3.0 Before You Run Your Vehicle Using Your Edelbrock Nitrous System
You have just completed the installation of your Edelbrock Nitrous System. It is time to perform some basic system checks
to ensure all of the work you have done is correct and ready to operate properly. The following procedure is designed to
validate the operation of your nitrous system before operating your vehicle:
Note: Before performing steps 1 through 4, make sure that the nitrous bottle is closed and main
nitrous supply line is empty of any nitrous.
3.1 Fuel System Check
1. Hook up all battery leads.
2. Double-check all wires and leads for signs of heat and proper connections.
3. Start your vehicle.
4. Check all fuel lines and fittings for leaks.
5. Switch master arming switch to the “on” position (switch should now glow red). Make sure the nitrous bottle is
closed and the main feed line are completely empty of ANY nitrous! Raise the engine speed to above 2000
RPM. Briefly depress the activation arm on microswitch, which will open the fuel and nitrous solenoids. Listen for a
loud click or hold the solenoids while you active the microswitch. Engine speed should decrease if the fuel solenoid
and delivery system are performering properly. If not, refer to “Trouble Shooting Guide”.
3.2 Nitrous System Check
1. With the vehicle's engine running, slowly open nitrous bottle valve.
Note: There should be no change in engine idle speed. If idle speed changes, close nitrous bottle valve immediately
and refer to the "Troubleshooting Guide" section.
2. Inspect nitrous lines and fittings for leaks using a soapy water mixture and a small brush.
3. If any of the fittings/connections show bubbling around the attachment nut or on the threaded area of the fitting, shut
the nitrous bottle valve off immediately and dry the fitting before attempting any service to that particular fitting
connection.
4. If the engine idle does not come up, and all of the fittings appear to be leak-free, you have successfully completed
the installation of you Edelbrock Nitrous System.
