Really the pulley thing needs its own thread, or one of the existing ones, or it will take over this thread in the end heh. It's been debated endlessly in the past. GTM is showing clear evidence of the problem with removing the aluminum pulleys, and that does kinda suck.
I'm more interested in the whole "NVH" vs "real balancer" side of the debate. If the rubber ring on our crank pulley is truly balancing the engine rather than just reducing NVH for aesthetic purposes, then a few vendors have a lot of potential engine damage to answer for...
