Hi everyone, as you can probably tell I'm new to the forum but I am in need of some advice.. I've just bought a TB evo IV to race on carpet but I cannot get the gear ratio that I need to run a stock motor. With a 96 spur and a 20 pinion I've got 7.32 on my TRF414 on the same track I wasrunning around 9.
Basically I'm cooking motors and seriously lacking acceleration
, can anyone give me any suggestions please
