    Just the other day a new N54 horsepower record was announced. Some confusion arose as to what turbo kit, what modifications, and whose tuning was employed on the car. The owner of the car came on BimmerBoost to share the details of his build. What better source for details than him? Congratulations to @jputtho2 and we appreciate his additional insight below: First off, I owe HUGE thanks to Jake and the guys at Motiv Motorsports with all of their help with pointers on the tuning side of this and the very high quality products they offer. Also Huge thanks to Chad and Ryan Modified by KC who did the install and tuning on my car. Mike and Aaron and the guys at FFTEC for a very well made turbo kit, and last but not least Steve at Fuel-It taking care of me and my last minute change to the Stg 3+ lpfp! I wouldn't have been able to do this with my life's schedule being so busy with my rapidly growing business and my family. Anyone that knows me knows I'm extremely anal about my cars and in fact was the first time in 10 years that I have trusted someone to work on my cars other than myself. (My cars prior I did all of the assembly, fab work, tuning, etc). This setup is fairly simple as far as mods go and can be replicated easily now that there is a growing support in this community of quality vendors such as the ones I listed above. It's a 100% stock unopened 64k mile long block. It's what I consider a bolt on car. Still has every single creature comfort as one that came from the factory minus the windshield washer reservoir. Well the reservoir is still there the full neck is removed but A/C, heat, cruise, Nav, etc, etc, is still all there and functional. Fuel was 100% e85. To be exact it was e70 winter blend from the pumps that I blended e98 in to bring it up to ~e82. The pumps here should be switching to the summer blend e85 here in a month or so. Injector duty cycle on the port injection was 80% and I can't remember exactly what the DC was for the direct injection but it was roughly the same. I would say its safe to assume 900whp on 100% e85 with this fuel system isn't an issue. MODS: - FFTEC twin scroll Top Mount Precision billet dbb 6466 T4 1.0ar divided, twin Tial MVS WG's - Motiv Motorsports PI-1000 kit - Fuel-It "Hulk"Stg. 3+ lpfp - Cobb AP (Controls the DME/DI) - Haltech Platinum Sport 1000 (controls the PI and boost) - Custom harnesses made by Chad at Modified by KC - Clutchmasters FX850 twin disc - VRSF 7" IC - VRSF charge pipe - Tial Q bov - 4" to dual 3" exhaust The final number was 861whp at 250-255KPA or a peak of 36psi. We were having interference on the rpm pick up for the dyno so I'll post two graphs, one over vehicle speed and the other with engine speed but the engine speed is going to be pretty erratic due to the interference on the pick-up and lost signal. Exact TQ is unknown on the 800+ pulls because of this. It's around 750-760wtq which is low because we had to ramp boost in to keep torque lower due to a "Too Much Torque" limp mode if we gave it all right away on basically anything over 775whp. Otherwise, following what it was was making for tq I would guess it would be around 800wtq and spool would have been about 300-500rpm quicker. The car has A LOT more left in it and this number can easily be broken. My goal today was to make big power but also be able to enjoy after the dyno. I plan on pushing it again this winter until I run out of turbo or the motor lets go and then it'll be a fully forged bottom end, possibly a Motec m142 to simplify the tuning side, and try and do something with the head to make it more rev happy because it really could use another 500-1000rpm. I wouldn't be surprised if the n54 could handle 900-915whp stock. For how long though is the question. I didn't want to be the test mule for the limits of the motor right now. Anyway, we made I think 75-80 pulls on e85 alone, half of those were well over 700whp and I think 5 pulls over 800whp (805, 813, 832, 858, 861). Pull after pull it just wanted more and never showed any signs of slowing up. Here is the 861whp and 832whp graph over vehicle speed. We did make an 858whp pull but the boost control was unhappy bouncing all over hitting target then falling on it's face. This is the 861whp graph with tq reading over engine speed and also showing the dyno losing signal because of the RF interference with the pick-up lead. And then same graph over vehicle speed showing the erratic tq readings again from the reason above. Here is the video of the 861whp pull. (excuse the mismatched wheels, I have new DPE wheels that I was waiting till after the dyno to put on)

    The 'professionals' at MotorTrend often amuse this network with their work. For a big name that has been doing this for decades it is mind boggling how the magazine simply can not understand that crank ratings do not mean much of anything. Seriously, does anyone think the S55 engine the F80 M3 and F82 M4 is actually putting out 425 horsepower? It takes just a basic google search to get a dyno of the new M car and see its output at the wheels exceeds the crank HP rating on a Dynojet. We are seeing many high performance cars underrated and BMW has routinely been doing this with their turbo motors. So why does this fly over the heads of the geniuses at MotorTrend? "At 464 hp, the ATS-V has 39 hp and 38 lb-ft on the BMW M3 and M4, which make 425 hp and 406 lb-ft from a twin-turbo 3.0-liter I-6." There is no doubt the ATS-V is putting out 464 horsepower and 444 lb-ft of torque. The thing is, the F80 M3 is also matching that output and then some. Shouldn't a publication like MotorTrend understand their statement based on paper figures is misleading and uninformed? It's hard for enthusiasts to take the big publications seriously when they make basic mistakes and comparisons like this that do not delve even slightly beyond the superficial. I suppose that says something about the writer and the target audience. P.S. This was the power rating Cadillac claimed at the LA Auto Show for the ATS-V: Source

    This is not the first time we have seen something like this. Anyone remember the marketing material for the E82 BMW 1M showing it driving around with the E30 M3? This got people saying the 1M was a return to the BMW driver's car producing fun and cheap lightweight models. This despite the fact the E30 M3 has absolutely nothing in common with the E82 1M and it will also have nothing in common with the F87 M2. This is what BMW head of design Adrian van Hooydonk stated, "The E30 M3 has a really big fan base, and we are going to be taking cues from it for a future product." Not really saying much there, now is he? Perhaps he will incorporate something from a styling standpoint that serves as some kind of homage or link to the original E30 M3. From an actual M car standpoint the M2 and 1M are nothing like the E30 M3. The cars are not built for DTM homologation purposes. They do not have naturally aspirated motors. They do not have four-cylinder high revving naturally aspirated M motors designed for racing. In the case of the 1M that particular car does not even have an M motor under hood. Once you factor in the weight difference between the E82 1M at 3339 pounds and E30 M3 at 2857 pounds and that the original was actually built for DTM competition you realize this is nothing more than marketing speak. The 2016 F87 M2 is expected to come with a tweaked N55 engine offering 370 horsepower and likely will have a DCT option. Considering the F22 M235i weighs 3494 pounds do not expect some new E30 M3. It won't even be a new E46 M3. Expect an M235i with some minor tweaks. Just like how the 1M was a 135i with some minor tweaks (and no M motor). Bringing up the E30 M3 is just marketing speak. Nothing more, nothing less. Source

    Lets hear some opinions: Been lightly modifying cars since 2001 (GTI, '04 STI and now 08' 335xi) have done some fair amount of wrenching, but nothing major. But nothing will remain stock in my garage. Here are my considerations: 1. Used GTR (goal is under $50k in 1-2 years from now). Will do e85 conversion w/full exhaust. Pros - Dream car, fast, visceral. Cons - Cost of ownership insane, even if you do your own work. One mechanical failure away from a $10,000 repair bill. Automatic transmission as good as it is, I fear will undermine the fun of driving it. 2. Used 996TT (goal under $40k in 1-2 years from now). Will modify, even consider turbo-upgrade. Pros - Lower cost of ownership, fast, manual transmission, (reliable, don't laugh, its supposedly true!) Cons - Don't really care for 911s. Will be a 12+ year old car for $40k+. No trunk. 3. Near new BRZ/FRS w/turbokit Pros - Cheap, fast w/turbo kit, two major tuners are within 50 miles of me (Full Blown and MAP), lowest cost of ownership. Cons - RWD only, seriously deviating from the stock setup 4. Keep my 08' 335xi (65k miles, well maintained, no issues) and upgrade to RB or VTT w/intake. Pros - Paid off, has spec 2+ clutch + full bolt ons w/meth, very familiar with platform. Comfort. Cons - AWD system is sub-par (not performance), have owned for 4 years.

    The BMW and Toyota technology sharing agreement has been a bit confusing its application. We know Toyota and BMW agreed to partner up on certain things and share technology back in 2013. Since then there has been a lot of speculation on what this agreement would bring. That speculation has been all over the place. MotorTrend stated the cars would have carbon technology from the 'i' series and be very small and expensive hybrids with the BMW version coming in at around $70,000. Car Magazine then reported we would get mid-engine hybrid sports car with $100k price tags to take on the 911. Maybe they were just pulling things out of thin air to sell magazines, who knows. Now Autocar who is not exactly a bastion of solid automotive reporting states the partnership will spawn two all wheel drive hybrid sports cars that are different sizes targeting different demographics. This is supposed to result in a next generation Z4 as well as a Toyota Supra revival. BMW's Ian Robertson stated, “The one thing we’re clear on now is that a platform for both companies can work. The cars in themselves don’t actually need to be positioned the same. The platform can spawn two positionings. The concept works, the platform can deliver and now we have two proud sets of engineers - one group German, one group Japanese - who are each fighting and arguing for the car they want.” That is about all we have to go on. That the platform can be used to create two cars that are different enough from each other to not simply be the same car with a Toyota or BMW badge being the main point of differentiation. Beyond that everything is still speculation and who knows what the result will be. We only know they are still working on it and that hybrid technology is a certainty. Source

    Where are the 4.0 TFSI V8 turbocharger upgrades? We do have an AudiBoost member who has upgraded the turbos on his RS7 with a pair of Garrett GTX28's and has received custom tuning from APR to make it work. But even APR themselves does not offer a turbo upgrade and why are they doing custom turbo tuning work overseas but not at home? So what gives? Well not everyone has the deep pockets of that particular member (@Ghost.) but there is still a noticeable absence of 4.0 TFSI upgrades even for the stock housings let alone going to bigger turbos. Is he running an aftermarket ECU to make it work? Loba Motorsport teased this picture of their 4.0 TFSI turbo upgrade as coming soon... back in 2013. Well it isn't here yet so once again, what gives? Perhaps the tuning ability is overstated on the stock DME. Guys are raising boost and so forth but control seems to still be in its infancy or wouldn't turbocharger upgrades be all over the place? The BMW S63TU also does not yet have any successfully running turbo upgrades but they are expected to come now as the ECU has recently been cracked. Why the 4.0 TFSI still does not have anything available despite hardware having already been developed remains a mystery.

    Well, they made good on their promise. In October of last year Extreme Turbo Systems announced that they intended to take back the Nissan GTR 1/4 mile world record. AMS Performance in that same month set the Nissan GTR record with a pass of 7.70 @ 186.51. Well the quickest and fastest GTR is now 7.492 @ 189.20. Just under 190 miles per hour and likely indicating we will have GTR's trapping 200 in the 1/4 mile in the near future. That is hard to even process as its unbelievable performance. It was just a matter of time for this to happen as ETS was already getting close. Early this year they ran 7.75 @ 176.36 but technical issues hindered them. It's safe to say it looks like they solved the problem. Expect more details to come along with a video. The specifications should be similar to when the car cracked 2000 whp and would have even shown more had the dyno been able to read the output past that mark. *Edit* Video added:

    The CTS-V is an awesome performance sedan. In stock form it will do over 200 miles per hour, it has 640 horsepower from an LT4 supercharged V8 borrowed from the C7 Z06, and it is a reasonable value in comparison to the German performance sedans if it comes in at its expected $75,000 price point. Now the previous generation CTS-V was produced as a wagon by Cadillac. This time around it looks like they are not going to do it. Bummer. It almost would make would make hauling kids and groceries not seem like a chore.

    That is the rumor going around. We have no official source on this but apparently there was some Audi employee meeting in the USA and the RS3 was confirmed for the USA at that meeting. It is really no surprise as we always expected to get the sedan. The hatchback we knew was out of the question based on precedent. Audi already sells an RS3 Sportback in Europe based on the 8V platform. So, expect that same drivetrain to make its way into the 8V A3 sedan. That means a 367 horsepower and 343 lb-ft of torque 2.5 liter turbocharged and direct injected inline-5 sending its power to all four wheels courtesy of a 7-speed dual clutch transmission. Now the 2.5 TFSI motor can put out a heck of a lot more power than that. Remember the 525 horsepower A3 Clubsport concept car from last year? That is what the RS3 should be but it would eat everything else in the Audi lineup alive. That's ok, that is what tuning is for. The most obvious competition for this car would be from the Mercedes CLA45 AMG. The RS3 should be able to out-muscle it though. Whatever happened to Audi's high output EA888 that was supposed to go in the RS3 anyway? Hopefully we can get more concrete details and not just some rumor someone supposedly overheard somewhere. The chances of an RS3 in the US are the best they have ever been though. The sedan seems like a certainty.

    Not much can play with a BMW S1000RR in stock form. The bike is flat out absurdly fast. When tuned? Well, it takes something pretty damn special to run it. An 1100+ horsepower Boost Logic Nissan GTR may just qualify as something up to the task. The thing is though these two S1000RR's in the video are tuned. The camera bike has a Brentuning ECU tune in addition to a full Akrapovic exhaust system. The other S1000RR just features a full exhaust and a PCV (Power Commander V). The Brentuning ECU tune makes a large difference as the camera bike destroys the other S1000RR and the GTR. They do three runs and in all three it pulls pretty hard. Thank you to BimmerBoost member @Czero for the video.

    The S54 remains the BMW inline-6 power king going into 2015. Well, the S38 may have something to say about that but that is a discussion for another day. Sound Performance built the E46 M3 S54 motor and Saad Racing provided a turbo kit utilizing a Precision 6766 turbocharger. The result? 859 wheel horsepower pushing 29 psi of boost on a Mustang Dyno. Here are the numbers at the various boost levels tested: 678whp @ 18psi 740whp 624wtq @ 23psi 859whp 710wtq @ 29psi On a Dynojet this should be breaking 900 whp. They of course also have 1000+ whp M3's but this shows what is possible with a Precision 6766, a ProEFI 128 ECU, and a built motor. Specs: SP Built 10:1 CR Engine Saad Racing Turbo Kit w/ SP 3" Boost Activated Exhaust Cutout Saad Racing E85 Fuel System Saad Racing Intake Manifold w/ LS3 DBW Throttle Body SP Direct-Port Nitrous Kit ProEFI Pro128 Flex Fuel Standalone EMS OS Giken Twin Disc Clutch They plan to test the Precision 6870 CEA GEN2 turbocharger next. 9XX whp on the Mustang? We will have to wait and see.

    Just yesterday AudiBoost posted an article wondering where the 4.0 TFSI V8 upgrades are at. Well, there may be some good news on that front as AMS Performance intends to get into the Audi tuning game. You may recall that they are working on upgraded turbos for the BMW S63TU V8 engine platform and already offer upgraded turbos for the AMG M157 V8. That leaves the Audi 4.0 TFSI V8 as the odd one out but hopefully for not too much longer. AMS products are coming along with a turbo upgrade although there is no timetable for the latter: AMS Eric: "Right now we are working on our boost cooling kit for the S6. It's still a ways out as we are still testing the prototype. Following that we will test our upgraded turbos. Our downpipes are done and test fit and I should have those ready to go by the end of march or earlier. Turbo upgrades are in process but I dont see the tune necessary for them ready until early summer." Tuning will be done by Tony of EPL (European Performance Labs) and it will be interesting to see if he can pull it off. It will also be interesting to see if AMS offers turbos upgrades for the entire 4.0 TFSI V8 line or just certain models. In theory the turbos should fit any 4.0 TFSI V8 which would turn the S6/S7 into an incredible tuning value compares to the RS6/RS7. We'll see what develops.
