MuchBoost 4.0TFSI Upgraded Turbochargers with Enlarged Billet Compressor Wheels and Enlarged Turbine Wheels. They are based on genuine IHI turbochargers, which means that the installation is 100% P&P. The turbochargers are meant to work with Audi RS6 C7, Audi S8 PlusD4, Bentley Continental GT III with the 4.0TFSI 560-605HP engine.

The turbos deliver up to 160% of stock power (340HP extra) which means it could be perfect for a faster daily driver, to gain some additional power.

We have developed 2 modification options that allow you to reach anywhere from 800HP to 900HP.

MuchBoost 4.0TFSI 800

Upgraded turbochargers with an estimated ~800HP at the crank. List of modifications:

  • Precisely machined seal plates and compressor housing,
  • More efficient and larger Billet Compressor Wheel 6+6 blades,
  • Upgraded journal bearing system that allows the turbo to hold more boost,
  • Clipped and Lightened Turbine Wheel,
  • Genuine IHI compressor housing,
  • Genuine IHI exhaust manifold,
  • Genuine IHI bearing housing,
  • Original IHI actuator,
  • 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 4.0TFSI 900

Upgraded turbochargers with an estimated potential of ~900HP at the crank. Modifications compared to the 800 option are the same except:

  • Enlarged Compressor Billet Wheel,
  • Larger Turbine Wheel,
  • Precisely machined exhaust housing.
Other significant modifications

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