6.44 1/8th at 107.18 MPH

According to to my FAST XFI, here are specs off the motor for this pass at the top of 3rd gear.

Yes, 850. Based off of My Fuel lbs/hr I beleive it would calculate to 736 or so to the ground.

Your converter is hurting your potential. 6450rpm is way to high for that mph. You sure you had the throttle all the way open? TPS 86%? You should have a lot more left if you can get the converter slip down some.

.... You sure you had the throttle all the way open? TPS 86%?

.... he didn't get it to WOT.
