 rosten performance
  • Engine was built by me using all the parts i supply.
  • Note that this is with off the shelf standard K04 RS4 Turbo's
  • The Dynapack used in this test is known to be "strict",
    so the numbers might actually be a little lower than others.
  • But for sure,i don't think the RS4 Turbo's can be pushed more than this.
  • The car is VERY easy to drive on the street (which you can see from the torque curve)
  • The sheet shows wheel hp/Torque
  • Converted to Crank hp (most common in Europe):
    458 chp @ 6700 rpm
    637 nm @ 3400 rpm
