OK guys, if you have a motor that dynoed at 180 HP on a Motor Dyno, and you were calibrating the clutch using a chasis / track dyno, what would be the optimum % of Horse Power to the track

I have heard alot of different #'s and I am trying to figure this out!

I think the best you can get is about 55%, and maybe 60% if your clutching and track are set up perfectly.

be sitting down when you run it. 55% is going to be real good.
