When to shoot?

[madmanadam]

At what point do most hit the switch. I have been doing it in 2nd @ wot and my best for a 100 shot this weekend was 12.55 @ 114.2 with a 1.9 60', RT .062. To me I seem to be going slow compared to others.
Any advise?
Thanks

After you take off the line waite 2sec hit it see if that works.if you start to spin
Take you air pressure down to 23psi.You say you going a bit slow to who others with NOS or not.Yes I did say NOS.

Launch then hit it. The time you take to do the two things in sequence is sufficient delay.

PSI on street tires should be 20-22.

I have my tires @ 19.5 PSI. using NITTO D/R's

put a window switch on it and then you dont have to worry about hitting any buttons.the nitrous system will go on and off automaticly when its in the right rpm range
