JB4 Universal Water/Methanol Injection (WMI) Kit

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.

FSB JB4 Water/Methanol Injection (WMI) controller

The BMS JB4 FSB Water/Methanol Injection (WMI) controller allows the JB4 to control your WMI pump and solenoid for dynamic progressive flow mapping. It also allows the JB4 to monitor pump current to overlay it with CANbus feedback for tuning parameters such as fuel trims and fuel pressure to provide a comprehensive flow-based safety system.

The key to a safe and effective Water/Methanol Injection (WMI) setup is tuning integration. All BMS kits integrate to 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 flow drops for any reason the JB4 will safely back down performance to avoid knock. In addition, WMI can be activated or disabled from the driver’s seat, will automatically disengage during traction control or safety map situations, and WMI flow data can be displayed in dash and/or via your JB4 Mobile logging device.

BMS kits include a high quality 220psi Aquatec WMI pump (the industry standard), methanol compatible solenoid with filter, compression fittings reducing the risk of dangerous leaks, and all required wiring and mounting hardware.

The base kit includes a WMI pump, solenoid, FSB for JB4 integration, WMI solenoid, filter, 20' of WMI line, and required fittings. Using the options when adding to cart you can add on a WMI nozzle (BM10 suggested for most applications), tank, and optional checkvalve tank tap to keep vapors inside the tank.

Optional check valve tank tap to keep vapors inside the tank is available at the bottom of the page

Injection Nozzle Options: (Single or Dual Nozzles)

The nozzles are determined by the intended power and how many bungs your charge pipe has. The nozzles are 1/8” NPT and screw into bungs included on most aftermarket charge pipes. Our "super atomizing" nozzles are well known for their great atomization and flow characteristics. The nozzle number represents the approximate gallons per hour of fluid when at full flow. Generally speaking, running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution. Feel free to email us for nozzle advice if your situation is unique.

Optional BMS Elite Steel Braided Hardline Upgrade
This kit includes 18 feet of upgraded stainless steel braided lines. They feature an inner teflon seal for leak free operation, stainless steel braid, and a black outer nylon mesh for abrasion resistance and a stealthy look. These lines not only look great they are also equipped with BMS Elite AN fittings and can withstand extreme pressure and temperature conditions. Includes all required AN fittings. 

1.25 GALLON HEAVY-DUTY UNIVERSAL TANK

The Burger Motorsports 1.25 gallon heavy-duty tank is compact and flexible allowing for a wide range of mounting on any flat vertical surface in the trunk.  

This tank is thicker and stronger than our basic 1-gallon WMI tank. This tank features an easy fill filler nozzle, an anti-starvation reservoir with a pre-threaded bung for the included 90º compression pump feed fitting, a spill-catcher reservoir around the filler cap, a 2-way vented black plastic cap, and is translucent to allow visually checking the fluid level.

Comes with a standard 2 way vented black plastic cap/lid. Upgraded billet cap/lid with 1-way check valve available in the drop-down menu when ordering.

Tank dimensions: L 11" x W 4.5 x H 9"

Applications
Universal trunk mount

2 gallon universal low profile tank

The Burger Motorsports 2 gal. universal tank allows the methanol pump to mount to the bottom of the tank making for a clean and fast installation. It’s universal in nature and will fit a wide variety of trunk applications. The larger capacity means more time between WMI fill ups.  Offered in black and in clear to allow visually checking the fluid level. Includes a 2-way vented black plastic cap and a compression pump feed fitting. Upgraded billet lid with a 1-way check valve available. Comes pre-tapped for the pickup fitting. W  orks with all DDP 5800 pumps. Made in USA.

Tank dimensions: L 15.5" x W 8" x H 8.25"

Applications
Universal trunk mount

BMS 3 gal. STEALTH TANK

BMS Stealth Tank
With our 3 gallon stealth tank the WMI pump mounts directly to the tank and the entire assembly fits cleanly within the existing trunk cavity in your F3X or F8X vehicle below the trunk floor. Works with all DDP 5800 pumps. Made in the USA.

Comes with a standard 2 way vented black plastic cap.
Upgraded billet lid with 1-way check valve available below.

Tank dimensions: L 26.75" x W 9.75" X H 7.5"
