How Does Nitrous Oxide Work?

There are three points. First, nitrous oxide is comprised of 2 parts nitrogen and one part oxygen (36% oxygen by weight). When the nitrous oxide is heated to approximately 572oF (on compression stroke), it breaks down and release extra oxygen, 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.

Why Nitrous?

Nitrous oxide injection has become a very popular option for today's performance enthusiast for several reasons:

  1. Nitrous offers you more performance per dollar spent, than any other performance modification.
  2. Nitrous installations are relatively easy to accomplish.
  3. Since Nitrous is used only when needed, it offers you the advantages of complete driveability and normal gas mileage while not "on the button."
  4. Systems available for virtually any power need from 25 HP to over 500 extra HP.
  5. One of the few performance options available for today's computer controlled, fuel injected engines.
  6. Systems can easily be removed or transferred to another vehicle.

Why NOS?
