I just finished building a new car, WRP$10 frame, small tires( 1 1/8" rear tires .435 wide),Proslot dragmaster 725 motor(110,000 rpm) 11 tooth pinion, 56 tooth crown gear, and hard body w wheelie bars. Fastest runs are 1.060 1/4 mile.others using this motor are in .850 range. Ideas on gearing changes?

Re: gearing

how much does your car weigh as compared to the cars running .850's?
what gears are your friends running?
is your motor broke in properly?

Re: gearing

I talked to proslot and they said this is the wrong motor for hard body cars. Made for 80gram lexan body funny cars. No bottom end all high rpm.
