Methanol Injection Kit

Water/methanol injection can reduce engine inlet air temperatures and inhibit dangerous detonation successfully for forced induction gas-powered race engines. It allows racers to boost and advance ignition timing with confidence, resulting in up to 20% power improvements. AEM Water/Methanol Injection Kits have higher advanced features and sturdier hardware than any other injection system.

What Is Water/Methanol Injection?

Water/Methanol injection is a method of decreasing air inlet temperatures by injecting an atomised water and methanol fuel mixture into a car’s intake (or cold charge pipe). It also raises the octane level to prevent detonation or knock. Detonation occurs when fuel and air ignite too quickly during the ignition cycle, causing forces in the combustion chamber to expand.

The piston is still going upward during the explosion, but forces attempt to push it back down. As a result, the energy is transferred and generates various effects, including piston damage from “piston slap,” The piston is then forced against the cylinder walls, forging piston rings. Detonation can occur due to various factors, including temperature, improper tuning, and mechanical issues.

Working Of Water/Methanol Injection

A variety makes water/methanol kits for businesses, and no two are the same. Some are pretty basic and inexpensive, while others are a little more costly and intricate. A tank, a pump, a nozzle, and some type of control unit are the four essential components of most kits.

The AEM kit includes a control unit with two control knobs and a built-in boost sensor. The first knob regulates the PSI at which the system begins spraying the water meth mix, and the second knob controls the PSI at which it stops. A light on the unit also indicates when your tank is running low. A “jet” that goes into the water meth nozzle and then into the intake system controls the amount of water meth in this system.

The water-methanol tank is usually present at the back of the car, with the pump conveniently located nearby. Most kits also include an extra filter that you can use. The water meth pump uses a nylon tube to extract the mixture from the tank. The tube then exits the pump and travels to the nozzle at the front of the car.

The majority of systems are simple to install, although some have connections to the vehicle’s electronics. These are excellent solutions, but they can be challenging to set up on your own. Anyone who is moderately skilled around a car can install the most basic water meth kits in an afternoon.

Benefits Of Water/Methanol Injection

  • Methanol’s high-octane qualities, along with the methanol and water’s air cooling properties, help water/methanol systems produce more power. Furthermore, the reduced intake temps enable you to run more aggressively, timing and boost without risking detonation.
  • Because the methanol and water provide lower intake charge temperatures, there’s less possibility of engine damage from detonation. The atomised water steam cleans the valves, valve seats, and even the piston tops and intake in some circumstances, eliminating carbon accumulation.

Using a water/methanol system can increase the timing by 10 degrees or more depending on the system. In power-adder applications, these adjustments, when paired with the cooler air intake charge provided by the water and methanol, can result in a horsepower gain of up to 20%. If the flow of water/methanol is exhausted or dips suddenly, most systems contain a fail-safe device that reduces boost or modifies timing curves.
