There would mean the S4 was underrated by 15% and the 335i which has been clocked (if your believe dyno figures) at 350hp which is in itself an underrating of about 15%. |
from what i noticed of members post (correct me if im wrong), it seems that most are getting in the neighborhood of 270hp at the wheels...maybe a little more. with a drivetrain loss of 15%, which amounts to 40hp, thats only 310 crank hp. at 20%, its 324 crank hp.
