I've never had any experience with underdrive pullys but i figured since my belts are sqeaking and it sounds like my bearings in my idler are shot, i might as well upgrade. I just wanted to know if you guys had any advice or input.

As I understand it, about 3 to 5 hp. But it's across the rpm range, not just peak. www.uucmotorwerks.com has a dyno chart and info on pulleys, as do others, I'm sure.

yeah, I know more than a couple of you have some sweet fixed up bimmers. Please answer us this. I am going to get pulleys, but I still want to know what I am going to (ornot going to feel). I heard from like 1-3 horses. Also, how easy is it to install?????????????????
