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, experi-
ence installing superchargers, personal skill level, and preparedness for the job. This esti-
mate does not include time for the initial vehicle inspection, cleaning, fine tuning, or trouble-
shooting. Once again, we recommend reading the manual before beginning the process.
We are available for tech support at [phone], 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-alu-
minum 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 pre-
cautions, you can avoid many potential dangers. The following list is not meant to be a com-
prehensive 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 sug-
gestions 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, fol-
lowed 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)

7. Remove the water pump pulley, followed by the idler pulley (Fig 11), which will be re-
installed in a later step.
8. Remove the four 18 mm bolts at the front of the engine (marked with arrows in FIG 12).
Replace the bolt in the water pump with the supplied bolt and small diameter washer.
Replace the topmost bolt with the supplied low profile bolt. The remaining holes will be used
as attachment points for the idler support bracket in step 10.
PREPARING TO INSTALL THE SUPERCHARGER
9. Use a tubing bender to bend the metal A/C line. It is first bent upwards, then rotated down-
ward to clear the bottom portion of the supercharger. (Fig 13) NOTE: Use extreme caution
during this step. The refrigerant contained within this line is under high pressure and can
cause injury if the line ruptures. Use a tubing bender such as the one shown, as well as safe-
ty glasses/goggles. Gloves are also recommended.
10. Install the idler support bracket using the holes from step 8. It serves as a support for the
main supercharger bracket and mounting point for the supplied idler pulley. (Fig 14)

11. Remove the 13 mm stud bolt that is located under the lower corner of the passenger side
valve cover. This bolt stud supports the metal A/C line through the use of a small tab. Enlarge
the hole in the tab to 5/16-inch to accommodate the larger fastening hardware for the rear
supercharger support bracket. (Fig 15)
12. Install the rear supercharger mounting bracket in the three holes left by the coil mounting
bracket. The bolt/spacer assembly (arrow) bolts into the hole left by the 13 mm bolt stud, and
‘sandwiches’ the A/C line tab in place between the head and spacer. (Fig 16)
13. Mount the supplied idler pulley on the idler support bracket using the supplied hardware.
Trial fit the idler pulley first; if it does not fit, one of the ribs on the alternator must be ground
off (Fig 17). When the pulley clears the alternator it can be bolted into place. Install the stock
idler pulley in its original location, followed by the water pump pulley using the factory hard-
ware. (Fig 18)

COOLING SYSTEM MODIFICATIONS
These modifications are necessary in order to allow clearance for the supercharger.
18. The supplied Coolant Transfer Manifold
(CTM) is taller than the original, providing nec-
essary clearance for the supercharger. To
mount the new CTM (Fig 24), trim the 6mm
portion of the two mounting stud bolts to 3/4
inch, and thread the supplied aluminum spacer
stands (Fig 25,arrows) into place to properly
locate the CTM. Remove the original coolant
temperature sensors from the old CTM and
install in the new unit. Install the CTM and
secure with the supplied fasteners. (Fig 26)

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”

OIL SYSTEM MODIFICATIONS
The Novi 2000RR supercharger relies on pressurized engine oil for its lubrication. The follow-
ing 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 recipro-
cating 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 fit-
ting 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.
SMOG PUMP/INTAKE SYSTEM MODIFICATIONS
These steps illustrate how to relocate the smog pump and install the new intake system
27. Unbolt the smog pump and ignition module
from the passenger side fenderwell. Bolt the
smog pump and the module to the new bracket
using the supplied screws for the module and
factory bolts with supplied nuts for the smog
pump. The plug on the module should point
straight up. Connect the plug to the module
and bolt the assembly to the original mounting
point using the supplied bolts and spacers between the bracket and the body. APPENDIX I,
