Drive train loss on C4s
What is the usual drive train loss from flywheel to rear wheel horsepower on C4s, I have a 90 and was wondering what I should calculate to get a general idea on my rwhp. :cheers:

I figured up about 17-18% for my A4, and the ZF should lose about 15%

:iagree: But I always wondered how you could be sure that the automatic is only giving up 17-18%. I'm told that temp/humidity extremes can adversely affect your engine performance but does anyone know if they can also affect the drivetrain loss as well?
