    • The world's most powerful B7 RS4 - 1014 awhp twin turbo B7 RS4 4.2 FSI by M2 Motor Technik

      Many of you have probably wondered why the Audi 4.2 FSI engine never made big power with forced induction compared to the R8/Gallardo V10 which is based on the same basic architecture (same bore and stroke).


      M2 Motor Technik decided to show what the Audi V8 can do when properly turbocharged and the result is spectacular.

      1014 all wheel horsepower on a Mustang dyno:


      This is the only 1000+ wheel horsepower B7 RS4 AudiBoost knows of and the first to top 1000 awhp. The output obviously puts supercharged setups to shame.

      Just for perspective, a stock B7 RS4 puts down roughly 314 awhp on this dyno. We are talking literally more than three times the power over stock.

      In theory this also means Audi R8 V8 models can make some serious power despite nobody getting there just yet.

      Yes, none of this comes cheap and you need a built motor to begin:


      Then add in the turbo kit and tuning and we are talking about $50k or so although pricing was removed from their website for whatever reason.

      It is worth every penny though. Nobody else is anywhere near this output on the platform.

      More details to come.

        V.S Motor and TE Motorsport built a 1225hp bns rs4 engine in 2015/2016.
        The engine was used in a RS4 B7 ex DTM pace car, and I belive it was built for the Gatebil extreme series.

        I tried to post videos, pictures and an old for sales ad, but I did not have the rep power to post them.

        I have not found a lot of movies of it actually driving, but at 25 seconds in this clip you can catch a glimpse of it (its a blink and miss moment (video car I belive is a 700hp e30)).

        Her is the old ad: https://racecarsdirect.com/Advert/De...illclimb1200hp

        It runs Precision 5562 turbos and 1200cc injectors.

        V.S motor (Vidar Strand) you might remember from the mid 2000s, he built that e34 m5 with a 1000hp+ that was all over the internet.

        I did not try to discredit your car, I was responding to this claim:

        1225hp was achieved on ignite e98 with 1.7 bar boost, whether or not this was with 1200cc injectors I dont know, its currently for sale again in Norway, and thats where I got the information about the turbos and injectors. The car is currently running 930hp on 1 bar boost, I don't know if they also installed smaller injectors.
