Hey guys, this is only my 2nd post on this site, so lets get to it. So i just recently bought my 2000 grand prix GTP and i've grown up on nothing but ol' muscle cars and antiques, so this computer jazz is super new to me. I understand that when i bought my grand prix that it came with a 2nd supercharger one that had a 3.0 pulley that is.. "Keyed"? I would like to change the superchargers out but im not sure how to go about doing that, and the 2nd supercharger looks exactly the same as the one installed, only difference is that the pulley is much smaller .. thanks guys, and sorry for being new to this lol
