More power, quicker spool and 50-state legal.

The BD Diesel Screamer Stage 1 GT37 is a direct drop-in performance turbo for 2003–2007 Ford F-250 and F-350 6.0L Powerstroke trucks. It carries CARB Executive Order D-553-28, making it legal for sale and use in all 50 states, including California. You get better airflow, quicker spool-up and up to 425 hp without worrying about emissions inspections.

Built for towing and daily driving.

Designed with towing, daily driving and mild performance in mind, the Stage 1 Screamer uses a larger billet compressor wheel and an upgraded turbine. It improves throttle response and top-end performance without sacrificing low-end torque.

Engineered for efficiency.

A 13-blade turbine wheel with taller vanes is designed for quicker spool-up than competing turbos. BD technology keeps the exhaust vanes operating in their most efficient range to maintain boost and improve turbine performance.

What Problem Does This Solve?

• Emissions-legal performance options are hard to find. Many performance turbos can't be legally sold or installed in California and other states with strict emissions rules. The Screamer Stage 1 carries a CARB EO number, so you can upgrade legally and pass inspections.
• A worn-out stock turbo. If your factory turbo is failing, the Screamer Stage 1 replaces it with a stronger, more responsive unit in the same factory location.
• Losing low-end response with a bigger turbo. Many performance turbos trade off-the-line response for top-end power. The 13-blade turbine is designed for quick spool, keeping the truck responsive for towing and daily driving.

Is This Turbo Right for You?

The Screamer Stage 1 is ideal for owners who want a legal, drop-in performance upgrade, especially in California or other CARB-regulated states. It's well suited to stock-injector trucks used for towing, daily driving and mild performance. If emissions compliance isn't a concern and you're running performance injectors, the BD Screamer Stage 2 (1045821) offers more airflow.
