I figured this might interest someone here. I'm selling a supercharger I pulled from the junkyard about 10 years ago and never did anything with. It's an Eaton M62 from an early 90s Bonneville SSEi. It's got a bunch of oil buildup on the surfaces, probably the car was burning some oil or PCV was messed up. The rotors of the supercharger are clean-ish but everything else internal is messy. The rotors move smoothly and don't seem to have any lash between them. But I'm selling it as "probably needs oil changed and maybe snout bearings." Similar ones on eBay are listed in the $400 range, I'm asking $100 here, plus shipping. Located in Columbus, OH and local pickup would be just fine.
