nos or nitrous

Nitrous is a cheap way to make a lot of power. Nitrous comes in kits and can increase your power anywhere from 50 hp to 400 hp. The nitrous is limited by the engine’s ability to handle the power. A 200 horsepower engine is not meant to handle 400 hp of nitrous. An engine built correctly can handle massive amounts of nitrous. On a standard engine the ignition will need to be retarded. The fuel will also have to be increased either by the fuel map or a fuel nozzle. Nitrous was first used in aircraft to help the plane gain alot of altitude very quickly. Soon after people realized the potential and set up systems on cars. Unfortunately at this time there were not many good ways to control fueling verses nos being sprayed. Many people blew up there engines because of having a lack of understanding of nitrous. Today kits have come a long ways and have the setup down to a science. Nitrous can be very reliable as long as it’s not used excessively per engine setup.

Nitrous systems now even have the capability of feedback, like a fuel injection setup. If the o2 sensor reads the engine is lean it will shut off the spray of nitrous to save the engine from damage. Also sensors restrict the spray from occuring until the engine is under full load or close to, for saftey. Other systems work in stages to control wheelspin. Nitrous does two things, first it is compressed in the bottle by the manufacturer. When nitrous is sprayed it decompresses significantly and cools down the incoming air. Secondly when the NOS enters the chamber the heat breaks down the molecule in an endothermic reaction into twice as many molecules of oxygen. As you know cool air and more oxygen = alot of power. Bottles will normally run a handful of times dependent on amount of use and duration of use. They can usually be filled locally at a gas supply company or race shop. The main use for nitrous is, and always has been drag racing. Kits are usually rated by horsepower and can be from 50 to 400 horsepower dependent on what your motor can handle.
