Wow...now that's ugly!

Pull your plugs and look to see if there are any melted aluminum globules attached to the spark plug electrodes. Sometimes when you melt a piston this happens, maybe the same if you ingest little bits from your supercharger housing.

Buy the looks of the smearing, your supercharger housing must be made from simple cast 356 aluminum alloy. I would have hoped that the manufacturer would have at least hard anodized that sucker. But better yet, have gone with a higher silicon based alloy.

Kinda a moot point now I suppose!
