This kit is designed for all turbo/supercharged petrol or diesel vehicles, looking to Decrease DET & intake charge temperatures yet maintain or Increase BHP figures. These kits have been proven time and time again in street, race and drag applications. The kit contains all the components needed yet provides a simple and straight forward installation that doesn’t require you to be a mastermind mechanic or tuner to fit. These kits are by far the best available!

Introduction

Water injection systems prevent or suppress detonation. It works by spraying an extremely fine mist direct into the intake manifold at a pre selected boost pressure or in the case of naturally aspirated engines, a pre selected RPM.

Alcohol/methanol injection doesn't do the same things as NOS does. None of the same dangers. It is acting as an intercooler enhancer and octane booster. It can lower the cylinder temps or exhaust gasses by 300 degrees and makes 95 octane fuel basically look like 112 octane.

Fuel accounts for 70% of engine cooling and FACT Water absorbs SIX times more heat than fuel and evaporates instantly inside the intake manifold taking with it a great deal of heat, so you can imagine the massive cooling effect of water injection.

Ever noticed how well your car goes on a cold wet/damp evening well here's an interesting fact: on a rainy day, 1Kg of air at 25C contains about 33ml of water. A typical 2 litre turbo engine consumes over 200cc of water per minute at 6000rpm on a rainy day at 1 bar boost. That's not far off the quantities water injection normally operates at.

As we approach high tuning levels we will experience a considerable increase in cylinder pressure and temperature, but at the same time more power. Since we cannot raise the melting point of the pistons, we must find a way to control and keep the engine components from overheating. Having six times the latent heat of fuel and huge expansion rate from liquid to gas (single molecule of water – not droplets) water is the ideal substance to inject as a coolant. Having absorbed and dealt with the destructive heat, the by-product (superheated steam at x1400 volume increase) becomes an active partner in adding force to the downward pistons, Water is converting the extra heat energy for wheel power. Without water, the excessive heat must be transferred to the cooling system and lost into the atmosphere. Since the quantity of water injected is relative small compared to injecting some six times the amount of fuel to arrive at the same cooling property. To all intent and purposes, we are not advising anyone to go this far but the possibility is there and achievable. In most cases, one can venture into the extreme gently. Since water is free, it costs nothing to continue your quest for a highly efficient engine that produce far more power than the fuel dumping method.

HOW MUCH CAN AIR TEMP EFFECT PERFORMANCE YOU ASK???

From the table below, you will note that air at 0C contains almost 30% more oxygen per given volume, than air at 77C.

Air Temperature
Air Density
% increase of oxygen

77C
0.9950 kg/m^3

40C
1.113 kg/m^3
+ 12% oxygen

27C
1.1614 kg/m^3
+ 17% oxygen

0C
1.2763 kg/m^3
+ 28% oxygen

So if your car is tuned for say 12.0:1 fuel mixture (rich) for maximum power and the air going into your engine is at 77C, you might make say 241bhp @ wheels. Now if you could get that intake air down to 0C and still have your engine tuned at 12.0:1 fuel mixture, you will make 30% more power based simply on oxygen levels in the air = 241bhp @ wheels x 1.3 = 314bhp @ wheels. That’s a massive 73bhp increase!!! Now obviously, unless your using dry ice somewhere along your intake path, you won’t get the air to 0C, but that is just to give you an indication of the true effects of air temps and their relation to power output.

The kit allows you to run higher boost, advance ignition and lean out air fuel ratios.

The Devils Water Injection System is currently in use on the some of the fastest vehicles around, it has applications in drag, drift and circuit racing as well as on the street.

Alcohol does not cause any problems to your engine. It actually "steam" cleans the inside of your throttle body, intake, heads, valves, and exhaust!

Don’t buy a knock-of brand kit with cheap parts for you beloved car, unlike many other brands the Devils pump can run 100% methanol or alcohol as it's chemical resistant or run dry without getting damaged with its EPDM /Nylon valves, Santoprene diaphragm, and adjustable peek pressure from 150 to 300psi. It can also prime itself up to 6ft, so unlike others it doesn’t have to be gravity feed making a lot easier to mount, very handy when space is an issue. This kit only uses the highest quality parts.

The DVS2 Progressive Controller from DevilsOwn is the latest technology we have to offer. Its compact, lightweight, and easy to install. It's designed to give your vehicle stable fluid pressure with a user adjustable range. It contains a high quality built in 4Bar MAP sensor (Boost version), a wide-ranging filtered power supply and a high current switching MOSFET transistor. 

Controller General Operation:

• Unit will read/save START and END dial settings. (END Point is where Pump is fully on)
• Pump duty cycle is calculated based on saved dial settings and input reading.
• When input reading reaches the saved START setting, the pump will activate with a 20% duty cycle.
• Duty cycle will ramp up to 100% as input reading reaches the saved END point where the pump will remain fully on.
• The duty cycle percentage increases and is a direct correlation between the input reading (boost or voltage) and saved dial values. This means the pump output will be a completely analogue linear response.
• Optional dual stage (referred to as "Stage 2")
• Controller available as:-
• Selectable Boost (Built-in 4Bar map sensor) or Voltage
• Voltage Input Only

If the END setting is set to a lower value than the START setting. the controller automatically sets the END point to the START point. The pump will then activate at a 100% duty cycle when value is equal to the START setting. It will then switch off when it is below the START setting. If dual stage is enabled, this will also activate. see settings examples.

Example 1

Boost Start 2psi End PSI 33psi – No Stage 2

The graph shows the linear duty to psi response.

Example 2

Boost Start 5psi End PSI 20psi – Stage 2 Enabled

The graph shows the linear duty to psi as well as the stage2 starting at 90% Pump Duty Cycle/18psi.

Example 3

Boost Start 15psi End PSI 15psi – Stage 2 Enabled

With the duty cycle going from 0 to 100% at one single point the Stage 2 solenoid would activate at the same instant.

 Voltage Input (white cable)

To prevent loading down the MAP sensor signal, the voltage input to the controller is left floating. This means that tapping into the stock MAP sensor that is connected to your car’s computer will not affect the MAP voltage. However, if the MAP input wire (white) is left disconnected, sampled voltage will be erratic and therefore pump output duty cycle will be erratic.

LEDs:

• Green - This led will light up or flash whenever the controller has power
• Blue - This led will light up whenever flow starts. its brightness is dependent on the duty cycle value and stage 2 activation.
• Yellow - This led will flash for 10 seconds whenever a low fluid level has been detected.
• Red - Fault led - It will be illuminated anytime there is a fault detected by the additional add-on failsafe.

Controller specs:

• Ignition Voltage 8 to 36v
• Standby Current 20ma
• Pump Pulse Width Modulation (PWM) Frequency 60hz
• Duty Cycle 20%-100%
• 100% Duty Cycle 20A
• Sensor Voltage Input Range 0-5v
