Great run!

According to the testing that Morris has done, the F2 at the blower speed I was running.......it soaks up 250 hp. So if I was getting a true 1100 through the flywheel, the bottom end and head gaskets where feeling 1350 or so.

I'm calculating the truck to be about 1100 flywheel hp. Having a 4l80e trans and a 14 bolt rear axle it's robbing a lot of power as well.

Going back to test this Friday. If we can put the power to the ground I'm hoping to run a little better than last time out.

Believe it or not the 80e doesn't rob hardly any more then a 60e. The mechanical advantage in lower gears is different due to the ratios but in a true 3rd 1-1 pull they are similar.
