There has been a lot of *theoretical* discussion over the detrimental effects of "power pulleys". However, the only proven effect that I've seen is that it improves HP and torque (especially midrange as shown by several dyno sheets posted to the board) and more subjectively response. I have not heard of a single crankshaft failure, nor have I seen any actual scientific tests by independent parties. Just some *theoretical*, albeit well reasoned, discussion by parties who stand to lose revenue if the pulleys succeeded. I mean, why by a chip, when for the same price you get HP you can really feel?

Maybe not enough time has passed to see failures, but the pulleys have been around for a couple of years and my guess is that users of underdrive pulleys tend to be harder on their engines. I would expect that someone would have had a failure by now if they were so bad. Cheuk's car has a pulley and it's turbocharged.

Just my $.02 FWIW.
