I run 13.47- 13.57. My 60-foot times are 2.0X seconds, and ET is fairly consistent. My weak point (as above) is reaction time: I’m all over the page. I spoke with the driver above before the race. He has been racing since 1966: 40 years of experience shows. The driver is so sharp that he hits the brakes at about the 1,000 foot mark. I passed him at 104 mph like he was standing still. LOL. Still not good enough.

Sometime ago, the green light was set to 0.50 seconds. So a perfect reaction time was 0.50 seconds. Any reaction time better than 0.50 seconds is a red light: you are eliminated. Today most NHRA tracks are set to 0.0 seconds, so perfect is 0.0 seconds. A negative reaction time is a red light: you are eliminated.

.400 has been for a pro tree and .500 has been for a sportsman tree, traditionally. Recently many tracks have been switching to a .000 tree with .000 being a perfect light, anything -.001 and under is a redlight, anything .000 and above is not. The timing of the lights is still .400 seconds of yellow for the pro tree, and .500 between yellows for the sportsman.

.400 is pro tree red all yellows green
the new leds are .000
some poeple run instant green to similate street racin
I was just curious david. It sounds like you're shallow staging to get good et/traps at the expense of R/T. In bracket racing you should instead sacrifice good times and go for a better and more consistant R/T by deep staging, and adjust your dial accordingly.
