Nitrous Express EFI NITROUS PLATE SYSTEM FOR GT500 - Manual (Page 7)

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
cause detonation, burned plugs, poor performance, and engine damage. In competition engines
always use the coldest plug available. Never use an extended tip plug in a racing engine.
4. The NX nitrous system is so advanced, (technology, engineering, and workmanship) that huge amounts
of timing retard is not required. You may run as much timing as you normally would, if you have the
octane required to prevent detonation. We recommend 1 degree timing retard for each 50 horsepower
boost as a starting point. Your engine may need more or less depending on your combination.
5. Your fuel system is also an integral part of the nitrous system, be sure it is in top shape and all filters
are clean.
6. Engine operating temperature should be between 160 and 200 degrees prior to nitrous usage.
7. Never “lug” your engine and hit the nitrous system, use the system at wide-open throttle only, nitrous
should not be used below 3000 rpm’s. If you do any of the above a serious “Back Fire” could result in
engine damage.
8. The better the exhaust system the better the nitrous system will work.
9. Do not attempt to drill or alter the jets, solenoids, or the tubes in the nitrous plate. These items are
engineered to their maximum capability. Any modification you can make will decrease power and
destroy engine parts.
10. Do not mix or attempt to match any other brand solenoids with this system. Do not attempt to mix or
match any other brand plate or nozzle with this system. Do not attempt to use any other brand kit as a
