DESCRIPTION:

This kit is intended to enable you to upgrade your Performer Nitrous System to all of the Performer RPM

components and increase the horsepower gain to the RPM levels. Included in this kit is everything you will need to take
your current Performer level nitrous system and upgrade to the Performer RPM level system without having to purchase
a complete kit.

Component Installation

1. First, you will need to remove the Performer plate, gaskets, lines from solenoids to plate, and solenoid mounting

brackets that you had previously installed with your Performer Nitrous System. When you remove your old Performer
Nitrous Plate, be sure you remove all of the gasket material with it.

2. Install your new

Performer RPM Nitrous Plate (Item A)

onto the carburetor pad using the

2 supplied gaskets

(Items B)

with this system.

When installing fittings into the solenoids only use Teflon Paste.

Do Not Use Teflon Tape

. Teflon tape can break free

inside of the fittings and travel through the system and end up clogging your nitrous or fuel jets or solenoids causing
sever engine damage.

3. Hold the Performer RPM Nitrous Solenoid

(Item C)

securely, such as in a bench vise, being careful not to harm the

solenoid or block the inlet or outlet of the solenoid.

4. Install the 4AN X ¼”NPT N2O Filter Fitting

(Item J)

into the inlet port of your Performer RPM Nitrous Solenoid using

Teflon Paste.

5. Install the 4AN X 1/8”NPT Straight Blue Nitrous Fitting

(Item M)

into the outlet port of your Performer RPM Nitrous

Solenoid using Teflon Paste.

6. Install 1 of the 1-Up Solenoid Brackets

(Item E)

using two of the Solenoid Mounting Screws

(Item F)

onto your

Performer RPM Nitrous Solenoid and mount the solenoid in the same location as where you had your Performer Nitrous
Solenoid mounted.

7. Install the 12 inch Steel Braided Nitrous Line

(Item H)

from the outlet fitting of your Performer RPM Nitrous Solenoid.

8. Once you have made your jetting selection from the next page, install the appropriate nitrous jet into the plate fitting

and install the remaining side of your 12 inch Steel Braided Nitrous Line onto the nitrous fitting of the Performer RPM
Plate with the jet

(Item I)

in place.

9.

Hold the Performer RPM Fuel Solenoid

(Item D)

securely using the same method you used with your nitrous solenoid. Install

the 6AN X ¼”NPT Red Fuel Fitting

(Item K)

into the inlet port of your Performer RPM Nitrous Solenoid Using Teflon Paste.

10. Install the 4AN X 1/8”NPT Straight Red Fuel Fitting

(Item L)

into the outlet port of your Performer RPM Fuel Fitting using Teflon

Paste.

11. Install the remaining 1-up Solenoid Bracket using the 2 remaining Solenoid Mounting Screws onto your Performer RPM Fuel

Solenoid and mount the solenoid where you had previously mounted your Performer Fuel Solenoid.

12. Install the 8 inch Steel Braided Fuel Line

(Item G)

from the outlet fitting of your Performer RPM Fuel Solenoid.

13. Install the corresponding fuel jet for the horsepower level you have selected into the inlet fitting on your Performer RPM Plate.
