The BD Diesel Screamer turbocharger is a drop-in replacement designed for 2004.5-2010 Chevrolet and GMC Duramax diesel trucks (LLY, LBZ, and LMM engine codes). This turbocharger utilizes modern technology to enhance engine performance while maintaining factory-like spool-up characteristics.
Key Features:
- 65mm Billet Compressor Wheel: This upgraded compressor wheel is designed to deliver increased airflow to the engine.
- Mixed Flow Turbine Wheel: Incorporating new technology, the larger turbine wheel improves overall turbo flow and efficiency.
- Increased Airflow: Capable of supporting up to 85 lb/min of airflow for enhanced engine output.
- Improved Performance: Expect increased boost pressure, lower exhaust gas temperatures (EGTs), and reduced drive pressure.
- Stock-Like Spool-Up: The Screamer turbo spools similarly to the original Duramax LBZ turbo, preserving low-end responsiveness.
- Power Potential: This turbocharger can support a suggested maximum of 690 crank horsepower.
- Balanced: Each turbocharger undergoes VSR high-speed balancing for optimal performance and reliability.
- 50 State Legal: Designed to meet emissions standards in all 50 states.
- Compatibility: Works with most "box" tuners, with further gains achievable through custom tuning.
- Note for LLY Engines: Installation on 2004.5-2005 LLY Duramax engines requires adapter part number 771864-0001 (sold separately).
