Thread: supercharger making noise

I noticed my supercharger makes a crazy noise when i starts it up. Its sound like a high pitch squeak. I thought it was the belt but i replaced it and the noise is still there... Can anyone help me?????

I get a similar noise coming from the s/c but more like a grinding noise should I be worried? But once it warms up it goes away

C) Bearing going out, not a fun replacement, seek search bar and how to replace bearings.

Yea I have a K&N CAI, so its normal then huh.
