WMI Stage 2 V3 Dual Nozzle

R9 850

or R1 067 per month for 12 months*


A complete Stage 2 Progressive Dual Nozzle System including 4 different nozzle sizes, Level Monitor, System Pressure Monitor and a 3.8L Reservoir to allow for use on a range of platforms with varying modifications.



This Cool Boost Systems Stage 2 DNS Water-Methanol Injection Kit is a system designed for individuals requiring a single nozzle injection setup with fluid delivery in a progressive manner based on boost pressure.

This system includes a Progressive Pump Controller allowing the driver or tuner to adjust on the fly what Boost Pressure range they require the benefits of W/M injection.

Because this system is not suited specifically to a particular vehicle, it includes a range of varying flow rate nozzles to allow for fine tuning for optimal results on different platforms.

This Stage 2 DNS Water-Methanol Injection Kit is complete in every way and includes all the necessary hardware to allow for ease of installation on your vehicle.


Key Features of the Stage 2 Controller in this system:

*Set & Forget Setpoint Adjustments

This great feature prevents changes to your injection setpoints by accidental cleaning, vibration or temperature change.


*Manual System Priming Feature

Our Controllers allow for the driver to prime the system as desired from the comfort of the interior whilst stationary or driving.


*System Test Function *NEW*

Our Controllers incorporate a built-in Test feature to allow the driver to test the system where the controller will run the pump until pressure is detected by our unique SPMU Sensor.

Should the system take too long to either pressurise or depressurise the controller will indicate these two states allowing for easy diagnosis.


*Controller Failure and Wiring Defect Detection

Our controller monitors the Pump and Solenoid Outputs continously, actually to be exact, every 10ms.

Should anything be amiss, the controller will instantaneously interlock runaway injection, all whilst activating the Boost Safe Output which will place the vehicle into a limp mode so that damage cannot occur.


*System Pre-Pressurisation Technology *NEW*

To prevent latency, our controllers preempt an “ON” condition and pre-pressurises the system in advance.

This has proven to provide more consistancy and prevents manual priming on vehicles that do not drive often or have high injection activate setpoints.


*3 Stage Electrical Isolation

Should any electrical failures occur, the system has to go through 3 levels of “hot wiring” or failures before runaway system injection could ever occur.

This has proved Cool Boost Systems to be safest in the world and we have the “zero engine hydro-lock” reputation to prove that.


*System Pressure Monitoring

Our Stage 2 Universal kits are equipped with a System Pressure Monitor which monitor system pressure and allows for easy detection of issues such as blocked nozzles and low pressures.

Low Pressure failures attribute to fluid flow restriction from blockages in the pump or system anti-siphon devices are very easily detected, isolated and reported on the controller face.


*Fluid Level Monitoring

Should the system begin to run low on fluid, our Universal Stage 2 kits include a Fluid Level Switch which will alarm this condition on the controller face.


Quick Benefits Of Water-Methanol Injection

* Increase power output safely by 15-20%

* Lower air temperatures by 10-100°C degrees

* Increases octane by up to 25 RON and only when you need it in boost

* Reduces cylinder temperatures up to 150°C degrees

* Detonation and Pre-Ignition becomes a distant memory

* No wear issues only clean combustion chambers

* Allows you to safely run more boost and timing


So you now know what it can do, what does it do to your vehicle’s engine?

A Water-Methanol Injection Kit’s main purpose is to suppress detonation caused by high temperature and pressure that has developed in the combustion chamber when the effective compression ratio has been taken beyond the auto-ignition point, by either a turbo, supercharger or high compression pistons.

Compressed air is heated air that causes a reduction of power and increases the likelihood of detonation.

Our kits help lessen any reduction of power while also increasing fuel economy by instantly cooling the compressed air in the boost pipes before the throttle body and also in the combustion chambers during ignition.

Because Water and Methanol have a very high latent heat content, it is extremely effective for controlling not only the onset of detonation but also the production of oxides of nitrogen in modern lean burning engines.

Methanol, with its 116 octane high flash points and specific gravity, helps further reduce the chances of detonation and acts as a fuel itself in the combustion chamber.
