Will a overdrive crank pulley damage the alternator?
My tuner is telling me that if I dont run a underdrive alternator pulley with my 10 percent od pulley my alternator is going to fly apart?
That was my thought as well I wanted to have my car back for a car cruise next weekend but the pulley is back ordered and it doesn't look like it's going to be doneIf your tuner is saying that I would honestly take your car elsewhere for any tuning. There is nothing wrong with running a 10-15% overdrive crank pulley with your alternator. Yes it will speed up the drive to accessories but no harm.
Yes it's a I.W. and they are going to make the alt pulley also. He also said that the GT alternator pulley is a different offset than the cobra one and that's why he's having trouble getting one.man thats rough, sounds like you have some pretty bad luck. Who's balancer are you going with? Innovators West?
