4.0 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.
4.1 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 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 the microswitch, which will open the nitrous
solenoids and activate the voltage booster unit. Listen for a loud click or hold the solenoids while you activate
the microswitch. The engine speed will decrease if the voltage booster unit and delivery system are performing
properly. If not, refer to the “TroubleShooting Guide” located in the back of this manual.
4.2 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.
