FrankenTurbo F650 Twin-scroll Hybrid Turbocharger - BMW F3X 335i & 435i

Product Details

The F650 Hybrid Turbocharger is a precision-engineered upgrade that optimizes the volumetric efficiency of the N55B30O0 engine. By increasing the inducer and exducer diameters of both the compressor and turbine wheels, FrankenTurbo has significantly shifted the efficiency map of the turbocharger to support higher mass airflow. This allows for sustained boost levels (up to 26 PSI) without the excessive exhaust backpressure or heat soak common in the stock unit. The F650 is VSR high-speed balanced to ensure structural integrity at rotational speeds exceeding 100,000 RPM.

Key Features

• Mixed-Flow Turbine Technology: The Inconel 718 turbine wheel is designed to reduce backpressure, allowing for increased timing and safer EGTs.

• Ported Volutes: Internal exhaust passages are CNC-machined to match the larger turbine wheel for optimized gas flow.

• VSR Balanced: Every unit is Vibration Sorting Rig (VSR) balanced to tolerances tighter than the original manufacturer’s specifications.

• Optimized Oil/Coolant Passages: Maintains factory thermal management parameters while supporting increased power output.

• Tuning Ready: Calibration-friendly for all major N55 tuning suites, allowing for custom mapping of boost targets and wastegate duty cycles.
