The 1255 lb of torque pull was with a 5" pulley on the blower, the 1188 pull, I used a 5.5".both used the 7.65 crank pulley. I wanted to do one pull with race gas and more timing, run it up to 7000 rpm but I ran out of time.

Interesting, seems that at about 5000rpm the belt starts slipping. Which has more area under the curve? Because of the slippage problem, I would use a bigger pully and less boost and extend your rpm range. I would bet that you would be able to go faster with a bigger pully and no slippage.
