Bought a supercharger so I could swap out my supercharger for a rebuilt one (no issues with mine, just like peace of mind on long trips). So I am paying it forward if you need one and you don't want downtime like me, here is a clean, supercharger with very good coatings (I was pretty surprised how well it looked inside) and no pulley. Car had 80K when I swapped and it's been sitting in a box every since.
