Starting line rpm enhancer for foot brake.

I race at 2 tracks in my local area, the nhra track calls the footbrake class NO BOX, allowing 2 steps & transbrakes & line locks, the IHRA track calls it non electronics, no 2 step or transbrakes allowed, im old school, true footbrake, we are racing for enjoyment, u will not win enough money to support your habit:D
all the tracks in my area allow that (0-13.99) when i used it i would pre stage flip my switch bump the throttle, it was set at 1200 then start to bump in with my foot resting on the throttle, what do you think this guy is doing [ame="https://www.youtube.com/watch?v=WeWOtiYrAas"]American Bracket Racer Episode 1 - YouTube[/ame]
