When do you activate your Throttle Stop?

[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.

Some great feedback guys. Thanks and keep it coming!

We are planning to test one or two different approaches tomorow at G-villle.

I think that we have been stoping and shifting too early based on the feedack here. Also, I like the approach of letting the car work on the line and then getting on the stop once it settles. This may be .5 out for me, but we shall see...
