Manufacturer notes

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 Precision-machined billet-aluminum injector with integral check valve Three interchangeable injector nozzles to cover a wide variety of HP levels (250cc/min, 500 cc/min & 1,000cc/min) 1.15-gallon tank with anti-starvation reservoir, integral conductive low-fluid sensor and positive lock connector (tank-less systems available) 20 feet of injection tubing included LED dash light for system status and low fluid warning

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.

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.

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.

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.

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.

The sensor eliminates any chance of incorrect readings due to interference from debris.

About the manufacturer

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 Injection Kits utilize robust hardware and deliver more advanced features than any other comparably priced water/methanol injection system.

Note: FOR OPTIMUM RESULTS, ALL WATER/METHANOL INJECTION SYSTEMS AND FLOW GAUGES SHOULD BE RUN WITH AN WMI INLINE FILTER (PN 30-3003). For additional insurance against unintended flow, particularly when the pump and tank must be installed higher than the injections nozzle, we recommend adding our optional High-Flow Low-Current WMI Solenoid (PN 30-3326).

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.
