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.
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.
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.
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.
