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.

1.1 General Information
The Edelbrock 4.6L Mustang Performer EFI Nitrous System (Part Number 70405) is designed for 1999-Later Mustang vehicles equipped with stock or slightly modified 4.6L engines that utilize the returnless style fuel system. Horsepower and torque increases can vary with equipment upgrades and
modifications.
The system utilizes one nozzle that is installed in the intake boot just after the MAF (mass air sensor) filter and before the throttle body. The additional fuel needed is supplied by the vehicle’s standard fuel system.
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.
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.
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 Edelbrock 4.6L Mustang Performer EFI system to ensure
the horsepower increase with the nitrous system is as intended. On a typically stock 4.6L Mustang engine, you can expect the following approximate power gain:
Nitrous Jetting
Approx. HP Gains Final Air/Fuel Ratio Potentiometer Setting
.042 80hp 13.5:1 Fully Counter-Clockwise
The dyno tests were conducted at Edelbrock using a stock 4.6L engine. These tests were conducted with 950 psi nitrous bottle pressure.
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:
• System Jetting
Never exceed the recommended jetting!! Excessive jetting will result in severe engine damage.
• 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.
• Ignition Components
Most aftermarket performance chips increase the vehicle’s ignition timing, which can cause detonation with the use of nitrous oxide. Please consult with your chip manufacturer on information regarding the compatibility of your chip with nitrous oxide use.
If your vehicle is equipped with platinum type spark plugs, we highly recommend they be removed and replaced with the equivalent standard type spark plug.
• 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, manifolds can all add to the performance of a nitrous oxide injected engine.

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.
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 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 away from the driver’s compartment.
