Water/Methanol Injection Systems
Water/Methanol Injections Systems reduce intake temps and exhaust gas
temps and suppress harmful detonation on turbocharged, supercharged, and
high compression naturally aspirated racing engines. This reduces knock
and allows you to increase boost and timing without using higher octane
racing fuel to achieve power gains up to 20%.
Every AEM water-methanol injection (WMI) system comes with robust
hardware and delivers more advanced features than comparably priced
competitors. The intuitive and ergonomic controller design of our
methanol fuel injection systems allows for easy access and adjustment,

Technology improves atomization for faster inlet temp cooling using less

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.
Innovative Injector Design Delivers Faster Cooling with Less Fluid Used
Our breakthrough injector design uses unique Swirl Generator Technology that improves atomization to deliver faster inlet temp cooling and uses less fluid to maintain inlet air cooling. We include three Swirl Generators that deliver 250cc, 500cc, and 1000cc of flow. The AEM V3 WMI injector is included in every AEM Water/Methanol injection kit and is a direct replacement/upgrade for the V2 injector in older systems (V3 Injector PN 30-3315).
In testing at AEM, the new V3 250cc WMI nozzle and the V2 250cc WMI nozzle both achieved a 90-degree inlet temp reduction; however, the V3 nozzle design achieved this reduction nearly 6.5 seconds faster. Consider that on an average sportsman drag car this can represent close to 40% of track time. On a road race car, applying more timing 6.5 seconds faster can mean a critical time to pass on a corner exit.
We then tested a V3 250cc injector against a V2 500cc injector to see if the larger V2 injector would improve cooling speed. The V2 500cc injector achieved nearly identical cooling speed as the V3 250cc injector, but it required almost 44% more fluid to achieve the same cooling. Less fluid used means fewer refills of your WMI tank and less money spent refilling it. Using the V2 500cc nozzle with a one-gallon tank, you will get close to 7 minutes and 50 seconds of run time at full pressure. Using the V3 250cc nozzle with a one-gallon tank, you will get 13 minutes and 30 seconds of run time at full pressure.

Heavy-Duty Waterproof High Pressure Injection Pump - Safe for Engine Bay/Frame Rail Mounting
AEM’s internally-bypassed water/methanol injection pump is waterproof and safe for mounting in loactions that are exposed the elements. It 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 1.15 Gallon Tank
AEM’s gas Water/Methanol Injection Systems are available with or without a compact 1.15 gallon tank that features an anti-starvation reservoir. 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.
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.
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.
