MuchBoost BV50 hybrid turbo, Audi A4 3.0TDI B7 (330–470 hp)

MuchBoost BV50 hybrid turbo, Audi A4 3.0TDI B7, 330–470 hp

A bolt-on MuchBoost hybrid turbo for applications including Audi A4 3.0TDI B7, Audi A6 3.0TDI C6. This upgrade is built for BV50 applications and retains a clean, vehicle-specific installation.

The turbo is based on original Garrett 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 330–470 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.
