spraying techniques...

[nate22]

...for an auto? :) don't laugh..i'm damn serious!!!

[GT-Nitrous]

for an auto.. setup your WOT switch and uh.. just smash the pedal down.

[Luni420]

autos are better (in some cases ) for forced induction because :

1- you never miss shift
2- unless your auto slips you never over revv
3- you can spray / stay at full boost between gears
4- you can build boost / spray off the line
...etc

nothing special about nitrous on an auto (That i know about) ... just install it to the WOT switch, maybe add an rpm switch so you don't spray at too low an rpm (if your auto can hold the power you shouldn't worry about the top rpm / redline) ...

if you want to upgrade your auto, then alot of DSM guys upgrade their valve body (controls oil pressure) and couple that with an extra oil cooler because modifying hte valve body has a side effect of making hte oil run hotter

Have fun, be safe

oh and turn the OD off : ) ... you don't want to spray that gear

Nice information just one question, what is a WOT switch?

[larryd]

Its a switch that you wire up to your throttle wire so that when you engage the pedal all the way to the floor (ie WOT) the switch kicks on and activates whatever solenoid you have running off of it.

oh ok, thanks

discuss?

[Luni420]

in general 5th gear (or 6th on the GTS) is the overdrive gear

in automatic cars there's also an overdrive gear

the overdrive gear is the smallest gear in the transmission , and it's where the engine is under the most load trying to turn the wheels at a faster rpm than the motor at the cost of torque (Which isn't necessary when you're moving at 60mph)

most nitrous guys will tell you not to spray in your overdrive gear to lengthen the lifespan of your motor, and prevent any damage to your transmission ... I don't know if the celica has an overdrive button or a 'sport' setting ... if you do then turn the overdrive off / turn your sport setting on ...this will prevent the transmission from shifting into it's cruise gear...and should also make it shift more agressively which is good too

I hope this made sense (i know people that have sprayed their 5th gears though and haven't broken anything ...it's a personal judgement call ... but we still advise against it anyway)

"WOT"= Wide Open Throttle

Now my noob question is...The WOT switch is just a toggle switch correct? I can turn it off and if I floor my gas pedal it won't engage the N2O?

[larryd]

You are correct as long as you have a on/off main switch for the nitrous. Basically the on/off switch sends power to the WOT switch which then checks for WOT which then sends power to the window switch which checks to make sure your in the set RPM band and if you are it turns on the nitrous/fuel solenoids :)

[Luni420]

there's an arming switch, if the arming switch is off you can never spray

with old kits you had the arming switch and a push button switch ...

and so only if the kit is armed and the button is pushed it will spray, this doesn't stop it from spraying if you're armed and sitting at a stop light ... at idle ...so you can see how alot of people accidentally blew motors

with new kits you get an arming switch and a WOT switch so that only if you are armed AND at WOT does the kit spray, if oyu're not armed it won't spray if you're not at WOT it won't spray ...so this way alot less cars died since it only sprays when you want it to ...you can't accidentally be at WOT : )

The latest way of doing it is you run the arm signal to the WOT switch and you run that signal to the window switch and you run that signal to the Fuel pressure safety switch and you run that signal to a 1st and 5th gear shutoff switch (if you like ) ...etc
and so only if you are armed AND at WOT AND in the right rpm range AND haven't lost your fuel pressure AND not in 1st and 5th gear , the kit sprays...if any of these things is false (you let off the throttle, your fuel pressure drops, you go into redline beyond the settings of your window switch ...etc) the kit will not spray or it will stop spraying

And so there you have it ... you can wire up as many conditions as you want in series and only if they are all right will it spray....

If you want an OR in your logic instead of an AND you wire up stuff in parallel

like you can have the kit wired up using a WOT automatic mode or a WOT push button mode

so you have Arm -> Wot-> window -> solonoids
or you can have push button -> WOT -> window -> solonoids

etc
so if you're armed at wot and in the right rpm range it sprays
or if you press youre little 'boost' button, while at wot and in the right rpms it will spray ...so you can pulse the push button for traction if you're doing launch type racing ...if you're just doing highway pulls you can use the arm button and focus on your shifting ..etc

EDIT : (sorry larry i guess we were posting at the same time)

[larryd]

NP.. yours is just alot more explanitory :)

[PhatCellyGT]

damn, that's alot of wiring/connecting to certain things. I'll have to do it the "safe" way since I'm such a noob. It's gonna be more for show purposes anyway

[TrDCeLiCa85]

If you floor your automatic off the line using the WOT system won't your wheels spin causing you to blow your motor? Don't you have to get off the line a little bit and then floor it?

[larryd]

Wheel spin does not cause you to blow your motor. You do not want to spray below a set rpm of like 3000rpm though.

[GT-Nitrous]

the wheels have no effect on a motor... :wtf: like larry said, you can damage your motor if you spray below 3000 rpm. for the most part, if you use nitrous in 1st gear, you'll get some wheelspin. i lost to a freakin V6 auto camaro when i first got my kit because i spun my wheels forever in 1st.

you can always turn the WOT switch on whenever you want. launch in 1st w/ it off, get your traction then flip it on after you pass 3 grand.

[TrDCeLiCa85]

So when you're launching and your at 3000 rpm, u should hit the siwtch on and it'll just kick in?

[ohwhatafeeling]

Larry...if I may ask...what nitrous set-up did you have and how did you set it up (what kind of switches did you have)?

[larryd]

I actually had a NOS kit and a Nx kit, the Nx kit was never fully installed though due to my accident.

I had a WOT switch, a Mallory window switch, and a on/off main switch.

[ohwhatafeeling]

Ok...so you would turn it on, then when racing only at WOT, you'd push a Mallory button and be gone? ...or once you hit WOT it would be spraying automatically. And if it was a button, what gear did you push it in, at what RPM, and did you have to push it for each gear? Sorry about all the questions, but I've been thinking about this for a long time but nobody has any answers around me, ao I'm seeing this thread as an opportunity...

[brandon6976]

sorry to highjack I just got my nitrous kit on my Auto GT-S ..

So is it alright to use it in first. I've heard people say you shouldn't use it in first??

any comments on that .. any truth to it ?? or is it just the 3k rpm thing ?

[larryd]

I dont know about the auto, you have to ask someone who has an auto...

Regarding the rest of the questions. My nitrous kit had an on/off switch.. First thing I would do is switch the kit to on arming the nitrous kit. Then when and if I hit WOT the switch would send power to the mallory window switch which would check to see if I was in the set RPM range and if I was it would spray the nitrous/fuel.

I sprayed from 3-8000 in every gear.

[ohwhatafeeling]

sorry to bring this to the top again, so, when launching, you would be slipping the clutch and technically not at WOT so you wouldn't be hitting nitrous, but the instant you caught grip and floored it, you'd be spraying and thus peeling out like crazy in first and then shift quick and be in second spraying and so on .... ??? ..thats kind of sweet, but I need to learn how to hit lift in second before I do something like this...lol
