BD Diesel Duramax Screamer Turbo - 2004.5-2010 Chevrolet LLY/LBZ/LMM

If you're looking to get more out of your 2004.5-2010 Duramax diesel, the BD Diesel Screamer Turbo is a solid option. This turbocharger is designed as a direct replacement for your stock unit, fitting in a range of Chevrolet and GMC trucks like the Silverado 2500 HD, Sierra 2500 HD, and Express 2500 vans. It uses modern mixed-flow technology to increase airflow without sacrificing the low-end response you need for daily driving.

What sets this turbo apart is its 65mm billet compressor wheel and larger turbine wheel, which work together to boost airflow and efficiency. This means you can achieve higher horsepower potential, and tests have shown it can lead to increased power output while actually lowering peak Exhaust Gas Temperatures (EGTs) when paired with the right tune. It's designed to spool up similarly to an OEM LBZ turbo, so you won't experience excessive lag. This turbo is capable of supporting up to an estimated 690 crank horsepower and can handle up to 85 lbs/min of airflow, making it a significant upgrade over stock and even outperforming some aftermarket options like the Garrett Powermax Stage 1.

The Screamer turbo is compatible with most 'box' tuners, but you'll see even greater improvements with custom tuning. It's a VSR high-speed balanced unit, ensuring smooth operation and durability. If you're aiming for more power and better performance from your Duramax, this turbocharger is a well-built choice that offers a noticeable improvement.
