MuchBoost 2.7 Bi-Turbo hybrid turbo set, Audi RS4 B5, 610 hp

A bolt-on MuchBoost hybrid turbo set for applications including Audi RS4 B5, Audi S4 B5. This upgrade is built for 2.7 Bi-Turbo applications and retains a clean, vehicle-specific installation.

The turbo is based on original BorgWarner housings. The upgraded compressor and higher-flow turbine sides provide considerably more capacity than the factory unit, while the housings are precision-machined for the new internals.

Depending on the selected version, the manufacturer rates the turbo for approximately 610 hp. Final output depends on engine condition, the fuel system, intake, exhaust, cooling and, above all, the ECU calibration.

An upgraded turbo always requires vehicle-specific ECU calibration.
