BD Diesel 1045844 Screamer Turbo for Select 2017-2023 Chevy/GMC 2500/3500 HD (6.6L)

Fits select 2017-2023 Chevrolet Silverado and GMC Sierra 2500/3500 HD (6.6L Duramax L5P).

The BD Diesel Screamer Turbo is a high-performance, drop-in replacement designed for the L5P Duramax platform. Engineered to appear stock while delivering significantly improved airflow, this turbocharger is a true bolt-on upgrade that maintains compatibility with factory emissions equipment and does not require custom tuning or set engine codes. It utilizes a custom Mixed Flow Turbine (MFT) wheel with a 65mm exducer to reduce drive pressure and lower exhaust gas temperatures (EGTs) without sacrificing low-end responsiveness.

Equipped with a larger 66.2mm (and 64.0mm) billet compressor wheel, the Screamer increases airflow up to 80 lb/min, supporting up to 680 horsepower with the right supporting modifications. The larger 67mm turbine wheel ensures efficient exhaust flow, allowing for more boost and lower EGTs even at increased power levels. This kit includes a high-flow intake horn to maximize intake efficiency from the start.
