FrankenTurbo F650 Twin-scroll Hybrid Turbocharger - BMW F07/F10/F11 535i

Product Details

The F650 Hybrid Turbocharger is a performance-optimized rotating assembly designed for the N55B30O0 engine. The unit addresses the high-RPM "choke point" of the factory turbo by increasing the inducer and exducer diameters of both the compressor and turbine wheels. By optimizing the internal volutes and utilizing a mixed-flow turbine design, the F650 significantly reduces exhaust backpressure, leading to lower EGTs (Exhaust Gas Temperatures) and increased reliability under sustained load. Every unit is VSR high-speed balanced to ensure structural integrity at speeds exceeding 110,000 RPM.

Key Features

• Point-Milled Billet Technology: The compressor wheel utilizes extended-tip technology to broaden the efficiency map and prevent surging.

• CNC-Ported Exhaust Manifold: The integrated manifold is internally machined to match the higher flow capacity of the larger turbine.

• VSR Balanced: Every turbocharger undergoes Vibration Sorting Rig balancing to ensure OEM-level NVH (Noise, Vibration, and Harshness) levels.

• Advanced Thermal Management: The Inconel 718 turbine wheel is rated for high-heat environments common in tuned N55 applications.

• Tuning Versatility: Fully compatible with MHD, Bootmod3, and custom COBB Pro-tunes.
