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 2-Stage Performer RPM Nitrous System

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 2-Stage Performer RPM Nitrous System (Part Number 70003 and 70004) is intended for use on domestic style V-8 engines using single square-flange 4 bbl. carburetors (Part Number 70003), and Spread-bore 4 bbl. carburetors (Part Number 70004). 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

Edlebrock engineering has conducted dyno testing with the 2-Stage Performer RPM System to provide jetting maps for the two separate plates at different jetting levels. These jet combinations are supplied with this system to enable you to vary your engine’s power output. On a typical mildly-modified 350 cubic inch engine, you can expect the following approximate power gains for each of the jetting levels:

The dyno tests were conducted at Edelbrock using a mildly-modified 350 cubic inch engine. Both dual plane and open plenum intake manifolds were tested to ensure validity of jet maps for each horsepower setting. Modifications included Edelbrock intake manifolds, Edelbrock aluminums heads, dyno headers, and improved ignition. We also used different grades of fuel and colder plugs during the testing. Final timing should be adjusted to achieve best power and/or MPH per application. See section

“Ignition Timing and Nitrous”

for more information on timing

selection.

These jet patterns are designed to be rich and will provide the above listed power settings under normal operational usage of this system. 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.

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 and engine 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 0.1 gallons per hour per horsepower at rated pressure. The testing at Edelbrock was conducted with a fuel pressure of 6.5 to 7 psi. Any variation 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. Edelbrock recommends setting your fuel pressure flowing. We offer a flow tool (Edelbrock Part #76506) to help in this process.

Performer RPM Fuel System Requirements:

When using the Performer RPM series kits, the potential horsepower gains are quite high. The critical area for continued success with your nitrous system lies in the fuel system. In most cases, an auxiliary fuel supply system will be 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 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 setting.

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 maintain the same fuel burn rate every time. Please refer to the jet map footnotes for information on what fuel types and fuel qualities that were used during the testing here at Edelbrock.

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. Ignition upgrades, intake manifold upgrades, and fuel controls and fuel pumps can all add to the performance of a nitrous oxide injected engine.

Cast Pistons/Hypereutectic Pistons:

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

2.0 Nitrous System Installation

2.1 Nitrous Bottle Installation

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 the tech line.

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. The internal type 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. Do not 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.

DDoo nnoott

attempt to grind off or destroy any imprinted markings on the face of the bottle.

DDoo nnoott

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 association or local racetrack for any rules regarding bottle installation. Most associations require the bottle be mounted within the confines of the safety roll cage, with the safety pressure relief cap vented outside the driver’s compartment.
