The Screamer turbo features a larger billet compressor wheel and a larger high-flow turbine wheel compared to the stock unit. These upgrades increase airflow, support significantly more horsepower, and help lower exhaust gas temperatures (EGTs). — Specifically, the BD Screamer (PN 1045768) is upgraded with a 63mm custom trim Billet Compressor Wheel and a high-flow 67mm turbine wheel. This combination provides a substantial increase in airflow, leading to more boost, lower drive pressures, and decreased peak EGTs—all critical for performance and reliability when towing or daily driving. The turbo comes preset with a BD Wastegate Canister to manage up to 39psi of boost, and with the right supporting modifications, it can help your 5.9L Cummins produce up to 625 horsepower.
