we just recently put a jackson racing supercharger on a integra gsr, for the second time now, and are wondering how it's supposed to sound? from outside of the car...it sounds normal. from inside of the car while driving it, it makes a rough or grinding sound. is this normal? the sound is not loud, and it only makes the rough/grinding sound at idle or when starting to go. when you are accelerating, the sounds go away. we think that its just the sound of the supercharger turning, but we dont remember it making any of these sounds last time we had it on....someone help...thanks
