2-Step with a Stick Shift ONLY please !!!!!

[Aubrey N Bruneau]

I just went through a number of old threads on 2-steps.
I think my head is going to explode !
Brake pressure switch ??????? WTF is that for ?????

Anyhow...
I need to get my 2-step wired into my car ( along with the line-lock that I still haven't installed ).
I need it to hold about 6000 RPM while in first gear, clutch pedal depressed...
But once I leave... allow me to shift around 7000.
How the heck do I do that ? !

I'm expecting a big education here !

Put a switch on the shifter that over rides the two step. Probably will be where you have your line lock switch now.

Brake pressure switch on a stick shift car helps you be consistent. When you stage the car, find through experimentation what is the minimum safe brake line pressure necessary to hold the car still while staged. Then the release time of the brake system becomes a consistent factor in the "leaving event". The more pressure you build into the brake system, the longer it takes to release it.

Since you currently do not have a line lock, the brake pressure switch is not an issue, unless you have three feet.

This is easy, you need a switch that activates only when the clutch is pressed completely to the floor, I use the arm type switches the chassis places sell cause they're easy to adjust. You can use this set up cause no one presses the clutch completely to the floor on a gear change, believe me I know it works. I've wired up a relay in the past hooked to the line lock that deactivates the line lock on clutch release that way you have the line lock holding the car in the beams. Joe

See figure six. That allows you to hook up a line lock and a clutch pedal switch on a stick car. Once you stage, and step on the clutch, release the line lock button, the switch on the clutch pedal holds the line lock, holding the car on the starting line until you let the clutch go.

Wow, thanks Alan I've never seen this before basically how I had my stick car set up. Their schematic is much easier to read than my "art work" thanks for the link guess I never thought to look there.This looks very easy to set up. Joe

It's easy enough that even I could do it! It takes a lot of opportunity for "stupid" away from the driver, not enough to make up for my having not raced a stick car in near 20 years, but it helped. We had it set up on an MSD 7AL-3, it worked like a champ, especially when the 220# of ballast that was holding the steering wheel did its job. Which was not often enough. I think I made a dozen passes in that car in a year, only 4-5 of them were decent.

aaaahh... but is it enough ?
I tend to seize every possible "opportunity".

Thanks people !
Now, with a couple switches and about 8 wires to install... the question becomes...
will I have enough time between now and May, to figure out how to do it ?

This may be a slightly silly question related, but my green challenger that we put the stick back into has one of those RPM activated switchs in the glove box..and a msd 73al with a 3 step...prior owner had a transbraked auto in it, and we couldn't figure out what the rpm activated switch was for....had a 6k chip in it and the car would lay over at the line sometimes so I threw a 7200 or 7400 in it, still layed over every 2-3 runs.....might have been a fuel pressure issue.....I ended up doing some wall quality control testing with the RT at Napierville so this thread is quite helpful!

thanks

Well you're the one living north of the Arctic Circle, man.
