MuchBoost 2.5 TFSI CEPA Upgraded Turbocharger with a Custom 6+6 blades Billet Compressor Wheel and an Enlarged KKK K24 or 9 blade Turbine Wheel. It is based on an original KKK turbocharger. The turbocharger is meant to work with Audi RS3 8PA, 8V, TTRS 8J, RSQ3 8U equipped with the 2.5TFSI CEPA/CEPB/CZGB 340-367HP engine.

The turbo delivers up to 161% (210HP extra) over the factory specs. It is a great choice for someone looking for a more sporty feel and more power. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.

The turbo delivers up to 550HP which means it could be perfect for a faster daily driver, to gain some additional power.

Main features
  • The potential 550HP,
  • Low manifold pressures at high RPM,
  • High air-fuel ratio including high peak torque achieved at low engine speeds,
  • Upgraded journal bearings system that allows the turbo to hold more boost.
Details on the construction of the turbo:
  • Custom Billet Compressor Wheel 6+6 Blades,
  • Enlarged Turbine Wheel KKK K24 or 9 Blades one,
  • Precisely machined exhaust housing,
  • Genuine Modified KKK compressor housing,
  • Genuine KKK bearing housing,
  • Genuine KKK exhaust manifold,
  • Reinforced actuator,
  • Enlarged Billet Compressor Wheel,
  • 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.

9 Blades Turbine Wheel provides a better spool, while the K24 Wheel allows for better top-end performance. 

Other Significant Modifications

To fully utilize the potential of this hybrid turbo, we recommend upgrading i.a. fuel, exhaust, cooling systems, and the clutch. Individual ECU remapping is the foundation.

The one thing required to fit this turbo is a modification of The Inlet Pipe.

Example project:

One of our clients managed to produce 427HP at the wheels and 740Nm with our turbo. Dyno graph below:
