Problem with factory pulley rubbing on ATI P1SC housing

[IBChillin32182]

I just bought a 2001 Bullitt with an ATI P1SC on it. The factory ideler pulley that sits right below the supercharger pulley towards the passenger side is rubbing the back of the supercharger housing. It apparently has a little play in it and it moves in and out and touches the supercharger housing. There is probably only an eighth of an inch or less clearance for the pulley. Could I put a washer on each mounting point to push the supercharger back away from this pulley like another eighth of an inch or would it make the mounting points weak. If this will not work what should I do?

Well first of all you should take the charger bracket off and tighten the idler pulley back up to the block. I wouldn't accept a pulley that wobbles on my engine personally. If I'm not mistaken its just a bolt that has a idler bushing through the pulley. I'm not sure why the bracket would rub if your using the proper mounting hardware for the bracket. If you space the bracket back off the block from one of the mounting points then you might be taking the superchager pulley out of line with the alternator pulley. just a thought.

That also had me worried about getting the belt out of line. Hopefully the pulley is just loose and I can tighten it back up.
