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 the front of
drivers side of the engine and the blue fitting faces the passenger side of the engine. Look at the brass
tubes, a properly oriented plate will have the nitrous tube above the fuel tube ensuring the angled orifices
machined into the tube face oriented to the floor of the intake manifold.
Use the following procedure to install the injector plate:
1. Remove the throttle body air cleaner.
2. Mark all of the vacuum lines and external connections attached to the throttle body and
disconnect them.
3. Disconnect the throttle linkage from the throttle body.
4. Remove the throttle body.
5. Remove the stock throttle body studs and clean the mounting surface.
6. Install the extended throttle body studs supplied with the nitrous system.
7. Install the injector plate and gaskets supplied on to the intake manifold.
8. Install the throttle body.
9. Re-connect linkage and all external vacuum lines.
Note: Every precaution has been taken to ensure the cleanliness of our components during
the assembly of your Edelbrock Nitrous System. However, because of the importance of
the jets and their calibration, extra care should be taken before you install your jets. Wash
them thoroughly with carburetor cleaner or another non-oil based cleaner, before installing
them into the plate.
2.10 Solenoid/Plate Plumbing Installation
1. Choose the final mounting location for your solenoids and mount them solidly.
2. Install the desired nitrous and fuel jets in the jet fittings of the plate. Remember, the red fitting is
for fuel and the blue fitting is for nitrous. Mixing the jets up when installing can result in serious
engine damage.
3. Using the braided steel line with the red ends, install the line on the red jet fitting on the plate and
run the other end to the fuel solenoid. Make sure that you do not use any thread sealant on these
types of fittings. Tighten both ends of the line.
4. Using the braided steel line with the blue ends, install the line of the blue jet fitting on the plate and
run the other end to the nitrous solenoid. Make sure that you do not use any thread sealant on
these types of fittings. Tighten both ends of the line.
