BD Power 98.5-02 5.9L 24 Valve Ram Super B Twin Turbo (Upgrade)

TWIN TURBO SYSTEMS

Super B Twin: Designed for high-powered ’94-‘06 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 to 800+! Great street and strip driveability, easy installation, and the factory oil coolers can be retained.

1989-1993 Cummins 5.9 engines have a variety of large turbine housings that all result in a large turbo lag before boost is developed. The above years will benefit by changing to a 16 sq cm housing to a non-waste gated turbine housing part #1045910 on stock or engines that have had high flow injectors installed

1994-1999 stock engines have the 12 sq cm w/g hsg that can be quite restrictive when the power is increased above 300 flywheel HP and results in high exhaust temperature.

2001 automatic transmission equipped engines have a 9 or 10 sq cm hsg that is too restrictive for a high power increase (beyond the 300 hp)

2003 and 04 Super B kits include an adapter so the turbo mount exhaust brake can bolt up; later models require a remote mount exhaust brake. 2003-04 Engines that have any more than a 100 hp increase will cause the stock turbo to over speed, surge and fail.

Designed in a joint engineering effort between BD Diesel Performance and Borg Warner Turbo Systems’ AirWerks program, these new 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!*

Turbocharger lag is usually the result of an improperly matched turbocharger. As the compressor wheel size is increased to meet the airflow requirements of the engine, it gets heavier, which hurts response time. BD’s turbo systems, using Borg Warners’ unique Extended Tip compressor wheel technology and low inertia, full-floating journal bearings, outperforms ball bearing turbochargers of a similar size.

Our unique dual-volute turbine housing picks up 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 barametric 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.
