DESCRIPTION: The concealed nitrous kit is a kit designed to be concealed in the vehicles as well as quickly and easily installed and
removed. This kit provides a minimal nitrous gain, but enough to get those extra hundredths of a second off of your elapsed time.
INSTALLATION INSTRUCTIONS
ATTENTION: Two 9-volt batteries are required for this kit (not included).
WARNING: ONLY USE LIQUID TEFLON PIPE SEALANT ON THREADS. USE OF TEFLON TAPE CAN CAUSE DAMAGE TO YOUR
SYSTEM AS WELL AS THE ENGINE DUE TO TAPE DEBRIS COMING LOOSE AND FLOWING THROUGH YOUR SYSTEM.
1. Connect the solenoid assembly to the bottle valve outlet fitting. Do not use any thread sealant.
2. Place one end of the polyline into the compresssion fitting coming off of the Performer solenoid tee and tighten the
compression fitting securely. The polyline should not be able to be pulled out of the compression fitting if this is done right.
Install the other end through the B-Nut, through the cone ferrule, and into the selected jet. Tighten securely so the cone
ferrule pinches around the edges of the polyline and cannot be pulled out.
Do not use any sealant on the compression
fitting.
3. Install the vacuum lines and hose clamps from the nitrous pressure regulator to the nitrous vacuum tee as shown in the
diagram pictured below. Make sure the jet in the vacuum tee is a .080” jet. Be sure the tee end with the jet is attached to
the hose leading to the fuel pressure regulator.
4. Intersect the nitrous vacuum tee in the vacuum line leading to the fuel pressure regulator.
5. Connect the wiring as shown in the diagram below.
