it wouldnt be spark knock if you let off of it and it still makes the sound-if its an eaton you maybe getting case rub-call steggy
Detonation! Stop going WOT! Yo'll blow the motor.
You might of sucked a rock or screw in the supercharger?
Are you getting into boost at all? If so might be a bad tank of gas and causing detonation.
Yeah stop driving on the shiet, other wise you could cause some serious problems.
What he said!
If it is only doing it when you let off then I doubt that it is pre-detonation. Under decel you just don't have the load in the cylinders to cause it imo. I would look towards the blower. I am not saying that pre-detonation is not 100% the problem, but it just sounds out of character to me.
Are you sure it isn't your cats? When they go bad, it sounds like marbles in a can.
I agree. I had that before
As I rev the engine like to 3500rpm it makes the noise. when the car is on sitting there you don't hear it. The sound comes from the front of the supercharger like a bearing or something not sure from the pulley. Its an eaton all stock.

like i said earlier -eaton case rub-call steggy before its to late
Ya know,almost sounds like a idler/idler bearing that`s bad or going bad.That kinda explains the noise when there`s a load on them.
Who is steggy?
What about just buying a whole new supercharger or rebuilding it?
