Lightweight pulleys work like this.. Depending on other mods, you may gain from like 8-12 crank hp, and maybe 5 WHP. Underdriving is for those with power O.C.D. like myself. You only net like an additional 12%, so instead of getting 5 WHP, I might have gotten 6 or 6.5. The only thing that is annoying is lights dimming at night. It was ok for the first 3 months, now it just gets old.
