Make tremendous amounts of power on pump gas!

Water/Methanol/Alcohol injection commonly referred to as WMI allows you to make tremendous amounts of power on pump gas. The effect is similar to running 100 octane race gas or E85 fuel all the time with the additional cooling benefits allowing for more power than you can make on race gas or E85 alone.

The key to a safe and effective WMI setup is tuning integration. The JB4 WMI kit integrates with the JB4 tuning system allowing for precise mapping based on boost, throttle position, engine speed, intake temperature, advance, gear, and other data elements available to the JB4 through its CANbus system. In addition, a pump flow signal is fed back to the JB4 allowing for a safe and smooth progressive boost mapping. If the tank runs empty or the flow drops for any reason the JB4 will safely back down performance to avoid detonation. Boost is held low until WMI is properly flowing to avoid tip in knock common with non-integrated WMI setups. In addition, WMI can be activated or disabled right from the JB4 Mobile app, will automatically disengage during traction control or safety map situations, and WMI flow data can be displayed via your JB4 Mobile logging device.

The BMS WMI kit includes a high quality Aquatec WMI pump made to our specifications, high speed solenoid with leak-free compression fittings, a WMI filter, and all required wiring and mounting hardware. 

We offer a unique direct fit nozzle mount adapter for the platform eliminating the need to drill/tap a nozzle or tig weld to your factory charge pipe.

Note: If using the optional Stinger stealth bracket the spare tire needs to be deflated or removed.

The base kit includes our WMI pump, FSB controller for the JB4, solenoid, filter, 20' of WMI line, compression fittings, and wiring.

In addition, you'll need to add on your nozzle (we suggest single BM10 for 3.3L, BM7 for 1.6-2L), tank, and optional items such as our quick install nozzle adapter or stealth bracket if you selected the 1-gallon tank.
