Belt problem
I have had underdrive pullies for quite awhile and no issues. Recently bought a vortech supercharger kit so I had to change the water pump and crank pulley back to stock. Got a new belt and tensioner. Have no issue cruising but when at wot There is a very bad vibration. So I figured the belt was too tight since it was a bit of a pain to get on. Bought a 1/2 inch bigger belt and the vibration is gone. But now with a quick rev or wot the belt squels because it is not tight enough. I don't know what to do now. Any thoughts?

So I spaced out the alternator a little bit.., but I'm almost positive that the noise is coming from the alternator pulley., is there a way to test if the bearing is bad? I don't have any charging issues

I'd love to know how much that supercharger cost?
