im going to buy some underdrive pulleys this weekend and wanted to know what the difference is between the race and non race, how will it affect my cars driving i dont see how it would effect emmisions which does niot matter "i know a guy who knows a guy who knows..." im not worried about emmisions. let me know im going to tommie vaughn tommarow. thanks

Dont put the alternator underdrive on if you have the factory alternator because you will have charging issues, other then that, pulleys are well worth the $
