You're trapping 112 which makes me think you're only running a 26 inch tire.
Ever tried a 28? I've got a similar setup revving setup and haven't brought it to the track yet with the 4.11's. I know I'm going to run out of gear on the 125 shot, but I'm just gonna let off at the 1000' mark anyway.
thehueypilot said:I'm getting ready to do the same thing going from 4.11 to 3.55 but because of traction problems. You will lose 60' time which will lower your ET. It also depends on how high/quick you have to rev your motor to find the best shift point.
