22 lb wheels?!? Good lord! Go ahead and do the math following the steps on church's website on what you'd have run w/ stockers...at 8 lbs a wheel difference of stock vs your wheels, that's 16 lbs of rotating mass...I bet on stock wheels you'd be 235.

wow, i wonder if i'd of hit 230 without my 22lbs per wheel ASA AR1's? i know their heavy, but their still within one pound of LMs. i bet i might have hit 13.4 with some stockers on too. hmmmmm.....

I thought I've already ended the debate as to how high his dynapack actually reads? I've posted many times that it reads 9% higher than AutoWave's dyno dynamics dynomameter, which reads 1-2% lower than a typical dynojet. Therefore, his dynapack reads 7-8% higher than a typical dynojet. I wouldn't call that significant.

You guys need to look at more than just the weight of the wheel. What really matters is the weight of the wheel/tire combo. If you have a 15 lb wheel and a 20 lb tire, the combo is 35 lb. If you have a 20 lb wheel and a 15 lb tire, the combo still remains 35 lb. Also, you don't want the weight to be very far away from the center of the wheel because that reduces some physics crap. Should have paid more attention in class, dang it
