Methods and guidelines for installing NOS (nitrous oxide system)

Nos is a nitrous substance that has more oxygen than normal air

the following is how to activate nos:

  • press the nos button on the car
  • Nitrous gas from the bottle mixed with gasoline
  • enter the combustion chamber through the intake
  • can then cause a powerful explosion

Usually can increase engine speed by 50 ++. Nitrous is very dangerous if you use it often because it can cause engine damage if the part in the engine is not strong. Nitrous has the name bekan n2o, which is often called nos (nitrous oxide system). all brands of nitrous work always the same. many or often used in racing, especially drag races. nitrous in the form of liquid in this pressurized tube easily evaporates by pressure from the atmosphere. this compound that enters the combustion chamber then split into 2 elements, namely oxygen and nitrogen. oxygen levels in nitrous oxyde compounds, it is the mixing of oxygen with hydrocarbons that makes a big boost to the engine. the role of this nitrous is cooling, compression, and instant power output which provides instant power compression so that the engine gets a great boost while nitrous is in the chamber the use of a purg valve which is often said to be cool also has a function as a wind exhaust on nitrous, so that nitrous is directly on the selenoid

The types of nozzle installation include:

Wet System

Installation between the manifold and throttle body. or single nozzle in the intake channel. This installation mixes nitrous and fuel in the nozzle so that it is called the wet system. This installation is relatively simple and the settings are easier.


Dry System

This installation requires an extra injector for fuel. installation of the nozzle in the intake channel. Nitrous will mix with gasoline in this extra injector, then mix again with the fuel injector, then enter the chamber. installation and settings are more complicated because the air-fuel ratio setting is more difficult. the way can be by outsmarting the sensor maf. This nozzle is usually set at an angle of 90 degrees.


Direct Port system

The most complicated installation. this requires drilling in the manifold. installation directly to the engine intake port. the principle is similar to the wet system. only the nozzle mixed with nitrous + fuel is channeled independently to each cylinder. there is another type of direct system which is multi-point. this produces the most power. Nitrous is supplied through 1 nozzle for 1 cylinder. this also allows for larger placement of selenoids.

The entry of this nitrous through selenoid and fogger, also has various types. usage of nitrous is identical to instant speed and instant power. many changes have occurred in the machine for this usage. one thing to note, this additional power is identical to the heat of the engine, also identical to the increase in compression. this increase in compression can result in a short-lived engine. For a natural aspirated car, where the engine compression is high, it is advisable not to install nitrous, because it is very fatal for the engine. only low settings are recommended for long-term machine durability.

For forced-induction cars, both turbo and supercharged, nitrous installation must also be considered carefully as a natural aspirated engine. even though the forced-induction engine has low compression, when the boost enters, compression increases dramatically. this results in a large power surge. When high compression by boost, use of nitrous can be fatal if not accompanied by the right timing setting. a high boost by a turbo / supercharger, plus nitrous can result in damaged engine components, such as heads, valves. piston, conrod even to the crankcase if excessive. there are also those who crack the block because the engine cannot withstand the compression surge and the heat generated by nitrous.
