Description

AEM V2 Water/Methanol Injection Kit Multi Input (No Tank)

• AEM’s Water/Methanol Injection System 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.

• Water has a very high heat of vaporization. As the ambient temperature water is injected into the engine, heat transfers from the hot cylinder head/intake air into the water. This makes it evaporate, cooling the intake charge. A cooler intake charge means it is more dense (higher volumetric efficiency) and also has a lower tendency to knock. However, the water vapor displaces some air, negating some of the denser intake charge benefit. Knocking is generally more of a problem in forced induction engines rather than naturally aspirated, so this can help prevent it. On electronic ignition systems the ignition timing is generally retarded to prevent knock from occurring but with water injection it can be advanced closer to Maximum Brake Torque (MBT) timing for additional power.
