FrankenTurbo F800 Twin-scroll Hybrid Turbocharger - BMW F3X 335i & 435i

Product Details

The F800 Hybrid Turbocharger is a precision-engineered forced induction unit designed for the N55B30O0 engine. This unit addresses the volumetric efficiency limitations of the F3x platform by increasing the flow capacity of both the intake and exhaust sides of the turbocharger. By re-machining the internal volutes of the twin-scroll housing and utilizing a specialized mixed-flow turbine design, the F800 reduces backpressure and exhaust gas temperatures (EGTs). Every F800 unit is VSR high-speed balanced to ensure structural integrity at rotational speeds exceeding 120,000 RPM, providing a reliable, high-output alternative to aftermarket big-turbo kits.

Key Features

• Extended-Tip Billet Technology: The compressor wheel utilizes an aggressive profile to increase airflow efficiency and prevent surge at high pressure ratios.

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

• VSR High-Speed Balanced: Each assembly is vibration-tested to tolerances tighter than OEM requirements for maximum long-term reliability.

• Advanced Metallurgy: Uses an Inconel 718 turbine wheel to handle the extreme heat associated with high-horsepower N55 builds.

• Tuning Versatility: Fully compatible with all major N55 tuning suites, allowing for custom wastegate duty cycle mapping and boost scaling.
