I think that TurboXS got 222 whp from the EVO and 264 whp from the Sti. So that would be a 18% loss for the EVO and a 12% loss for the Sti, so it looks like the Sti is very similar and even a little better in the drivetrain area. As far as the WRX, yeah its drivetrain isnt near a good as the Sti or EVO, but then again the WRX cant compare to the EVO, thats what the Sti is for.Originally posted by AlexWRX
It is a widely-accepted fact that WRXs and STIs have higher drivetrain losses compared to the Evos (and the Skylines, obviously).
