I would say use some fine sandpaper to sand out the scratches and then some mothers aluminum polish to shine it back up and remove the sanding marks.

Re: Scratched supercharger
Depends on how deep the scratches are. You can definitely get them out, but it might take some work. Do a search for "polishing the plenum" on this site and you'll get a world of info.
