NOTICES

(Read before installation is started)

Included in this kit is a smaller than originally supplied supercharger pulley. This new pulley is recommended to achieve the best performance results. Removal of the factory sealed pulley will reduce the supercharger warranty from three years to one year unless the supercharger unit (with the original pulley still attached) and new pulley are sent into Vortech for removal, installation and re-sealing. If the supercharger warranty is not a concern or if the supercharger warranty has expired, the pulley may simply be removed and replaced with the new part supplied. Hammering/prying etc. on the supercharger and/or pulley will cause damage to the parts. Light heating of the supercharger pulley with a propane torch (if the pulley is tight on the shaft) will aid removal. A return authorization number is required before the supercharger and pulley are sent into Vortech. Call the Vortech service department at (805) 247-0226 for a return authorization number. Return freight (ground) will be paid by Vortech.

Installation Instructions

1999 Ford 4.6 Mustang Cobra (4 Valve)

Before beginning this installation,

please read through this entire instruction booklet

The Vortech Maxflow Power Cooler system was designed as a street/strip oriented aftercooler, specifically for use on 1999 Ford 4.6 Mustang Cobra vehicles equipped with a Vortech supercharger producing up to approximately 580 horsepower.

As with any power enhancing product, this system is intended for use on healthy, well-maintained engines. Vortech Engineering is not responsible for engine dam- age. Installation on new vehicles will not harm or adversely affect the break-in period so long as factory break-in procedures are followed.

For best performance and continued durability, please take a note of the following key points:

1. Use only premium grade fuel 92 octane or higher (R+M/2).

2. Always listen for any sign of detonation (pinging) and discontinue hard use (no boost)

until problem is resolved.

IMPORTANT: If the vehicle still has the battery located in the factory position, it

must be relocated into the trunk to make room for the water tank assembly. Vortech part number 8N150-010 is a Heavy-Duty Battery Relocation Kit that may be purchased separately. Commonly available “universal” relocation kits may be used but they will most likely contain a smaller cable. Additional fabrication may also be necessary when using a “universal” kit.

A. Remove the air dam from the lower radiator

core support.

B. Loosely attach the supplied water cooler brackets

to the cooler using the supplied 1/4” hardware (see Fig. 6-b). Following the photo, position the cooler on the core support as far towards the passenger side as possible. Using the mounted cooler brackets as a guide, mark the position on the lower radiator core support where the bracket mounting holes must be drilled (see Fig. 6-a). Drill the four mounting holes and attach the cooler assembly to the core support with #12 hardware.

C. Notch the air dam to allow clearance for the cooler

mounting brackets and reinstall.

D. Route the previously attached 50” section of hose

extending downward from the lower 90° fitting on the water tank to the inlet of the water pump. Secure hose with nylon ratchet clamps.

E. Secure the hoses to the chassis with provided tie

wraps.

F. Cut a piece of the 3/4” hose 42” in length and

attach to the outlet fitting of the water cooler. Connect hose to the inlet fitting on the aftercooler. The line should run parallel with the return line. Trim the ends appropriately and secure both with nylon ratchet clamps.

G. Following photos 9 and 10, attach the supplied

rubber 90° hose bend to the water cooler inlet. Slide the water pump bracket onto the water pump and position the outlet of the pump in line with the 90° hose bend. Using the bracket as a guide, mark and drill holes in core support and attach with the supplied hardware. Trim the 90° hose if necessary, and secure with nylon ratchet clamps.

NOTE: Hoses must not be kinked or restricted.

Route away from moving parts and direct engine heat.

7. Water Pump Wiring

A. Cut the supplied wiring harness plug from the end

at the water pump harness. Attach a 16 GA eyelet to the black wire (negative) and route to a clean ground free from paint and vehicle undercoating. A cooler mounting tab works well for this.

B. Route the red wire from the water pump through

the firewall to the fuse panel. Connect to fuse #18 using the supplied fuse tap, fuse and fuse holder (make sure that the supplied secondary fuse is spliced into the power wire). Secure the red wire to the chassis using the provided tie wraps. Connect the red wire using a solderless connector to the positive wire on the wiring harness of the water pump.

C. Fill the water tank with 25% antifreeze and 75%

water to approximately 3” from the top. Do not fill past the water return fitting (doing so will not allow system to purge itself of air).

D. Turn the ignition key to the “ON” position and

check that the water is flowing through the system. Once water is flowing, allow to run for approximately one minute. This will allow any trapped air to be purged from the system. Once all the air is removed, fill the tank to one inch below the filler ring.

NOTE: Do not attach the red wire to the power

until the water tank is full of water, running the water pump without water will lead to premature failure and void your warranty.

NOTE: In some cases, the water pump must be

primed on initial start-up. This may be accomplished by turning on the pump, removing the RETURN line from the tank and providing light suction on the hose to remove the air in the system.

8. FMU Recalibration

A. Remove the six (6) allen head screws on top of

the fuel management unit (FMU).

B. Remove the diaphragm and washer (and the ring,

if equipped) from inside of the FMU.

C. Remove the four screws holding the valve body.

Once taken apart, remove the piston, small diaphragm, disk and O-ring.

D. Remove and exchange fittings on the valve body.

A small amount of Teflon sealant (not silicone or RTV) may be used on the fittings. Excessive sealant may damage the FMU.

E. Install the new O-ring, disk and small diaphragm

as shown. The disk must be centered on the valve body. The disk should not be allowed to make contact with the screws as this can damage it, resulting in FMU leakage and/or malfunction.

F. Before tightening the valve bodyscrews, install the

piston with the radius side down. Apply a small amount of pressure on the piston to eliminate any possibility of an air bubble being trapped between the disk and diaphragm.

G. Tighten the four screws to 24in/lbs (2ft/lbs) in a

crisscross pattern to ensure a proper seal.

H. Install the replacement ring (with the notched part

facing down) around the four screws inside the FMU.

I. Place the new washer inside the ring on top of the

piston.

J. Install the new diaphragm and carefully line up

holes to the body.

K. Reinstall the FMU cover with the six (6) allen head

screws. DO NOT OVERTIGHTEN THE SCREWS. The correct torque is 24in/lbs (2ft/lbs).

NOTE: If you are unsure of your ability to correctly

complete these steps, please contact Vortech Engineering at (805)247-0226 and ask for the Service Department.

NOTE: Ignore this section if the kit is being origi-

nally installed into the vehicle with the supercharger kit at the same time.
