You're looking at approximately 2K for the supercharger and the clutch assembly.

What is the failure mode of the supercharger clutch? On the 55K cars the electromagnetic clutch is also a common fault. On that engine it is the bearing in the clutch which generally fails. However it is possible to source a replacement bearing in the aftermarket and repair the clutch at minimal cost; no more than $100 for parts and machine shop services. Is a similar repair possible on the C230 supercharger clutch?
