Water/Methanol Injection (WMI) nozzles are determined by the intended power and how many bungs your charge pipe has. The nozzles are 1/8” NPT and screw in to bungs included on most aftermarket charge pipes. Our "super atomizing" nozzles are designed and manufactured by us and are known for their great atomization and flow characteristics. The number on the methanol injection nozzle 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.

Below are some general nozzle suggestions but feel free to email us for nozzle advice if your situation is unique.

Water Methanol Injection Nozzle Flow Rates:

Methanol Injection Nozzles are rated in ( GPH) gallons per hour using a BMS WMI pump @ 200psi

BM5: 5 GPH = 315 ml/min
BM7: 7 GPH = 440 ml/min
BM10: 10 GPH = 630 ml/min
BM12: 12 GPH = 750 ml/min
BM14: 14 GPH = 880 ml/min
