I looked it up and the avg human reaction time is .25 visually.
I've tested to an average of .16, maybe that's why I can go red on a .400 tree with my Turbo Action tranz brake valve bodied 904. A lot of people told me it wouldn't do it.
I've carried 70 in the delay on a .400 tree....I'm slow as molasses but the car makes up for it lol
5.53 @ 125 1/8th on the launch control..more left in her!
