The advantages of these kits are that they allow you to increase boost pressure and advance timing without having to run higher octane fuel. These kits are also effective for reducing engine inlet air temperatures and suppressing harmful detonation. Using this water/methanol kit can increase power by up to 20% on forced induction engines.
This kit includes a multiple input controller that allows users to install the kit on ultra-high boost vehicles over 35PSI using a 0-5V voltage-based external MAP sensor. The controller also works with input from injector duty cycle, frequency-based MAF, or 0.5V voltage-based MAF, making it suitable for use on high-compression NA engines. The kit is also supplied with a fluid level sensor to detect if the fluid in the system is running low or has an error. Once installed, adjustments can be made to control the amount of water/methanol mixture fed into the inlet stream from the reservoir via the included injectors, potentially resulting in significant horsepower gains.
Kits are available in 2 different options:
Option 1 - 1.15 gallon tank, with integral anti-starvation reservoir, and a single injector suitable for NA or forced induction petrol engines.
Option 2 - Five gallon tank with 2 injectors suitable for high output diesel and petrol engines.
This kit includes:
- Multi-Input controller
- Wiring harness
- Boost Safe failsafe output
- Heavy-duty high-pressure injection pump with integral fittings, a Santoprene diaphragm, and EPDM seals to resist corrosion
- Precision-machined billet-aluminum injector with integral check valve
- Injector nozzles
- 1.15 gallon tank with anti-starvation reservoir
- 20 feet of injection tubing included
- LED dash light for system status and low fluid warning
The AEM Electronics Water/Methanol Injection Kit (30-3350) is designed for both forced induction and naturally aspirated (NA) vehicles looking to enhance performance and engine safety. Its primary benefit is enabling increased boost pressure and advanced timing without requiring higher octane fuel, while also reducing inlet air temperatures and suppressing detonation, potentially boosting power by up to 20% on forced induction setups. A key consideration is the need for proper installation and tuning to achieve optimal results and avoid potential engine damage.

FAQs
What is the optimal water/methanol mixture ratio?
A 50/50 mixture of distilled water and methanol is generally recommended for most applications. This provides a balance between cooling effect and octane enhancement.
Can I use regular tap water instead of distilled water?
No, it is crucial to use distilled water. Tap water contains minerals that can clog the injection system components and potentially damage the pump or injector.
How often do I need to refill the tank?
Refill frequency depends on the size of the tank and how aggressively the system is used. The 1.15-gallon tank may need refilling every few weeks for daily drivers, while the 5-gallon tank lasts much longer for high-demand use.
Do I need a specific type of methanol?
Use pure methanol (99.8% or higher). Do not use denatured alcohol, as it often contains additives that can harm the system.
What is the benefit of the Boost Safe failsafe output?
The Boost Safe output provides a signal that can be used to alert the driver or cut engine power if a system malfunction occurs (like running out of fluid), helping to prevent engine damage.
How does this system increase horsepower?
By injecting a water/methanol mixture, the system cools the intake charge and increases the fuel's effective octane rating. This allows the engine to run more advanced ignition timing and higher boost pressures without detonating, leading to increased power.
Can this kit be used on a car without forced induction?
Yes, the kit is also effective for naturally aspirated engines, particularly those with high compression ratios, by reducing combustion temperatures and preventing detonation.
Troubleshooting
System does not inject fluid
Check pump power connection, ensure fluid level is adequate, verify injector is not clogged, and confirm controller is providing an activation signal.
Low fluid warning light stays on
Check the fluid level sensor connection and ensure it is properly seated in the reservoir. Clean the sensor if debris is present.
Engine performance issues after installation
Verify all electrical connections are secure and correct according to the wiring diagram. Double-check controller settings and consult a professional tuner.
Pump is noisy or not running
Ensure the pump is receiving proper voltage and is not air-locked. Check for any obstructions in the pump inlet or outlet.
Failsafe output not engaging
Confirm the Boost Safe output is correctly wired and that the trigger condition for the failsafe is met (e.g., low fluid, system error).

Setup, Compatibility & Care Instructions
Setup:
Component Placement: Identify suitable locations for the pump, reservoir, controller, and injector.
Fluid Reservoir: Fill the reservoir with a 50/50 mixture of distilled water and methanol. Never use pure water or methanol.
Tubing Installation: Route the injection tubing from the pump to the injector, ensuring no kinks or sharp bends.
Electrical Connections: Connect the controller to appropriate power, ground, and sensor inputs (MAP, MAF, or injector duty cycle) as per the wiring diagram.
Injector Installation: Mount the injector in the intake tract before the throttle body or turbocharger compressor outlet.
Failsafe Configuration: Connect the Boost Safe failsafe output to a diagnostic port or management system if desired.
Calibration: Adjust the controller settings based on engine parameters and desired injection rate. Professional tuning is highly recommended.
Compatibility:
Forced Induction Engines: Turbocharged or supercharged gasoline engines.
