MuchBoost EA111 Upgraded Turbocharger with a Custom Billet Compressor Wheel and a Clipped and Lightened Turbine Wheel. It is based on an original Mitsubishi Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Audi A3 8P, VW Golf VI, Seat Leon, Skoda Octavia, and others with the EA111 122HP engines.

The turbo delivers up to 204% power (128 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 3 modification options that allow you to reach anywhere from 210HP to 250HP.

MuchBoost EA111 210

Upgraded turbocharger with an estimated ~210HP at the crank. List of modifications:

  • Upgraded journal bearings system that allows the turbo to hold more boost,
  • Genuine actuator
  • More efficient and larger Billet Compressor Wheel,
  • Genuine Clipped and Lightened Turbine Wheel,
  • Genuine Mitsubishi compressor housing,
  • Genuine Mitsubishi bearing housing,
  • Genuine Mitsubishi exhaust manifold,
  • 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.
MuchBoost EA111 230

Upgraded turbocharger with an estimated potential of ~230HP at the crank. Modifications compared to the 210 option are the same except:

  • Bigger Compressor Billet Wheel,
  • Bigger Turbine Wheel,
  • Precisely machined exhaust housing.
MuchBoost EA111 250

Upgraded turbocharger with an estimated potential of ~250HP at the crank. Modifications compared to the 230 option are the same except:

  • Bigger Compressor Billet Wheel,
  • High-Flow 9 Blades Turbine Wheel.
Other significant modifications

The turbo is meant to work with ~220-250HP In order to reach that level of power, you need to adjust your fuel, exhaust, intake, and cooling systems as well. For this turbo to work correctly you will also need to get an EBC (external boost controller) installed. 

Example project

A great example of our turbo at work is a VW Jetta with 204HP and 328Nm of torque. Dyno graph below.

Another example with our turbo managed to achieve 158HP and 260Nm of torque at the wheels. Dyno graph below:

Again, one of our clients, with the 210 HP option, managed to produce 164 HP at the wheels and 260 Nm of torque. The car was also equipped with:

  • AVP Motorsport More-BHP ECU 3_95Ron
  • AVP Motorsport More-BHP TCU 3
