MuchBoost 3.0BiTDI Upgraded Turbocharger with a Custom Billet Compressor Wheel and Enlarged High Flow 9 blades Turbine Wheel. It is based on an original Garrett Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Audi A6 (C7). A7 (C7), SQ5 (8R) with the DEHA, CVUB, CGQB BiTDI 313-326HP engine.

The turbos deliver up to 159% power (187 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 450HP to 500HP.

MuchBoost CQGB 450

Upgraded turbocharger with an estimated 450HP at the crank. The list of modifications:

Small Turbo

• Refurbished

Big Turbo

• Machined compressor housing,
• Modified seal plate,
• Enlarged Billet Compressor Wheel,
• Lightened GT30 High-Flow Turbine Wheel.
• Fast spool thanks to Custom Billet Compressor Wheel,
• High air-fuel ratio including high peak torque achieved at low engine speed,
• Perfectly calibrated VNT system + dynamically balanced. We use a modern VISCOM flow bench and Schenck balancing machines,
• 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.

Upgraded turbocharger with an estimated potential of 500HP at the crank. Modifications compared to the 450 option are the same, except:

Big Turbo

Other significant modifications

The turbo is meant to work with ~450-500HP In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.
