when to launch in a drag race

[wynode]

yeah i reckon 2nd or 3rd amber light is a good timin 2 launch off..if u want a good reaction!..by the time u put your handbrake down its probly 3rd or mayb green light
an il say around 4000-6000 rpm between their for a good launch

Dood serious. How do you know? Have you even been to a drag strip and driven a car down it?

I went on the first amber light and still got a pretty slow reaction time.
