Water Methanol Injection

Water methanol injection is the introduction of a 1:1 ratio of water and methanol, like "Boost Juice", into an engine with or without boost (from a turbocharger or supercharger) to help produce more power by cooling or raising the effective octane level of the fuel. It can be used in both street and racing applications.

When injecting water methanol into the engine inlet with a high pressure pump, hose, and nozzle, it helps to prevent detonation (when air/fuel mixture heats up and explodes from compression and pressure before the spark plug ignites), which can lead to engine damage. It also cools the air/fuel mixture temperature, which results in horsepower and torque increases. Water methanol injection also increases the octane level of gas and fuel, allowing for performance ignition timing and higher compression in engines with the same octane gas in the fuel tank.

The main benefits of methanol injection fluid on diesel engines are reducing exhaust gas temperatures and cooling the intake air charge, usually on turbocharged engines. This results in a noticeable increase in horsepower and torque.

Depending on the manufacturer and kit type, the installation steps will change. However, most involve mounting the reservoir as high in the engine compartment as possible. The pump is then mounted at or below the bottom level of the reservoir for the best operation of the water methanol fluid system. A specific diameter nozzle is utilized to ensure enough fluid is used to produce benefits, but not too much that would create "bore wash" in the cylinders. A cooler ring introduces the correct amount of fluid into the engine's intake tract via a hose (typically nylon) connection along with the nozzle. Water methanol injection modules are included with some kits to help control the amount of fluid based on engine speed and other parameters.
