Supercharger Noise

**Jbruce** · 01-10-2012

I noticed my supercharger making a noise while at idle and driving. Im not sure what it could be but I think i might have spun a baring, If I bought a new supercharger would that fix my problem?

Can you describe this noise? Sound like marbles knocking around in the snout? or like the rotors are hitting each other? or are you even sure its from the supercharger?

"I think i might have spun a baring" makes me think of my engine when I spun a main bearing and it started knocking and clattering like a diesel...is this more of your problem or are you sure its the SC?

A video (cell phone or camcorder) would be helpful

Supercharger noise is not a spun bearing. I'd say your supercharger snout bearings might be shot. Maybe the coupler. They're a lot cheaper than a new supercharger.

The noise is coming from where the sp meets the motor itself and I believe its the charger because when I got the car it had vary little fluid in the supercharger and after I changed it the noise when down a little but now its back and it sounds like a constant rattle noise like a broken barring would make. Now that I listened closely it might be coming from the top of the motor...
