pulley without dampener

Think about it this way when comparing your daily driven car to and F1 any other race car, they rebuild their motors every race or every drag race the motor is torn down.

How often do you plan on tearing the motor apart and putting it back together? If you plan on running your engine for 1-5years without pulling it appart again run a dampner like the oem one or aftermarket like ATI or Fluidampr.
