MuchBoost 5.0TFSI 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 C6 with the BUH 580HP engine.

The turbos deliver up to 155% of stock power (320HP 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 5.0TFSI BUH 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,
• Enlarged and Lightened High-Flow 8 blade Turbine Wheel,
• Genuine IHI compressor housing,
• Genuine IHI exhaust manifold,
• Genuine IHI bearing housing,
• Precisely machined exhaust manifold,
• 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 5.0TFSI BUH 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,
• Reinforced actuator.

Other significant modifications

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