FrankenTurbo F825 Twin-scroll Hybrid Turbocharger - BMW F3X 440i/xi

Product Details

The F825 Hybrid Turbocharger is a precision-engineered forced induction unit designed to maximize the volumetric efficiency of the B58B30M0 engine. This unit addresses the exhaust backpressure limitations of the F3x platform by utilizing a CNC-ported manifold and an enlarged turbine volute. By optimizing the pressure ratio across the turbine, the F825 allows for significantly lower Exhaust Gas Temperatures (EGTs) at high horsepower levels, protecting the engine and turbocharger during sustained high-load applications. Every unit is VSR high-speed balanced to ensure structural integrity at rotational speeds exceeding 120,000 RPM.

Key Features

• VSR High-Speed Balancing: Every rotating assembly undergoes Vibration Sorting Rig testing to tolerances tighter than OEM requirements for maximum longevity.

• High-Silicon Moly Housing: Constructed from premium cast steel to resist cracking and warping under the extreme heat of high-boost B58 builds.

• Inconel 718 Metallurgy: The turbine wheel is cast from Inconel 718, ensuring blade stability and fatigue resistance at temperatures exceeding 900°C.

• CNC Port-Matched Manifold: Internal exhaust passages are machined to ensure smooth gas transition into the enlarged turbine housing.

• Software Versatility: Fully compatible with MHD, Bootmod3, and custom EcuTek maps for comprehensive boost and wastegate management.
