Screamer Turbo 66.2mm Compressor 67mm Turbine

The BD Diesel 1045844 Screamer Turbo is designed to enhance the performance of 2017-2023 GM Silverado/Sierra 2500HD/3500HD models equipped with the 6.6L Duramax L5P engine. This turbocharger features custom compressor and turbine wheels, including a larger 66.2mm billet compressor wheel and a 67mm turbine wheel, which are engineered to provide increased airflow up to 80 lb/min without compromising low-end performance. Manufactured using OEM housings, the Screamer Turbo is machined to accept these larger wheels, leading to improved airflow and lower exhaust gas temperatures (EGTs), particularly at increased power outputs. It is designed as a stock-appearing, drop-in replacement that maintains compatibility with the factory emissions system. The turbo includes an intake horn, and installation is estimated to take approximately 10 hours. With supporting modifications such as custom tuning and fuel upgrades, the BD Diesel 1045844 Screamer Turbo can support up to 680 horsepower. It is recommended to use custom tuning to maximize efficiency and performance with this turbo. While it works with stock emissions, it is noted that this product is not legal for use on registered California vehicles. The turbocharger comes with a 12-month, 12,000-mile warranty that covers parts only. A $300 core charge is required, which is refundable upon the return of the original core. Buyers should be aware that this is a large, heavy unit, and higher shipping or freight costs may apply.
