I have a 2004 GTP with the 3.8L engine and supercharger. When I bought it a few years ago, it didn't have a belt on the supercharger. The more I look at hooking it back up, I'm thinking there might be major issues, so it would not be as simple as just installing a belt for the supercharger to work. When I start the car, the supercharger pulley rotates a couple times then stops. What's really concerning is a chunk of the old belt wedged behind one of the pulleys. So I'm betting there was a serious belt or pulley failure & the prior owner didn't want to deal with it. I'm no mechanic and this is my first experience with a supercharger. Any helpful suggestions are appreciated.
