Engineered specifically for 2003 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Excursion trucks equipped with the 6.0L Powerstroke diesel engine, the BD Diesel Screamer Stage 1 GT37 Performance Turbocharger (1045820) offers a direct bolt-on upgrade that maintains an OEM stock exterior appearance while substantially boosting airflow. Many aftermarket performance turbos create excessive low-end lag that compromises towing; the Screamer Stage 1 is tailored specifically for stock to mild fuel injectors to ensure quick off-the-line spool-up, reduced exhaust gas temperatures (EGTs), and dependable heavy-towing capability.

At the core of the Screamer Stage 1 is a custom-machined 6x6-blade 61.4mm inducer billet compressor wheel paired with an 82mm exducer featuring 88mm extended-tip technology. It is driven by an oversized 72.5mm / 66.45mm 10-blade turbine wheel equipped with taller vanes. This turbine configuration lowers drive pressure and backpressure across the variable vanes while producing the classic, aggressive 6.0L exhaust whistle. Each unit is precision VSR high-speed balanced and ships complete with the required hardware to securely bolt to both early and late engine mounting pedestals.

Key Features & Benefits

• Billet Extended-Tip Compressor Wheel: 61.4mm inducer and 82mm exducer with 88mm extended tips deliver up to 425 RWHP and out-flows the Garrett PowerMax on stock fueling.
• 10-Blade High-Flow Turbine Wheel: Features taller vanes and a 66.45mm exducer that broadens top-end exhaust flow while producing the signature, aggressive turbo whistle.
• Quick-Spooling Tow-Friendly Profile: Engineered to spool instantly from low RPMs with stock injectors, preventing smoke output and high towing EGTs.
• Enhanced Anti-Surge Compressor Cover: Precision-machined ported shroud combats compressor surge when hauling heavy payloads through steep grades.
• Stock Appearance & Direct Fitment: Retains a completely stock exterior profile while including adapter hardware to utilize all three factory pedestal mounting locations.
• Broad Tuning Compatibility: Runs cleanly on stock engine calibrations and pairs seamlessly with aftermarket tuners such as SCT, Bully Dog, and H&S.
