I just bought a 2000 Mustang GT with a Saleen Series II Supercharger. The diameter of the pulley it has now is 2.8 inch diameter measured from the pulley ribs. Does anyone if this is the stock diameter? How much boost is it producing with my current 2.8 pulley? Any input is greatly appreciated.

 

I have the same supercharger on my 04 mustang gt. I have a 2.5 pulley on my. I'm not to sure on the stock pulley. But I do have a question about your mustang if you don't mine me asking
