I was cleaning out my supercharger intake, and upon removing the rotors I noticed that the surface of the rotors are chipped right along the (apex?)seals and in on the rotors themselves. The coating is gone on approx. 75% of the one rotor, and about 25% gone on the other rotor. I believe at some point in time, something had to of gone through the rotors.
The supercharger still made good power even before I found this out, but I want to replace the rotors with new ones just for peace of mind. Can I find just rotors somewhere, or do I have to buy an M90, tear it apart and hope the rotors are mint?
