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 much like a supercharger
or a turbocharger does.
Nitrous Oxide is considered an “oxidizer” and not a fuel. 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 cause 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 (N2O) 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 loosen the nitrous feed line at the bottle 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. Tighten 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.

1.0 Introduction to your Edelbrock Single to Dual Stage Upgrade Kit
Within the pages of this manual is information, safety tips and operation instructions for your new Edelbrock Nitrous System. Watch
for these symbols to know where to go for information.
….There is safety related information here.
….shows where technical information about your vehicle or specific skills that may help during
installation.
….call Edelbrock Technical support hotline for more information.
1.1 General Information
The Edelbrock Performer RPM Single to Dual Stage Upgrade Kit (Part Number 70005) is intended for
use on domestic style V-8 engines using single square-flange 4 bbl. carburetors and Spread-bore 4
bbl. carburetors. Horsepower and torque increases can vary with equipment upgrades and modifications.
These types of systems utilize an adjustable plate that seats in between the carburetor and the carburetor mounting
flange on the intake manifold. The adjustability comes from the ability of the plate to accept different orifice-sized
jets. The plate has y-shaped jet fittings at opposite ends of the plate that control the amount of nitrous oxide and
fuel flow into the engine.
This system has been designed with some flexibility as to where certain components can be located to allow easy
installation on vehicles with upgraded or modified equipment. The solenoid and microswitch brackets are designed
to be manipulated (bent, cut, twisted, etc.) and the electrical components have properly sized and ample lengths of
wire.
Contact your local automotive store, motorcycle shop or race track for refilling of your bottle. Trust a professional
to properly fill your bottle and reference your installation manual when re-installing your filled bottle back into your
vehicle.
Always take care when handling a full bottle of nitrous oxide. Please reference this manual for further safety
measures to take during the handling of a nitrous oxide bottle.
Please follow all safety methods during the installation of your Edelbrock Nitrous System, and follow all vehicle
regulations and road laws when using your nitrous system.

1.2 Jet Map Information
Edelbrock engineering has conducted dyno testing with the Performer RPM II system to provide you with a baseline
jet map. Your jet map may change with the use of other components. These jet combinations are supplied with this
system to enable you to vary your engine’s power output.
Square Flange Jet Map
Dominator Jet Map
Jet Map Footnotes:
1. Use 1 heatrange colder spark plugs
2. Use 2 heatrange colder spark plugs
3. Use 92 octane pump gasoline or better
4. Use 110 octane race gasoline or better
5. Use a single plane manifold only at this power level
6. Advanced tuning required. Suggested timing adjustment is just a guideline. Engine component modifications may affect
final timing set point.
Edelbrock recommends an NGK spark plug with a heat range of -9 to -11 depending on the nitrous power level
being tuned. When in doubt, always go to the next cooler heat range plug.
The dyno tests were conducted at Edelbrock using a highly modified Big Block Chevrolet. Modifications included
Edelbrock intake manifold, cylinder heads, dyno headers, pistons, rods, crankshaft, and improved ignition. These
tests were conducted with 950 psi nitrous and 6.5 psi fuel pressure. All stated timing adjustments listed in the jet
map is where the motor being tested performed best. Final timing should be adjusted to achieve best power and/or
MPH per application. See section “5.0 Ignition Timing and Nitrous” for more information on timing selection.
Any variation in jetting patterns other than what is listed above and engine damage could occur. Please contact the
Edelbrock Technical Department with any questions you have concerning jetting patterns and their effects on engine
performance.
