Banjo why not just use a choke cable? Many do. Oh glad you back on here.

WOW!!! this train really went off of the tracks!
I always wanted to try using an MSD window switch to see if it would be accurate enough to turn the light on and off with chips set close to each other.
Anyone try it?

On the manual lauch RPM setup it has to be spring loaded to be legal, doesn't it? I've seen people do the choke cable deal and forget to push it off, lots of fun at the shutdown!

It usually does, here.


You have to put in the effort, to get anything out of it.

just sayin'


What Ed has in his car and what I made only controls the staging rpm. It is not an SLE by any means. No different than using the choke cable on a holley carb. Just bumps the idle up to a pre-set RPM.

I used a choke cable with a solid stop in my first racer, had it mounted where I could find it easy in the dark. It worked like a charm.

a choke cable is no comparison to this two stage RPM controller...

Eman what do you use for a brake pressure switch? and how is it wired?

I use a simple brake light switch that works on pressure, I can't remember the part # but I can look if you need it. It's a simple 2 terminal with 1/8" pipe threads. I know Jegs sells them but I bought it at the local parts store. Use bullet connectors that just push on the 2 terminals. I run 12v to it which activates the 3 step when I'm on the brake. If you use the brake at the finish line you have to figure a way to shut it off or it will stutter at the finish if you scrub the brake.

Here is the hydraulic (brake) pressure switch I have used for many years, at tracks that allow 2-steps/launch RPM limiters in footbrake/No-E.
Hyd Brake Lt Sw BWD S194
Probably the same one E-Man uses, has the male bullet connector pins. Borg Warner S194. Less than $9 and lifetime warranty at O'Reilly. I think it was originally spec'd as a replacement for a '79 AMC Spirit.
I plumbed it right near the M.C. - Added a 6 inch long brake line from M.C. to a brass "T" fitting with 3 female ports on it. Then attached the original brake line and switch. Make sure you bleed all of that air out, or any remaining bubbles will compress, and the "decompressing" of that air after you release the brakes will slow your reaction times. Wink

That's the switch I use. I use a Hurst line lock and it screws right into it. I used to have a toggle switch to turn it on and off but it was a pain. I have a transbrake button on the wheel that I wired in the circuit so if I press it the brake pressure controls the launch RPM. Take my finger off and it won't stutter down track. I can unplug the button from that circuit and plug it into the TB circuit if I want to use the TB on the bottom and can also plug my delay box in and run top.

any electric/electronic device that controls launch rpm as in 2-steps are not legal in a true footbrake class as contested in the Summit ET Series here in NHRA Division 1.

The only way to eliminate rpm creep is to remove your foot from the equation and replace it with your hand, mechanically holding the throttle open against a stop.

You guys can't hold your car at the proper rpm when staging ? Maybe you need to take up chess or something Big Grin

NOT true foot brake if you need a crutch, might as well put a button in it.

clueless comment^^^

Yes true. I've been competing in footbrake for 25 years and never have had any issue holding my cars at stage rpm. The reason why I and many of my competitors installed Dan's controller was to...

1. bump in at an RPM lower than stage RPM.
2. minimize the time we are on the converter once staged. In my case, at 4000+ rpm.

So a delay box is a crutch?

In Div 1 NHRA using that style of launch RPM device does it have to be spring loaded so you have to hold it or does it lock and you have to release it?
