     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
        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 sulpher dioxide added to prevent
        substance abuse.  Nitrous Plus is intended for automotive applications and is available for sale to the

     In automotive applications, Nitrous Plus and fuel are injected into the engine’s intake manifold, which
     produces 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).
     !  Increase the rate at which combustion occurs in the engine’s cylinders.

     Do’s and Don’ts of Nitrous Oxide


     !  Read all instructions before attempting to install your DynoTune 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 Teflon-based paste on pipe-style fittings.
     !  Make sure your engine and related components (ignition, carburetor, and driveline) are in proper working
        condition. Do not use any performance chip or modified computer that advances timing more than stock.
     !  If nitrous is accidentally injected into the engine when it is not running, remove the engine coil wire, open
        the throttle, and crank the engine 10 to 15 seconds before starting.  Failure to do so can result in an
        explosive engine failure.
     !  Use your DynoTune 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.


     !  Engage your nitrous system with the engine off.  Severe engine damage can occur.
     !  Modify DynoTune nitrous systems (if you need a non-stock item, call DynoTune Technical Service for
     !  Over tighten AN type fittings.
     !  Use Teflon Tape on any pipe threads.  Pieces of Teflon tape can break loose and become lodged in
        nitrous or fuel solenoids or solenoid filters.  Debris lodged in a nitrous or fuel solenoid can cause
        catastrophic engine failure.
