    • Klasen Motors dyno testing their C7 RS6 Garrett G42-1200 4.0 TFSI V8 single turbo conversion - 1000+ horsepower

      AudiBoost posted a few articles on this single turbo kit it from Klasen Motors for the first gen Audi 4.0 TFSI V8 but unfortunately there is not too much in the form of data or results to go on. This new video below from Klasen offers the most data about this kit to date.


      Unfortunately, we do not speak German but dynographs are universal. It looks like they were trying several boost levels out until eventually hitting 887 horsepower before backing out of the run:


      Klasen previously claimed 1000+ horsepower but AudiBoost is not sure if that claim is wheel horsepower or crank horsepower. They never responded to inquiries regarding a high resolution graph to prove it one way or the other.

      As the video goes on Klasen seems to talk about a 50/50 methanol mix and boost settings.

      Boost hits 2.59 bar or 37.56 psi and they post 1008 horsepower to the clutch although the run is not made all the way through to the redline:


      Impressive? You bet. The questions are how much does this kit cost? What is done to the transmission? How is it fueled?

      We should start seeing more and more 1000+ wheel horsepower 4.0 TFSI's and the cars with the 4.0 TFSI V8 are becoming quite the bargain.
