N-TERCOOLER SYSTEM

INSTALLATION INSTRUCTIONS

The most important thing to do now is READ…
UNDERSTAND…AND …FOLLOW…these instruc­tions. If there is something you don’t understand,
STOP! Call the factory tech department for help. 9:
00 AM to 4:00 PM CST 940-767-7694.

The installation procedures are divided into 5 sec­tions. Please pay particular attention to each one:

1. Mounting the bottle

2. Routing the supply line.

3. Mounting the cooler ring

4. Wiring the system

5. Testing the system.

Before starting any installation steps:

1. Disconnect the negative battery terminal.

2. Never use Teon tape on any system ttings.
Tape debris will cause numerous problems rang­ing from fouled solenoids to blocked jets. Use a
thread sealer such as Permatex 14AR or equiva­lent Teon based sealant.

3. Have your bottle lled by a reliable source, being
sure it is lled to capacity with ltered “Nytrous
+” nitrous oxide or CO2. For lling station loca­tions log on to: www.nitrousexpress.com.

MOUNTING THE BOTTLE

The bottle should be mounted in the trunk area or
outside of the passenger compartment. If this is not
possible or practical a NHRA approved blow down
tube and vent tting (PN’s 11708, 11709) must be
installed. The positioning of the bottle should be as
shown in diagram “A”. This will allow the siphon
tube to be covered at all times.
The mounting brackets should be assembled on
the bottle with the short bracket approx. 2” from the
bottom.. Use this mock up as a template to locate the
four mounting bolt holes. The bottle should be secured
by a minimum of 4 “Grade 5” 5/16 bolts. Note: Before
drilling holes be sure to check for clearance beneath
the mounting surface i.e.: fuel tank, fuel lines, brake
lines.

ROUTING THE FEED LINE

NOTE: Place a piece of tape over both ends of
the hose to prevent debris from entering the feed line
during the routing process.

The feed line may be routed to the engine com­partment either through the passenger compartment or
under the vehicle. Route the line carefully to prevent
the possibility of restricting nitrous ow. If routed
under vehicle, locate and drill a  inch diameter hole
in a suitable area near the bottle valve for the main
line. Starting at the bottle nipple route the line to the
engine compartment. Following the factory fuel lines
is usually the best path. Note: Keep maximum clear­ance between all moving parts, suspension compo­nents and hot engine components, securing the supply
line where possible (“Zip-Ties” work best here).
Tighten the line to the bottle nipple securely. Be espe­cially careful of the feed line being near any “HOT”
electrical leads a spark will cause a permanent leak in
the feed line.

MOUNTING THE COOLING RING

Assemble the solenoid to the cooling ring, the
1/8 NPT discharge port on the bottom of the solenoid
mounts directly to the cooling ring. Thread the xD­4 lter tting into the inlet port of the solenoid, the
supply line will connect here. Teon based sealant
should be used to avoid leaks. Mount the NX cooler
ring on your intercooler using the supplied zip ties, do
not over tighten, intercooler damage may result. Con­nect the supply line to the inlet port on the solenoid at
this time, tighten securely.

WIRING THE SOLENOIDS

1. Mount the red arming switch within easy reach,
and plain sight of the driver.

2. The supplied wide-open throttle switch is univer­sal in design and can be mounted in a variety of
positions. The mounting plate is designed to be
easily bent cut or twisted to work in any applica­tion. The trigger arm on the micro switch may be
bent twisted or cut to aid in ease of installation.

3. The best power source for the system is the “Posi­tive” post on the battery. Do not try to “Splice”
into the factory wiring harness for a power supply,
this will not have adequate amperage to operate
the solenoid.

4. Follow diagram “C” when wiring the system, the
relay must be used in all applications.

5. Solder all connections for a permanent trouble
free installation.

6. The solenoid is rated only for intermittent duty.
Do not engage solenoid for more than 20 con­tinuous seconds. Solenoids that have “burned or
scorched” electro-magnets will not be replaced
under warranty.

COMPLETING AND TESTING THE SYSTEM

1. After all components have been assembled on the
vehicle and each piece has been veried for cor­rect installation and the wiring has been rechecked
and veried to be correct, it is time to test the
system.

2. Do not open the bottle valve at this time.

3. Reconnect the negative battery cable.

4. Using the red, lighted toggle switch “Arm” the
nitrous system.

5. Test the solenoid operation by “Engaging” the
activation or WOT switch. The solenoid should
“Click”. If it does not, re-verify all electrical con­nections and wiring diagrams.

6. Open the bottle and check all connections for
leaks. If “ice” appears on any connection this
indicates a leak. Retighten any tting or connec­tion that leaks and recheck.

7. Choose a suitable testing area, your local racetrack
is the best choice. Drive the vehicle to verify all
operations are normal and the throttle linkage is
operating properly.

8. Pre-stage the vehicle, arm the system, purge the
air from the supply line, if an optional purge valve
is used, using 3 one-second bursts from the purge
button. Stage and launch the vehicle.

9. Make a full throttle pass and shut the engine off,
check all spark plugs to be sure the decrease in
inlet temperature has not resulted in a lean condi-

tion. If a lean condition is detected adjustments
must be made in the engine fuel curve.
