The F800 is FrankenTurbo's highest-output offering for the E-series N55. It is designed to bridge the gap between a hybrid and a full single-turbo conversion by providing "Big Single" airflow in a package that fits the factory location. This kit is specifically optimized for the E82 and E92 engine bays, ensuring that even with a massive increase in internal wheel size, the turbo maintains proper clearances. It is the definitive choice for the N55 enthusiast chasing 10-second quarter-mile times or extreme roll-racing performance.
Key Features:
Native Twin-Scroll Spool: The stainless steel manifold maintains twin-scroll pulse separation to ensure the 3.0L engine stays responsive during low-RPM transitions.
Ultra-High CFM Throughput: Designed to move enough air to support over 75 lbs/min, allowing for sustained power all the way to the 7,000 RPM redline.
Direct-Fit Infrastructure: Retains compatibility with factory-style oil and coolant lines for a cleaner, more reliable installation.
VSR High-Speed Balancing: Every unit is balanced to a laboratory-grade tolerance on a Vibration Sorting Rig to ensure quiet operation and a long service life.
Optimized Inlet Path: Requires a 2.5" high-flow turbo inlet (sold separately or as an add-on) to feed the high-demand 20G-spec compressor.
Target Fueling: Port Injection (PI) and high-pressure fuel pumps (HPFP) required for maximum potential.
Inlet Requirement: 2.5-inch High-Flow Silicone.
