60' and ET footbrake vs 2 step

ALMACK · 10-19-2024, 01:02 PM

.05 sec. for my 4 cyl. stocker

2 step vs. footbrake

but then again it's a turbo car so maybe that data does not apply to a n/a setup

To borrow from former NBA great Dr. J. (Julius Erving), "I'M OLD-SCHOOL", so footbrake racing is the way I go.
Besides, that's one less part in my car that can go bad when it's supposed to be good!

Are you guys using an adjustable brake pressure switch? Are you adjusting RT with brake pressure? Launch RPM? Or both?

I have an adjustable brake pressure switch. It has separate adjustments for ?arming? the 2 step and ?releasing?. This can effect reaction time a little, but mostly I use RPM adjustments for R.T.

I’m new to 2steps (previously raced transbrake cars) not knowing where to start I’m at 2800 rpm using an electrical switch on the pedal. I see cars that roll forward before lifting the front tires and that would seem to be the best rather than picking them up out of the beam. I haven’t tried footbrake since the first two runs on the car. I’m also going to try and compare the difference. I have bias tires on the car now and 60’ 1.37-1.39 but plan on switching to radials. Is the leave comparable or am I going back to the beginning?
