1972 Chevy Nova - NOS Install - Bottled Fun!

Next, we mounted the fuel and nitrous solenoids onto the bracket by screwing them into place. We also went ahead and installed the fittings with a little pipe dope for a good seal.

To mount the solenoids on the intake manifold, we bent and clocked the brackets to fit our needs.

We then installed the supplied AN-4 stainless braided lines to the solenoids and routed them cleanly for the NOS plate (blue for nitrous and red for fuel).

We then installed the supplied AN-4 stainless braided lines to the solenoids and routed them cleanly for the NOS plate (blue for nitrous and red for fuel).

With the lines connected to the solenoids, we placed the 55/35 (nitrous/fuel) jets into place and finished by connecting the lines onto the plate. This kit is adjustable from 100-150hp levels; we went straight to the middle setting and tried out the 125 shot.

To fuel the nitrous plate, we routed the fuel line from the opposite side of the fuel solenoid and connected it to the Schrader valve on the factory fuel rail. Make sure the line doesn’t kink anywhere.

For the nitrous feed line, we covered both ends with tape to prevent any dirt or grease from getting into it, and routed it down the rear of the engine to the undercarriage of the car to the trunk area. With the lines situated, we connected one end to the remaining port on the nitrous solenoid.

We were going for an unassuming look, so we connected the ground wire and ran our power wires inside the chassis. None would be the wiser of what this 5.3L is capable of.

Moving to the trunk, we first had to mount our bottle brackets. You also need to have the valve end of the bottle angled upward with the knob at its highest point; this will ensure the siphon tube is positioned correctly at the base of the bottle.

To complete the system, we drilled two holes to accommodate the blow-off tube (NHRA requirement) and the nitrous feed line. While it doesn’t show here, we also installed a rubber O-ring to prevent any chaffing of the feed line and the blow-off tube.

To complete the install, we mounted our arming switch and made sure it was within arm’s reach when belted in. To test the system, we fired up the motor with the nitrous bottle closed and tapped the microswitch. This should allow a small amount of extra fuel to be released, which will cause the engine to sputter. Remember to tap, not push and hold. After checking for fuel leaks with the engine running, we could open the bottle valve and listen for leaks in the feed line. No leaks detected—we were good to go! CHP
