zoom zoom, wizz wizz go the gears
Im really loosing sleep at night trying to figure out how to gear my B4, i have heard anywhere from advanced algebra calculations, to just run stock gearing? However what confuses me is, why use a 81 82 84 spur gear, when you could run lets say an 81 with a 20 tooth pinion, or an 84 spur with a 23tooth pinion. I have a FTB4 and a 12x2 mod checkpoint motor. Here and there i will put a money 19turn in, and run an 84 spur and a 24 or 25tooth pinion? But how do we know what our maximum gearing or minimium gearing should be? Can i run an 84tooth spur gear and a 23 or 24tooth pinion without overheating? or over gearing? Of im im looking for more punch off the line run an 84 with a 22, or even change to an 81 and run a 22! Just seems so confusing.
thanks for any advice,
