Your experience foot brake vs. 2 step regarding ET

[Rusty Davenport]

Would anyone care to share your experience with ET gain.....not drivability......which one is faster, slower, how much difference or any other comments. This would pertain to a stock eliminator type car.

.02 with two step

.05 quicker with a 2 step on my T-Bird.
But then it's not a V-8 nor naturally aspirated.

Larry and Alan,
When you use the 2 step is it set for the same RPM that you were footbraking to?

[Sam Capizzi Jr]

I use a 2 step with a button in Pro and footBrake in street when bracket racing and found that the 2 step is about 2 hundredths slower in ET but .02 faster in reaction time. This is at 3000 rpm in my car. I load the converter to 3400 to make up the difference in RT

Bob: In my case no, so there really is not a fair comparison I suppose.

It would be an interesting test tho to set the 2 step down lower to the point where I leave on footbraking.

Exactly my question------ like at 2000 on the 2 step OR if its a direct linkage quadrajet get on the 2 step before the secondaries are open----------anyone care to comment ???

All the Stock racers I have asked leave with the throttle already matted when using the two-step...I have not tried it yet. Mine is chipped at 3000 and I often hear it when staged. I have resisted trying it because it is just the opposite from what I am used to...leaving off the brake pedal instead of pushing the gas pedal.

So let me get this straight------you are using the 2 step but no more throttle than it takes to reach the chip ????

Not by intent, but rather by design Rusty. As you can see in the image the activation button is in the brake pedal itself...I know some use a micro-switch.
