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 second stage with this system. Our nitrous technology is far superior to any
of our competitors. Any attempt at this could lead to serious engine damage.
11. All of our systems are designed to operate at 1050 PSI bottle pressure. This is extremely important and cannot be stressed enough. If your
bottle pressure is below 1050 PSI the system will run rich and will not produce the advertised horsepower. If the bottle pressure is above
1050 PSI the system will run lean, possibly damaging engine parts. This pressure is easily monitored by using a NX liquid filled pressure
gauge (PN 15509). Note: When the ambient temperature is below 97 degrees a bottle warmer is required (PN 15940 or 15941). An NX
bottle jacket (PN15945 or 15946) will help stabilize bottle pressure in the winter and summer.
CAUTION: NEVER USE AN OPEN FLAME TO HEAT A NITROUS BOTTLE. THIS IS A VERY DANGEROUS AND
POTENTIALLY FATAL PRACTICE!!!!!!!!!!!
12. A purge valve (PN15600-15601) is recommended on all NX systems. When the weather begins to get hot a purge valve is worth up to a tenth
of a second on a 1⁄4 mile pass. Note: The correct purging procedure for drag racing is: 1. Complete the burnout. 2. Light the pre-stage bulb.
3. Push the purge button three times, one second each. 4. Stage immediately, GO FAST.
13. If there is a question about the purity of your nitrous supply, a filter (PN15610 or 15607) should be used when refilling your bottle. Just attach
the filter to your bottle when you take it to be refilled. Contaminated nitrous will cause serious damage to the nitrous solenoids and possibly
to your engine. This is a lifetime renewable filter.
14. If you have questions about the suitability of your torque converter or gear ratios, call the factory tech line for the inside scoop.
15. Your nitrous bottle should be turned off when not in use (even between runs). An NX remote bottle opener (PN 11107) will make this task
much easier.
16. Start with the lowest power setting in your system. Don’t try to be the track “Hero” on your first pass. Remember start out small and work
your way up, NX systems produce more real horsepower than any other brand on the market today.
17. If the solenoids must be disassembled for cleaning or rebuilding always use the proper wrench (PN 15921). Do not use any clamping devise
on the solenoid tower, instant non-warranty, damage will result.
18. If you run an NX system of 150+ horsepower you must use a high octane racing type fuel. These are some tips to help you choose and
maintain the correct fuel for your application:
A. The most important statistic you should look for in the fuel specifications is the “MON” or motor octane number. In most cases the
higher the number the more timing you can run and detonation will not be a problem
B. Most V-8 or V-12 engines with stock compression will run on “93” unleaded pump gas with up to 150 horsepower boost, most 4 or 6
cylinders with stock compression can use up to 75 horsepower.
C. Racing engines with 10-1 compression or higher must run racing fuel. The higher the compression, and the higher the boost, the higher
the “MON” must be.
D. With nitrous usage usually the highest “MON” available is the one that should be used.
E. All NX systems are calibrated to use fuel with .730 specific gravity or “SG”. If you use a fuel with a lower “SG” you must use a larger
fuel jet to compensate for the lighter fuel. If you use a fuel with a higher “SG”, a smaller fuel jet will be required. Most unleaded
pump gas is .730 SG or above.
