Cool! I'll tighten that up and hopefully it fixes the problem. Also I have been searching everywhere for that other little part but I can't find anything. Do you know it's official name or part number?
Pull the supercharger and look, I had screeching noise and trouble shot everything. Pumps etc. finally pulled sc and bearing had blew up. Was like a shotgun blast to engine. I was too late and Had to replace engine. If you don't want to pull Sc Off can take hoses off and rub finger inside and look to see if anything is on finger, mine was almost like graphite powder. Hope that it's not and it's something else for you, was not cheap.
