What's the deal with pulleys??

NO NO NO NO

Bigger is not better. Here's how it works. If you put on a bigger crank pully lighter or heavier what it does is turn all of your accesories faster. this does not help you at all. In fact what it will do is burn out your alternator. Alternator's are design to performe optimally at anywhere from 2k->4k above this they produce too much power and CAN (not always) FRY your electical system. It also lighter or heavier will take AWAY HP's. A smaller crank pully will have less drag on the crankshaft and it will UNDERDRIVE your accesories (hence the name underdrive pullys). So it provides power in two ways.
1. It weighs less and has a SMALLER diameter there by taking less power per turn.
2. Transfers LESS power to the accesories freeing up this hp for the flywheel and in-turn (hahaha) the wheels. (this is also a benifit in high reving engines because over-revving accesories leads to where out. so the underdriving charactoristics of the Pullys actually preserves your accesories.)
