Brake Pressure Switch for launch control ???

There should be a micro switch that PPP can supply that mounts opposite side of the Netural safety switch. It's triggered by the same rod. No external bracket and switch required then . Very clean and they provide a screw on connector wiring harness same as the Safety switch hasness .

Just curious how much brake pressure do you use at the starting line? I have seen a lot of data and have never seen brake pressure over 4-500 psi (on 160 mph plus cars). I would think anymore than that would lock em up bad at the stripe.....

Set @ 800 and release @ 200 generally on our stuff.
120/125 MPH Stockers.

Anyone hook up this setup using a Turbo Action Cheetah with a reverse pattern 3 speed trans ?

I'd like to try it and making a switch to only work in low gear looks like a challenge.....

I haven't done it with a reverse pattern but I think it could be done fairly easily by mounting a momentary, lever micro switch on a bracket attached at the trans pan rail or in tandem with the shift cable bracket. Switches like these are available in short or long arm for less than $20. Should be able to activate when the shift lever arm is in low gear only.

Easy to do. I use a neutral start switch I got from turbo action.

Thanks, that is a great solution. I didn't know if it would work

I'm an old pure foot breaker but always open to trying something different.

When I owned this car in 2006 I did install a 2 step button switch and low rpm adjustable chip but never used it.

It was not comfortable to me leaning hard on the brake pedal and using that hand operated button.

Using the brake pedal with a pressure switch sounds more appealing

I have taken the shifter apart at least 4 times to do various things.....one more time can't hurt....

The problem with that on a reverse pattern is the shifter or lever is moving toward the switch as you upshift. The switch would also be in the way going back to N-R-P

I've made switches like that on other cars but the shift pattern was forward.

I'm sure it can be done but it takes some thought and fabrication

The built in neutral start switch posted above is a good solution

If you're just bracket racing and not class racing I did it an easy way. I put a trans brake button on the steering wheel. If I put my thumb on the button it would energize the circuit for the brake pressure switch. After launch I just moved my thumb. On 3 speed GM transmission you can use a pressure switch on the transmission pressure port.
