Installing An AEM Water / Methanol Injection Kit - Tow, Chase Haul!

If you own a vehicle with a turbo or supercharger and are looking for more power, a water/methanol injection kit might be just what you need. One of the problems and limiting factors to forced induction is that it heats up the intake and exhaust of an engine. Water has the remarkable ability to absorb a lot of heat and, when injected into an engine's intake airstream, can significantly reduce temperatures. Boost and fueling might be increased for more power, with little or no increase in intake-exhaust temps, if water injection is added.

Methanol is often mixed with the water because it is a very high octane fuel and burns much cooler and slower than pump gas. The ratio of water to methanol can be adjusted depending on the application and desired results. For more cooling effect, a larger percentage of water, up to 100 percent, could be injected. If maximum horsepower is desired, up to 50 percent methanol, can be used.

AEM recently released a universal water/methanol kit that will work with just about any turbo, supercharged, gas, or diesel engine. By monitoring the intake-boost pressure, a controller activates and regulates the water/meth injection. The control module is user-tunable so that you can set at what boost injection begins and then at what boost full injection occurs. Three different injector sizes are included.

Here's an example of the wide range of applications: While an acquaintance is using this kit on a late-model BMW 335i sedan, we are using the same kit on our modified Cummins turbo diesel Ram truck.
