    Cobalt SS Questions

    Ok, Im considering buying a Cobalt SS. I have some questions.

    1) Is Limited-Slip standard on the SS model?
    2) The first mod I'd do after the break-in period would be a supercharger pulley. The stock pulley size is 3.5", I've read that a 3.25" pulley will give 2psi of extra boost. How much additional HP would this yeild.

    1) No it's 1500 bux
    2) Stock size is 3.5 inches. The GM performance book for the ecotec lists it as 84 mm or 3.3 inches but it doesn't seem to be. I don't know anyone who has done a pulley mod yet so I can't help you on power.

    There is a company that makes pulley so you can try it if you so dare. They also say the stock pulley is 3.5 inches. Maybe there is differing measurement systems
