WATER/METHANOL INJECTION SYSTEMS FOR FORCED INDUCTION & HIGH COMPRESSION NATURALLY ASPIRATED GAS ENGINES
Water/Methanol’s Liquid Intercooling Effect Delivers Race Gas Performance on Pump Gas
The Benefits of Water/Methanol Injection for Gas Engines
THE AEM WATER/METHANOL INJECTION SYSTEM ADVANTAGE Water/methanol injection for gas engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation on forced induction and high compression naturally aspirated (NA) race engines. 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 Naturally Aspirated and Forced Induction Gas Engines AEM offers two different water/methanol controller designs for gas vehicles.
One is boost dependent (Kit Part #30-3300) for forced induction vehicles up to 35 PSI of boost. 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 Part #30-3350) features a multiple input design that enables users to install AEM’s Water/Methanol Injection Kit on both high compression naturally aspirated vehicles (NA) via the MAF/IDC settings and ultra-high boost vehicles (above 35 PSI) using an external MAP sensor. The Multi-Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF.
Robust, Easy to Use Controller Designs The new controller designs 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. The Multi-Input controller has an easy-to-remove plug covering the programming dipswitches and a programming legend on the back for the 0-5v and frequency based settings. 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 (see graph below).
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.

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.
Improper installation and/or adjustment of this product can result in major engine/vehicle damage. For technical assistance visit our forum or visit our dealer locator to find a professional installer/tuner near you.
Note: AEM holds no responsibility for any engine damage or personal injury that results from the misuse of this product, including but not limited to injury or death caused by the mishandling of methanol.
Note: FOR OPTIMUM RESULTS, ALL WATER/METHANOL INJECTION SYSTEMS AND GAUGES SHOULD BE RUN WITH AN AEM INLINE FILTER (AEM PART #30-3003)
