My dads car is a 97 gtp, well his car has been running with no boost for a while now. The first time this happened the idler pulley locked up and shredded the belt, but fixed it and it was fine for a while. This time its not making any boost and cant figure out what it is. I checked the supercharger and the coupler is pretty shot so ill need to replace that. Just cant figure out why it isnt making any power. The boost bypass seems to be working when reving the motor you can see it open up and hear the supercharger whine a little. What else could it be. Would rather order the coupler with whatever other parts i will need. Thanks for any input guys
