Will removing the supercharger belt on my 16 year old daughter's 99 GTP hurt the engine?

Removing the supercharger belt on your daughter's 1999 GTP will not directly harm the engine, but it will significantly reduce performance, as the supercharger is essential for boosting power. The engine will run in a naturally aspirated mode, which may lead to a decrease in efficiency and responsiveness. Additionally, ensure that any necessary adjustments or modifications are made to avoid potential issues with the engine's tuning or fuel delivery. Always consult a mechanic for the best advice tailored to your specific situation.
