I am somewhat new to a big block powered hard tail dragster. I am looking for tips on whether or not to use a two step to lower the launch rpm. If so, what should the rpm be set at, then how long before turning the throttle stop "on"?
seems to me if the launch rpm is low, then you release the trans brake button, the rpm will jump considerably before the first timer activates the throttle stop. Even if you have a small amount of time in the timer, i.e. .10sec, or...?

any help on how to correctly set this up would be helpful.
I have a 555 cu/in hard tail dragster with a #1 base plate "air activated" stop.
I don't exactly know what the converter stall is yet, I believe it is around 5800 rpm.
