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

’s and lower exhaust emissions with a BD/AirWerks turbocharger! And, you’ll have the added benefit of proven journal bearing technology--the very same used in 99% of the turbochargers produced in the world since 1921.

TWIN TURBO SYSTEMS are designed for high-powered ‘94-‘07 5.9 liter Cummins applications without cylinder head modifications, the Super B twin can easily flow enough air for up to 575 rwhp

on diesel only. Add a BD Cool-It intercooler and a shot of nitrous oxide, and watch the power level climb! Great street and strip driveability, easy installation, and the factory oil coolers can be retained.
