Step 3 Nozzle Selection
Nozzle sizing is a function of horsepower, which approximates the engine airfl ow, and boost, which approximates
intake charge heat.
Recommended starting points:
250 - 350 RWHP: 175 ml/min nozzle.
350 - 475 RWHP: 375 ml/min nozzle
475 - 600 RWHP 625 ml/min nozzle
TECH TIP: Seal the nozzle into the nozzle holder using the included GOOP sealant. Using a sealant that is not
permanent will allow for nozzle changes during tuning. Simply remove the nozzle, clean the threads, and reinstall
using sealant.
Assemble desired nozzle into nozzle holder using GOOP sealant. The end of the nozzle with the fi ne mesh screen
is to be inserted into the nozzle holder. Torque 1/2 turn past fi nger tight. Do not use Tefl on sealants on NX
fi ttings.
NOTE: If nozzle is mounted lower than the reservoir, a Solenoid Upgrade (#15055) must be used to prevent
draining.
Step 4 Nozzle Mounting
The nozzle assembly should be installed 90° to the direction of airfl ow. On round intake tubes, this is 360° around
the tube meaning the nozzle can be mounted in any direction. This will ensure maximum cooling as the nozzle
sprays in a cone pattern. Be sure that the nozzle tip is fl ush with the inside wall of the tube, or even projecting into
it slightly to ensure no interference in the spray pattern. Make sure the nozzle is the highest point in the system
as well.
Drill and tap (11/32” pre-drill, 1/8”-27 NPT tap) air inlet tube as close as possible to throttle body/throttle plate.
