Nitrous Express N-TERCOOLER SYSTEM - Manual (Page 2)

2. The supplied wide-open throttle switch is univer-
sal 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 applica-
tion. 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 “Posi-
tive” 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 con-
tinuous 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 verified for cor-
rect installation and the wiring has been rechecked
and verified 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 con-
nections 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 fitting or connec-
tion 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.
