Introduction
This kit progressively injects water-methanol according to manifold boost
pressure. The system is applicable for turbo diesels making over 25 psig
of boost pressure. The controller utilizes a heavy-duty design that can
read up to 100 psig of boost. It has two dials to set the start and full
points to tailor the delivery to your engine’s needs. Progressively
injecting according to boost pressure allows for the most power over the
widest range of RPMs. These kits allow for great horsepower increases
and EGT reductions – expect about 70hp and 250° F EGT drop using
50% water/methanol fluid. Please refer to system diagram during install.
Tech Tip: The provided arming switch is used on the controller power
supply. The prong with the piece of plastic coming out with it connects to
12VDC key on power, the other prong connects to the RED wire on the
controller.
Tech Tip: The system can use two nozzles simultaneously, but this is
not always needed. Refer to the nozzle guide on page 8 for nozzle
selection.
. Note that in many cases only one nozzle is needed (see page 8).
Installation – Mechanical
Step 1 3qt Reservoir Install
Install straight fitting with E6000® sealant and mount reservoir as high in
engine compartment as possible using #8x1½” sheet metal screws and
washers provided. Note that the nozzle should be the highest point in the
system, not the reservoir.
Optional: The factory windshield washer reservoir can be 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 a liberal amount of 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.
Bulkhead Fitting Installed in Washer Tank.
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.
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. 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 reservoir outlet 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.
Nozzle Identification Chart:
Nozzle
Number Nozzle Size
Nozzle
Number Nozzle Size
1 60 ml/min 4 225 ml/min
2 100 ml/min 5 375 ml/min
3 175 ml/min 6 625 ml/min
Recommended starting points:
250 - 400 WHP 625 ml/min nozzle
425 – 525 WHP 375 & 625 ml/min nozzle
550 - 650 WHP 2 X 625 ml/min nozzle
Seal the nozzle into the nozzle holder using
included GOOP® 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 assembly should be installed 90° to the direction of airflow.
On the 5.9l the preferred location is the back of the air horn (see photo).
Choose and mark mounting location . Remove the air horn and drill and
tap (11/32" pre-drill, 1/8”-27 NPT tap) for one or two nozzles.
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 tip of the nozzle should be
either flush with the inside wall of the tube or protruding slightly from it to
ensure proper spray pattern.
Tech Tip: Shallow mounting of nozzle could result in spray coalescing
resulting in reduced performance.
Addendum for 6.7L Cummins Applications:
Nozzles are mounted in the black plastic tube that connects the
intercooler-to-intake located on the driver’s side of the engine.
Step 1.
loosen clamps that attach tube to cast elbow and intercooler.
Step 2.
Pry rubber boots off intercooler and cast piece.
Step 3.
Slide tube out from top and mark, drill and tap for nozzles.
Tip: Mount nozzles approx 3” apart so spray is 90º to airflow.
Tip: To make sure there is no pooling of fluid while injecting,
make sure nozzle tip is at least flush with the inside of the tube
when tightened.
Step 5 Nozzle Connection
Measure the distance from the pump outlet to the nozzle holder. Cut the
¼” 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 until fully seated. Gently pull on tubing to ensure a good
connection.
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.
Tech Tip: Continual insertion and removal from quick connect fittings will
mar the end 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
The figure above shows the back view of the variable controller. Attach
controller to secure location with easy access in engine bay or
passenger compartment. The VC series controllers are designed to
withstand engine bay conditions, but should not be mounted directly to
the engine block or road spray. Connect vacuum/boost hose from intake
plenum boost line (use the included boost ‘T’) to hose barb on back of
controller and secure with a tie wrap.
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.
• Connect GREEN wire to Pump RED power wire. Connect green LED
per wiring diagram.
• Connect RED wire to inline switch and connect to +12V key on
source.
4 3 2 1
• When selecting a 12 volt key on source, try to find a dedicated circuit
fused for 15+ amps. Mount arming switch in driver’s compartment.
Always have a good electrical ground connectionideally battery neg. Poor ground will result in
erratic operation of controller.
Variable Controller
Tuning
• Use a tie wrap to keep rubber vacuum/boost line on hose barb in
high boost applications.
• Adjust the “Start Psi” boost level first by turning dial clockwise to
about one third of the engines max boost output. This sets the boost
pressure required to activate the injection system. Typical start point
on a Cummins with 30psig max boost is 20 psig.
• Next, adjust “Full Psi” to the engines max boost output.
• Note - over lapping the settings, where the Full dial is lower then
Start, will result in max injection at the onset point.

If pump goes on and fluid level doesn't go down, there is an obstruction
in the tube or nozzle.
Step 2 Test Controller
• Begin the testing process with both dials on the variable controller at
their lowest settings (counter-clockwise).
• Turn ignition key on so that the system has 12 volt power. If the
pump runs, inspect ground wires for secure connection.
• Pump should be off at this point, apply light air pressure into vacuum
tube connection on back of controller. Pump should activate while
low pressure is applied but not enough to completely atomize fluid.
Tuning Quick Reference
If combustion quench occurs as evidenced by engine “bucking”, reduce
the injection quantity or raise the onset boost level. This can be done by:
1. Using a smaller nozzle(s).
2. Introducing injection later at a higher start setting.
Caution******
Prolonged quench may cause lower engine damage over a period of
time.
For setting 3, right, the chart shows the Start dial at 8psi and the Full dial
at 24psi. At 8psig of boost pressure the pump will operate at 10%. At
24psig of boost pressure, the pump will deliver 100% of injection
pressure.
For boost pressure readings between the Start and Full settings, the
controller will linearly adjust the pump pressure as shown on the graph.
Testing the System
Note: for best results, prime pump before use
To clear air from the pump and insure that the system is primed:
• Fill reservoir with water approx ¼ full.
• Remove tubing from the nozzle holder and run tube into
separate container.
• Disconnect green controller wire from red pump wire. 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.
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 pump from controller. Using a 12 volt source, apply power to
red wire of pump. Pump should activate, green LED should go on, 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.
Also, fresh methanol – less than 1 month old when exposed to
atmosphere – and using a greater methanol concentration – up to 50% will reduce combustion quench.
100% water will cool combustion and EGTs and will increase power
approximately 30 HP.
75/25% water/methanol will cool EGTs and power will increase
approximately 45 HP.
50/50% water/methanol will cool EGTs and increase power approx 70+
HP.
Caution: To avoid “pooling” in the intake and possible engine damage
upon start-up, it is recommended that:
1. The engine should be run without water/methanol for at least 5
minutes after injection before turning the engine off.
2. The “armed switch” is turned to the off position when the engine is off.
Tech tip: Do not attempt to inject water/methanol until the engine has
reached operating temperature. A cold engine is more susceptible to
quench and poor performance.
Maintenance –
Remove nozzle(s) and clean screen filters at
least once per year soaking nozzle for 10 min in descaler shower
cleaner.
The Boost Cooler® has been designed to operate with high
concentrations of methanol. Oil or other additives are not required
for system lubrication.
For best performance, cooling and system life it is recommend that
Snow Performance Boost Juice (#40008) be the exclusive fluid used
in the system.
