Shown above is a typical EFI solenoid assembly using an unmodified EFI solenoid bracket as well as an exploded view of the nitrous
solenoid assembly. Modifications performed to a solenoid bracket depend on many factors. When mounting the solenoid assembly
on a vehicle, considerations should be taken regarding any potential interference with the vehicle’s systems or components.
The line length between the Performer RPM EFI solenoid assembly and the jet fitting on the nitrous spray nozzle is 24 inches. This
should also be considered when mounting the solenoid assembly.
2.6 Nitrous Spray Nozzle Installation
1. Determine nozzle mounting location in intake boot, between the MAF sensor and the throttle body. Make sure
the nozzle, mounting collar, and the feed line from solenoid to nozzle, do not interfere with any systems or
components of the vehicle such as the hood
latching device.
2. Mark where the nozzle will be placed.
3. Remove the intake boot.
4. Drill a 7/16” hole in the intake boot where nozzle
placement was determined.
5. Be sure to clean out the rubber shavings you
made when drilling to prevent engine damage.
6. Install nozzle mounting nut and collar onto intake
boot.
7. Using liquid Teflon, install the spray nozzle into
mounting collar.
8. Mark the spray direction on the nozzle. Be sure the
nozzle discharge is towards the vehicle’s engine.
9. Install the .039 jet into the nozzle fitting.
10. Install 3AN line from solenoid outlet fitting to spray
nozzle jet fitting and tighten securely.
11. Install the intake boot.
Nozzle
To Throttle Body
From Airbox
Nozzle should be placed in the intake boot so as
to have a clear path to the throttle body. Try to
keep the nozzle from having to travel through the
bend in the intake boot and as close to the
throttle body as possible.
