This I don't get, maybe it's the engineer in me, but the damping ratio from one pulley material to another can't be that different, especially since they're both made from elastic materials. Stiffness, and mass, definitely...but "harmonic" damping...show me what you're talking about. Is there a dashpot built in to the pulleys that come stock with the car, or is there some extra damping treatments added to them to help with vibration? Or does no-one really understand vibrations and just spout out crap they heard from someone else?
