NOS
Term used for nitrous oxide. Somewhat incorrect since NOS is a company that produces nitrous oxide, also the company is pronounced as spelled...N, O, S; opposed to the common pronounciation similar to the word "gnaw" except with an "s" sound at the end. This term was put into play mainly by the movie series of "The Fast and The Furious". Most people that say the "gnaws" pronounciation of this have no clue what they are talking about with cars and are what you would consider "wanna be's"
Im going to go say NOS (gnaws pronounciation) cause it was in a movie.

NOS
Noun.
1) An acronym for the brand name 'Nitrous Oxide Systems'. NOS produces a chemical known as nitrous oxide, often used in the performance optimization of car and motorcycle engines. The chemical (N2O) breaks up upon contact with air, releasing extra oxygen into the engine. This often means that oxygen detectors in modern cars pick up the extra oxygen and add more fuel to the a/f mixture. This means the engine will pack a harder punch than it typically would, in the form of an instant flywheel horsepower gain.
2) A buzzword used by the illegal street racing comunity (often populated by rice burners), to make one's car sound fast. Many misconceptions have arisen from the term NOS, particularily founded by the film iThe Fast And The Furious/i. One misconception is that NOS can be installed on any car, and with the push of a button it will result in an exponential gain in speed. Another is that NOS iis/i nitrous oxide; NOS is only a brand name. Nitrous oxide can only be installed on some engines, and does not necessarily mean a huge gain in speed. It is NOT activated with the push of a button, most nitrous systems have a throttle trip system that activates the nitrous flow at WOT (wide-open-throttle), in order to maximize potential speed. Another widely mentioned misconception is that nitrous oxide is flammable. It is not. Though any compressed gas can explode when heated, the gas itself is non-flammable.
