I have a 1997 gtp I recently bought and it has some what of a ticking noise coming from what sounds like the supercharger.I pulled serpentine belt off and there it a little play in the pulley. Not front to back from supercharger but if you spin pulley left to right it has just a little play in it. It only makes the noise when at an idle. And its not a very loud noise but you can feel it in the SC also. When you give it gas and it build pressure there is no noise. SC oil level is fine. Car seems to run great and power seems fine. Just can't figure out what the noise can be or if i should be worried and what further more I can do. The guy said he rebuilt the supercharger. I have jot taken anything apart to see. But the shaft part of the SC with the pulley is new. You can tell that just by looks. Other than that I don't know what's been done or what I can do to actually find out.
