MuchBoost 4.0TDI Upgraded BiTurbochargers with a Custom Billet Compressor Wheel and Clipped/Larger Turbine Wheel. They are based on original Garrett Turbochargers, which means that the installation is 100%P&P. The turbochargers are meant to work with Audi SQ7 4M, Bentley Bentayga, and Porsche Panamera with the 4.0TDI – 416-435HP engine.

The turbo delivers up to 144% power (184 extra HP) over the factory specs. It is a great 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.

We have developed 2 modification options that allow you to reach anywhere from 550HP to 600HP.

MuchBoost 4.0TDI 550

Upgraded turbocharger with an estimated ~550HP at the crank. List of modifications:

  • Upgraded journal bearings system that allows the turbo to hold more boost,
  • More efficient and larger Billet Compressor Wheel,
  • Clipped and Lightened Turbine Wheel,
  • Genuine Garrett compressor housing,
  • Genuine Garrett bearing housing,
  • Genuine Garrett  exhaust manifold,
  • Original actuator,
  • Dynamically balanced,
  • The compressor and turbine wheels are balanced separately, and then the whole core is high-speed balanced using VSR balancing machines at speeds similar to the level seen in the vehicle.
MuchBoost 4.0TDI 600

Upgraded turbocharger with an estimated potential of 600HP at the crank. Modifications compared to the 550 option are the same except:

  • Bigger Compressor Billet Wheel,
  • Larger VNT system,
  • Bigger High-Flow Turbine Wheel.
Other significant modifications

In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.


A set of gaskets is included with every option you choose!
