you're gonna have to give some info on the motor. But there are so many variables in this equation, that anything here is gonna be purely a guess. I recently went from a budget 11" ACC 3500 converter, to a custom made Lupo Dynamic 9-1/2", and enitial passes would suggest I picked up over a tenth in 60', and a few tenths in E.T.

Only way to find out is gonna be to make passes.
