MuchBoost CDSB 4.2TDI hybrid turbo set, Audi A8 D3 4.2TDI (500–570 hp)

MuchBoost CDSB 4.2TDI hybrid turbo set, Audi A8 D3 4.2TDI, 500–570 hp

A bolt-on MuchBoost hybrid turbo set for applications including Audi A8 D3 4.2TDI, Audi Q7 4.2TDI. This upgrade is built for CDSB 4.2TDI 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 500–570 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.
