corning_d3 Posted December 9, 2005 Report Posted December 9, 2005 What kind of gains can i expect from a set of underdrive pulleys? Quote
corning_d3 Posted December 9, 2005 Author Report Posted December 9, 2005 any noticeable difference in slower pulley speeds, such as low alternator output, power steering effort? Quote
TeeJay3800 Posted December 9, 2005 Report Posted December 9, 2005 Not if you use a FFP pulley. Maybe a slight voltage problem if you have a huge aftermarket system, but I don't know for sure. Certianly no problems with stock equipment. Quote

dbtk2 Posted December 12, 2005 Report Posted December 12, 2005 No problems with the one on my STE or the one I had on my Lumina. Always had plenty of voltage. The gains were definately there as well. I got a 3 tenths gain in the 1/4 mile out of the Lumina by installing the UD pulley and removing my cat and mufflers. Shawn Quote
