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 trace amounts of Sulphur Dioxide added to prevent substance abuse. Nitrous
Plus is intended for automotive applications and is available for sale to the public.
In automotive applications, Nitrous Plus and fuel are injected into the engine’s intake manifold, producing the following results:
Lowers engine intake air temperature, producing a dense inlet charge.
Increases the oxygen content of the inlet charge (air is only 22 percent oxygen by weight).
Increases the rate at which combustion occurs
in the engine’s cylinders.
DO’S AND DON’TS OF NITROUS OXIDE
Do’s
Read all instructions before attempting to install your SNIPER nitrous system.
Make sure your fuel delivery system is adequate for the nitrous jetting you have chosen. Inadequate fuel pressure or flow will
result in engine damage.
Use 14 gauge (minimum) wire when installing electrical system components.
Use high-quality connections at all electrical joints.
Use PTFE-based paste on pipe-style fittings.
Make sure your engine and related components (ignition, carburetor, and driveline) are in proper working condition.
Do not attempt to start the engine if the nitrous has been injected while the engine was not running. Disable the ignition
and fuel systems (consult owner’s manual) and turn the engine over with the throttle wide open for several revolutions
before attempting to start. Failure to do so can result in extreme engine damage.
Use your SNIPER nitrous system only at wide-open throttle and at engine speeds above 3000 RPM.
Install a proper engine to chassis ground. Failure to do so may result in an explosive failure of the main nitrous supply
line.
Use a high-quality fuel, as suggested in Chapter 3, Baseline Tuning Suggestions.
Don’ts
Engage your nitrous system with the engine off. Severe engine damage can occur.
Modify SNIPER nitrous systems (if you need a non-stock item, call SNIPER Technical Service for assistance)
Overtighten AN type fittings.
Use PTFE Tape on any pipe threads. Pieces of PTFE tape can break loose and become lodged in the nitrous or fuel solenoids or
solenoid filters. Debris lodged in a nitrous or fuel solenoid can cause catastrophic engine failure.
Use sealant of any kind on AN type fittings.
Allow nitrous pressure to exceed 1100 psi. Excessive pressure can cause swelling or in extreme cases failure of the nitrous
solenoid plunger. Solenoid plungers are designed so that pressure-induced failures will prevent the valve from operating. No
leakage should occur with this type of failure.
Inhale nitrous oxide. Death due to suffocation can occur.
Allow nitrous oxide to come in contact with skin. Severe frostbite can occur.
Use octane boosters that contain methanol. Fuel solenoid failure may occur, producing severe engine damage.
Chapter 1 Introduction to Your SNIPER Nitrous Oxide Kit
1.1 General Information
Kit Number 07166NOS was engineered to be a clean, simple installation on the Ford 5.0L Coyote V8 engine. Power output can be
increased from 75 to 150 Rear Wheel Horse Power (RWHP) with the supplied jetting. The system can support up to 250 RWHP with
optional jetting, and upgraded solenoids, but be aware that an increase over 150 RWHP will require an upgrade to the OEM fuel system
in the form of an increased capacity fuel pump or a dedicated, stand-alone, fuel system.
Although this system was engineered for the 2011-16 Mustang, it can easily be installed on any Ford Coyote engine that utilizes an
80mm, 4 bolt cable operated throttle body. The wiring and electrical connections will need to be adapted to the different control system
used.
