Upgrade your 2017–2023 Chevy Silverado or GMC Sierra 2500HD/3500HD 6.6L L5P Duramax with the BD Diesel Screamer Turbo, a drop‑in stock‑appearing turbocharger engineered for more power, cooler EGTs, and factory‑like drivability. BD re‑machines OEM turbo housings to accept a larger 66.2 mm billet compressor wheel and 67 mm turbine wheel, unlocking up to 80 lb/min of airflow and supporting as much as 680 hp when paired with proper fuel, tuning, and supporting modifications.
This L5P Screamer turbo is designed specifically for owners who tow, daily drive, or play on the weekends and want more power without converting to a full custom turbo kit. Because it retains a stock‑style footprint and uses the factory‑style VGT configuration, it bolts in place of the OEM turbo and works with the original intake, exhaust connections, and emissions equipment on applicable trucks. The result is a clean installation that looks nearly OEM under the hood while offering noticeably stronger mid‑range and top‑end performance.
On tuned L5P trucks, the increased compressor and turbine size help the engine move more air with less restriction, reducing exhaust drive pressure and helping keep exhaust gas temperatures in check under heavy load. That makes this turbo an excellent choice for heavy towing, performance street use, or enthusiasts planning future upgrades who do not want to sacrifice spool‑up and low‑rpm response. BD’s high‑quality machining, balancing, and 12‑month/12,000‑mile warranty provide confidence that this turbo will deliver reliable performance mile after mile.
If you’re building a 2017–2023 L5P Duramax and want more airflow and power potential than the stock turbo can offer—without the complexity of a custom kit—the BD Diesel Screamer Turbo is a powerful, direct‑fit solution ready for your Silverado or Sierra HD.
