[Rollins_2241]

I want to clear the beams before on the stop (.270) because data on delay and rollout is vital and don't want to make my bracket data useless.

With a 4150-style carb and an old box I can only come off in low gear. I try to kill it down to 4200, and am usually on for 1.5 to 2.2 seconds depending on the air. When it comes off I shift on RPM, to me using time is another variable to avoid unless you need it (high-power car). I usually run 131-134 all out and only lose 1 mph on the stop.
