I've been trying to get to the bottom of this noise coming from my supercharger. It knocks like a plastic screwdriver handle in a blender on low. I'm very proud of the sound my exhaust makes. The motor sounds like a V8 and has lots of lope, but now I'm embarrased to drive it anywhere because of this knocking noise in the supercharger. It is very noticable inside and out of the car.
I took the sc belt off and it goes away. When I turn the pully back and forth there is a little play in it. The play is about 3/16 of an inch and when I do it fast I can hear that that's where the rattle/knock is coming from. What do I need to do to make it go away? It was just magnaported and rebuilt about 1000 miles ago. It knocked before the rebuild also.
