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.

1.2 Jet Map Information Edelbrock engineering has conducted dyno testing with the Performer RPM system to provide jetting maps for two 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 two jetting levels: Pro-Flo Jet Map #70070 Nitrous/Fuel Jetting Approx. HP Gains Final Air/Fuel Ratio Timing Adj.

2.0 Performer RPM System Installations 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

2.2 Bottle Orientation Bottle placement is critical to the performance of your nitrous system. It is important to understand how the bottle valve and siphon tube are assembled to properly orient the bottle in your vehicle and ensure that it picks up liquid nitrous while undergoing acceleration. All nitrous bottles are assembled so that the bottom of the siphon tube is at the bottom of the bottle, opposite the bottle label. An Edelbrock nitrous bottle cannot be mounted upside-down.

2.3 Nitrous Bottle Installation After you have determined the location and orientation of the nitrous bottle, use the following procedure to install the bottle: 2.3.1 Street Car Installations 1. Disconnect vehicle’s battery. 2. Determine the location of the bottle within the confines of the rear of the vehicle. 3. Once a mounting location has been determined, raise the vehicle (following all safety practices involved in working on a vehicle from under the vehicle) and verify that there are no fu

2.4 Nitrous Feed Line Mounting 1. Determine the route your main nitrous feed line will follow. Ensure the path does not route the nitrous feed line too close to the exhaust system, suspension, electrical lines/components or tires. 2. Attach nitrous supply line to bottle. 3. Feed nitrous line along proposed route. 4. Secure nitrous supply line to underside of vehicle. Note: Stainless steel covering of the main nitrous feed line is very abrasive.

2.6 Nitrous Solenoid Mounting and Installation 1. Hold the nitroous solenoid securely (like in a bench vise) being careful not to harm the solenoid or block the inlet outlet of the solenoid. 2. Install nitrous filter fitting (Blue fitting 4AN X 1/4 NPT) using liquid Teflon in the inlet port of the nitrous solenoid. 3. Install 4AN X 1/8 NPT (Blue straight fitting) using liquid Teflon in the outlet port of the nitrous solenoid. i. Remove nitrous solenoid assembly from vise. ii. Attach solenoid-mou

2.9 Nitrous Injection Plate Installation The Edelbrock Nitrous System injection plate is a precision-designed CNC-machined component. It has been designed to safely introduce a precise, metered nitrous and fuel signal to promote proper mixing and distribution into the intake manifold. The jet map on page 5 will give you the proper jets to use for each of the power levels available for this plate. The jet fittings are color-coded for use with nitrous (blue) and fuel (red). The red fitting faces t

2.11.1 Nitrous Electrical System Installation Procedures Determine the location of the Relay and Fuse Holder wire harness. Most common installations locate these components inside the driver’s compartment and close to the fuse panel under the dash. You can also mount the Relay and Fuse Holder and harness close to the battery. However, these connectors are water-resistant not waterproof, so care is required when mounting this assembly under the hood of your vehicle. Wire Schematic Origin and D

2.13 Arming Switch The arming switch is a red, lighted switch that is a “MASTER” arming switch for your nitrous system. Without it, your nitrous system would be “on” all of the time and capable of engaging anytime you go to wide-open throttle conditions with your vehicle. The switch, when in the “armed” position, is well lit. Therefore, it should be placed in an obvious position well within the line of sight and easy reach of the driver. 2.14.1Arming Switch Installation 1. Locate the final posit

2.14 Microswitch Installation and Wiring (continuation)... Due to the wide variety of throttle linkage combinations in use, it is impossible to supply a microswitch bracket custom tailored to each application. The universal bracket supplied will need to be modified to fit your specific application. The microswitch bracket supplied is drilled to permit many different switch mounting positions. This flexibility allows for the microswitch to be positioned in such a manner to engage the throttle b

4.0 Baseline Tuning Suggestions Utilizing nitrous oxide as a power adder is similar to a supercharger or a turbocharger in that it increases the amount of air an engine can get from atmospheric conditions. There are some significant differences though: 1. The “air” in nitrous oxide is very oxygen rich. This oxygen is of a much higher density, so the opportunity to extract very high quotients of power is very high. 2. Nitrous oxide injection does not have a parasitic load factor associated with
