I hope you all can use this as a guide to help you with your nitrous questions, and help you make the decision on whether nitrous is the path to go for you or not-

The basic facts of nitrous oxide are these:
- Nitrous oxide is a cryogenic gas composed of nitrogen and oxygen molecules. (N2O)
- Nitrous is 36% oxygen by weight.
- Nitrous is NON-FLAMABLE by itself.
- Nitrous is stored as a compressed liquid.
- Nitrous exists in two grades: USP (medical grade) and NitrousPlus (What is used in the cars/trucks).
(On Nitrous+, sulphur dioxide is added to prevent substance abuse. Sniff this stuff, and you'll look like Phyllis Diller on a bad hair day.)

Here are some benefits of nitrous oxide in automotive applications:
- Lowers intake temperature, producing a dense inlet charge.
- Increases the oxygen content of the inlet charge. (Air is "only" 22% oxygen by weight)
- Increases the rate at which combustion occurs in the engine's cylinders.

The dont's of nitrous


Don’t spray with out full throttle-you will get a nitrous build up in the motor

Don’t spray with the temp below 950 or over 1200- if it is under it will run rich (not real bad) if it is over will run lean (very bad)

Don’t spray if the motor is not running right-it don’t get better with the bottle

Don’t spray with out purging it first- wont always break something, but could

Don’t over rev the motor - most car/trucks have a factory rev limited that shuts off the fuel so you will only have nitrous ----boom

the first time you hook it up do a test with out the fogger in the motor to make sure you are getting fuel/nitrous on wet kits

Don’t spray with advance timing-boom

if you don’t think it sounds right (the motor) it probably don’t

Don’t spray if you dont think something is right (it probably aint)

You wont know more if you don’t ask

more nitrous is not always faster/better

know the limits of the motor as a rule of thumb you can run half of what the motor pushing out

QUESTION / ANSWER ABOUT NITROUS

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. 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 1” 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 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 airstream, thus providing a
perfect air/fuel ratio for each cylinder. A “Dry” system introduces
raw nitrous into the incoming airstream and depends on the EFI’s
injectors to provide the fuel enrichment. The problem with this
method is no intake manifold has perfect distribution and this
allows each cylinder to receive differing amounts of raw nitrous
but only provides a preset amount of fuel from each injector.
This results in rich-lean conditions throughout the engine
often causing engine damage.

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 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 is nitrous backfire?

A. Nitrous backfires can be caused by two situations.
1. A nitrous system that is too 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 1 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 1 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. 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% atomazation of the
fuel and accurate air/fuel ratios.

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

excellent information.

i agree patrick. i think we should sticky this

Done.

Also to add to this i recomend using a RPM activated window switch for extra protection. A window switch will active the nitrous within a certain RPM window that is completely adjustable. Combined with a wide open throttle switch it is one of the safest ways to run nitrous.
