Featuring BorgWarnerƒ??s unique Extended Tip compressor wheel technology and low inertia, full-floating journal bearings, these turbos utilize a dual-volute turbine housing which utilizes low rpm exhaust pulses for improved turbine response, and works great with BD's pulse tuned exhaust manifold. The dual-action waste gate bleeds off turbine drive pressure from both volutes if excessive boost temperatures are experienced. BD's turbo kits also feature a heavy-duty waste gate actuator that prevents pre-mature opening caused by high exhaust turbo drive pressure. You can even fine-tune your BD/AirWerks turbo boost for higher boost if your fueling adjustments exceed 1200 F or barometric pressure changes if operating at high altitude using BDƒ??s adjustable waste gate control Turn Buckle.

The Super B Special bridges the performance gap between the Super B turbo and the Super B twin system. Flowing an amazing 80 lbs. of air per minute (compared to 61 lbs./minute for the Super B), the Super B Special is perfect for late-model Cummins common-rail or modified 12-valve engines and can deliver enough air for 375-525 rear wheel horsepower on diesel only.
