WHAT IS NITROUS OXIDE?
Nitrous Oxide is a cryogenic gas composed of nitrogen and oxygen molecules. It is stored as a “gas
over a liquid” which means that both liquid and gaseous nitrous oxide is delivered into your engine. It is
36% oxygen by weight, which is what produces the added horsepower. By injecting more oxygen (and
a corresponding fuel signal), we create the additional power the same way a supercharger or a
turbocharger does.
Nitrous Oxide is considered an “oxidizer” and not a fuel. Therefore, nitrous oxide is non-flammable by
itself. Because nitrous oxide is a cryogenic, the same safety methods in handling dry ice apply to
nitrous. Direct contact with the skin will cause a burn similar to contact with dry ice. The exception in
using nitrous oxide comes from increased breathing hazards associated with the gaseous properties of
nitrous oxide.
Nitrous Oxide is offered for sale in two common grades, which are U.S.P., and
Nytrous Plus
U.S.P.
nitrous oxide is medical grade nitrous oxide. Its common use is dental and veterinary anesthesia as well
as use as a propellant in food such as canned whip cream. U.S.P. is not available to the public and
would provide no advantage in the making of horsepower over the automotive grade nitrous oxide.
Nytrous Plus
was specifically designed for automotive consumption and differs from U.S.P. in that it
contains trace amounts of sulfur dioxide (100 parts per million or “PPM”) added to prevent substance
abuse. The Sulfur Dioxide is an irritant to all of your breathing passageways and will create sore throats
and sore nasal passages.
Nytrous Plus
was specifically created for automotive applications and is
available for sale to the public at many speed shops across the USA.
Safety Steps For Working With Nitrous Oxide
1.
Never
inhale
Nytrous Plus
(Nitrous oxide (N
2
O) for vehicular use) as continued exposure can
cause death.
Nytrous Plus
has a maximum of 100 parts per million (ppm) of sulfur dioxide and
will cause irritation to nose and throat passageways.
2. When working around any high-pressure gas including nitrous oxide, take all precautions to
ensure that exposure to nitrous oxide is minimized.
3.
Do not
vent nitrous oxide to atmosphere in confined spaces. Only vent nitrous oxide in
well-ventilated and open areas.
4. Liquid nitrous oxide can cause burns to human flesh so protect all skin in and around your
hands, arms and face. Wear safety glasses and rubber gloves to protect from liquid nitrous
oxide splatter.
5. When venting down the nitrous system, vent the line down closest to the nitrous bottle.
6.
Do not
use any form of Teflon tape as sealant on fitting connections. Use only Teflon paste.
7. When washing components, ensure the clean components are completely dry, free of oils, and
solvents. Failure to remove all liquids could cause component or system failure.
8.
Always
turn the bottle off before making any repairs to the nitrous delivery system.
9. To safely release nitrous oxide in a pressurized line;
a. Position vehicle in a well-ventilated, unconfined space.
b. Turn bottle off.
c. Slowly turn the nitrous feed line at the bottle open until you hear a light hissing noise.
d. Allow the entire nitrous pressure to vent from the line.
e. Perform your work on the system.
f.
Re-attach the nitrous line to the bottle.
g. Slowly open the nitrous bottle valve, listening for leaks.
h. Perform leak checks on all affected fittings and the bottle fitting.
