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 performance naturally aspirated 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.
The on-demand progressive controller in AEM’s Boost Dependent PN30-3300 Water/Methanol Injection kit bases injection flow on manifold pressure using an on-board MAP sensor (up to 35 PSI of boost) to ensure the proper amount of water/methanol injection at all points along an engine’s power curve.
AEM’s engineers spent extensive time developing 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.
The new controller design features 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, integrated fuse and molded mounting tabs.
AEM’s Boost Dependent 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.
AEM’s Boost Dependent, PN 30-3300 gasoline Water/Methanol Injection System’s compact 1 gallon tank includes a high tech conductive low fluid level indicator with a positive lock connector and color matched wires to the wiring harness.
Please Note: The pump includes a ¼” push lock in the box and is self priming.
