NOS nitrous oxide is legal for use in most states when used in accordance with state and local traffic laws. NOS does not recommend or condone the use of its products in illegal racing activities. NOS has not pursued California Air Research Board (CARB) exemptions for these kits, hence, they are not legal for use on pollution-controlled vehicles in California. A correctly installed NOS nitrous system should not alter the emission control performance of your vehicle under standard EPA tes

WHAT IS NITROUS OXIDE? NITROUS OXIDE… …Is a cryogenic gas composed of nitrogen and oxygen molecules …Is 36% oxygen by weight …Is non-flammable by itself …Is stored as a compressed liquid …Exists in two grades—U.S.P. and Nitrous Plus: U.S.P. is medical grade nitrous oxide; its common use is dental and veterinary anesthesia. It is also commonly used as a propellant in canned whipped cream. U.S.P. is not available to the public. Nitrous Plus differs from U.S.P. in that it contains tr

These kits have been designed for safety and smoothness of operation. Nitrous oxide is injected into the engine only when the following conditions are met: Bottle valve is opened. System is armed. Engine is at wide-open throttle. RPM conditions are met. Horsepower and torque increases due to these kits will vary with engine displacement and modifications. Approximate power increase estimates can be made based upon the massflow of nitrous oxide into the engine. The following tab

2. Install the Soft Plume Nozzle (22), taking into account the length of the nitrous and fuel supply hoses and the intended location of the solenoids. Take into account that the nozzle mounting bung (21) needs to be restrained during final installation, and accessibility of a tool is important. Make sure the nozzle and feed lines will not interfere with engine components or accessories and will not interfere with the hood when closed. The nozzle should not move from the perpendicular posi

2.10 WOT/Window Switch Troubleshooting- Verifying the operation of the NOS WOT/Window Switch NOTE: NOS highly recommends that the user NOT change the factory WOT/Window Switch settings. The WOT/Window Switch should be set at the - 3000 rpm (low) and 6000 rpm (high) - default settings. With the NOS WOT/Window Switch, these values are adjustable, but altering them is not recommended. The NOS WOT/Window Switch also has a TPS/Microswitch built into the unit. The default and recommended s

Chapter 3 Routine Maintenance 3.1 Nitrous Solenoid Filter When nitrous bottles are refilled they can become contaminated with debris, if the refiller does not have an adequate filter in their transfer pump mechanism. Contaminants in the bottle will eventually become lodged in the nitrous solenoid filter fitting. You should periodically (after every 20-30 pounds of nitrous usage) examine the mesh in the nitrous filter for debris. To clean the filter, follow the following steps:

Nitrous Oxide Accessories NOS systems are calibrated for optimum performance with a bottle pressure of 900-950 psi. The pressure will change with temperature. Heater kits are thermostatically controlled to keep the bottle near 85° F to provide correct pressure. Bottle Heater (P/N 14164NOS) is available for 10 & 15 lb. bottles. Insulating the bottle helps maintain pressure by keeping heat in the bottle when it’s cold, or heat out when it’s hot outside. The blankets are made of a ru
