Do I really need the alternator underdrive pulley? I have a large system and my voltage is allready pretty low. Will it sacrafice much power? Whats the deal with running stock alt pulley?
well in the instructions for the march u/d pullies, it said it might cause problems, and if it did all you had to do was add a lock washer because the alternator shaft is longer on some cars and i guess slips if it is- causing charging problems. i didn't use the lock washer though
