viper ACR is really the Corvette Grand Sport. To be a tenth of a second off the Porsche 991 GT3 RS is incredible. Honestly, it is highly commendable. GM deserves a ton of credit for packing so much performance per dollar into the Corvette. Porsche even with all their fancy technology and a car at more than double the price can not pull ahead. Time for a GT2? Here is the full list of laptimes and the historical comparison although many of the previous laps are before a repaving of VIR so this is not exactly apples to apples. Videos of the laps and a list of vehicle weights from lightest to heaviest are below. Lap Times: 2:44.2 2016 Dodge Viper ACR 2:45.1 2016 Ferrari 488 GTB 2:47.0 2016 Porsche 911 GT3 RS 2:47.1 2017 Corvette Grand Sport 2:47.4 2016 McLaren 570S 2:50.2 2017 Acura NSX 2:51.8 2016 Mustang GT350R 2:52.9 2017 BMW //M4 GTS 2:54.0 2016 Porsche Cayman GT4 2:54.8 2017 Chevrolet Camaro V8 1LE 2:56.1 2017 Audi R8 V10 Plus 3:01.9 2016 BMW //M2 3:03.5 2016 Dodge Charger Hellcat 3:03.9 2016 Focus RS 3:04.0 2017 Chevrolet Camaro V6 1LE 3:05.9 2016 Lexus GS-F 3:07.7 2016 Audi TTS Curb Weights (pounds): Porsche Cayman GT4 - 3058 Porsche 911 GT3 RS - 3155 McLaren 570S - 3189 Audi TTS - 3223 Viper ACR - 3400 Ferrari 488 GTB - 3428 Chevrolet Corvette Grand Sport - 3445 Ford Focus RS - 3451 BMW F87 M2 - 3455 Chevrolet Camaro 1LE - 3516 BMW F82 M4 GTS - 3538 Ford Mustang GT350R - 3718 Chevrolet Camaro SS 1LE - 3743 Jaguar Project 7 - 3766 Audi R8 V10 Plus - 3771 Acura NSX - 3854 Lexus GS-F - 4132 Dodge Charger Hellcat - 4564 Tesla Model S P85D - 5010 Historical Data: Videos:

    Well, the F80 M3 is in the 10's on the factory turbochargers. This car has bolt on modifications and Toyo R888 rubber. Thanks to a solid 1.656 60 foot the car broke into the 10's in the 1/4 mile running 10.900 @ 125.34 miles per hour. Another pass on a slightly worse 1.670 60 foot resulted in a 10.982 @ 128.25. What is the mod list? FBO (full bolt on) + Methanol AWE heat exchanger E30 fuel BMS JB4 Toyo R888 Evolution of Speed intercooler Nothing crazy there just typical bolt ons for the BMW turbo world. It was obvious the F80 M3 and F82 M4 could run 10's it was just a matter of someone launching well enough to get there. Congrats to Mike_f80nyc and well done.

    So far there is only this teaser photo to go on but it's a hell of a teaser. This is a top mount single turbo E92 M3 S65 V8. The fabrication work was done by JC Fabworks. This is the first and only top mount single turbo S65 V8 that exists and Gintani told BimmerBoost a top mount single turbo setup could not be done. Gintani is the only other tuner bringing an S65 V8 turbo kit to market but their setup is a more traditional bottom mount twin turbo design. It has also been in development forever and still is not on the market. BimmerBoost sampled the Gintani twin turbo setup way back in 2014 and it is supposed to go on the BimmerBoost.com project M3. It is great to see competition and another option on the market. There are many question marks however such as pricing, power, tuning, etc. How much boost? What turbo? What fuel? Who is tuning it? What is the cost? When will it be available? A teaser photo does not answer these questions. Formula Autohaus states this kit will be available for sale through their Las Vegas location. We await further details but congratulate them on doing what many said was impossible.

    There is no stopping the Viper ACR. It is a track animal bent on destroying whatever dares come across its path. The M4 GTS? The Shelby GT350R? The Porsche 911 Carrera S? The new Acura NSX? The McLaren 570S? All simply lambs led to the slaughter. Emphasis on slaughter. Just look at what the Viper ACR did around Laguna Seca in the hands on Randy Pobst: 1. Dodge Viper ACR - 1:31.58 2. Audi R8 V10 Plus - 1:34.23 3. McLaren 570S - 1:34.58 4. Mercedes-AMG GT S - 1:35.30 5. Ford Mustang Shelby GT350R - 1:36.11 6. Acura NSX - 1:36.36 7. Porsche 911 Carrera S - 1:36.44 8. Nissan GT-R - 1:37.08 9. BMW M4 GTS - 1:37.66 10. Chevrolet Camaro SS 1LE - 1:37.78 11. Jaguar F-Type SVR - 1:38.75 12. Aston Martin V12 Vantage S - 1:41.77 It is almost a full three seconds faster than the next car up which is the Audi R8 V10 Plus. That is a beatdown. The Viper ACR is just on another level and it's amazing this car does not get more respect. Now, it is interesting to contrast MotorTrend's results at Laguna Seca to Car and Driver's results at VIR (Virginia International Raceway). The R8 V10 showed very weakly in Car and Driver's hands yet it is the second quickest car here with Randy Pobst at the wheel. When we say Car and Driver's hands we mean their staff who simply is not on Randy's level when it comes to driving prowess. Car and Driver's Lightning Lap is a good comparison but it is not as scientific as MotorTrend's (which also isn't perfect) due to taking place on multiple days with multiple drivers. MotorTrend uses Pobst at Laguna Seca with the cars running on the same day. That is a big difference. As is the fact VIR rewards power in the lap time more than the shorter and tighter Laguna Seca. What do we learn? That the M4 GTS get its ass handed to it by the Mustang GT350R yet again. It loses at VIR, it loses at Laguna Seca, and it is simply safe to say the GT350R is the superior track performer anywhere. Yes, at a fraction of the price. When you bring the M4 GTS asking price into the argument the car looks like a joke. Is its laptime respectable? Sure, if beating a Camaro SS that comes in at less than 1/3 of the money by a tenth of a second is respectable. The AMG GT S is cheaper, the 911 Carrera S is cheaper, the Nissan GT-R is cheaper, the Mustang GT350R is cheaper, and the Viper ACR is cheaper. What do they all have in common? They are all better performance cars than the M4 GTS. The Mercedes-AMG GT S deserves honorable mention beating the stout GT350R as well as the incredible new Porsche 911 Carrera S. Considering the GT S is not even anywhere near as hardcore as the GT model line gets, that is impressive. Enjoy the videos of the laps below with impressions from Pobst. The winner of the competition will be announced shortly. If we were to guess, the Carrera S is the favorite.

    How does almost 800 wheel horsepower sound from a 6 speed manual N54 with VTT GC turbos? Pretty nice, right? VTT hit 765 whp at 29.3 psi of boost but of course you can run less boost pressure. 28.5 psi resulted in 740, 25.4 psi in 693, and 22.8 in 655 to the wheels.

Nissan GT-R - 1:37.08 9. BMW M4 GTS - 1:37.66 10. Chevrolet Camaro SS 1LE - 1:37.78 11. Jaguar F-Type SVR - 1:38.75 12. Aston Martin V12 Vantage S - 1:41.77 It is almost a full three seconds faster than the next car up which is the Audi R8 V10 Plus. That is a beatdown. The Viper ACR is just on another level and it's amazing this car does not get more respect. Now, it is interesting to contrast MotorTrend's results at Laguna Seca to Car and Driver's results at VIR (Virginia International Raceway). The R8 V10 showed very weakly in Car and Driver's hands yet it is the second quickest car here with Randy Pobst at the wheel. When we say Car and Driver's hands we mean their staff who simply is not on Randy's level when it comes to driving prowess. Car and Driver's Lightning Lap is a good comparison but it is not as scientific as MotorTrend's (which also isn't perfect) due to taking place on multiple days with multiple drivers. MotorTrend uses Pobst at Laguna Seca with the cars running on the same day. That is a big difference. As is the fact VIR rewards power in the lap time more than the shorter and tighter Laguna Seca. What do we learn? That the M4 GTS get its ass handed to it by the Mustang GT350R yet again. It loses at VIR, it loses at Laguna Seca, and it is simply safe to say the GT350R is the superior track performer anywhere. Yes, at a fraction of the price. When you bring the M4 GTS asking price into the argument the car looks like a joke. Is its laptime respectable? Sure, if beating a Camaro SS that comes in at less than 1/3 of the money by a tenth of a second is respectable. The AMG GT S is cheaper, the 911 Carrera S is cheaper, the Nissan GT-R is cheaper, the Mustang GT350R is cheaper, and the Viper ACR is cheaper. What do they all have in common? They are all better performance cars than the M4 GTS. The Mercedes-AMG GT S deserves honorable mention beating the stout GT350R as well as the incredible new Porsche 911 Carrera S. Considering the GT S is not even anywhere near as hardcore as the GT model line gets, that is impressive. Enjoy the videos of the laps below with impressions from Pobst. The winner of the competition will be announced shortly. If we were to guess, the Carrera S is the favorite.

    It's been quite a while since the BimmerBoost.com E92 M3 was discussed. Where we last left off the vehicle was making more power and torque than any E9X M3 in the world and setting records. As a quick refresher, the car featured a built 10.0:1 compression motor with a sleeved S65 V8 block and a Vortech YSI blower. Yes, this build has taken years. Through the missteps, mocking, long nights, fabrication, tuning, and records set the S65 engine platform was pushed very far forward despite how uncooperative it is. Let's not forget this car made more torque than anyone else has up to today: And it also set the E9X 1/2 mile record with a 173.07 pass. This angered a lot of people in the community and let's just be honest ESS-Tuning in particular. ESS with their 'record setting' VT3 car at the same event as the BimmerBoost.com M3 could not even get close to its trap speed. At a subsequent event where the BimmerBoost.com M3 did not run ESS and the VT3 owner cheated by backing up as far as possible to get a running start to inflate the trap speed. It took them several manipulated tries like this but finally they eked out a trap speed a mile per hour higher. Yes, they cheated, because that's what it is and that is how these people are. They actually take pride in posting contrived records. This is all being mentioned to show you just how hard the car was pushed and what took place. The stock trans slipped as you can see in the dyno with the Vortech YSI at 18.5 psi of boost. If it held, just do the math. Even with 'only' 554 lb-ft of torque at the wheels well before the torque peak this is still the torque record today on the S65 platform. Do the math for the redline: 8400 rpm x 554 lb-ft / 5252 = 886 wheel horsepower. A conservative 886 mind you as the torque is still rising as the YSI really hit its sweet spot toward redline. It's a real shame we never saw a clean Dynojet run but the fact is nobody else was within 150+ whp of this car. Unfortunately, Dodson at the time did not have the DCT transmission upgrades available it does now and Kris Gagnon at SSP (South Side Performance) screwed this project over delaying it by over a year with his inability to deliver a working product and misleading me while utilizing my transmission as a model to get discs made overseas he could sell and now does sell. Showing this person's true colors will come in another article at a later date. So what happened? We pushed too hard on a platform BMW cut costs on. The fact of the matter is the S65 V8 is a weak design for boost unless tremendously reinforced. BMW loves to tout how light the motor is and how it is lighter than the iron block S54 it replaces despite offering more displacement and being a V8 but the S54 block is not only stronger it is built better. The S65 aluminum-silicon makeup while being light is very weak. Combine this with tight bore spacing, little to no material to work with, and a poor oiling system resulting from cost cutting going from the S85 V10 oiling system to the S65 V8 and you get a cheap, mass produced motor. The goal is quite simply to build it as cheaply as possible while still making it past the warranty period. Ask E9X M3 guys who did not get their bearings replaced and now are paying the price how they feel about BMW engine quality. It's amazing BMW gets away with this. While many things in this motor were upgraded and it handled more than anyone had ever thrown at the S65 we simply went too far because the goal was not to manipulate circumstances to set some bogus records that idiots on forums slurp up but to raise the performance envelope to unforeseen levels. No, it was not a tuning issue. Look at the pictures of motor below. The pistons look practically brand new. The problem was that the main bearings spun: Why? Tons of stress. A Vortech YSI is a monster blower that requires a ton of power to spin. This was not a build with a new crank as the displacement was kept the same. Increasing the boost only exacerbates problems. Things could have been done slightly differently to get it to work but you're always going to be putting more stress on the motor with something like a YSI at high boost than a V3si with low boost. Just the pulley setup alone is completely different and further off the front of the motor which doesn't help reduce various stresses. The other issue is the block flexing. My engine was built quite strong but in order to install sleeves you have to remove material. The idea is the sleeves add material and while the cylinders may be stronger the block as a whole becomes compromised due to how fragile it is to begin with. The block will not be sleeved this time around. Instead, Gintani advocates using a bedplate/brace. AMS does something similar with their GTR builds: AMS uses a billet aluminum piece but Gintani will be using a chromoly piece to brace the block: This should mitigate flex but additionally by switching to turbos stress on the motor is reduced as a whole. It will be possible to make more power at less boost without needing to manually turn a blower. A huge difference in efficiency alone with increased reliability. Furthermore, the factory crank will not be utilized. A new custom forged stroker crank will also take much more abuse than the factory piece: You will notice the stroke is 76.5mm which is a minimal increase over the factory 75.2mm stroke. This is not about displacement gains but simply increased strength and rod to stroke ratio. Technically, yes, it is a stroker build but you will notice those who went big on a stroke increase in the past and tried to add boost ended up with blown motors. That happened for a reason. What else does this build entail? - Mahle pistons - Ferrea intake and exhaust valves - Forged rods - WPC main bearings - BE rod bearings - Two turbos (specs will be provided later) - Welded and machined heads - Dodson build DCT trans - Water/meth - Upgraded fuel system - Carbon driveshaft - Upgraded oiling system - E85 tuning - Gaskets, fluids, etc. When we get to the tuning portion further details will be posted at that time. For now, stock DME tuning is looking likely but the Syvecs S65 standalone may be incorporated. To those who have supported this project and understand the work involved to push a BMW to these levels and that everything does not always go as planned, thank you. To those who have not I'd like to point out not only is BimmerBoost.com bigger than ever before but things will only continue to get better from here on out.

    This is the same BMW F80 M3 that recently broke into the 10's on the factory S55 turbochargers. In case you were wondering what kind of power it took to get there here is the answer. 585 horsepower at the wheels along with over 600 lb-ft of torque at the wheels. It looks like two different maps were tested as on the lower power figure runs the peak torque is substantially higher. Unfortunately, the full graphs are not posted so we can not get a look at the entire curve. Perhaps @Mike_f80nyc can post them. Still, impressive numbers. Especially the torque figures topping over 600 lb-ft at the wheels with a JB4 and methanol on the stock turbos. To BimmerBoost's knowledge, these are the highest power and torque figures from the factory turbos with bolt on modifications.
