Anyone running a two-step on a six speed?

I've heard it can be done but i've never seen it.

Thanks

Not too hard to do. Disconnect the wires from the start safety switch that's under the clutch pedal and splice them together. (Be aware that the car will now start without depressing the clutch!!!) Take the top off the console around the shifter. Get a small micro switch and fab up a bracket that will let you mount the micro switch to where the lever is depressed when the shifter is in first gear only.

Run a hot wire to a toggle switch. From the other terminal of the toggle, go to the shifter micro switch. From the other side of that, go to the clutch pedal switch. From it, go to the 2-step. You can also tee off the wire to the 2-step and connect it to your line lock. This way, when the toggle is on, the tranny is in first, and the clutch is depressed, the 2-step and line lock will be on and will also keep the car from rolling out of the beams. I ran mine like that for years.

A note on NHRA/IHRA rules. If a car is originally equipped with a start safety switch on the clutch, it must work. I don't really think they ever check them in tech, though. If you're worried, you could always use another micro switch on the clutch pedal instead.

I sent you an email with a small wiring diagram.

 

Thanks!

Could you elaborate a little more on how this works with the clutch.

I got the electrical side down just wondering how the clutch is used. Are you manually depressing the clutch like normal and holding it or is there a way to keep it depressed and then released by using the two-step ? Like a trans brake in an auto I guess.

Edit: I think i see what your doing now. The safety switch is used as the release of the two-step?Correct?

Thanks

wow thats pretty neat! electromagnet clutch release.....

I skimmed through the post, and looks like you are launching off the clutch pedal.

Wire the 2 step into the clutch safety switch so it disengages when the clutch safety circuit is broken, you could do the same for the linelock.

At the start:

push clutch in, 1st gear. Flip the switch to activate the 2 step and linelock. give car gas. release clutch pedal to launch car.

That is how I am doing mine, releasing the clutch will deactivate the 2step and linelock, and activate the nitrous.

Just make sure you use something like the recommended microswitch on the shifter so that the 2step doesnt become active when you shift it You could do a pushbutton or rig up some type of speed sensor that deactivates the circuit after 10 mph or so.

 

Travis,

I wrote up a diagram with what you want to do I think. Launch the car by releasing the clutch pedal, while your right foot is on the gas.

The diagram has a master "drag race mode" switch, which will put the 2 step, linelock and if you want nitrous all active. I included a seperate switch for the linelock, seperate of the "drag race" circuit, in case you need it for that occasional burnout contest! I can also put a seperate one on the 2 step if needed, as well as the juice.

This setup lets you keep the clutch safety switch, and you will need to find a suitable way to tell the circuit that the shifter is in 1st gear, either by a speed sensor or a manual button you press while still in first gear. I am not sure the shifter mounted button will work properly as there is a split second where the shifter will be in first with the clutch on the floor, but if you dont push the clutch all the way to the floor, no worries

Let me know if you want it, i can put it on the PC

 

i just wired my two step today... it's all kinds of fun, can't wait to get back to the track to try it out

Yes, I'd like to take a look at it

Thanks!

Just like Serene said. Stage car, clutch in and brake on. Flip switch. Take foot off brake, slam the gas. Release the clutch on the bottom yellow or whenever you normally leave on the lights. No problem with the 2-step hitting on the first to second shift. Since you are yanking the shifter to second gear and stabbing the clutch at the same time. Mine worked with no problems.

If you want to leave off a button like a transbrake, you can get a clutch line lock and shuttle valve from McLeod. That's what I'm currently running with a TAG Systems delay box. But, make sure you have everything beefed up. It really hits hard, since it's like sidestepping the clutch pedal. I've blown 9" Ford pinions out the front of the housing.

I can make a diagram to wire that up to if you ever want to try it.

 

I almost forgot. You might want to put another toggle switch between the line lock and the 2-step so the 2-step won't kick in while doing your burnout.

 

Ya i included a switch for that. Just keep the "drag mode" switch off until you are staged.

 

can someone host it?

 

Another thing I just thought of for the N2O crowd. You could wire a relay into this to activate your N2O when the car leaves. You can get relays that have both normally open and normally closed contacts. In other words, the relay will also turn things on when de-energized and off when energized. When the 2-step turns off, the relay will turn on the nitrous. ARC makes a small time delay that could also be used to delay the nitrous hit from .1 to 1 second after the leave. Jeg's has them for about $35.

 

send it to me..I can.
