Steve Dinan says: (As in Dinan BMW)
The Danger of Power Pulleys This guy is no idiot. What he says has truth to it, but it doesn't have to be taken as law. (Don't bother arguing the fact that he is talking about E36 BMW's instead of Contours. It all has the same effects in the long run) If I were you, I'd play it on the safe side. I personally am going to go the DMD route. If you cheat your way to quickly gain HP, the results will be brief before you have long term negative effects. I am in it for the long run myself. Don't forget about what else is hooked to the Crank pulley. (Waterpump, alternator, etc) Check and make sure turning them at different RPM is going to be safe.
