I want to under drive my 1990 cavalier do you guys have a list of pullies I can use. If you guys don't know I'll try my hand at figuring it out. To underdrive a cars pullies I need to make the pullies smaller right?
You either need a smaller crank pulley, or larger accessory pullies. You end up "underdriving" the accessories by making them turn slower. As far as a direct fit, I will almost guarantee there isn't one out there, or it would be common knowledge by now.
