FrankenTurbo F825 Twin-scroll Hybrid Turbocharger - BMW F22/F23 M240i/ix

Product Details

The F825 Hybrid Turbocharger is a precision-engineered forced induction unit designed to optimize the volumetric efficiency of the B58B30M0 engine. This "Stage 3" hybrid addresses the high-RPM backpressure limitations of the factory B58 turbo by significantly increasing the inducer and exducer diameters of the rotating assembly. Through precision CNC-machining of the internal volutes and the use of a mixed-flow turbine design, the F825 reduces exhaust backpressure (PMEP), lowering EGTs and allowing for aggressive ignition timing. Every F825 unit is VSR high-speed balanced to ensure structural integrity at extreme rotational speeds.

Key Features

• VSR High-Speed Balancing: Every assembly is vibration-tested at speeds exceeding 120,000 RPM to ensure OEM-level durability and silence.

• CNC-Ported Manifold: The integrated manifold is internally matched and ported to ensure smooth gas transition into the enlarged turbine housing.

• Inconel 718 Construction: The turbine wheel is cast from a high-nickel alloy, providing superior resistance to thermal fatigue during high-load pulls.

• Optimized Compressor Mapping: The 6+6 billet wheel profile is designed to broaden the efficiency map, preventing surge while maximizing mass airflow.
