Up for sale is the supercharger from my 2007 Cobalt SS Supercharged. It has a 3" pulley on it which has been on there since 40,000 miles or so. The silencer ports have been professionally plugged when the supercharger was rebuilt around 40k (when I changed pulleys). The whole thing was taken apart, cleaned, new bearings installed along with fresh oil. I didn't replace the rotors because I couldn't find anywhere that sold them, so there are a few scuffs on those from when the blower bearings went bad at 40k. It doesn't affect performance and makes 13psi of boost on a 90 degree day with the a/c on.

The blower is in good mechanical shape with no shaft play. It is quiet at idle.

I'm not sure what the going price would be for this, but I know they are $800 new from ZZP. I think $350 OBO is a decent asking price considering the recent rebuild. Here's a picture of it on the car... as you see I like to take care of things and keep them clean:





Thanks for looking!

 

I may be interested depending on how the silencer holes were plugged, do you have any pics?

 

Quicksteel. When it was apart the shop honed the inside where the rotors are so there isn't a chance of it coming apart. It is kind of cool to hear the blower without having to floor it

 

Bump. Somebody help this car find a bigger blower!
