The BD-Power 1045310 Super "B" Twin Turbo Kit 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. 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.
BD’s 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 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.
Note: This Upgrade kit only includes 1 turbocharger and will convert your current setup into the "Towing Twins". YOU MUST already have a Super B Single Turbocharger to complete this system. Exhaust Manifold not included.
We recommend that applications with twin turbos utilize one of our Cool-It Intercoolers – only BD Charge Air Coolers are designed to handle the flow and boost pressure created with these fueling and turbo combinations.
We suggest tuning your fueling program to not exceed 1200 degrees F when working your engine hard with whatever turbo combination you have. Adjusting your waste gate closed for higher boost pressure provides more air and cooler exhaust gas temperatures. Extreme high exhaust gas temperatures will cause head gasket problems among many other problems. Turbos need exhaust temperatures to develop boost but temperatures above 1200 F reflect not enough air for the amount of fuel injected. Stock intake filters will not handle twin turbo air needs.
