I am wondering about doing this. Anyone have pics or know who sells such things?

Thanks

 

You have been wathing too much fast and furious.

EDIT

get a shifter with a button like the people with fast cars

 

Get a wide open throttle switch like the people with the faster than fast cars do.

 

Get a progressive controler like the people with the faster than fastest cars do

 

get a shifter mounted progressive controller with a tps sensor like the people with faster than the fastest fast cars beat the supar fast cars with.

Seriously get a TPS setup and an RPM window switch.

 

ROFLLMAO. I was afriad I would start a flame war with that post but this is actually funny

 

Ok back to my ORIGINAL question.

Anyone mount a momentary button on their steering wheel? And if yea, what did you use? I am trying to come up with ideas to put it on my stock steering wheel.

And no, I do not want to setup a window switch , etc..etc.. This is a totally hidden Nitrous setup and I want to keep it that way..

:lala:

 

If it's hidden, a steering wheel momentary button is going to all but give it away. You can use horn button as the momentary switch. You can use the horn cam so that cheesey wire doesnt wrap around the steering wheel when you turn. The horn only activates the nitrous when the nitrous is armed by a hidden arming switch. You can still use a window and tps sensing switches with this setup and be completely stealth. I just prefer a shifter momentary switch but really there is no need for a momentary switch at all with a window and tps switch. Introducing human error will kill your consistancy.

 

The window switch they are talking about is tied to your ignition - it won't let the nitrous into the engine unless you are in between a certian RPM "window" ie between 3000 and 6000 rpm - It is a saftey net to keep from blowing up your engine - not a power window swich modified to activate the naws. And A button on your steering wheel would make everyone that has seen fast and furious say "You got naaaws?". If you really want buttons on your steering wheel it isn't hard to du just drill a hole. I believe monty has swiches on his wheel for shifting. Search his name and look on his web site.

 

I know you meant a window switch, not a power window switch.. :sillylol: .. I've setup Nitrous on other cars before but if I use ANY of those devices it is very easy to tell if you are runnign nitrous. The way it is setup now, unle syou take the intake itself off you can NOT tell I have anything, even if you look closely all over the engine.. That is why I do not want to mount any tps switches, or throttle microswitch or rpm window switches.
Right now the horn button is the best idea, but pushign the horn while screaming down the 1/4m is not the safest thing to do either. that's why I wanted a push button.

Mayeb something that can be clamped to the steering wheel as I've seen somewhere once in teh past. The guy took off and put it on within a few seconds. It had a metal clamp that could be snapped on the outer steering wheel piece, and he put it right by his right tumb. Thsi way he coudl push it easily..

 

My TPS switch and RPM window switch are hidden under hush panel under the dash. They are completely invisible. There is no issue with the electronics or wires being seen. The wires tap into the ECM pigtail, not under the hood. I'm telling you that this is the single best setup you can run for consistency and safety and invisibility. Forget the momentary switch...it is completely unneeded. The only switch you need is a hidden arming switch (in the ash tray for instance).

 

well, pertaining to the original post...you could buy just about any momentary switch at radio shack, and if you have a Grant steering wheel you can mount the button in one of the holes. theres either 2 or 3 holes on each spoke on the wheel, 3 spokes total. plenty of switches

 

Hmm good point.

I haven't thought of splicing into the harness itself by the ecm to put on a window switch or tps switch.. I'll have to look into that..
Only drawback I hear of window switches is that let's say you go wot and it is spraying nitrous in teh engine, but you decide to let off the gas slightly for whatever reason, and you are still in the window switch 'on' window. You'll go lean and risk doing damage don't ya?

 

Couldn't tell if you were dumb or not... I figured i would just tell you want it is incase you (or anyone else reading this thread) didn't know what a window switch was. shrug

 

NO, the window switch and WOT TPS switch are wired in series. That is, the engine has to be in the RPM window AND the throttle has to be fully open - simotaneously. One or the other will not trip the nitrous on, only both at the same time will. In the situation you mentioned, the TPS switch will immediately deactivate the nitrous even though the RPM is in the 'on' range for the window switch.

 

Hmm, I see what you mean but a TPS sensor stays at WOT voltage above 3.69v which is around 70% throttle). So if you let up off the gas a little bit, the wot switch and tps switch still think you are going ballz-to the-wallz unless you go get off the gas about 1/2 way don't they?

Maybe I'll buy a set of those and play around with it just to see..

 

No, you can adjust the TPS switch to exactly what throttle percent you desire it to turn on. I am using Matt Paul's ATPSS and have mine set to turn on at 99%+ throttle.

 

i kinda like how the Zex kit works and its pretty easy to make "hidden" why not put the trigger switch on the gas pedal under the dash, no one would see that and it would work the same way as bein on the throttle body.

 

I think using the window switch and TPS switch is the best idea, but if you really want a button on the steering wheel, maybe you could use the steering wheel and steering column from a T/A with radio controls on the steering wheel. Wire whichever switch is easier to reach to a latching relay to trigger the nitrous.

 

Best way I've seen to trigger it in a hidden way is to mount it like an old bright/dim switch from the days they were on the floor. Get a momentary switch and mount it to the floor and just rest your foot on it to trigger the nitrous. Wire it through the hidden arming switch of course.

 

These are all great ideas and appreciated, but my issues are :

If I set the Nitrous to go as soon as I go WOT, I will be spinning 1st and 2nd and not have ANY traction. I have a hard time NOT losing traction already with the car with 275's on the back, so I just want the Nitrous to 'hit' after I'm in 2nd after 2.5K or 3K rpms.

I will install an MSD window switch, (or maybe just a plain RPM switch as I don't have to worry about an upepr rpm. I should only see 5000rpms at the end of the 1/4m, and my tranny shifts at 5000rpm's stock for now. So I am spraying through the shift.

I decided to just modify the shifter handle and put in a momentary micro-switch.. We'll see how it runs..

now to my next thing.. I have to find jets that fit in the NOS Pressure Reducer 'Tee' that goes to the AFPR. The normal sized jet's don't work. Looks liek I might have to call NOS for this one..

G'nite everyone.

 

just because you want to be hidden doesnt mean you should overlook saftey.

for the WOT switch, i would just place a micro switch on the gas pedal arm under the dash. it cannot be seen without takeing the lower panel off, and it adds a degree of saftey you need.

for the window switch, there are already 2 tach wires under the dash.. one for the computer and one for the tach

for the arming switch, a option i would consider:

somtimes the best place to hide somthing is in plain sight. get a defroster switch from a car with that option, and then use that for your arming switch...

 

<---- bottle heater with foglight switch and purges with momentary defrost switch (all are factory switches, my car was not equiped with these options...)

 

well if ur investing money into a nitrous setup itd be obvious to invest money in everything behind the engine as well, u mentiond ur gonna spin 1st and 2nd, shouldnt have or intend to get soem traction aiding parts on this car? if u dont have ur cruise control in u can use the accel button for purge, on/off for a master switch. i like the dude with the formulas idea for the fog and defrost switch, definitly trick.

You can hide one somewhere else besides the sterring wheel...

BUT an aftermarket steering wheel might work.....

 

A little of topic but will that work on a stick car

 

Yes. If it were me, I would further improve the system by adding a clutch switch in the series. If I were drag racing a manual, I wouldnt ever let go of the gas and hence would want the clutch switch addition.

 

not entirely possible. If I try that with my setup the engine overrevs and blows black smoke...

 

I mounting one to my steering wheel so it only activates when the wheel is turned all the way to the right or left so that if I get squirrely at the track I wont have any second thoughts about trying to save myself... :sillylol:

 

you must beable to do one hell of a donut! :sillylol:

 

How about the back of the steering wheel, like an indy car shifts??? the right could be armimg, and the left could be the nitrous switch???
