I run a 279 45 17 new II version on my truck mid 1.6 sixty foot ( still tuning the new set up) Start the burn out in 2nd gear. As you shifting from 1-2 is extremely hard on the sprag. I run 2nd gear to 4750 and count to 4 drop the line lock and roll off the throttle. THEY HOOK. I leave 3750 on the brake and first gun is 100 dead off the brake. No issues at at 19PSI. But they prep the hell out of this track. I have seen more than one person had a shoe pulled off that was not tied well. Flip flops on people working / walking on the staging lanes is funny as well.
Any one that runs Star dragway in Denton knows what I am talking about.
