MuchBoost 9A1 Upgraded Turbochargers with a Custom Billet Compressor Wheel and Clipped and Lightened/Enlarged Turbine Wheel. They are based on the original BorgWarner Turbochargers, which means that the installation is 100%P&P. The turbochargers are meant to work with Porsche 911 Turbo S 991 with the 9A1 520-560HP engines.

The turbo delivers up to 182% power (430 extra HP) over the factory specs. It is an excellent choice for someone looking for a bit extra HP from their daily driver. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.
