V8's usually have a heavy pulley that acts as a harmonic balancer. The V6, being better balanced and not producing as much torsional stress as a V8 is less likely to see any long term problems. I've never heard of an underdrive pulley causing crank failure. I know a guy with a probe GT (V6) who's been autoxing with a crank pulley for 5 years with no problems. The crank pulley produces almost all of the HP. The other pulleys are pretty much for looks as UR admits they don't like to underdrive the accessories very much. The crank pully will produce 4-6 hp on our cars for 180 bucks. That's about 36bucks/hp. Not bad IMO since most mods are about 100bucks/hp. Just my .02.

Hey! UR is claiming 10 to 15 HP at the wheels! Also From other posts, I hear that the pulley produces a difference that you can really feel! So whats the deal? is this BS or not.

Hey EJ? How do you like YOUR pulleys?

I feel it.....more importantly, my g/f feels it.......she says it pulls much more in third gear.......i think it pulls more in all the gears.....i think i gained 10HP, but that's just a guess unless i can dyno it......i would have to say i got more HP from the U-R pulleys than the Injen intake, and that was giving me 8HP, according to the dyno.....i believe U-R's claims are accurate
