MuchBoost 2.0TDI CAGA/CAGB/CAGC Upgraded Turbocharger with a Custom Billet Compressor Wheel 6+6 Blades. It is based on an original MHI Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Audi vehicles with the CAGA, CAGB, CAGC 120-140HP engines.

The turbo delivers up to 191% power (110 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.

Main Features
  • The potential 220-230HP,
  • Fast spool thanks to Custom Billet Compressor Wheel 6+6 Blades,
  • Clipped and Lightened Genuine Turbine Wheel,
  • High air-fuel ratio including high peak torque achieved at low engine speeds.
Details on the construction of the turbo:
  • Machined genuine KKK compressor housing,
  • Genuine KKK exhaust manifold,
  • Genuine KKK bearing housing,
  • Original KKK electronic actuator,
  • Only oil cooling,
  • Modified seal plate,
  • Upgraded Journal bearing system that allows holding more boost,
  • 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.
Other significant modifications

The turbo is meant to work with ~230HP In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.
