Water/methanol injection (WMI) systems reduce air inlet temps and enhance combustion efficiency on turbo Diesel applications, which allows an engine to deliver more power with less effort. Water/methanol injection also offers a host of benefits that promote engine longevity, including the reduction of carbon deposits left by a Diesels exhaust gas recirculation (EGR) system. AEMs Water/Methanol Injection Systems for turbo Diesel trucks and SUVs utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol injection system. AEMs on-demand, Boost Dependent progressive controller for its PN 30-3303 tank-less Diesel Water/Methanol Injection kit has an on-board MAP sensor (up to 40 PSI) with a molded in nipple for a boost hose pickup to ensure the proper amount of water/methanol injection at all points along the engines power curve. AEMs engineers spent extensive time developing the HD water/methanol controllers flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engines need for water/methanol injection, which further improves charge air cooling and reduces EGTs. The new HD 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 HD controller housings for mating to the redesigned wiring harnesss positive-lock connector. The Boost Dependent HD controller housing has a molded-in, barbed nipple to accept a boost hose (up to 40 PSI) and a wiring legend on the back. The wiring harnesses for AEMs Water/Methanol Injection kits are terminated with a positive-lock connector on one end and have 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. Features: Boost Dependent HD controller features 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 solenoid Boost Safe failsafe output included Heavy-duty high-pressure injection pump features integral fittings, a Santoprene diaphragm and EPDM seals to resist corrosion. Our pumps quiet, smooth operation is almost undetectable Two precision-machined billet-aluminum injectors with integral check valves include multiple nozzles to cover a wide range of horsepower levels (500 cc/min & two 1,000cc/min) Tank-less Boost Dependent HD Diesel water/methanol system (AEM Part #30-3301 includes Boost-Dependent controller design with on-board 40-PSI MAP sensor and 5 gallon tank) 20 feet of injection tubing included LED dash light for system status and low fluid warning Legal in California only for racing vehicles which may never be used upon a highway. 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. WARNING! 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) Not available for sale in the state of California Click here to read Emissions Notice.
