Hidden Ford Nitrous Oxide System - The Street Racer's Special - Tech

Holliday removed the upper intake manifold so we could access the vacuum hook-ups underneath it.

Delivery of the juice is conveniently through the vacuum port under the manifold. Remove this piece so a hole can be drilled out and the air opening can be angled properly.

Minor drilling was required in order to fit the nitrous line.

The nitrous line fits in perfectly and is masked using a vacuum hose.

Nitrous exits the vacuum hook-up from this hole and is sprayed into the main, center runner of the intake manifold.

The line going to the fuel-pressure regulator had to be T'd off the normal signal line. We had to use the T-fitting because it is predrilled by NOS to have the proper orifice to regulate the amount of nitrous going to the regulator. It is designed to spike the fuel pressure to 80 psi.

We spray painted the brass fitting in flat black and positioned it under the manifold in such a way that it could not be seen, even when using a flashlight.

The vacuum line was connected to the Kirban adjustable fuel-pressure regulator.

With the installation of the nitrous lines completed, the JPC crew turned their attention to the wiring. A power source was needed, so we chose to use the defroster switch as our means of activating the system.

A single, 16-gauge wire powers up the two solenoids.

The solenoids are hidden in the doorframe.
