Part 10: Sneaky Shooter - Stealthily Adding Nitrous
Packin' Horsepower in Your Air Cleaner
June 01, 2003
If you mount the solenoids according to the instructions, this is allyou have inside the air cleaner. That leaves the stainless steel braidedlines outside where they can be seen.

Instead of using the Holley-supplied solenoid bracket, we mounted oursolenoids to the bottom side of the air-cleaner base. We then drilledholes in the down-swept part of the base to allow the stainless steelbraided lines to pass through to the inside. Make sure you use a rubbergrommet in the hole you drill to protect the line from the metal edge ofthe hole.

We welded these tabs on the inside of the air-cleaner base so we couldmount the 90-degree AN flare to compression fitting. The braided linesthen came through the holes we drilled and mounted to the AN side of thefitting. Note also that we plumbed our lines from the fitting to theinjector nozzle.

Here is the completed air-cleaner assembly. We slipped the injectornozzle over the air-cleaner stud and secured it with a 1/4x20 nut. Thewire draping across the carb throat is the Thermal Safety Switch (TSS).In case of a carb fire, the thin resistor is burnt, stopping the flow offuel/nitrous into the carb. The TSS is the ground for the solenoids.

Bottle mounting is crucial to ensure the most liquid nitrous is removedfrom the bottle. It is best to mount the bottle with the valve handlefacing the front of the car and straight up. We wanted to hide ourbottle, and this meant turning it parallel to the axle. To do this, thevalve handle on the bottle must be tilted at a 45-degree angle towardthe front of the vehicle. We went one step farther and mounted ourbottle inside an old duffel bag in the trunk. If somebody wants to seeinside your trunk, all that's visible is a duffel bag.

Our nitrous line was run from the bottle, through the back of the duffel bag, and up through the inside of the car on the driver side, coming through the firewall, and ending at the carb.

From the carb to the firewall, we covered the nitrous line with a section of rubber fuel line. This not only protects it, it hides it, too.

We decided to mount the WOT micro switch on the passenger side of the carb to help conceal it. The mounting necessary to place it on the driver side (to clear the throttle mechanism) would be too revealing. We used a bottoming tap and tapped one of the small holes--for choke mounting--between the primary and secondaries.

We then used a small piece of tubing to space the switch out from the carb body. When the throttle is pasted to the floor, the secondary throttle blades activated the switch. You may need to play with the positioning of the switch to line it up correctly.
