Thanks- I'm such an idiot when it comes to mechanical stuff. I'm hoping to learn a little from hanging around here a while.

That'* great. The impellers are fine if you're putting out that much boost. Any problems will be in the nosedrive. Either gears, bearings, or coupler. Hope for the coupler. It'* the easiest and cheapest. Or you can swap out the nosedrive. The important thing to remember is that the bulk of the blower does NOT need to be replaced if you're pushing 10psi of boost. Just the noise that needs to be fixed.
