Frequently Asked
Questions -
Q. How does nitrous oxide create
more horsepower?
A. Nitrous oxide provides the
oxygen that allows an engine to burn more fuel, more burned
fuel equals more power.
Q. What is the difference between
a wet and a dry system?
A. A "Wet" system introduces a
homogenous mixture of nitrous and atomized fuel into the
incoming air stream, thus providing a perfect air/fuel
ratio for each.
Q. Can I still run my car all-motor
with nitrous installed?
A. Of course, the nitrous system
only affects performance when it is being used.
Q. How can nitrous blow my engine
up?
A. Nitrous in and of itself
cannot "blowup" an engine. Nitrous kits of poor design,
poor quality, and improper air/fuel ratios damage engines.
Q. What is nitrous backfire?
A. Nitrous backfires can be
caused by two situations. 1. A nitrous system that is two
rich or a system that atomizes the fuel poorly, thus causing
pooling or puddling of fuel in the intake manifold. 2.
A system that is operated too lean.
Q. What is meant by 30, 50, 100,
150, and 200 shots?
A. "Shot" is commonly used slang
in the nitrous community to refer to the amount of horsepower
increase provided by the nitrous system.
Q. How long can I squeeze nitrous
in my engine?
A. With an NX system the only
limitation is the capacity of the N2O bottle or the RPM
limit of the engine.
Q. When is the best time to use
nitrous?
A. When you want to go fast.
Q. How can a nitrous system be activated
(a "happy button," automatically, or what)?
A. All NX systems come standard
with wide-open throttle switches, however we offer an electronic
TPS switch as well as a push button.
Q. What is the safest way to configure
nitrous activation?
A. The only safe way is to use
a wide open throttle switch, however you may configure
any number of ways to "trip" the system but all must be
used in conjunction with some type of wide open throttle
switch.
Q. Is a bottle heater good?
A. A quality bottle heater is
essential to proper nitrous system performance.
Q. Can I vary the amount of nitrous
injected when I want?
A. Yes, by utilizing NX's digital
progressive controller, the "Maximizer". This devise allows
the user to precisely control the amount of nitrous delivered
to his engine from the comfort of the drivers seat.
Q. Can I install a nitrous system
on my car if there is no kit available?
A. NX has a system for every
car manufactured in the world today.
Q. How much of a horsepower increase
can I expect from a nitrous system?
A. All NX systems make within
2% of their claimed horsepower, if you jet the system for
50 horsepower then you can expect no less than 49 horsepower,
but usually a few more than the rated amount.
Q. How long will a bottle of nitrous
last?
A. That depends on the level
of power being produced. The formula for calculating your
nitrous usage is: 0.8 lbs N2O X 10 seconds = 100 horsepower.
I.E. If your system is jetted for 100 horsepower it will
use 0.8 lbs of nitrous for every 10 seconds of usage.
Q. How much does it cost to get
nitrous refills?
A. The cost of nitrous oxide
varies with the region of the country, however a general
estimate would be between $3.50-5.00 per pound.
Q. Are there nitrous systems available
for late model imports?
A. NX makes a system for every
car manufactured today.

with a 10 lb nitrous bottle, stainless steel bottle brackets,
16 ft aircraft style supply line, N2O filter, lifetime
warranty nitrous and fuel solenoids with mounts, all standard
jet settings, an NX patented Shark nozzle (nozzles), or
a patented carbureted plate, wide open throttle switch,
a complete installation pack that includes all bolts, nuts,
washers, wire, wire terminals, lighted arming switch, and
complete instructions with pictures.
Q. Will I need anything else to
install the kit properly?
A. To complete the installation
a Gen-X package should be ordered with the system. This
includes the bottle heater, liquid filled nitrous pressure
gauge, low fuel pressure safety switch, and a external
bottle vent fitting and plumbing kit.
Q. Can I hide my nitrous system
from a novice tuner?
A. Yes, it is quite easy to
hide an NX system from the casual observer.
Q. Can I use nitrous on my turbo
or supercharged vehicle?
A. Yes, NX specializes in turbo-supercharged
nitrous applications.
Q. What are some general rules for
creating the most horsepower without damaging anything?
A. Generally speaking the amount
of power that can be created with nitrous is almost limitless.
To avoid a catastrophe, the internal components of the
engine must match the amount of power that is going to
be generated. The use of proper air/fuel ratios is essential
and the quality of the nitrous system is paramount.
Q. Is a nitrous system worth the
money (horsepower per dollar wise)?
A. No other devise in the world
offers such a bargain as nitrous oxide.
Q. Why doesn't everyone use nitrous?
A. Nitrous is not for everyone,
some people prefer turbos, some like blowers, and others
feel it is cheating to use nitrous.
Q. Why does nitrous have such a
scary reputation?
A. There has been some very
shoddy nitrous "kits" sold to unsuspecting customers over
the last 20 years; this along with the abuse nitrous has
suffered from "idiots" who damage their own engines.

Technical Questions -
Q. How does a nitrous system operate
on a fuel-injected vehicle?
A. The NX system is a complete
stand-alone air/fuel delivery system that augments the
standard factory EFI unit. It provides additional fuel
and oxygen to the cylinders via the patented "Shark" nozzle
mounted in the intake tract to provide additional horsepower.
Q. How does a nitrous system operate
on a carbureted vehicle?
A. The most common method of
boosting power on carbureted applications is the use of
a "plate" sandwiched between the carb and the intake manifold.
This plate contains orificed tubes that deliver the nitrous/fuel
mixture in precise ratios.
Q. How easy is it to install a basic
wet nitrous system?
A. The NX "Stage One" EFI System
is very straightforward. It requires no engine disassembly,
no fuel system modifications or timing retards. Simply
install the "Shark" nozzle in the intake tract approximately
2-6 inches in front of the throttle body and connect the
fuel solenoid to the high-pressure side of the injection
rail and your ready to go.
Q. Purge valves look cool, should
I get one for my nitrous vehicle?
A. A purge valve is a valuable
tool for increased nitrous performance. It allows the user
to "Purge" all gaseous nitrous from the bottle supply line
prior to using the system. This allows for a harder "Hit" from
the system thus increasing performance.
Q. What safety features come with
a nitrous system?
A. There are several safety
related devises that can be used with a modern nitrous
system. The first, and most important is the wide-open
throttle switch. This prevents the user from accidentally
engaging the system. A special high flow nitrous filter
is furnished with every NX street system. All hoses are
aircraft quality stainless steel braided, Teflon. All NX
systems come with the highest quality, made in the USA,
stainless steel solenoids.
Q. How does the solenoid know when
to open and release the nitrous oxide?
A. All NX systems are furnished
with Wide Open Throttle switches. This switch signals the
solenoids to open when the motor reaches wide-open throttle.
Q. What are the differences between
a dry nozzle and a wet nozzle?
A. The "dry" system uses the factory
fuel injection to enrich the nitrous introduced into the
engine. The flaw with this technology is that no matter
how much nitrous arrives at a certain intake port it always
gets the same preset amount of fuel, or if a fuel injector
becomes clogged engine damage will result. The "Wet" technology
introduces a precise amount of fuel and nitrous through
a high tech mixing nozzle that atomizes the fuel to microscopic
proportions. This allows every cylinder to receive a precise,
homogenous mixture of fuel and nitrous, thus insuring a
safe, powerful increase.
Q. What is nitrous backfire?
A. Nitrous backfires can be
caused by two situations.
1. A nitrous system that is two rich or a system that atomizes
the fuel poorly, thus causing pooling or puddling of fuel
in the intake manifold.
2. A system that is operated too lean.
Q. Should I use an aftermarket ignition
with nitrous?
A. All NX Street or Stage One
systems are designed to operate with stock ignition; however
any upgrade in the stock ignition is a definite plus.
Q. Should I change my ignition system
in any way (timing, plugs, etc.)?
A. All NX Stage One or Street
systems are designed to operate with no timing retard.
Spark plugs should be changed to non-platinum style, 1
to 2 steps colder than stock.
Q. Will a bigger bottle give you
more horsepower?
A. No; however a larger capacity
bottle will provide a more stable bottle pressure resulting
in a lower E.T. and a higher M.P.H.
Q. What is the difference between
a 1 stage and a 2 stage system?
A. A single stage system refers
to one single nitrous system; a 2 stage or dual stage incorporates
two nitrous systems on one application. This allows a car
to launch with the maximum horsepower possible, with the
traction available, then add more power down track as the
car can handle it.
Q. Why does my engine need more
fuel while on the bottle?
A. The fuel, or gasoline, is
the source of the additional horsepower. The nitrous' job
is to provide the oxygen to allow the fuel to be burned.
Q. How can my engine get more fuel
while on the bottle?
A. All NX systems add additional
fuel during nitrous usage by injecting it directly with
the nitrous through their patented "Shark" nozzle. This
method assures 100% atomization of the fuel and accurate
air/fuel ratios.
Q. What is the safest way to configure
nitrous activation?
A. The only safe way is to use
a wide open throttle switch, however you may configure
any number of ways to "trip" the system but all must be
used in conjunction with some type of wide open throttle
switch.
Q. Is a bottle heater good?
A. A quality bottle heater is
essential to proper nitrous system performance.
Q. How much pressure should be in
my bottle?
A. All NX systems are designed
to operate between 900-1050 PSI.
Q. What accessories are available
for a nitrous system?
A. NX has over one hundred accessory
part numbers, ranging from digital progressive controllers
to space age bottle insulating jackets.
Q. Can I vary the amount of nitrous
injected when I want?
A. Yes, by utilizing NX's digital
progressive controller, the "Maximizer". This devise allows
the user to precisely control the amount of nitrous delivered
to his engine from the comfort of the drivers seat.
Q. Can I install a nitrous system
on my car if there is no kit available?
A. NX has a system for every
car manufactured in the world today.
Q. Do you have an installation manual
online so I can see if I want to install a kit on my car?
A. Yes.
Q. How does a nitrous system know
when I'm at wide-open throttle?
A. All NX systems are equipped
with wide-open throttle micro switches, or an optional
electronic TPS switch is available.
Q. How much of a horsepower increase
can I expect from a nitrous system?
A. All NX systems make within
2% of their claimed horsepower, if you jet the system for
50 horsepower then you can expect no less than 49 horsepower,
but usually a few more than the rated amount.
Q. Are there any dangers or things
to stay away from while using nitrous?
A. Of course, NX recommends
that no more than an additional 20 horsepower per cylinder
be used on a stock engine, with a stock fuel pump. Always
be sure you are using clean, uncontaminated nitrous. Also,
be sure you have the highest octane fuel available, I.E.
93 octane premium for, stock compression, street cars and
the highest motor octane fuel available for competition
type vehicles.
Q. Is there a trade off for engine
reliability and power produced with nitrous?
A. When used according to factory
recommendations, shortened engine life should not be a
concern.
Q. How long will a bottle of nitrous
last?
A. That depends on the level
of power being produced. The formula for calculating your
nitrous usage is: .8 lbs N2O X 10 seconds = 100 horsepower.
I.E. If your system is jetted for 100 horsepower it will
use .8 lbs of nitrous for every 10 seconds of usage.
Q. Can you feed an engine too much
nitrous even if you keep the air/fuel ratio the same?
A. Yes, if the mechanical limits
of the engine are exceeded catastrophic engine failure
will result.
Q. Are there nitrous systems available
for late model imports?
A. NX makes a system for every
car manufactured today.
Q. What comes with a nitrous kit?
A. Most NX systems come complete
with a 10 lb nitrous bottle, stainless steel bottle brackets,
16 ft aircraft style supply line, N2O filter, lifetime
warranty nitrous and fuel solenoids with mounts, all standard
jet settings, an NX patented Shark nozzle (nozzles), or
a patented carbureted plate, wide open throttle switch,
a complete installation pack that includes all bolts, nuts,
washers, wire, wire terminals, lighted arming switch, and
complete instructions with pictures.
Q. Will I need anything else to
install the kit properly?
A. To complete the installation
a Gen-X package should be ordered with the system. This
includes the bottle heater, liquid filled nitrous pressure
gauge, low fuel pressure safety switch, and a external
bottle vent fitting and plumbing kit.
Q. Can I hide my nitrous system
from a novice tuner?
A. Yes, it is quite easy to
hide an NX system from the casual observer.
Q. Can I use a nitrous kit on an
automatic?
A. Yes, the preferred application,
for nitrous, is an automatic transmission equipped vehicle.
Q. Can you powerbrake an automatic
with nitrous without it blowing up?
A. The answer is a qualified,
yes. If your brakes can hold your engine, at full throttle,
with the nitrous on, the answer is yes, but it is doubtful
this would be possible.
Q. Can a nitrous system be set up
to shut down once the brake is depressed?
A. Yes, if the user wires his
system with a double throw-double pole relay placed between
the arming switch and the wide open throttle switch that
is activated when the brakes are applied.
Q. Can nitrous systems be used with
aftermarket chips or ECU's?
A. Yes, however close attention
must be paid to excessive timing advance that could cause
detonation.
Q. Are drag racing launch techniques
any different with nitrous for AT or MT's?
A. Depending on the traction
available the launch techniques are the same, however with
the increased torque and horsepower generated by nitrous
usage, sometimes is necessary to delay the nitrous onset
for a brief period.
Q. How high must the RPM's before
activating nitrous?
A. The RPM level is not as important
as is the motors ability to rev freely when the nitrous
is engaged, I.E. If the vehicle is in low gear, nitrous
can be engaged at any time, but if the vehicle is in a
higher gear moving at a slow speed when the nitrous is
engaged the engine will detonate and damage will occur.
Q. Does nitrous increase cylinder
temperatures and combustion chamber pressure?
A. No, cylinder temperatures
should stay the same when the correct nitrous air/fuel
ratio is used. Yes, increased cylinder pressure equals
increased horsepower.
Q. Can I use nitrous on my high
compression engine?
A. Yes, but the proper octane
fuel must be used to prevent detonation.
Q. Can I use nitrous on my turbo
or supercharged vehicle?
A. Yes, NX specializes in turbo-supercharged
nitrous applications.
Q. What are some general rules for
creating the most horsepower without damaging anything?
A. Generally speaking the amount
of power that can be created with nitrous is almost limitless.
To avoid a catastrophe, the internal components of the
engine must match the amount of power that is going to
be generated. The use of proper air/fuel ratios is essential
and the quality of the nitrous system is paramount.
Q. What pressure should my nitrous
bottle be at?
A. All NX systems are calibrated
to operate at 900-1050 PSI.
Q. What if the pressure is too high,
should I cool it?
A. If the bottle pressure is
in excess of 1100 PSI the bottle should be cooled using
a wet towel or chamois.
Q. Is there any harm that can be
done to my engine if I use nitrous while the bottle pressure
is too high?
A. Yes, the nitrous system will
run "lean" if the nitrous pressure is high beyond specification.
This could cause severe engine damage.
Q. Where should I run the main nitrous
feed line?
A. The feed line can be run
either under the car of through the passenger compartment.
Care should be taken to route the line away from any voltage
points or moving suspension parts.
Q. Where should I install my bottle?
A. The ideal place to mount
the bottle is in the trunk; however if your car is a hatchback
it is permissible to mount it in the passenger compartment
if an external pressure relief vent is properly installed
on the bottle.
Q. What if my bottle leaks while
I'm driving, could I get busted for OWI?
A. To become, "intoxicated", the
nitrous leak would have to be severe and noticeable. No
excuses to be found here!
Q. Is a nitrous system worth the
money (horsepower per dollar wise)?
A. No other devise in the world
offers such a bargain as nitrous oxide.
Q. Why doesn't everyone use nitrous?
A. Nitrous is not for everyone,
