What is the difference in a car that is supercharged and a supercharger?
One of your friends is wrong. Either the car is not supercharged, or it is supercharged and has a supercharger. If your friend’s GTP is 2003 or older, I hope he doesn’t park it in a garage. See the following: “In March of 2008, GM announced a plan to recall all 1997-2003 Grand Prix models with the supercharged 3.8 liter engine (GTP and GTX models) due to a problem which causes fires in the engine compartments of these vehicles. Over 230 fires were reported. This recall will affect over 200,000 vehicles. GM sent a letter to owners of these vehicles on March 13, 2008, instructing owners of these vehicles not to park in garages or carports until the problem is resolved”.
