Hi,
I have a 2001 GTP, and just recently there has been a whining sound coming from the belt drive area of the motor. I have also noticed a grease type substance that is on the firewall and coolant resivour. Also the sound speeds up when you rev the car up. I have no experience with super chargers. I think it could be just a pulley from my experiences with naturally aspirated engines, but i am not sure. any help would be appreciated.
