2 step question

[Coleydog]

I’d still like to know the advantage of using the 2 step in stock? I used it with and without a trans brake with a delay box in bracket racing

[MR DERBY CITY]

There is absolutely no advantage in using a two step in stock eliminator. If there was the whiny azz chicken chits would have it outlawed and rulebooked out of existence. YOU whiny azz chicken chits KNOW who you are. They operate by the principal of ….If I don’t use it ,it shouldn’t be LEGAL ….

Consistency in starting line RPM. I can also use it to adjust my reaction times. If I’m really amped up and can’t get out to let air out of the front tires. I can click the 2 step RPM down one or two clicks and it’ll slow my reaction times down. It’s also easier and more consistent (for me). To hold the accelerator to the floor. And just let go of the brake pedal. Vs swapping feet. I’ve been told it’s easier on the convertor but harder on valve train. So take your pick there I guess.



Older racer. Thank you. I thought there was a rule against having it adjustable from the drivers seat. But couldn’t find it. Thought the rule might have gotten changed when I couldn’t find it in the rule book.

My Dad wants to make changes like this after 'missing' a RT. I do everything I can do to not make changes to the car for RT as I don't feel I as a human I am consistent enough to say that dropping a few PSI out of the tires or changing launch rpm is the solution. Practice and routine is always preached by the hitters that win a lot of racers. Box or No Box racers. To me changing mechanical components along with human variability just adds another variable to the equation. If it does 'work' on a few runs to get a better RT, can I then actually say it was the mechanical change or me just doing a better job? I don't feel I can make that call. Could just be my misguided theory too, as I have won nothing...

Sometimes the psychological impact of a change can be just as (or more) important as the actual mechanical change.

Consistent leaves at start line without having to look at tach, thus taking away concentration at a very important time. Some cars are quicker ET wise with a two-step than off the brake. Make reaction time a little more adjustable. Those are some reasons. There are many more.

On stockers:

What rpm do you guys typically set your starting line rpm on your 2 step?

[Dave Gantz]

With a carb anyway, the car may leave differently with the throttle wide open, and rpm controlled by the two-step versus leaving with the throttle open just enough to hold a given rpm, or even from an idle.
Tuning may affect these possibilities, I've never tested the two methods.

With my 64 I would hold the rpm at 2100, = .01 2000. = .02-3, 2300 real close to big red. With two step and trans brake @ 3500 with pedal on floor delay box determined rt. I also tried the air cylinder on throttle lever with pedal on floor, idle it at 2000 just up to edge of converter (069 J) with four wheel line lock. I liked this system because of no stuttering. Let the button go and the cylinder pulls throttle to wide open (took awhile to get that set) with delay in the box. Popped button on top bulb. With those two systems it was .00s all night and still got sent to trailer quite often. One guy could bump the button down if he felt he was late off the top bulb, track champion quite a few times, dumb as a rock, could barely change his oil, his dad set it all up he just drove the car.

Are 3 steps legal in stock ? I don't have a rulebook in front of me. I currently have a 2 that controls burnout and a high RPM but would love to add a third for lauch
