Taking apart the super charger today

I think we found a problem we took the snout off the front  of the supercharger, sent it out to a performance shop in Florida. I used my Milwaukee  impact gun to spinet at a high revolution. I don’t hear nothing bad in the supercharger, but I definitely hear rattling in the snout.. I sent it out 2 day airmail.  The guy said anywhere from 2 to 4 days before they send it back out. Hopefully this time next week I’ll be up and running.
