Product Description
The AEM Electronics Water/Methanol Injection Kit With HD Controller is suitable for forced-induction HD & turbo diesel applications. These kits allow you to increase boost pressure and enhance combustion efficiency. They effectively lower engine inlet air temperatures, suppress harmful detonation and reduce carbon deposits left by a diesel's EGR system, whilst increasing engine power by up to 20%.Allows higher boost and increased ignition advance for better powerPrevents engine damaging pre-ignitionComprehensive kit with all wiring and plumbingA Fluid level sensor alerts when the tank is running low or if there is an errorThis kit uses a Boost Dependent progressive type, controller. This means that fluid will be injected in proportion to the amount of boost that is detected by the internal Mass Air Pressure (MAP) sensor. In other words, more boost equals more fluid. The controller housing has a moulded-in barbed nipple to accept a boost hose and a wiring legend on the back for easy installation. The HD Boost Dependent controller is designed for forced induction diesel engines with a 5-40 PSI maximum boost range. This makes it suitable for use on forced induction engines in HD & turbo diesel trucks/SUV's.The robust controller construction also features large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, covered status LED and test buttons for added splash resistance, a rear integrated positive-lock socket/connector system for securing the controller's redesigned colour-coded wiring harness and an easy to access integrated fuse and moulded mounting tabs.The kit is also supplied with a more accurate conductive fluid level sensor integrated into the 5-gallon tank, so it can detect if the fluid in the system is getting low or has an error. Once the system is installed adjustments can be made to control the amount of water/methanol mixture that is fed into the inlet stream from the reservoir via the included innovative V3 injectors, which can result in significant horsepower gains.The V3 injector is a direct replacement/upgrade for the previous V2 design and uses unique Swirl Generator Technology that improves atomization, to deliver faster inlet temp cooling and uses less fluid to maintain inlet air cooling. Three interchangeable nozzles are included that deliver 250cc, 500cc, and 1000cc of flow.AEM's internally-bypassed water/methanol injection pump is waterproof and safe for mounting in locations that are exposed to 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.AEM's Water/Methanol controllers 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 warning light to more advanced strategies like pulling boost or ignition or switching fuel maps on a standalone engine management system. When combined with the integral and highly accurate conductive low-fluid switch found in AEM tanks, "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 SystemsThis kit includes:Terminated harness with positive lock connector, power and ground wires and additional wire for optional on/off solenoid5 Gallon tank with built-in conductive low fluid level indicatorIncludes "Boost Safe" readiness failsafe systemTwo machined billet injectors with integral check valves to prevent unintended flowThree interchangeable injector nozzles to cover a wide variety of HP levels (one 500 cc/min nozzle & two 1,000cc/min nozzles)200 PSI Recirculation-style pump with integral fittings for quiet operationLED dash light for system status and low fluid warning20 ft. of high-pressure Nylon injection tubing
