Nitrous Express DUAL STAGE CARBURETOR SYSTEMS - Manual

SUPPLEMENTAL INSTRUCTIONS FOR DUAL
STAGE EFI SYSTEMS
“VERY IMPORTANT”
A stock fuel pump will not work with a dual stage
system. An after market pump is required. The
minimum pump capacity is 190LPH.
1. Drill two 9/16 holes in the flexible duct that con-
nects the air cleaner to the throttle body. The
location of these holes is not critical however they
should be as close to the throttle body as practical.
Install the nozzle adaptor fittings and thread the
NX Shark nozzles into the adaptors. Be sure the
discharge side of the nozzles is directed toward
the throttle body.
2. Proceed with the installation as if you are install-
ing two separate nitrous systems, per the main
instruction leaflet.
3. Using the lines and tee’s furnished with your
system connect the fuel solenoids inlets together
and then connect to the fuel supply. Connect
nitrous solenoids together on their inlet sides and
then connect them to the nitrous supply hose.
When wiring the dual stage connect the 1st stage to
the wide-open throttle switch. Connect the second
stage to the push button trigger switch supplied in
your system. The push button should receive its
power from the second stage-arming switch. That
arming switch should receive its power from the
red relay wire from the first stage. The 2nd stage
should/can only be activated if the first stage has
been activated. Follow the wiring diagram in the
instruction leaflet

system connect the nitrous solenoids together
on their inlet sides and then connect them to the
nitrous supply hose. Fuel solenoids inlets will go
to there respective regulators (PN 15951).
4. When wiring the dual stage connect the 1st stage to
the wide-open throttle switch. Connect the second
stage to the push button trigger switch supplied in
your system. The push button should receive its
power from the second stage arming switch. That
arming switch should receive its 12volts source
from the relay’s red wire on the first stage. The
2nd stage can/should only be activated if the first
