Mounting the Hardware
Installation of any nitrous kit begins with proper mounting and routing for the cylinder, solenoids, lines and switches. We believe the best approach to installing any nitrous kit is to install the pieces in the order the nitrous flows - from the cylinder to the solenoids. We don't know of any kit manufacturers who will tell you specifically where to mount each component for a particular make and model vehicle. While this is done to offer flexibility for different applications, it can certainly make it tough for anyone not familiar with nitrous operation. We've detailed in this article exact locations which should work well for any 1999-2004 Mustang GT.

On our '01 Mustang we mounted the bottle on the trunk floor, behind the passenger seats. Secure the brackets using the supplied hardware. For a clean look we cut slits in the carpet so the brackets would slip through and be out of sight. Note, the bottle orientation with the nozzle facing downward. This ensures the pick up tube inside the bottle is at the lowest position.	The next step is to route the 20 ft. braided steel line between the bottle and nitrous solenoid. The drain hole in the trunk of our '01 led right through the rear subframe. We fished out the line through this opening and ran it under the driver side of the car, securing it with clamps every few feet.
Getting the line into the engine compartment was a breeze as these Mustangs have a factory pass through in each corner of the engine compartment, which leads into the fender well, used for wiring. Note the rubber cap on the end of the line. This prevents debris entering the line until we are ready to connect to the solenoid.	Nitrous cylinders come with a saftey blow-off valve which releases the nitrous if bottle pressure exceeds 3000psi. Many racing bodies, such as the NHRA, however, require the vent to be directed outside the vehicle using a blow-down tube. We'll install a blow-down tube before running the car at the track.
On our '01 Mustang the best mounting location is right on the upper intake plenum, using the outer spring bracket bolt. Solenoids can be mounted in any position, including upside down. We ended up flipping ours over to avoid any potential hood clearance issues. Remember to also turn the solenoids around 180 degrees so the inlet and outlet sides point in the right direction.	The NitrousWorks kit is a "wet" fuel delivery system. Fuel is supplied to the fuel solenoid via the factory pressure test port in the fuel rail. The kit replaced the Schrader valve (top) with a -AN adapter (bottom.) The Schrader valve on '99-'01 Mustangs is located above fuel injector #5.
Before removing the Schrader valve ensure the motor is cool and then depressurize the rail by depressing the valve. Keep a rag nearby to soak up any fuel. Apply Teflon™ paste (not tape) to the threads of the new -AN fuel line adaptor and install into the fuel rail. Then install the braided line.	Drill a 3/8" hole in the intake tube and install the PowerWing nozzle. The orifice of the nozzle should face towards the throttle plate as shown so that the nitrous and fuel mixture spray into the engine. The nozzle can be secured into place using the supplied threaded fitting.
When the nozzle is positioned as indicated in step 8 the port nearest the throttle body is the fuel side. We marked it red to avoid confusion. We've installed 50 horsepower jets to start off with. Do not attach the fitting without installing jets first.	Attach the braided lines to the solenoids. The lines are prepared with red and blue connectors to indicate fuel and nitrous respectively.
