2.4 Spray Nozzle Installation—Kit Number 05176NOS only
1.
Find a suitable location for the fan spray nozzle in the intake inlet duct. Check for interference between the spray nozzle
and the nearby components. The recommended location for the nozzle is generally 6-8 inches before the throttle body.
NOTE:
On vehicles that feature mass air flow sensors, the nozzle needs to be mounted between the sensor and the throttle
body (downstream of the sensor).
2.
Remove the rubber air inlet duct from the engine.
CAUTION:
Debris from drilling can cause severe damage to the engine. When drilling the spray nozzle hole, position
a towel carefully to prevent debris from contaminating your engine.
3.
Drill a 7/16” hole perpendicular to the inlet duct centerline through the inlet duct.
4.
Insert the nitrous spray nozzle adapter (6) into the 7/16” hole with the head on the inside of the duct.
CAUTION:
Severe engine damage can occur if the spray adapter/nozzle assembly works loose from the air inlet duct.
Ensure that the nitrous spray nozzle adapter is SECURELY tightened in the inlet duct.
5.
Use Loctite or a similar compound on the spray nozzle adapter threads and securely tighten the spray nozzle adapter nut
(7) to the spray nozzle adapter.
6.
Remove all debris from the air inlet duct.
7.
Mark the discharge side of the fan spray nozzle (8) with a marker to identify the direction of the nozzle discharge.
8.
Install the fan spray nozzle in the spray nozzle adapter with the discharge side pointed at the throttle body.
NOTE:
The Rubber Air Inlet duct is secured in place in Section 2.10.2.
2.5 Solenoid and Regulator Mounting—Kit Number 05176NOS only
Use the following procedure to install the nitrous solenoids.
CAUTION:
Do not overtighten the vise in the following procedure, or the solenoid will be damaged.
NOTE:
Apply Teflon-based paste to all pipe thread fittings before assembling the solenoids and regulators.
1.
Clamp one nitrous solenoid (9) base in a bench vise.
2.
Thread one side of the solenoid TEE (10) into the solenoid outlet port. The 1/8” NPT port should be facing outward, as
shown in Figure 4.
3.
Thread the other side of the solenoid TEE into the inlet port of the second nitrous solenoid. Rotate the second solenoid, so
that it is parallel to the first solenoid.
4.
Line up the bolt mounting holes on both solenoids with the holes in the solenoid bracket (11).
5.
Install the nitrous filter fitting (12) into the first nitrous solenoid inlet port.
6.
Install the 1/8” NPT nipple (13) into the nitrous pressure regulator (14) inlet port (bottom).
7.
Loosely thread the nitrous pressure regulator/nipple assembly into the solenoid TEE open port. If the regulator interferes
with the solenoid coils, the coils may be temporarily removed.
8.
Thread the 1/8” NPT-to-3/16” hose barb fitting (15) into the regulator outlet (side port).
9.
Attach the solenoid-mounting bracket to the nitrous solenoids.
10. Thread the 1/8” NPT - 3AN male fitting (16) into the second nitrous solenoid outlet port.
11. Remove the assembly from the bench vise.
12. Ensure that the 2 ft. 3AN x 1/8” NPT nitrous feed line (16) provided will reach the nitrous nozzle from the mounting location
on the driver’s side inner fender.
13. Attach the nitrous solenoid/bracket assembly to the driver’s side inner fender.
