Pedal mounted 2 step switch

[NHRA1285]

The new car has an automatic, I know, but what can you do. My question, being I am automatically challenged is: What is the best switch to use for install on the brake pedal for activation of the 2 step? Thanks for any info.

If you're going to mount it in the pedal itself, a Dedenbear adjustable will work.

If you're going to mount it on the pedal arm, in place of the brake light switch, the Biondo/Harrington long throw adjustable will do fine.

I strongly suggest you mount a switch on the shifter that allows the two step to operate ONLY in low gear, as activating it down track is not only illegal, but can be hazardous to you, your engine, and your car.

I use a brake light pressue switch in a port on the line lock solenoid. Let off the peddle and away you go. A switch on the shifter so it works only on low gear is best, no down track excitement.

If you feel you have to use a 2-step, a brake pressure switch is the only way to go. Using a button on the brake pedal is inherently inconsistent.

Personally, I choose to eliminate any such issues, and purely footbrake the car(s), no 2-step.

I use a pressure switch on the 4 speed car but the 2 step is set so high that tapping the brakes does not effect it. The automatic car picks up quite a bit with the two step but I may foot brake it for a bit.

Just my opinion, but I think in order to make the brake switch/2-step work you're going to need a brake pressure gauge plumbed in there too. This way you'll be able to get some consistency with your brake application.

Doesn't that put you on the low RPM chip during the burnout?

Are you saying use the factory switch? Will it work? I have always just foot braked like Michael but I would like the option. I used the switch on my other car once and awhile. I think that it may have improved the et though I never proved it and I liked footbraking better.

Wired correctly, it should be your line lock that sets the RPM limiter to the burnout chip. The brake switch, whichever you use, should set the RPM limiter to the launch chip. Both of those switches "off" should set the RPM limiter to the high side chip.

The factory brake light switch "might" work. However, it is a short throw switch, and not very adjustable. The odds of it working correctly for you are very slim.
