Introduction:

The Stage 3™ Mustang System is designed to deliver precise amounts
of water-methanol in a wide range of operating conditions. This system
can deliver cooler combustion temperatures, lower intake air
temperatures, and 20-25 point octane gains over regular pump gas. It
utilizes the factory washer fluid tank. This does not defeat the original
purpose of the tank and makes for an easy, professional installation.

Naturally aspirated Mustangs will utilize the EFI sensor capability of the
controller for injection control, while Mustangs with forced induction of
any kind will use both boost and EFI data to control injection.

Installation- Mechanical

Step 1 Bulkhead Fitting Install

The factory windshield washer
reservoir is used as the
reservoir for your system.

• Drill 9/16” hole in desired
bulkhead location.

• Remove one nut from
bulkhead and turn the
remaining nut until it is at the
very end.

• Feed red tubing through the
drilled hole and up and out of
the top of the reservoir.

• Attach tubing to the bulkhead
on the side opposite the nut.

• Pull the tubing through the
bulkhead hole until the
bulkhead seats against the
inside of the reservoir.

• Apply E6000® sealant
(included) around bulkhead.

• Slide the nut you had
previously removed up onto
the tube and thread onto
bulkhead.

• While pulling firmly on the
red tubing, tighten the outer
nut using a 17mm socket
(only needs to be hand tight).
A ratchet is not needed.

• Once sealant has set, fill
reservoir with water and
check for leaks.

Factory washer tank from a 2007 GT shown with 9/16 hole drilled for

bulkhead fitting. See page 19 for details on mounting the optional

fluid level switch. Note that in some cases it will be easier to mount

the bulkhead fitting in the side of the tank so that the hose exits in

the direction of the pump.

© 2010, Snow Performance, Inc

Caution******

To avoid gravity feeding of fluid with rear mount reservoirs, it is essential
to use a check valve in-line between the reservoir and pump. Do not
operate your rear mount equipped vehicle without a check valve
installed.

Caution*******

Whenever the nozzle is mounted post-throttle plate, to avoid siphoning
fluid at idle, it is essential to use a solenoid upgrade inline between the
reservoir and pump.

Step 2 Pump Install

Mount the pump so the inlet is positioned at the lowest point of the
reservoir or lower. Pump can be mounted horizontally or vertically using
the supplied screws and washers. Ensure that no sharp bends in the
high pressure tube occur near the pump. Sharp bends can cause stress
on the inlet and outlet ports of the pump, causing leaks. Trim tube with a
utility knife or razor blade, making sure to eliminate any burrs or kinks on
the end. Insert firmly into the pump about ½ inch through the light grey
locking collar. Note the arrows indicating flow direction on the top of the
pump. To remove the hose, gently and evenly push the light grey locking
collar into the head unit of the pump, then pull on the hose gently.

Measure the distance from the bulkhead fitting on the reservoir to the
pump inlet. Cut the ¼” red tubing using utility knife. Make cuts are as
square as possible.

Ensure there are no kinks in the tubing and insert tubing into quick
disconnects at pump and reservoir until fully seated. Keep the pump
within 2 feet of the reservoir.

Caution******

Pump must be shielded from road debris and tire wash.
Failure to do so will result in pump failure

Step 3 Nozzle Selection

Nozzle sizing is a function of horsepower, which approximates the
engine airflow, and boost, which approximates intake charge heat. The
following are some general guidelines (assuming 50-50 water-methanol).

Engines running mild or high boost and making 400-600 HP will use a
375 ML/MN nozzle or 625 ML/MN nozzle. (Red and Blue colored nozzles
respectively)

Engines making mild boost and 200-400 HP will use a 175 ML/MN
nozzle or a 225 ML/MN nozzle.

A naturally aspirated engine making 300-400 HP will use a 100 ML/MN
nozzle or a 175 ML/MN nozzle.

A naturally aspirated engine making 400-600 HP will use a 225 ML/MN
nozzle or a 375 ML/MN nozzle.

Seal the nozzle into the nozzle holder using

included E6000® sealant. Using a sealant that is
not permanent will allow for nozzle changes during tuning. Simply
remove the nozzle, clean the threads, and reinstall using sealant.

Assemble desired nozzle into nozzle holder using E6000® sealant. The
end of the nozzle with the fine mesh screen is to be inserted into
the nozzle holder. Torque 1/2 turn past finger tight. Do not use Teflon

sealants on Snow Performance fittings.

Correct Incorrect

Step 4 Nozzle Mounting

The nozzle should be installed 90° to the direction of airflow. On round
intake tubes, this is 360° around the tube meaning the nozzle can be
mounted in any direction. This will ensure maximum cooling as the
nozzle sprays in a cone pattern. The nozzle should be the highest point
in the system, and its tip should be flush with the inside wall of the tube
or projecting slightly into the airflow to ensure good spray pattern.

Drill and tap (11/32" pre-drill, 1/8”-27 NPT tap) air inlet tube as close as
feasible to throttle body/throttle plate. Be sure to remove the pipe to
avoid getting any shavings into the engine.

© 2010, Snow Performance, Inc

Solenoid Upgrade (optional)

The optional Solenoid Upgrade (#40060) is required if the nozzle is to be
installed after the intake throttle plate (as shown), or the fluid reservoir is
mounted higher then the nozzle. It is highly recommended for trunk­mount reservoirs.

Finger thread the two 1/8” NPT quick connect fittings into ports labeled (2
or IN) and (1 or OUT) on the solenoid. Tighten an additional half turn
past finger tight.

Note: Solenoid must be installed Pre-pump to ensure
correct operation.

Cut high pressure line at location solenoid is to be installed. Insert ends
of cut line into quick connect fittings of solenoid. The port labeled (2 or
IN) is the inlet and the port labeled (1 or OUT) is the outlet. Gently pull
on line to check secure connection. If line pulls out, re-insert farther into
fitting to engage locking clips. If high pressure line removal is required,
firmly press in metal fitting ring to disengage locking clips while pulling
hose from fitting.

Connect one of the BLACK wires from solenoid to the RED positive
pump wire or the WHITE wire from the controller. Note that connecting
the wire to any other power source other then the pump/controller wire
will result in improper operation of solenoid. Connect the second BLACK
wire to a secure chassis ground location.

Fluid Level Switch

Fluid level switch and Bulkhead fitting shown on ’07 Mustang Washer Bottle.

Instructions

• Locate desired level switch mounting position. Suggested
placement is 1/5 of max reservoir height.

• Carefully drill side of reservoir using 13/16” bit. A step bit is
recommended for best drilling results. Hole
must be free of nicks or shavings for proper
sealing.

• Remove rubber seal from level switch.
Insert seal into reservoir until fully seated.
Goop can be used around the edges of the
hole.

• Lubricate exterior of level switch with water
and insert into seal until fully seated. Position level switch so GT
symbol is at six o’clock position.

• Wait 30 minutes for Goop to cure, then test for leaks. With fluid
level above level switch, float should be angled up. With fluid
level below level switch, float should be in horizontal position.

• Connect one black wire from level switch to ground.

• Connect other black wire from level switch to white wire from

LED.

• Connect red wire from LED to +12 volt key on power source.

Intake tube from Shelby GT shown. Note that the nozzle mount
adaptor (part number 40100) may be useful for stock plastic intake
pipes.

The nozzle is mounted using its external 1/8 NPT threads. Tighten the
nozzle and nozzle holder assembly one half turn past finger tight using
E6000® sealant to seal the threads.

The recommended nozzle mounting point is before

the throttle body/plate and above the level of the
reservoir. If you mount the nozzle after the throttle body/plate or
below the reservoir, a Solenoid Upgrade (#40060) must be used to
prevent siphoning at idle or gravity feed.

© 2010, Snow Performance, Inc

Step 5 Nozzle Connection

Measure the distance from the pump outlet to the nozzle holder(s). Cut
the ¼” tubing using a sharp utility knife or razor blade. Make cuts as
square as possible.

Ensure there are no kinks in the tubing and insert tubing into quick
disconnects until fully seated. Gently pull on tubing to ensure a good
connection. Also ensure that engine movement will not stress the tubing
or fittings.

Use tie wraps to help route tubing and to ensure it doesn't contact
moving or hot parts in the engine compartment. Have tubing connect to
quick connect fittings at shallow angles. Having an immediate sharp
bend may unseat the tubing from the internal o-ring and create a leak.

Continual insertion and removal from quick connect fittings will mar the
end of the tubing. Over time the internal gripping teeth may lose their
hold of the tubing which may create a leak. If this occurs simply remove
the tubing and make a fresh cut using a razor blade.

Variable Controller Installation

© 2010, Snow Performance, Inc

For best performance, cooling and system life it is recommend that
Snow Performance Boost Juice™, part #40008, be the exclusive
fluid used in the system.

• The Pump should be off at this point. Start the vehicle and apply
pressure to the boost line with a hand pump. A few psig will be
sufficient to start injection. The controller should display an injection
% and a boost reading should also be visible (if you are in the proper
display screen).

• Ensure that the Blue leads are connected to a fuel injector harness.
Unit will show a PW value and also an injection % if you are in the
correct display mode with the vehicle idling. If no PW or injection is
indicated, check the connections to the fuel injector harness.

Tuning Quick Reference

The power potential of the system is realized through increased
boost and/or timing. The large gains on octane and cooling
provided by the system make this possible, even on standard pump
fuel.

The Boost Cooler® adds an alternate fuel source as well as
significantly cools combustion. With the Boost Cooler®, one does
not need to cool combustion with overly rich air/fuel ratios. To
minimize combustion quench, you should start with an air to fuel
ratio of 12.0-12.5:1.

Injecting water/methanol lower than 3300-3500 RPM could result in
combustion quench. All vehicles are different. If the engine bogs or
loses power, then it is coming on too early, the quantity is too
much, or there is not enough methanol in the mixture (50/50
water/methanol recommended).

Caution******

Prolonged quench may cause lower engine damage over a period of
time.

Maintenance –

Remove nozzle(s) and clean screen filters at

least once per year using carb cleaner.

The Boost Cooler® has been designed to operate with high
concentrations of methanol. Oil or other additives are not required
for system lubrication.

The Stage 3 controller has an integrated wiring harness for ease of
install and a clean appearance. Refer to the main wiring diagram and
listing below for installation.

CAUTION: Disconnect the negative battery terminal while

connecting wires to prevent electrical fire or damage to controller.

• Connect BLACK wire to a good ground location.

• Tie GREEN wire out of the way.

• Connect RED wire to a 12 volt key on source.

• Connect the two BLUE wires to the two wires leading to a fuel

injector using the provided wire splices. Any injector will suffice, so
choose one that is easy to access. Note: Do not solder electrical
connections to the fuel injector. Use provided wire splices.

• Connect the clear tubing to the black silicone line. This line can be
‘T’ed into any accurate manifold boost pressure source. A boost
gauge line that is tapped into the intake manifold is ideal. In naturally
aspirated applications, this can simply be tied out of the way.

• Connect the WHITE wire to the red power wire of the pump. The
BLACK wire on the pump goes to a good chassis ground.

Always have a good electrical ground connection.

Poor ground will result in erratic operation of
controller and/or damage to the controller. Make
sure boost connection is POST throttle body.

Tuning the Stage 3 System

The Stage 3 system allows for a large range of tuning on any EFI or
forced induction Mustang. It can reference fuel injector pulse-width,
boost, or both simultaneously. The boost and EFI data are displayed on
the LCD screen, along with the systems output as a percentage of pump
capability.

All functions of the controller are accessed using the two push buttons to
the left and right of the LCD screen. Pressing button 1 will scroll between

© 2010, Snow Performance, Inc

screens, while pressing button 2 will affect whatever setting is on the
screen.

Display and Control Screens:

Screen 1
This is a display only screen. It displays boost, fuel injector pulse-width
(PW), and water/methanol injection as independent bar graphs.

Screen 2
This display screen shows boost in psi and injector pulse-width (PW) as
a percentage. 100% pulse-width indicated 100% injector duty cycle and
a fuel system injecting as much as possible

Screen 3
This screen displays boost in psi, while pulse-width (PW) and injection
are shown as a percentage.

Screen 4
This screen displays boost in psi and pulse-width (PW) as a percentage.

Screen 5
This is the first setup screen. It allows you to select BOOST, EFI, or
BOTH, using button number two. If BOOST is selected, then boost alone
will determine the injection volume from the nozzle. If EFI is selected,
then fuel injector pulse-width (PW) alone will determine injection volume.
If BOTH is selected then both inputs will be used simultaneously to
control injection.

• Fill reservoir with water approx ¼ full.

• Remove tubing from nozzle (or solenoid if solenoid used in-line

between pump and nozzle) and run tube into separate container.

• Apply 12 VDC to red pump wire for approximately 5 seconds or
until fluid flow is consistent.

• Pump is now primed. Reconnect tubing from pump outlet to
nozzle (or solenoid).

If using a check valve in between the pump and the reservoir:
Remove the check valve and place a solid piece of tube between the
pump and the reservoir and prime the system. Then replace the check
valve in between the pump and reservoir.

Step 1 Test Pump and Mechanical System

Disconnect all control and SafeInjection® modules. Disconnect tube from
the outlet port of the pump. Using a 12 volt source, apply power to red
wire of pump. Pump should activate and fluid level in tank should go
down. It is recommended to also check the nozzle spray pattern while
following this procedure. Also check for leaks. Do not pump fluid through
a SafeInjection® module without all nozzles connected. This can
overflow the unit and cause damage.

If pump goes on and fluid level doesn't go down, there is an obstruction
in the tube or nozzle. Activation of the pump in 1-5 second intervals will
purge air from the system after installation. This can be accomplished
during initial use.

Step 2 Test Controller

• Turn ignition key on so that the system has 12volt power. If the
pump runs, inspect ground wires for secure connection and repair as
needed.

• Set the controller to inject at 1 psig of boost, and to start injection at
1% PW.

© 2010, Snow Performance, Inc

Boost Start: 4 psig
Boost Full: 15 psig
EFI Start: 25%
EFI Full: 65%
PW/BOOST 65/35

Under moderately heavy throttle, boost will trigger a small amount of
injection for cooling and efficiency. As more boost builds under higher
throttle positions, the system will add more injection. In the event that
boost reaches higher levels (such as in a race or in a WOT situation on
the street) the system will inject very aggressively for maximum octane
gain and cooling. But because EFI data will provide a more gradual
injection curve (boost comes on instantly) the EFI values are weighted
more heavily. This makes for a more progressive curve.

Note that in all of the above examples, all of the data needed in terms of
PW and boost can be obtained through the controller display itself.
Simply driving under cruising conditions and trying various levels of
throttle and boost will allow the user to determine good set points for
injection.

Other controller features:

The controller can be put into a “read-only mode” for the purpose of
viewing boost and EFI data without injection. To toggle this mode on and
off, press and hold button 2 in any display screen. While holding button 2
down, press and hold button 1. After 1 second, release both buttons. The
controller will give no indication that it is in read only mode except for the
fact that it will not inject under any circumstances.

The controller also has the ability to be programmed and display
data in standard or metric units. Holding down button two while
powering up the unit will trigger metric units. Pressing and holding
button one as power is first applied will select standard units.

Testing the System

Note: for best results, prime pump before use

PW/BOOST CONTROL INC
This screen adjusts the balance between boost and PW based injection.
Pressing button 2 will increase the PW importance and decrease the
boost importance by 1%. If it is set at 50/50, then PW and boost are
weighted equally to determine how much to inject at any given time. The
weighting can be adjusted in 1% increments. 50/50 is often a good
starting point.

Screen 8B
PW/BOOST CONTROL DEC
This screen will decrease the importance of PW while increasing the
importance of boost in 1% increments as you press button 2. Decreasing
the weight of boost is useful for quick spooling turbos or positive
displacement superchargers in EFI applications. (See Screen 8A)

Control injection through the EFI function. This application idles at about
3% PW, cruises on level ground at 65 MPH at 15% PW, and will climb to
70% PW at WOT and peak RPMs:

Injection Mode: EFI
EFI Start: 20%
EFI Full: 60%

Anytime any moderate throttle is applied, the system provides a small
amount of injection. As more throttle is applied and PW increases, the
system provides progressively more injection.

Moderate Boost EFI Application:
This car makes a peak boost of 12 psig with a Procharger, and at idle
has 5% PW, 65 MPH cruise is about 18%PW, and at WOT and peak
RPMs 85% PW:

Injection Modes: ‘BOTH’
EFI Start: 40%
EFI Full: 60%
Boost Start: 3 psig
Boost Full: 11psig
PW/BOOST 50/50

Here we are using both boost and PW to control injection. Procharger’s
have a smooth boost ramp that makes for a progressive injection curve.
So we weight boost and EFI equally on screen 8. As boost and EFI PW
go above normal cruising conditions, we get a small amount of injection.
In the event that high levels of throttle are used and boost goes to 9PSI,
the system will inject at full capacity.

Positive Displacement Blower Application:

This is a Whipple blower making about 15 psig. The blower makes
around 3 psig even in moderate throttle situations, and can hit 15 psig
almost instantly.

Injection Mode: ‘Both’
