MOTM - Sep '18, Feb '16
I have two sizes and 21 gears. Depending on the power I am making I can adjust the RPM to any speed. As an example .The engine makes max power and the torque drops off around 11000 rpm with a stock engine. That is a 14 /42 and 26 hp that is around 100 mph. To much gear and you go down the track at 10000 because you don't have the power to go faster. And to little a gear and the engine is revving past the power band. Sounds nice but it is slower that before.
I run can everything from a stock 250 to a nitrous 300 and now I can gear for it with ease. I built it with the larger rear tire so I know the smaller tire will fit.
For acceleration like Drag racing I will use the smaller 130 tire.
