BD Diesel Screamer Stage 2 GT37 turbo — drop-in replacement for 2003–2007 Ford 6.0L platforms. Stage 2 uses a billet 11-blade compressor (around 63mm inducer/88mm exducer) and a 10-blade turbine profile to boost airflow and turbine efficiency; it outperforms competing Powermax units in BD's testing. This larger stage is intended for builds with higher-flow injectors and can produce substantially more power when paired with supporting fueling and tuning.
