THE AEM WATER/METHANOL INJECTION SYSTEM ADVANTAGE
Water/methanol injection for forced induction (turbocharged or supercharged)
gas-powered race engines is a proven means for effectively reducing engine
inlet air temperatures and suppressing harmful detonation. This allows racers
to reliably increase boost and advance ignition timing—without using
high-octane racing fuel—for power gains of up to 20%. AEM’s Water/Methanol
Injection Systems utilize the most robust hardware combined with more advanced
features than any other comparably priced water/methanol system.
Water/Methanol for All Boost Levels of Forced Induction Gas Race Engines
AEM offers two different water/methanol controller designs for gas vehicles:
One is boost dependent for forced induction vehicles up to 35 PSI of boost
(kit PN 30-3300). The Boost Dependent controller has an on-board manifold
absolute pressure (MAP) sensor with a molded-in nipple for a boost hose pickup.
The second controller (Kit PN 30-3350) features a multiple input design
that enables users to install AEM’s Water/Methanol Injection Kit on ultra-high
boost vehicles (above 35 PSI) using a 0-5v voltage-based external MAP sensor.
Robust, Easy to Use Controller Designs
The new controller designs (Boost Dependent Kit PN 30-3300 & Multi Input
Kit PN 30-3350) feature large, turn-resistant knobs and larger numbering to
easily set accurate start and full activation points, with covered status LED
and test buttons for added splash resistance. A plug is integrated into the controller
housing for mating to the redesigned wiring harness’s positive-lock connector.
The Boost Dependent controller housing has a molded-in, barbed nipple to accept
a boost hose and a wiring legend on the back. Both controller housings feature
an easy to access integrated fuse and molded mounting tabs.
Simplified Wiring
AEM’s Water/Methanol Injection kit’s wiring harness is terminated with a
positive-lock connector on one end and has color-coded wires to ease
installation. Both the power and ground wires for the pump are included in the
harness which simplifies the wiring process and eliminates any chance of the
pump accidentally activating from a short in the system. An additional wire is
included for adding an optional on/off solenoid to stop fluid flow when the
system is inactive.
Integrated Boost Safe Feature
The controllers in AEM’s Water Methanol systems include an integrated “Boost
Safe” output feature that monitors the entire injection system and triggers a
ground signal via an output if it detects a voltage-related error (short, bad
connection, broken wire, overheated pump, high or low voltage signal, etc.),
allowing users to define their failsafe strategy from something as simple as
flashing a warning light to more advanced strategies like pulling boost or
ignition, or switching fuel maps on a standalone engine management system.
Combined with the integral and highly accurate conductive low-fluid switch in
the tank, “Boost Safe” can also put your engine in safe mode before the system
runs dry. This exclusive feature is found only on AEM Water/Methanol Injection
Systems.
Heavy-Duty High Pressure Injection Pump
AEM’s internally-bypassed water/methanol injection pump does not cycle on and
off and provides quiet, smooth operation. It features robust construction
including integral hose fittings, EPDM seals and a Santoprene diaphragm that
provides consistent and reliable fluid delivery.
Low-Profile 1 Gallon Tank
AEM’s gas Water/Methanol Injection Systems are available with or without a
compact 1 gallon tank. A more accurate, conductive low level fluid sensor is
integrated into the tank and features a positive lock connector with
color-matched wires to the wiring harness. The sensor eliminates any chance of
incorrect readings due to interference from debris.
Machined Billet Injectors and Nozzles
AEM includes one precision-machined billet injector in its gasoline
Water/Methanol Injection kit. It features an integral check valve to prevent
unintended fluid flow. Three billet injector nozzles are included for matching
water/methanol flow to an engine’s horsepower output.
Revised Flow Control Strategy for More Linear Fluid Delivery
AEM’s engineers spent extensive time revamping the controller’s flow control
strategy for a more linear flow output delivery. This means that the flow
delivery better matches an engine’s need for water/methanol injection, which
further optimizes charge air cooling and detonation control.
Boost Dependent and Multi-Input (0-5v/frequency) progressive controller
designs feature large adjustment knobs, integrated plug for harness connection,
integrated fuse, covered status light and test button for enhanced splash
resistance and mounting tabs
Wiring harness is terminated with a positive-lock connector on one end with
color-coded wires to ease installation, integrated pump ground circuit and
additional wire for optional on/off fluid solenoid
“Boost Safe” failsafe output included (for complete failsafe under all
conditions, see our Water/Methanol Failsafe Device)
Heavy-duty high-pressure injection pump features integral fittings, a
Santoprene diaphragm and EPDM seals to resist corrosion. Our pump maximizes
line pressure for optimum atomization and its quiet, smooth operation is almost
undetectable

WATER/METHANOL INJECTION ADVANTAGES FOR GAS ENGINES:
Reduces Air Inlet Charge Temps
The term “liquid intercooling” with water/methanol injection refers to a highly
atomized mist of water/methanol that is injected into the airstream and begins
to evaporate. As it does, this evaporative effect reduces air charge temps by
as much as 100 degrees, and delivers a more oxygen-rich air charge.
Reduces Detonation (Knock)
Water absorbs heat, and methanol is a cool burning, anti-knock rated fuel. When
combined and introduced into the inlet stream, they can effectively increase
your vehicle’s anti-knock index so you can reliably increase boost pressure and
advance ignition timing using pump gas.
Reduces Carbon Deposits
Modern vehicles fitted with Exhaust Gas Recirculation (EGR) devices for
emissions control promote heavy carbon build up inside the air intake. This
carbon build-up can create ‘hot spots’ in the combustion chambers that can
cause detonation. Water/methanol injection has a ‘steam cleaning’ effect that
reduces this carbon build up, and in some cases can increase fuel economy.
Important Safety Notice Regarding Methanol
AEM strongly recommends that users never
exceed a 50% methanol concentration when using any AEM Water Methanol system or
component.
All AEM Water/Methanol injection systems
and components (pump, lines, fittings, filter, flow sensor, tank, and nozzles)
are 100% chemically compatible with methanol. However, for safety reasons we
strongly recommend that users never use more than a 50% methanol concentration
in our systems.
Methanol is a toxic and highly flammable
chemical. 100% Methanol ignites easily and burns vigorously with an almost
undetectable flame. Methanol can be absorbed through the skin and even small
amounts can cause blindness or even death. Using this fluid at high pressures,
without dilution, in an under-hood environment with nylon lines and push-to-connect
fittings is very unsafe. The performance advantages of using greater than 50%
methanol concentrations are small, if they exist at all. However, the safety
issues are very real and far outweigh any perceived benefit of running high
concentrations of methanol.
