Did you replace the front bearings with the rotors? That noise sounds like a bad bearing like a bad idler or tensioner but if your hearing it from the supercharger I would worry about the bearings in the snout.

The rotors you replaced would only be damaged if a foreign object went through them or worn bearings let them contact each other or the case.
