MuchBoost ASE W18 4.0 TDI hybrid turbo set, Audi A8 D3 4.0TDI (440–480 hp)

MuchBoost ASE W18 4.0 TDI hybrid turbo set, Audi A8 D3 4.0TDI, 440–480 hp

A bolt-on MuchBoost hybrid turbo set for applications including Audi A8 D3 4.0TDI. This upgrade is built for ASE W18 4.0 TDI 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 440–480 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.
