NOS

A brand name, and probably the most popular of them, for nitrous oxide. The name stands for Nitrous Oxide Systems, and well, it is just that. Referred to as "spraying", or "bottle", or "Cheating", it is a very simple way to enhance power of the internal combustion engine. The nitrous oxide (N20) is kept in a bottle and is directed to the intake through your fuel injection or carbueration(more time consuming to install). Thoug it is called nitrous, that is not what enhances performance. When nitrous oxide is heated to about 570 degrees F. (the combustion chamber temperature.), it splits into 2 parts nitrogen and a part oxygen. Everyone knows that an engine likes to breathe, and by the N20 splitting, the added oxygen allows it to do just that. By allowing more oxygen, you also allow more fuel, all this explains the horsepower boost of maybe 10-30% depending on the amount used. As for the nitrogen, well, it makes the exhaust look cool, especially on straight pipes!

realMAN-that cheater is using Nitrous.
Nitrousman-yeah, it helps the engine breathe.
realMAN- Whatever, your head gasket is gonna be leaking more oil than president Bush can deny.
Nitrousman-its a v-tech, it can handle it.
RealMan-you want air? check this out, I got a carb for each cylinder, and i got twice as many cylinders as you, Fag!

Nos

1. Nitrous oxide (or NOS), a bottle of N2o that people are to sorry to admit are only used to be put on badass cars to make them go a extra 30 to 50mph when the idiots crash into a wall and has to look good, but hay, I use it for my Supra (which is not a fart rice because it is actually as fast as it looks, ricers have them look fast, but they really go slower then the stock version because they tried to tune it from their "inner street racing knowledge").

2. a bottle that 34% of the time is used to be put on fart rice (big difference between ricer car and import car). And when it is equipped, the ricer realizes it's empty because he bought it from the corner store as a drinkable liquid thats called NOS.

Ricer guy: Yeah I need some Nos

corner store guy: Oh, you want NOS Ehh, I got it right here

Ricer guy: Oh, well here's a dollar

corner store guy: No, this cost 5 dolla for 2 liter

Ricer guy: Damnit, I'll just take a small shot

corner store guy: Okay, that 3 dolla and 50 cent

Ricer guy: What!

Corner store guy: Oh sorry, you said SHOT of NOS, here you go 2 dolla

Ricer guy: That couldnt even speed up my hot wheels car!!

Corner store guy: Just getta fuck outta my store!!
