What temp to shoot nitrous?

[cyrez187]

I have a n/t 420a and was woundering what temp should i spray my dry kit at? some say 900 psi?
and should i be hitting it at between 3000 rpm to 4000?

900-1100 psi. The only way you are going to get it that high is with a bottle heater.

I don't understand your first question maybe its cause its early...

You can hit it anytime you want. I would do 3-7k .

well cuz my nitrous kicks in when i hit full throttle, but i dont want it to hit until like 3rd gear at like 3500 rpm sooooo while im drivin i guess hit the switch while im full throttle or does it have to be armed while im not full throttle then hit the switch or how does it work?

2700rpm and above. 900 psi is the bottom I'd go, that's where you really start to lose the full momentum due to lack of pressure.

can u hit the switch while your full throttle?so it kicks in when u switch it on?
and can i hook something up so if my nitrous hits a certain rpm or something it shuts off something for safty reasons!!

i have a fuel pressure switch should i install it?
some guys so its ok as long as u hit at a low rpm u wont overrev or hurt anything?

A window switch will allow you to have it come on and shut off at a certain RPM. You will want a arming switch so it doesn't come on all the time.

I use a armswitch to turn it on/off and I use a push button to spray instead of the WOT switch....works good enough for me!!

Use a window switch and buy some RPM pills for it. You insert the rpm pills into the window switch. Select the RPM you want it to activate, then select rpm you want it to shut off. Nitrous will only work while you are in that rpm "window".

do the only difference between dry and wet is that wet as a fuel solenoid and injects it and dry doesnt? right.
well how do u hook up wet then like do u need a fuel line coming from your tank or some shit for the solenoid to get the fuel or what? any one help me with pics of dry and wet please thanks
