How does nitrous work?

When nitrous is injected into an engine, what happens to make the power? Is it the extra oxygen burning or is it the nitrogen in the mixture heating up? I was corrected by an "all knowing" member on here telling me nitrogen makes the power. Could someone please tell me if I'm right? I know that nitrous oxide is an oxidizer, and it injects oxygen into the engine, to make it's power, am I correct on this? If not please correct me.

I was reading around in the knowledge base and found that link. Its also in the guide to beginning hotrodders (thread is above this one near the top)

I learned a LOT from the link.


Quote:
There are three points. Nitrous oxide is made up of 2 parts nitrogen and one part oxygen (36% oxygen by weight). During the combustion process in an engine, at about 572 degrees F., (on compression stroke), nitrous breaks down and releases oxygen. This extra oxygen creates additional power by allowing more fuel to be burned. Nitrogen acts to buffer, or dampen the increased cylinder pressures helping to control the combustion process. Nitrous also has a tremendous "intercooling" effect by reducing intake charge temperatures by 60 to 75 degrees F. However, it is not this oxygen alone which creates additional power, but the ability of this oxygen to burn more fuel. By burning more fuel, higher cylinder pressures are created and this is where most of the additional power is realized. Secondly, as pressurized nitrous oxide is injected into the intake manifold, it changes from a liquid to a gas (boils). This boiling affect reduces the temperature of the nitrous to a minus .127 Degrees F. This "cooling affect" in turn significantly reduces intake charge temperatures by approximately 60-75 Degrees F. This also helps create additional power. A general rule of thumb: For every 10 Degrees F. reduction in intake charge temperature, a 1% increase in power will be realized. Example: A 350 HP engine with an intake temperature drop of 70 Degrees F, would gain approximately 25 HP on the cooling affect alone. The third point, the nitrogen that was also released during the compression stroke performs an important role. Nitrogen acts to "buff or dampen" the increased cylinder pressures leading to a controlled combustion process.

Your right that is a very good link. You can also try howitworks.com Im sure they have something. They are very good because they have pictures.

Giggle gas will blow up your engine!! Use a turbo/super charger and cleaned up heads and strong bottom end. Port and polish the heads and stroke it.

If you use it improperly, yes, it will. Beef up the innards and dont spray for too long and its harmless.

Your motor will live longer with all throttle no bottle.

Harmless is a relative term, no matter how little juice you use it's still shortening the life of your motor. Then again that's the point isn't it?
