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 the engine and the blue fitting faces the rear. The plate has been etched indicating
which of the gasket surfaces face upward. 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 orient to the floor of the intake manifold.
Use the following procedures to install injector plate:
1.
Remove carburetor air cleaner.
2.
Mark all vacuum lines and external connections attached to carburetor and disconnect
them.
3.
Disconnect throttle linkage from carburetor.
4.
Disconnect fuel line from carburetor.
5. Remove
carburetor.
6.
Remove stock carburetor studs and clean mounting surface.
7.
Install extended carburetor studs supplied with kit. (70050, 70053 Systems)
7a. Install extended carburetor studs in front of manifold, and use extended bolts
when re-attaching carburetor on the rear of carburetor. (70051 system)
8.
Install injector plate and gaskets supplied on intake manifold.
9. Install
carburetor.
10. Re-connect linkage, all external vacuum lines and fuel line.
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.
2.11 Solenoid/Plate
Plumbing Installation
1. Choose the final mounting location for your solenoids and mount them solidly.
2. Install desired nitrous and fuel jets in the jet fittings on the plate. Remember the red fitting is
for fuel and the blue fitting is for nitrous. Mixing the jets up during installation can cause
engine damage.
3. Using the braided-steel line that has 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 that has the “blue” ends, install the line on 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.
