MuchBoost 9A1 Porsche hybrid turbo, Porsche 911 GT2 RS 991/991.2 (750 hp)

MuchBoost 9A1 Porsche hybrid turbo, Porsche 911 GT2 RS 991/991.2, 750 hp

A bolt-on MuchBoost hybrid turbo for applications including Porsche 911 GT2 RS 991/991.2, Porsche 911 Turbo S 991. This upgrade is built for 9A1 Porsche 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 750 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.

Upgrade service or a complete new turbo?

You can order the turbo either by sending your original unit to us as the build core or by choosing a complete, newly built turbo.

Send my original turbo: The serviceable original housings are used to build the new hybrid turbo. After ordering, we will email the return instructions so the turbo can be sent through us for the upgrade. The work and delivery normally take around 2–3 weeks from the time the turbo arrives for inspection. The supplied unit must be original and its housings must be serviceable.

Complete new turbo: You receive a complete, ready-built hybrid turbo. Your original unit does not need to be sent in, so it can be retained or sold separately.
