Re: Super charger whine in neutral when revving
Talking out my ass but: Is it possible you filled it up wrong and there's just air stuck where the pump is that it can't purge? If you're hearing a whine after changing the pump, it's just too easy to assume the problem is there.
Many out here know the procedure to properly flush cooling. I don't.
