Hey Adam. I can't tell from the acceleration chart how long it actually takes to get to 40 as the scale of the x axis looks to be in minutes, but i'd trust that whatever clutch set up you use would work better than what i'm doing. i would like to make the most use of the 2 shoes i have and maybe jam it up some day with 3. seems like those 2 shoes on the other thread might be the thing to try.
