      However you feel about methanol injection there is no denying it provides a very nice octane boost. Guys with N54 3.0 liter direct injected twin turbo motors have shown the benefits of meth injection for years now when it is properly installed and maintained of course. The S63TU twin turbo direct injected V8 is showing similar benefits to meth injection as the motor clearly benefits from the octane increase showing 667 horsepower to the wheels. ...

      This is the 2015 F36 4-Series Gran Coupe. BMW basically mimics what they do with the 6-Series Gran Coupe which is stretching the coupe proportions to create a 'four-door coupe' variant. The 4-Series Gran Coupe offers the same 428i and 435i models as the two door 4-Series coupe with turbocharged four cylinder and six cylinder power respectively. The question now is, will BMW offer an M4 Gran Coupe as they offer an M6 Gran Coupe? ...

      Everyone blows motors. Everyone. We have seen blown built motor supercharged S65 V8's from ESS-Tuning among engine failures from just about everyone for a multitude of reasons. That is why it is so important to make sure you have a quality tune on your motor as even if you use stronger aftermarket internals no engine is going to survive a bad tune. What happened here is up to debate and no doubt finger pointing will ensue but it is clear that something happened resulting in a blown motor. ...

      Vargas Turbocharger Technologies has achieved what many said was impossible. The N54 community no longer has to weep over fueling woes as a real HPFP upgrade is finally here. Vargas Turbo Tech delivered on their promise and has forged into new territory on the N54 platform. 100% E85 on upgraded turbos is now possible thanks to the 'Shotgun' HPFP upgrade and the N54 is loving it. The result with the HPFP upgrade from VTT is a new stock frame turbo record at 558 wheel horsepower as the motor finally gets all the E85 it needs. ...

      Here is a good example of parasitic losses and the difference between a centrifugal supercharged power curve and a turbocharged power curve on the same motor. As many of you know Gintani is working hard on its E9X M3 S65 V8 stock DME tuned twin turbo kit and the kit is almost ready to be officially released. Many people will no doubt ask how the twin turbo kit compares to the supercharger kits and now you can see the difference for yourself. ...

      It looks like piggyback tunes are set to rule S63TU performance at least for the short term. This M6 is on the verge of breaking into the 10 second range running two 11 second flat 1/4 mile passes. The car has basic mods consisting of a JB4 tune, catless downpipes, RPI intake scoops, meth injection, and K&N air filters. With just a tiny improvement in the launch it looks like 10 seconds passes for the M6 with bolt ons are well within reach. ...

      It is always fun to see the previous generation M5 and the current M5 go head to head. You have two M5's with completely different engine philosophies here as the E60 M5 of course has the high revving naturally aspirated 5.0 liter S85 V10 and the F10 M5 has the twin turbo 4.4 liter S63TU V8. This is a race we have seen before and the outcome really is dependent on what modifications each car has. That said, the S85 V10 shines from a roll. ...

      An interesting thread popped up on the BimmerBoost BMW Performance Forums last week. The question was raised as to what one would do or what their wish list would be if they had the power to influence decisions at BMW. This led to some humorous responses (which you can read in the comments below) and some generally good ideas. So let's say you are put in charge of BMW with nobody to answer to, what do you do? ...

      The Ferrari FF is an interesting Ferrari to say the least. It has Ferrari's well known naturally aspirated V12 with 6.3 liters of displacement sending 660 horsepower through a seven speed dual clutch gearbox. Where things get a bit different is that this Ferrari has all wheel drive (the first production all wheel drive Ferrari) and it seats four. A four seat all wheel drive Ferrari? The world has seen stranger things come out of Maranello. ...

      The N54 cylinder head is not exactly what one would call BMW's best work and it was never designed with top end power in mind. There is room for improvement in breathing up top and this is a large benefit for N54 owners who switch to a larger turbo such as an aftermarket single turbo conversion. This particular N54 motor has such a single turbo setup and as you can see it benefits up top greatly from the VAC Stage 3 cylinder head. ...

      The entry level German car sector is starting to get a bit boring. Why? Because everyone has the same engine philosophy. All three of these cars feature a 2.0 liter turbocharged and direct injected motor. The Mercedes CLA250 4Matic and Audi A3 2.0 Quattro both offer dual clutch transmissions and both route power to all four wheels. BMW does not offer a dual clutch transmission in the 2-Series (yet) and the 228i is rear wheel drive. ...

      Swedish BimmerBoost member Teddy has a 2007 E91 335d wagon. Teddy's wagon is pure awesomeness. You can follow his build thread here but essentially he added a front mount intercooler, tuned the motor, lowered it, and the result is what you see here. Now since Teddy is from Europe he gets all the cool diesel BMW toys we do not in the United States (no six cylinder diesel wagons for us anymore among other diesels) not to mention that BMW thinks the American market hates wagons. ...

      Two tuned twin turbo German V8's going at it on the highway here. The F13 BMW M6 coupe is the camera car. It features a Stage 2 tune from PP-Performance along with their downpipes and an Akrapovic rear section. The E63 AMG is the 4Matic all wheel drive facelift model and it has a tune from Gorilla racing and aftermarket downpipes. The M6 is lighter by roughly 400 pounds and sends its power to the rear wheels through a dual clutch transmission meaning on paper it has the advantage in this type of race. ...

      Active Autowerke's supercharger kits for the E9X M3 S65 V8 motor are very solid kits paired with solid tuning. As these are kits, you can buy the supercharger from Active Autowerke and have it installed or install it yourself using the supplied tune from Active Autowerke. The tune is designed by default to be safe and accommodate pump fuel for your location. That also means it is one size fits all and not tailored specifically to your car and its modifications (such as an exhaust system or meth injection). ...

      The whole world knows the BMW X7 is on the way and will be assembled in the United States. Engine choices will likely mirror the X5 and X6 but the X7 will be bigger and heavier. If one were to guess just how much this behemoth will weigh the ~5700 pound range of the Mercedes-Benz GL-Class which will be its main rival is likely a good ballpark. We have an idea of what it will weigh and what motors it will have, but what will it look like? ...
