Performance Notes |
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:
Why NOS? Through years of involvement with all forms of high performance racing, NOS has evolved into the world's largest manufacturer of performance nitrous systems. NOS designs and engineers nitrous systems for virtually anything with an internal combustion engine from stock to highly modified cars, motorcycles, watercraft, aircraft and even snowmobiles. NOS has become synonymous with quality high performance automotive products. Research and development, engineering and technical support assure you of being part of the winning NOS team. |
