Uprev, am I ready yet?

While I agree that upgrading the crank pulley is a controversial upgrade for this platform, I have no ill effects with mine after about 7k miles. The stock pulley on our vehicle is not a dampener and does not have a dampening system built into it, just a piece of rubber that tends to rot out quickly. I will say that because it is not as heavy or thick as the stock pulley, it is structurally weaker. This is my own opinion; I don't think that rotting piece of rubber is the line between a perfectly running vehicle and potential catastrophic failure. The crankshaft in the VQ37VHR is internally balanced to remove resonating frequencies. Many vehicles from a decade ago or more, relied on some form of external dampening system.
