that would depend on the type of car / mod ur driving.....

every hard to give u a exact graph...
but in EP terms,u have to match the pitch of the gears...eg a 0.64 pitch spur with a similar pitch pinion.
pitch means the no. of teeth in an inch...so it will sort of determines the size of the teeth...

usually GP use 32 pitch. bigger than usual EP 48 pitch. but now, i noticed especially the G4 Team magic GP car use even smaller pitch...don't know what pitch but not the 32P. even MTX3 use smaller pitch

to calculate the final gear ratio...u have to know the internal gear ratio....thats simply divide yer rear big pulley with rear gear diff(ball diff)...and then u times the ratio of the spur/pinion from the engine.

sorry, i don't know how 2 explain this in simple english...im not good in ENG anyway... pls help...initialD
