If the load increases exceed the ability of the components to handle them, added wear takes place. NOS kits are designed for use on demand and only at wide open throttle. Nitrous can be extremely advantageous in that it is only used when you want it, not all the time. All NOS kits are designed for maximum power with reliability for a given application. The NOS system is independent of your carburetor and injects its own mixture of fuel and nitrous. Nitrous Oxide by itself is non-flammable.
However, the oxygen present in nitrous oxide causes combustion of fuel to take place more rapidly. Not directly. Detonation is the result of too little fuel present during combustion lean or too low of an octane of fuel. Too much ignition advance also causes detonation. In general, most of our kits engineered for stock type engines will work well with premium type fuels and minimal decreases of ignition timing.
In racing application where higher compression ratios are used, resulting in higher cylinder pressures, a higher fuel octane must be used as well as more ignition retard. Simply call for the location of the nearest NOS dealer with refilling capabilities. Is it a good idea to use an aftermarket computer chip in conjunction with an NOS System? Only if the chip has been designed specifically for use with nitrous oxide.
Most aftermarket chips use more aggressive timing advance curves to create more power. This can lead to possible detonation. You may wish to check with the manufacturer of the chip before using it.
The top manufacturers, such as Hypertech do make special chips for use with nitrous. Which type of manifold is better suited for a plate injector type of nitrous system, single or dual plane manifold? The distribution is better with a single plane at high RPM. If your goal is to increase power by more than HP, the single plane manifold is better.
Are there benefits to using nitrous with turbo or super-charger applications? In turbo applications, turbo lag is completely eliminated with the addition of a nitrous system.
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.
Tap into your fuel feed line and install a "T" fitting for the fuel solenoid, this will provide the additional fuel you need for the nitrous. Using your new gaskets, install the nitrous plate into the intake manifold, then the carburetor. Make sure you reattach all of your hoses, clamps and other hardware.
Wire up the system with a 4 prong, 30 amp relay. The system will utilize an "arming" switch then a momentary switch to spray the nitrous. When both switches are pressed, it will send power to the solenoids, spraying nitrous and fuel. Install a pressure gauge, preferably at the nitrous solenoid so you know how much nitrous you have or don't have!
