The supercharger has been a little rattely since I installed it, but I think it was normal. Then this last week it got extra quite, you almost couldn't even hear the supercharger except for the whine when boosting. I drove to work last night and it was good, and then when I left work this morning it suddenly sounded terrible. Very loud rattle coming from the unit. It "pulses" the rattle at idle and cruising. Then as soon as you go about 30% throttle, or when it tries to go positive, it goes to a constant harsh rattle. The whine doesnt show up nearly as much as it normally does when you try to boost. Just the very loud rattle.
