cadowns Posted November 14, 2007 Report Share Posted November 14, 2007 I think it would be best if you would read and write more about what you are thinking so that we can all be able to help you better. There is not a lot to be gained with a N/A underdrive pulley set. CD Quote Link to comment Share on other sites More sharing options...
Z06 DREAMING Posted November 14, 2007 Report Share Posted November 14, 2007 Typically underdrive pulleys will add 10hp, and improve your ETs by 1/10th. You can buy them in a set of crank + alternator or just the crank pulley(one with most gain). TBYRNE(a sponsor) has the ASP for our trucks or you can search elsewhere for similar pullies like powerbond, etc. Quote Link to comment Share on other sites More sharing options...
