Re: slp underdrive pulley power gain??
Try a search. There's been a number of threads about UD pulleys.
But you'll see about a .15 off your track time. -GMHTP
I've heard claims of 10-25hp. Get the ALT pulley w/ it. It will correct the RPM differance. (AWSP pulleys) I do like the raised sidewall claims, tho.. But I've only heard of a few throwing belts.
