Horsepower Freaks Stage 5 turbocharged E46 M3 cracks 1000 horsepower to the wheels
Congratulations to Horsepower Freaks for continuing to raise the bar on the S54 platforms. Dyno numbers over 1000 horsepower are simply no joke and that level of power is difficult for many to even comprehend. The highest figure was hit at 29 psi as going above this amount of boost produced diminishing returns. They intend to dyno the car again with smaller wheels which should make an appreciable difference. It is likely at this point head flow limitations are starting to be hit and Chris at HPF hinted at the cam profile possibly being a liability. Regardless, we are seeing some amazing things out of the S54 that nobody would have ever thought were possible not too long ago.
