Nos how does it work

In addition, both turbo and superchargers compress the incoming air, thus heating it. With the injection of nitrous, a tremendous intercooling effect reduces intake charge temperatures by 75 degrees or more. Boost is usually increased as well, adding to even more power. NOS prides itself on offering the most complete systems on the market today.

They include virtually every component that may be needed for a complete installation; parts such as extra long carburetor studs, gaskets, pipe tap, fuel hose, brackets, filters, fittings, hardware, wiring, 10 lb.

The orifice of the Hi-Flo valve is much larger than the standard valve allowing for a larger flow of nitrous. With a small orifice valve a pressure drop could occur when nitrous flow is high; causing surging or inadequate nitrous flow. What affect does nitrous have on an engine with considerable miles on it? This depends largely on the actual condition of the engine components. Any performance modification to an engine that is worn out or poorly tuned will have detrimental effects.

However, an engine in good condition, with good ring and head gasket sealing, should be able to use nitrous without any abnormal wear. NOS bottles come with siphon tubes and, in order to maintain proper nitrous pickup, it is important to mount the bottle correctly. We recommend mounting the bottle at a 15 degree angle with the valve end higher than the bottom of the bottle. The valve end of the bottle should point to the front of the vehicle and the valve knob and label should face straight up.

Most late model ignition systems are well suited for nitrous applications. In some higher HP cases, it may be advisable to look into a high quality high output ignition system with a built in spark retard. Chilling the bottle lowers the pressure dramatically and will also lower the flow rate of the nitrous causing a fuel rich condition and reducing power.

On cold evenings you might run on the rich side. For optimal running conditions, keep bottle pressure at approximately psi. NOS has a nitrous pressure guage that allows you to monitor this. If you live or operate a nitrous system in colder temperatures, it may also be a good idea to purchase a bottle heater kit, part Generally, ambient temperatures of degrees Fahrenheit will allow for best power potential of NOS kits.

The increase in oxygen present in the exhaust may actually increase the efficiency of the converter. Since the use of nitrous is normally limited to seconds of continuous use, there usually are no appreciable effects.

Temperatures are typically well within acceptable standards. Some of the most important components of any nitrous system are nitrous and fuel filters.

To keep contaminants from attacking the solenoid or plugging up a jet, NOS nitrous filters feature a special stainless steel mesh element from the aerospace industry. Use of a premium type leaded or unleaded fuel of 92, or greater, octane is recommended for most applications. Many NOS systems are designed for use with service station pump gas. However, when higher compression or higher horsepower levels are used, a racing fuel of octane, or more, must be used.

Generally, cams that have less exhaust overlap and more exhaust duration. There are special cam grinds available for nitrous competition which have more aggressive exhaust profile ramping, etc. Since cam selection depends largely on vehicle weight, gearing, etc. What type of nitrous system is better; a plate injection system or a direct port injection system?

The advantages of a plate system are ease of installation and removal, ability to transfer easily to another vehicle, ability to change jetting combinations quickly, and in most cases, provide you with all the extra HP you will ever need 75 to more HP.

In some cases, such as in-line type engines with long runners, a direct port type system is advisable for maximizing distribution. Direct port injection is also desirable when the system is hidden under the manifold.

Most stock fuel pumps will work adequately for smaller nitrous applications. It is important to check to see if your pump can flow enough fuel to your existing fuel system whether carburetor or fuel injected , as well as being able to supply the additional fuel required by the nitrous kit under full throttle conditions.

It may be a good idea to dedicate a separate fuel pump to the nitrous kit. What are the advantages of using nitrous compared to other performance options? The cost of many other performance options can put you in the poorhouse.

Updated: Apr 19, When nitrous oxide is heated to degrees F, its molecules split into nitrogen and oxygen. This means more oxygen is produced for combustion, allowing the engine to produce more power in the process. Is NOS street legal? Nitrous oxide systems, also known as NOS, may be permitted for use depending on local city regulations.

NOS is legal to use in some classes of auto sports. Does nitrous damage your engine? Using high-quality nitrous that's been fitted correctly and according to the requirements of your car should be safe for the engine and will not cause the engine to overheat or explode. How do you apply nitrous to a car? You will first need to find the safest place to mount the nitrous bottle. You will then have to install a nitrous line by removing the carburetor and setting up the nitrous plate. This is document ajlq in the Knowledge Base.
