Nitrous Express 3-BOLT LS NITROUS PLATE SYSTEM - Manual (Page 7)

All NX systems are designed for off road usage. Use extreme caution and observe all safety
precautions (see your vehicles owner’s manual). Select a suitable test area; your local racetrack is best.
Arm the system with the cockpit N2O arming switch. Gently launch the vehicle, gradually accelerating to
wide-open throttle. When WOT is achieved a noticeable surge of power should be produced. If not stop
and recheck all installation procedures. Call the factory tech line if the problem cannot be located. NOTE:
All vehicles equipped with factory rev-limiters should take extreme care not to over-rev the engine. If the
rev-limiter is engaged with the N2O system on, serious engine damage could result. An aftermarket RPM
window switch (NX PN# 18959) should be used to disengage the N2O system 200 RPM’s before the rev-
limiter activates. Your NX system is now ready for regular usage.
SAFETY TIPS:
Do not attempt to start engine if nitrous has been accidentally injected while the engine was not
running. Disconnect coil wire(s) and turn motor with throttle wide open for several revolutions before
attempting to restart. If it is not possible to disable the ignition then the spark plugs must be removed and
the engine cleared of all nitrous before attempting to start engine.
1. Never permit oil, grease, or any other readily combustible substances to come into contact with nitrous
cylinders, valves, solenoids, hoses and fittings. Oil and certain gases (such as oxygen or nitrous
oxide) may combine to produce a flammable condition.
2. Never interchange solenoids or other appliances used for one compressed gas with those used for
another.
3. Identify the gas content by the label on the bottle before using. If the bottle is not identified to show the
gas contained, return the bottle to the supplier.
4. Do not deface or remove any markings, which are used for content identification.
5. Cylinder valves should be closed except when nitrous is actually being used.
6. Notify supplier of any condition, which might have permitted any foreign matter to enter the valve or
bottle.
7. Never drop or violently strike the bottle
8. Keep valves closed on all empty bottles to prevent accidental contamination. Open the bottle valve for
an instant to clear opening of any possible dust or dirt before usage. Aim bottle outlet away from all
body parts. Do not point it in the direction of a person.
POWER TUNING TIPS:
Nitrous oxide works well with all applications; 4 cycle, 2 cycle, diesel, and rotary engines. Each one has
individual tuning characteristics, and these tips apply generally to each one. Nitrous oxide is referred to as
“Liquid Supercharging” because it, in effect, does the same thing as a mechanical supercharger, forcing
more fuel and oxygen into each cylinder, thus producing more power. The biggest enemy of all
supercharged, turbo charged and nitrous injected engines is “DETONATION”. The use of higher-octane
fuel, and or a combination of better fuel and timing retard can control this. Remember detonation is a
spark plug, head gasket and engine “KILLER”.
1. Your engine should be tuned to its maximum power prior to nitrous usage.
2. The ignition is an integral part of the nitrous system and must be able to ignite the mixture under very
high cylinder pressures. The hotter the spark the better!
3. In stock engine applications and street usage the spark plugs should be at least 2 steps colder than
stock. Do not use platinum tip, extended tip or any plug with multiple ground straps or split ground
straps. When in doubt about heat range always go one step colder. A spark plug that is to “Hot” will
