Cosmo Racing Underdrive pulley

[Flip-Side]

I don't know if anyone else has posted this, but I just stumbled across cosmo's Underdrive Pulley for the base vibe. I was just on the site checking out the short-ram I want, and there it was. $55 to boot. Unorthodox racing is a few hundred dollars, so is this too good to be true? http://www.cosmoracing.com/pro...d=813

After reading that and some other information on pulleys, there is no way I will install one on my car. I didn't realize that you would lose the harmonic balancer on the crank. It's there to prolong engine life, and I'm not gonna chance it for a couple HP. Thanks wicked.
