I think I'm a bit too small on the pulley.. It looks like the impeller speed is at 56925 with the 2.50 charger pulley & 6.875 crank pulley @ 6000rpm..

Thanks for the link.

Thanks.. They are a bit overkill... 13" up front & 12" in the rear... The down side is now I can't run a nice tall slick & front runner.
