I honestly understand the use of the gases but how is it controlled? When you squeeze do you do it in shots? Someone please explain how it works, how to use, how it's not supposed to be used. Can't seem to find a good article on it.

Damn, I could write a book on this, but here's my short answer:

The nitrous in controlled by solenoids. There are wet manifold systems and dry systems. In most cases, the nitrous line is jetted directly into the intake right before the throttle body.

Nitrous should only be used under WOT. Most systems have protective interlocks to prevent accidental use if you're not WOT.

I've seen NOS used with driver activated buttons and also with acclerator switches (you can set them to spray ALWAYS at WOT.)

My best friend owns a Supra Turbo w/NOS. His car is modified big time and puts out over 500 HP. One of his main problems is that the turbo (he's single turbo) is so damn big that it takes forever to get full boost from a stop. To cure this problem, he added a 75 shot that he had only planned on using off the line. After that, his turbo would be at full boost and the NOS would not be needed.

Well, after he got used to the car running low 12's on street tires, he wanted to see if he could hit 11's by using the NOS all the way thru the run. It was quite a bit of stress on his motor, but it held up and he did hit 11's. NOS is pretty amazing stuff. If properly set up and used, it can really turn any car into a monster without any fear of engine damage.

I know this is a jumbled up answer to your question, but it's the best I could do right now......

Umm...here is the technical answer.


You see NOS is a gas, Nitrous-oxide to be exact. You get it installed for about $800 and then when you floor your car you push a little button inside which releases the gas. And heres the fun part...when you press the button, your car goes WOOOOSHHHH (damn its fast!). Since you paid $800 you need to know no more than that

I need to stop being a smart ass today, already got myself into trouble at work once today

What happened? Did they kick you off drive-through and put you back on fries? J/K

Flame away but you left yourself open for that

I found a more technical answer. Sorry ken...

from www.howstuffworks.com

Question 258 talks about how Sodium Chlorate acts as a way to store oxygen. You release the oxygen in sodium chlorate by heating it. It turns out that nitrous oxide (N20) works exactly the same way. When you heat nitrous oxide to about 570 degrees F, it splits into oxygen and nitrogen. The injection of nitrous oxide into an engine therefore means that more oxygen is available during combustion. Because you have more oxygen you can also inject more fuel, and that means the same engine can produce more power. Nitrous oxide is one of the simplest ways to provide a significant horsepower boost to any gasoline engine.
Nitrous oxide has another effect that improves performance even more. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air. When you reduce the intake air temperature you increase the air's density, and this provides even more oxygen inside the cylinder.

The only problem with nitrous oxide is that it is fairly bulky and the engine needs a lot of it. Like any gas it takes up a fair amount of space even when compressed into a liquid. A 5-liter engine running at 4,000 RPM consumes about 10,000 liters of air every minute (compared to about 0.2 liters of gasoline), so it would take a tremendous amount of nitrous oxide to run a car continuously. Therefore a car normally carries only a few minutes of nitrous oxide and the driver uses it very selectively by pushing a button.

Hey, that's good info, but I think eclipse said that he understands that aspect. He's looking for info on how it is used and activated....... Do they have answers to those questions on that website?

That site doesn't but I did a little searching and found www.nitrousinfo.com. I gave it a once over and I think it has everything you need know about NOS. Solenoid diagrams, FAQ's even a video of someone's ride backfiring with NOS in it. Pretty cool. Check it out.

Nitrous is only recommanded during WOT. It's a constant flow of the gas and not really shots. People use shots to describe how much HP gain the nitrous suppose to give. 80shots = 80 extra hp. There are several ways to activate it.

1. Micro switch which is switch that's triggered mechanically by the throttle body when it's at WOT.
2. A button the driver can press.
3. A electronic device that activates the nitrous when it sees above certain voltage at the throttle position sensor.
