Water / Methanol Injection Kit
AEM Water/Methanol Injection Kits reduce air inlet temperatures which allows users to increase boost pressure (and advance timing on forced induction gas applications) to create more power by utilizing the cooling effects of the system under heavy load. The kit is offered in 2 configurations: a 1-Gallon kit for racecar applications, and a 5- Gallon HD kit for Diesel applications or racecars requiring extended range. Both kits include all the elements necessary to do water/methanol injection right, including a standard fluid level sensor for the tank, recirculation-style pump, feature-loaded controller, and complete hardware for installation on practically any diesel or gas application. For users who intend to use a custom or existing reservoir, AEM also offers a “tankless” pump and jet kit. There are no hidden costs or additional components required.



Once the AEM Water/Methanol Kit is installed, a boost-dependent, variable-flow progressive controller allows the user to determine the amount of water/methanol mixture (up to 50%) to feed into the inlet stream from the fluid reservoir. The controller commands a high-pressure, recirculation-style 150-PSI pump that delivers the mixture. Overall flow adjustments at the inlet are made via one of three different-sized jets (included) that are designed to match most engine power requirements.


AEM's recirculation-style pump offers improved performance, reliability and a much smoother, quieter operation when compared to older switched-style pumps. With the use of a new internal bypass design, AEM's upgraded pump eliminates erratic on and off switching/pulsing and ensures consistent fluid delivery for optimum performance. With durability and reliability in mind, AEM has designed the pump with a Santoprene diaphragm and EPDM seals to withstand the harshest of alcohol mixes.


All AEM Water/Methanol controllers include a Boost Safe feature. This feature allows users to retard timing or reduce boost via a ground output if the system runs out of fluid or detects a controller error, ensuring fail-safe operation of the engine whether the system is engaged or not. Critical safety features are integrated into the system to virtually eliminate any chance of failure, including an integral fluid level sensor in the reservoir, internal controller diagnostics and an LED dash light to warn of low fluid level or error codes (including short circuits.

The Proof is in the POWER!

We recently tuned a 95 VR4 with these Executioners and netted 478 AWHP and 416 AWTQ.  Below is the dyno chart and modifications on the car, dyno tuned on our AWD Dyno.

October 2010 Update: The car above revisited 3SX for an AEM Meth Injection Kit install and retune..... The net numbers were 529hp and 509tq on pump 93 octane and some more boost (meth kit benefit).

Not bad for a "basic bolt-ons" modded car... ;-)
