dont think im understanding the switches right

[this is copied from another post...to help field some Q&A]

am going to run a WOT switch for safety so the nitrous isnt activated at anything under full throttle.

now i had been debating between a push button activation or a window switch....but i dont think im understanding the window switch. i realize it creates a "window" for the juice to be used...ex. 3000-6000 rpms....BUT will the window switch automatically spray the nitrous from 3000-6000 or do you still have to push and hold the button? if so what is the use of a switch if you stil have to push the button?

also i heard you can program the window switch to activate at a certain gearing (auto car) but everything i have seen listed in the parts description doesnt mention anything about it.

A regular MSD digital window switch can't hold enough amps to open nitrous solenoids. They just open or close a ground during the widow you set. So you use this in conjuction with a relay to activate the solenoids. I would use a flipswitch to arm the system, I think it's easier than using a button. Basically the arming switch provides voltage to one side of a relay coil. The window switch provides the ground in the "window". That closes the relay which would send a seperate 12v source out to the solenoids to activate the spray.

yea...so id have:

wot switch
window switch set for certain rpm
switch to activate the spray?

so a window switch cannot be set for a particular gear in the auto? i didnt think so but heard that....

i guess with the activation switch arming the system, the wot switch in to only spray at wot, then the window switch in set to say 3-5500 rpm...i could essentially spray in all 3 gears in the 1/4 :dunno:


im trying really hard to learn all this before it gets installed...im a newb.

Lots of switches in a good system lol
WOT switch: allows system only to work during WOT
window switch: allows you to set a RPM window that you want the system to work in
Arming switch: allows you to turn the system on and off
fuel pressure safty switch: allows the system only to work with proper fuel pressure

I'm not nitrous guru, but the window switch seems like a waste to me. What is that supposed to be good for?

spraying continuously at a certain rpm and you dont have to hold a button down to spray :dunno:

i also just found one that has a first gear lock out....something id need right now since i dont have drag tires.

IMO they are good if you are only trying to spray it at a higher RPM range to avoid loss of traction off the line or a a saftey tool to keep from spraying the engine if you were to miss a shift and put it on the rev limiter. If you were to use a simple push button to activate the spray, your thumb could act as the window switch.

I saw a stick big block car that was sprayed down low untill the turbo made boost.

I am not an N20 or boost guru at all either.

That makes sense. Why not just keep on sprayin though :thmbsup:

I like the switch because it reacts faster than you do if you do miss a shift or run past the rev limiter. The rev limiter is just a fuel cutout, so if you hit the limiter you just made the system VERY lean. Bad things happen when a motor is very lean and nitrous is pouring into it. So you set the switch a few RPM below the rev limiter and never have to worry. Believe me the switch saved my ass acouple times when I first started running on the spray. I broke traction and the rev limiter comes real quick. Its just on how safe/user friendly you want your system to be.

i want my system very safe and EASY

this is a post from corral.....seems like exactly what i want
:dunno:



get at window switch...

set it around 3000rpms and then the upper RPM a little before where your car shifts, so it does not hit the rev limiter..

for example since you have the WOT switch in, when you press the gas all the way down the window switch will ground the circuit of the WOT switch at 3000 rpms causing the solenoids to open and then it sprays, You dont have to push a button or anything...just your gas pedal.

Hope that helps

Do it the old school way. Arm the S.O.B. and have a hand held momentary switch. You have an auto so the chances of you missing a gear is about the chance I have to hit the Powerball. Push the buton down when you feel it's necessary.

MSD window switch is not rated to carry the amperage needed to keep the solenoids closed. If you use the switch to provide the ground for the n20 solenoids you are asking for problems. The post will read..."Why are my solenoids cycleing?" If you are using a window switch use it to close a relay

If you are using a window switch use it to close a relay


Thats what I was going to say.:awsome:

Jared is thinking right now..dammit, I thought nitrous was the cheap easy way to make power! I know that's what I was thinking when I put it on the Mach.

:yes:


i wish timmy would reply since he is installing.

[Rodeheaver's]

listen to the words coming from my keyboard!!! Since you are new to the funny gass thing, get a push botton switch(you hold), that way we will set you up with a small hit at first so you can get used to it and play with it and learn to use it the best way you feel comfortable, if you are worried about the rev limiter i can set you up with a rpm activated kill for the juice...

[J-rod]

ok tim....please pm me with what all i need to supply you with.

i know a purge and switch panel. what else?

[J-rod]

thanks tim....ill begin buying.
