As the title says, I'm trying to decide which crank pulley to go with. My S4 just hit 100K miles and I think it's still the original crank pulley. Got the car pre-owned and the service history does not mention anything regarding the crank pulley. Been on Stage 2 for about 15K miles and I drive occasionally drive aggressive. I figured it might be a good idea just to have the crank pulley changed out due to mileage and since I may be taking a 2K mile road trip in a weekend soon. I was set on buying a Fluidampr until I just found out that the pulley weighs almost twice the weight of the stock pulley. The JHM OD pulley is lighter than stock but my main concern is how it affects the engine since it's a V6 and the pulley doesn't have dampening. Need some help deciding and wondering how many miles have people ran the JHM pulley for.
