Holley EFI 557-101 Water Methanol Installation Kit

Take your forced induction ride to the next level with a Holley water/methanol injection system. Integrated into the Holley Dominator and HP EFI systems is the capability to control water/methanol injection, allowing you to safely run on lower octane pump gas. What makes our system unique and light years ahead of competitive systems is that the solenoid flow has been characterized within the ECU. Program in an exact flow amount into the software and that flow is injected into the engine. This is critical to ensure that neither too little (causing engine damage), nor too much (causing a large loss in power) water/methanol mix is injected into the engine. Select the exact percentage of water/methanol mix to be delivered vs. the percentage of fuel flow present, at any RPM and load. This makes tuning a very simple and accurate process. All components are designed to be compatible with water/methanol mix of up to 50% methanol.
