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 effected fittings and the bottle fitting.

Anytime you have questions or concerns with your Edelbrock Nitrous System,

1.0 Introduction to your Edelbrock Performer RPM II Nitrous System

….about this manual!

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 II Nitrous Systems are intended for use on domestic style V-8 engines using
single Dominator-flange carburetors (Part #70081, #70083, #70086) and square-flange 4 bbl. carburetors
(Part #70080, #70082, #70085). Horsepower and torque increases can vary with engine displacement, equipment

upgrades and modifications. Approximate power increase estimates can be made based on the mass flow of nitrous oxide
into the engine.

These types of systems utilize an adjustable plate that sandwiches in between the throttle body and the throttle body
mounting pad on the intake manifold. The adjustability comes from the ability of the plate to accept different orifice-sized
jets. The plate has 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 within the engine
compartment. The electrical components have properly-sized and ample lengths of wire for some flexibility on where
voltage signals are intercepted on the electrical system.

The solenoid and microswitch brackets have a universal shape to allow for adjustability in placement and location of these
components. The solenoids have ample feed line lengths for many different manifold, air cleaner, throttle body
configurations and the microswitch bracket will allow for several different positions.

This system includes the bottle (shipped empty), bottle feed line and universal footprint steel bottle brackets. The
mounting brackets also include rubber insulators to protect the surface of your nitrous bottle while mounted in the
brackets. When installing your nitrous bottle, pay close attention to the installation instructions for the location of your
bottle. Make sure that the installation of your bottle does not interfere with any systems that may lie under the location
where you plan to drill holes for mounting the brackets.

Call 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. These jet combinations are supplied with this system to enable you to vary your engine’s power output. On a typical
mildly to highly modified 350 or larger cubic inch engine, you can expect the following approximate power gains for each
of the jetting levels:

Performer RPM II Jet Map

2-Stage Performer RPM II Jet Map

JET MAP NOTES:
Pressures: Maintain 6.5 psi fuel pressure and 950 psi nitrous oxide bottle pressure for safe and effective operation.
Spark Plugs: Two heat ranges colder than an equivalent naturally aspirated engine would use.
Fuel: 110 octane or higher race gas is required to prevent detonation.

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. All stated timing
adjustments listed in the jet map are 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 variations in jetting patterns other than what is listed above and engine damage could occur. Please contact Edelbrock
Technical Department with any questions you have concerning jetting patterns and their effects on engine performance.

Edelbrock recommends an NGK spark plug with a heat range between -9 and -11, depending on the power level being
used. When in doubt, always go to the next cooler heat range.

The Performer RPM II Series Nitrous Systems are intended for single-plane manifolds only. Do not use a
dual-plane manifold with the Performer RPM II Series Nitrous Systems. In testing, we found that dual-plane

manifolds have some distribution problems at these super high flow rates that could cause serious engine damage.

1.3 Engine Operation Considerations

When used correctly, nitrous oxide safely elevates cylinder pressures and temperatures while increasing combustion rate.
These characteristics make the engine more sensitive to detonation. To ensure proper performance, engine and drive line
life, the following tips are suggested:

• Adequate Fuel Pressure and Delivery

When designing your fuel system, plan on your pumps and lines flowing at least 0.10 gallons per hour per horsepower.
The testing at Edelbrock was conducted with a fuel pressure of 6.5 psi. Any variations from this fuel pressure
will cause your final air/fuel ratio to change. Consult our Technical Department for any questions on fuel pressure and its
effects on final air/fuel ratios when using nitrous oxide.

• Performer RPM II Fuel System Requirements

When using the Performer RPM II Series Kits, the potential horsepower gains are extremely high. The critical area for
continued success with your nitrous system lies in the fuel system. In the case of the Performer RPM II Series Nitrous
Systems, an auxiliary fuel supply system is a required addition to your nitrous system. A high flow electric fuel pump and
high capacity adjustable fuel pressure regulator are both recommended to ensure the fuel flow rate is enough to ensure
proper system operation. The minimum size we recommend for the fuel inlet feed line is a -6 (3/8” inch), with a size of

-8 (1/2” inch) recommended for the higher horsepower settings.

• Performer RPM II System Monitoring Requirements

Fuel pressure and nitrous pressure gauges are very important. Your fuel pressure must be set properly and a gauge is the
only sure way to monitor system performance. The same is true of the nitrous bottle pressure. A nitrous pressure gauge
is the only way to ensure that your system calibrations are within the parameters required of your horsepower settings.

• Fuel Quality

Because Nitrous oxide is an oxidizer, fuel selection is critical. Both octane and fuel consistency affect fuel burn rate. The
oxidizer quality of nitrous oxide will accelerate the burn rate, so we recommend a high quality of gasoline. We also
recommend you use the same grade of gasoline every time you use your nitrous oxide system. This will help maintain
the same fuel burn rate every time.

• Forged Pistons

With all nitrous oxide applications, forged pistons are highly recommended. Because of heightened potential for
detonation, cast pistons are more prone to failure and cannot handle horsepower increases over 125hp.

Due to this fact,

the Performer RPM II Nitrous System requires that the engine has forged pistons. Never initiate your nitrous
system before you are at full-load, wide open throttle conditions. Cast pistons will not be able to survive this kind of stress.

• Engine System Upgrades

With all performance modifications, complementary system upgrades will always serve to elevate the consistency and
longevity of an engine, especially when using nitrous oxide as a power adder. Modifications such as ignition upgrades,
free-flowing exhaust, camshafts, cylinder heads, and manifolds can all add to the performance of a nitrous oxide-injected
engine.

Anytime you have questions or concerns with your Edelbrock Nitrous System,

please call our technical support hotline at

1-800-416-8628 before you start your engine.

2.0 Performer RPM II Nitrous System Installation

2.1 Nitrous Bottle Mounting

The nitrous oxide storage cylinder is typically called a “nitrous bottle”. It is an aluminum cylinder, designed and
manufactured to withstand very high pressures. The valve on top of the bottle is a high-flow design that allows easy
opening and closing which controls the nitrous flow to the engine compartment.

Accurate calibration of your nitrous system depends on the bottle remaining at a stable temperature. In vehicles (such as
Corvettes) where the bottle must be mounted in an area subject to direct sunlight, it is suggested that the bottle be
shielded with a bottle blanket.

If the bottle is mounted inside the passenger compartment or in a space that has access to the passenger compartment
such as hatchbacks or vehicles that feature fold down rear seats, the pressure relief device (PRD valve) must be vented
externally from the cockpit. This procedure will prevent the passenger compartment from filling with a cloud of nitrous
oxide, should the safety pressure relief valve rupture. For more information, please contact our Technical Department.

Special consideration should be made to protect the bottle installation by not placing the bottle in
a known crumple or crash zone within the vehicle. At no time should the bottle be mounted within
the seating area of the passenger compartment of a street-driven vehicle.

Here is the Performer Bottle Valve. Installed on all bottle valves used in Edelbrock Nitrous Systems,
is a Pressure Relief Device or “PRD”. It is a safety valve designed to vent the contents of the bottle
into the atmosphere in case of a catastrophic event like a collision. It is also installed to prevent
the over-pressurization of the bottle. Unsafe bottle pressure is caused by over filling or elevated
bottle temperatures.

There are two types of PRDs. Internal piping and external piping. Internal requires no additional
parts. The external type requires a safety blowdown tube designed to route the gas, if the PRD
happens to rupture to the outside of vehicle. The internal type is design to vent directly off the
bottle into the atmosphere.

It is illegal to tamper with or remove this device.

Bottle Safety Information

1.

DDoo nnoott

attempt to remove the bottle valve. Please return your bottle to Edelbrock if service is required to

the siphon tube inside the bottle or the bottle valve itself.

2. Never heat the outside of your nitrous bottle with an open flame like that of a torch.

3. Do not strike the surface of your nitrous bottle with a heavy or sharp object.

4. Do not drop your nitrous bottle.

5. Do not attempt to grind off or destroy any imprinted markings on the face of the bottle.

6. Do not remove, modify or otherwise tamper with the safety valve on the bottle valve.

7. Do not attempt to use a bottle that has been damaged or tampered with.

Racing Vehicles

Before you mount a nitrous bottle in a vehicle intended for use in racing or sanctioned events, check with the sanctioning
