To your engine, nitrous is simply a more convenient
form of natural air. Since an engine is only interested 
in the oxygen contained in that air, nitrous provides a 
simple tool for manipulating how much oxygen is packed in 
with the air. Nitrous oxide is a mixture of two nitrogen 
atoms and one oxygen atom, chemically bound together to 
form an N2O molecule. The nitrogen is actually an inert 
element that won’t burn by itself. The power created with
a nitrous oxide system comes from the additional fuel it 
sprays, along with the extra oxygen it brings. If you left 
the additional fuel out of the equation, the nitrous oxide 
would just speed up the rate at which your engine normally 
burns its fuel and that would lead to a catastrophic 
failure. Since nitrous really just allows your engine to 
burn a greater quantity of fuel and oxygen in the same 
time period, you’re able to add tremendous power without 
making radical changes. 
	There’s no trick to using nitrous oxide. It’s 
really no different than if you were to install a blower
or turbo, or to simply swap on a better breathing intake
manifold and carburetor. In fact, your engine will run 
like it’s on steroids, because it’ll be burning an amount 
of fuel and air that only a much bigger engine normally 
could. Understand that the air we live in is made up of 
around 78% nitrogen, 21% oxygen, and 1% other gases (at 
sea level). Nitrous oxide is formed by combining two of 
the major elements of earth’s natural atmosphere into an 
easily injectable mixture to burn extra fuel. It’s only 
when you don’t inject the proper mixture of fuel and 
nitrous oxide together that you run into serious trouble.
Unfortunately, as with all power adders, there’s a 
practical limit to how much you can run into before you 
reach critical mass and self-destruct.
	The important thing to remember when running 
nitrous oxide is that too much is NOT a good thing, and 
small amounts of the stuff can go a long way.
