I have experience with nitrous. I had an 88 EF Civic with the DPFI (1.5L)all stock, no bolt ons, no timing, no plugs. just exhaust headers and full weight reduction. I ran a 65 shot on that all day and never had any problems. I was a Honda only guy then. Now I have my NX and im wondering if I ran a 50 (wet shot) on stock timing and fuel components if the engine would be safe. Its a Zex wet kit. Any input?
OK I looked all around the forum and on the internet, but what I cant find is how exactly nitrous works..
I know it adds more air and cools for more HP, but the part I dont get is when you spray your shot, either wet or dry, it adds 'X' HP...
However what is not explained is how long the shot lasts for? Does it last for a certain amount of seconds for a button press.. do you continuously press the button for like a run down the strip or is one press enough to last that long?

There are precisely cut jets that you use to control the amount of nitrous that goes into the motor. As long as your hitting the button/controller it will spray that amount of nitrous which will make the given amount of hp.

Nitrous actually makes the air that it contacts, passing through the intake, more dense and dense air takes up less space so you can get more air into your combustion chamber, thereby creating more hp. More air + fuel = more power.

We'll stick with spray controlled by a button (as opposed to a WOT switch) since that's the example you used in your question.
As long as you have the button depressed, and the system is spraying nitrous, you'll reap the benefits. Once you cease spraying (in this case, pressing the button) then you will cease feeling the gains that nitrous produces.
So to answer your question specifically, yes, if you're running a strip then you need to have the button depressed the whole race (only when you're at WOT and at appropriate RPM's).
Basically ... one press of the button doesn't get you a race worth of nitrous gains. The nitrous has to be actively spraying for you to get the benefit.
In looking at the link above the product description doesn't mention a WOT switch as being part of the package, but I'd imagine that a follow up call to JWT could answer that question for you.
In reality, you could run their system however you choose. The wire for the solenoid activation can be run to either a button or to a WOT switch (that you could position near your throttle cable in the engine bay or on the floor below your gas pedal). It's really up to you which form of system control you want to use. Personally, for those less experienced with nitrous I'm more apt to recommend a WOT switch so you don't run the risk of pressing the button too soon or holding it down too long and blowing something up.
