I just need the weights for a school assignment. They dont have to be perscise but just an approx. weight so i can compare the advantage of the lightweight pulley versus stock.

kthxbye.

Most of the advantage comes from the fact that they are underdriven. Check UUC's website, should have the info on both underdrive ratio and weight reduction.

I find the pullies to be particularly not worth it. I'd get a crank pulley over underdrive pullies. I believe the most unorthodox racing preserve the harmonic balancer, so it will not do any damage to your motor.
