Hey guys, Just wondering what most people did for their nitrous switches, im using a Zex wet kit so its a WOT dealio.

Ill be getting a pre-98 center console soon so i was thinking maybe in the DIN slot, but im just worried if ill be able to flip the arm switch while dragging (dont want to spray in 1st).

Also wondering where you guys wired the power to for the switches. I was thinking maybe the cigarette lighter.
Wire the switch in to a reverse fed relay, powered by a momentary hold button.

Place the button underneath the shifter boot and mount with a bracket in a way to have it pressed in while in first, but released in 2nd or higher. Then, if you are in first, the button is depressed, which will kill power to the relay which feeds your setup.

once you shift out of 1st, in to 2nd or higher, the button is no longer depressed, the relay is energized, and your setup is powered. go WOT in 2nd and it automatically is spraying. no hands off the wheel, or the shifter.. tada.

Would that even work with the short throws of the Steeda? Id think it would be a little tough. Its quite ingenious tho.
but then you cant spray in 1st.........lol

not spraying in first= a lose against anything that isnt FWD, like our platform
The answer was tailored to HIS particular situation, platform, and desires. he specifically stated he does not wish to spray in first.

thank you for your opinion, either way, I guess.

Spraying in first=blown diff and way to much wheel spin, i already have traction problems at the track let alone with a full 75 shot of nitrous in 1st gear. Ill probably be spinning in 2nd, if thats the case then ill just make it a end of 2nd/3rd/4th gear deal.
i see what you are saying. wheel spin is a problem if i spray from a dead stop but i roll out a couple feet and then hit the button, with minimal spin. i could possibly already have a LSD though, because my car leaves 2 black marks when i burn out and it doesnt wheel hop like everyone else explains. the car has a fair amount of miles on it and the transmission shifts unusually tight... so i am suspecting it's been rebuilt. either way, your plan should be to spray in 1st and make your driveline good enough to handle it, otherwise you are wasting the potential of your nitrous setup, IMHO


ps. i was just playin anyhow, good luck with your setup
To revise the possible workings with a steeda, modify the setup to be a magnetic switch. mount the switch on the outer edge of the interior (bottom right, where the bottom of the shifter would be in first) and place a two wire powered coil (they are TINY) on the shifter itself. Whenever you go in to 1st, it will pull the mag.switch open and kill the setup.

That would fit in most any space.
here's what i did (easy and obvious!)

where the WOT switch normally is wired in the system, i got a button shift knob (B&M gone in 60 seconds style baby!)

and wired it right in there. push button, and there it is. i have a MSD dis-4 ignition that i have a step retard wired in also. as soon as i push the button the ignition retards to my set amount. when i let off the button, the timing stays retarded for 1 second, then goes back to the stock timing curve. its a real sweet setup, as long as you can remember not to hit the button before your at WOT.

The Zex kit is a WOT kit, the button would work tho, but its not what im going for.

What about the other switches (bottle warmer and purge button)

The only problem with these setups is they can become frail with the amount of stuff ill be doing with the car, plus its not really reliable.
I'm going with a MSD digital window switch, so I can still spray in first, with the car hopefully halfway hooked by then... Actually, at 3400 RPMS and WOT, if I don't have some semblance of traction, it's time to start changing the suspension, lol. Also, 90% of purge kits come with a button, so I wouldn't worry about that. What I WOULD do is hide a "master" power switch somewhere... don't want valets finding the "happy button".

Purge kit didnt come with a button

And Valets.. HELL NO.

I cant remember who, but someone on here (Brapple) has a pre-98 center console with some switches in place of the stock pop-up cup holders.
It all depends on how much power you already make in 1st gear. If the car is a weak dog then I'd spray in 1st, but any 3L and above it wouldn't be worth the nitrous waste and tire wear. Spraying in second if it is a moderate shot and then with a progressive feature would be good and then let it rip in 3rd.

At the track i slip BAD, On the street i can probably run it in 1st but id like to stay away from needless wheel spin. Ill just do some trial and error to see what i like best, for now i just need to find a way to get some switches working.
something like this would be cool



But instead of aluminum id try to get it black Plastic.
