Description
Unlock race-gas performance using pump fuel with the Burger Tuning JB4 Universal Water/Methanol Injection (WMI) Kit. This system delivers the cooling and detonation resistance of 100+ octane fuel or E85, allowing for higher boost targets, improved ignition timing, and significant power gains — all while maintaining safety and reliability.
The heart of the system is the Burger Motorsports JB4 FSB WMI Controller, which enables full JB4 tuning system integration. Unlike generic WMI setups, this controller offers dynamic progressive flow control, allowing real-time mapping based on boost, throttle position, engine RPM, intake temperature, gear, ignition advance, and more using the JB4’s CANbus data feed.
The system continuously monitors pump current and includes a built-in flow-based safety feature. If methanol flow drops or the tank runs dry, the JB4 will automatically reduce boost and adjust tuning parameters to protect the engine. Flow status and activation are fully visible through the JB4 Mobile app or in-dash display, with WMI activation/deactivation available from the driver’s seat.
Included in the base kit is a 220psi Aquatec pump, a methanol-rated solenoid with built-in filter, 20 feet of durable WMI line, a compression fitting set for leak-free operation, and complete wiring. You can further customize the system with your choice of nozzles, tanks, and an optional steel braided line upgrade for high-pressure/high-temperature environments.

Nozzle Recommendations
Choose based on engine and boost setup:
- 4-cylinder setups: BM7
- 6-cylinder setups: BM10 or Dual BM5
- 8-cylinder setups: Dual BM5 or BM10 for high-boost/large turbo setups
Note: Two smaller nozzles typically offer better atomization than one large nozzle.
