Designed in a joint engineering effort between BD Diesel Performance and BorgWarner Turbo Systems’ AirWerks program, these turbo systems for the 5.9 liter Cummins engine flow enough air for racing applications, yet are responsive and durable enough for street and heavy towing applications. Plus, they’re backed by a one year factory warranty!*
Featuring BorgWarner’s unique Extended Tip compressor wheel technology and low inertia, full-floating journal bearings, these turbos utilize BD’s unique dual-volute turbine housing. This proven design utilizes low rpm exhaust pulses for improved turbine response, while the dual-action waste gate bleeds off turbine drive pressure from both volutes. BD's turbo systems also feature a heavy-duty waste gate actuator that prevents pre-mature opening caused by high exhaust pressure. You can even fine-tune your BD/AirWerks turbo for ambient temperature and barometric pressure changes using BD’s adjustable waste gate control.
Put simply, you'll get more power, quicker response, cooler EGT
