Congratulations! You have purchased the finest street supercharger available for the Mustang Cobra. The centerpiece of this kit is the High Efficiency PAXTON Supercharger, a mechanically driven centrifugal blower.

This kit comes with all the parts you will need to install the supercharger. The instruction manual has been edited in order of sequence, and photographs and drawings have been included to illustrate the text. This will allow you quick part identification and orientation.

The installation will require metric and SAE sockets and wrenches, a hand drill and bits, an Air Hammer (and compressor), a 3/8” x 18 NPT tap, screwdrivers, and a supply of buckets for the reserve of coolant and oils.

We suggest that you obtain a copy of a Mustang shop manual for your model of car. This may be obtained from your dealer, or may be ordered by mail from Helm Publications at (800) 782-4356. Become familiar with the details of your car’s system. If it is not operating within normal parameters, we do not recommend the installation or use of the supercharger.

For the quickest installation time, we suggest that you read this manual thoroughly before beginning. Make sure that you understand the process, have identified the areas of the car that you will be working on, and have the tools that you will need on hand. The average installation time is 8 to 10 hours, but your time will depend on your working conditions, experience installing superchargers, personal skill level, and preparedness for the job. This estimate does not include time for the initial vehicle inspection, cleaning, fine tuning, or troubleshooting. Once again, we recommend reading the manual before beginning the process. We are available for tech support at (805) 604-1336, Monday through Friday, 7AM - 3 PM PST.

After reading the manual, verify that all major assembly groups are present in the main kit box. As you remove a box or bag, note the identification label and compare it to the parts list.

PAXTON AUTOMOTIVE makes every effort to insure that all parts

are included in the box. If you discover that you are

missing any part, or that a part was damaged in shipping,

call PAXTON immediately. DO NOT begin installation if a part is missing.

Failure to contact PAXTON prior to beginning installation

will result in a charge for the missing part.

We suggest that the engine compartment be cleaned before the installation. You can clean the engine with a pressure washer that is found at self-serve car washes. Use a safe-for-aluminum cleaner/degreaser, and cover the distributor and any electronics with a plastic bag to prevent water from entering.

Introduction

You are undoubtedly eager to get started, but please take a little more time to insure that your safety is not in jeopardy. A moment’s lack of attention may cause a serious injury to you, or to someone else who happens to be standing around. By following some simple safety precautions, you can avoid many potential dangers. The following list is not meant to be a comprehensive list, but rather it is meant to make you aware of some of the risks, and encourage you to take a safety minded approach to your work area.

Never rely solely on a floor jack when

working underneath a vehicle. Always

use jack stands that are rated for the

weight of your vehicle, use them at the

recommended lift points, and place your

vehicle in ‘PARK’ or ‘FIRST’ gear with the

parking brake set.

Always use eye protection when using power

tools, such as drills, saws, and grinders, or

when working underneath a vehicle.

Never smoke, use an open flame, or have spark

producing items around gasoline or flammable

objects. Always have a fire extinguisher that

is rated for chemical and electrical fires handy

when working on motor vehicles. Also, make sure

that the extinguisher is fully charged.

Operate engines only in a well ventilated area. Carbon

Monoxide, gasoline, and solvent vapors

are colorless and sometimes odorless, and

may asphyxiate or explode without

warning.

Always disconnect the battery from

your engine before doing work on the electrical

or fuel systems, or doing underdash work.

The chemicals used in the vehicle systems,

such as oils and coolants, are poisonous. Clean

up any spills immediately, and dispose of

waste materials properly. Pets, wild animals, and

children may die if they ingest the liquid.

PAXTON Automotive thanks you for your purchase. We welcome your comments and suggestions to help us improve our product.

DISASSEMBLY-- Preparing your vehicle.

NOTE: Beware of coolant spills. Mop up any spilled coolant

immediately. Radiator coolant very attractive to animals,

and highly poisonous.

1. Drain approximately one gallon of coolant from the radiator and disconnect the negative side of the battery. Disconnect the MAF sensor, air inlet temp sensor and air idle bypass hose from the air inlet tube, then remove the inlet tube and air filter housing by removing the single 8mm bolt. (Fig. 1. Fig 2)

2. Remove the coolant reservoir, upper radiator hose and disconnect the lower hose from the coolant transfer manifold (CTM). Remove the spark plug wire retainer atop the alternator, followed by the stud and nut arrangement that holds the CTM in place. Unplug the two sensors, and remove the CTM (it is press-fit and sealed with O-rings, so it will take some wiggling to get it free). (Fig 3, Fig 4)

20. Relocate the spark plug wire retainer by drilling a 17/64-inch hole across from an existing hole in the bracket (Fig 29, arrow), and move the bracket forward. It will now be secured by only two factory bolts. Fig 30 shows the completed spark plug wire retaining bracket in place.

21. To provide clearance for the washer bottle, modify the driver’s side radiator support bracket by cutting a notch in it as shown in Fig 31

22. Relocate the coolant reservoir by widening the notches in the plastic cover and installing the Paxton-supplied aluminum relocation tabs using the stock hardware.(Fig 31, arrows) This will move the reservoir over one inch towards the driver’s side. Install the thick round spacers on the recut reservoir bracket. Reinstall the reservoir using the stock nut on the rear notch and the supplied hardware on the front notches.

23. From under the vehicle, remove the two 8mm head bolts securing the coolant reservoir support rod. Relocate the support rod by moving it one bolt hole towards the driver’s side and secure with the original bolt. Using a 1/4” drill bit, drill through the remaining mounting hole and secure with the supplied nut, bolt and washers. (FIG 32) You can gain access to the hole through a slot in the body sheet metal directly above the hole you drilled.Slide the 3/8” thick round aluminum spacer onto the threaded portion of the support rod.

OIL SYSTEM MODIFICATIONS

The Novi 2000RR supercharger relies on pressurized engine oil for its lubrication. The following steps show how to install the oil feed and drain lines. NOTE: Do not attempt this step with a hammer and punch, as you will severely dent the front of the pan.

24. Mark the front of the engine oil pan 1-1/8 inch below the pan rail and between the two pan rail bolts, directly in the center of the small ‘hump’. Drill a pilot hole with a 3/16-inch drill bit after smearing the drill bit with heavy grease to prevent small metal particles from falling into the pan. (Fig 33)

Once the hole has been drilled, insert a straight length of welding rod or heavy wire (such as a coat hanger) into the hole approximately three inches to see if it contacts any of the reciprocating assembly (connecting rod, crankshaft counterweight). If it does, turn the engine over and repeat the process until no interference is encountered.

Next, apply a small amount of anti-seize lubricant to the tip of the punch (Fig 34), and insert it into the pilot hole. Hit the punch with an air hammer carefully using small bursts, until the punch is inserted up to its shoulder. NOTE: Use extreme caution not to make the hole too big, or the drain fitting will not fit and the pan will be ruined.

25. Apply a liberal amount of heavy grease to a 3/8-inch by 18 NPT tap (not included), and gradually thread into the hole. NOTE: Only run

the tap 2/3 of the way in. Otherwise the fitting will not seal properly. Clean the threads

using a clean rag and an approved solvent, such as carburetor cleaner. Apply a small amount of silicone RTV to the threads of the supplied 3/8-inch pipe to -8 fitting and insert into the hole, being careful not to over-tighten.

The hex nut of the fitting should be clear of the pan, leaving some thread showing. Install the supercharger drain hose fitting so that

the elbow is oriented toward the passenger side, away from the harmonic dampener, (Fig 35)

26. The supercharger feed line is attached by removing an existing pipe plug in the bottom of the oil filter housing, and installing the supplied ⁄-inch NPT to –4 90-degree fitting and steel braided hose (Fig 36, arrow). Run the line up the side of the engine, between the valve cover and the power steering reservoir bracket, under the coolant transfer manifold and attach it to the supercharger.(Fig 37) Zip tie the oil feed line to the CTM.
