TESTING THE SYSTEM
At this point both solenoids should be tested for proper operation. Note: (Be sure the nitrous bottle is off
and there is no pressure in the N2O supply line). If you are using a fuel safety pressure switch you must
use a jumper wire between the NO and C terminals when testing the solenoids. To test, turn on the
vehicles key but do not start the engine. Turn the “arming” toggle switch to the ON position and push the
accelerator pedal to the floor. A clicking sound from the solenoids should be heard as the gas pedal is
pushed on and off past 80% throttle. IMPORTANT: Make sure that both of the solenoids are clicking! If
no sound is heard or only one of the solenoids is working, check all wire connections and the wiring
schematic for proper connections. Note: The nitrous and fuel solenoids are rated only for intermittent
duty. Do not engage either solenoid for more than 20 continuous seconds. Solenoids that have “burned or
scorched” electro-magnets will not be replaced under warranty.
Once proper operation is verified, connect the nitrous supply line to the bottle and FULLY open the bottle
valve and carefully check connections on the nitrous side of the system for leaks and retighten fittings if
necessary. With no leaks detected, start the engine and thoroughly check the fuel connections for leaks.
Do not attempt to start engine if nitrous has been accidently injected into the intake manifold. Disconnect
all of the coil wires and crank the engine several revolutions with the throttle wide open to clear the
engine of all nitrous before attempting to start engine.
USING THE SYSTEM
All NX systems are designed for off road usage. Use extreme caution and observe all safety precautions
(see your vehicles owner’s manual). Select a suitable test area; your local racetrack is best. Arm the
system with the cockpit N2O arming switch. Gently launch the vehicle, gradually accelerating to wide-
open throttle. When WOT is achieved a noticeable surge of power should be produced. If not stop and
