Ive been trying to watch those vids since you posted them.Finally i got them to load. Watching that truck launch,the torque that engine makes is insane,it literally leaps out of the hole defying its 7300 lbs. When hes powerbrakeing lighting the turbos,I am guessing from the sound of the engine,that hes at 25-30PSI when he launches . There arent many trannys that can hold that HPfor even one second. Those BTS Ford trannys are tough,the modded Cummins can turn almost any trans into shrapnel in a few seconds in 4wd building boost with your foot on the brakes.That one is holding up great!
