MuchBoost OM642 Upgraded Turbochargers with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. They are based on original Garrett turbochargers, which means that the installation is 100%P&P. The turbocharger is meant to work with Mercedes Benz 3.0CDI, Jeep Cherokee, and Chrysler with an OM642 190-230HP engine.

The turbo delivers up to 210% power (210 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 350HP to 400HP.

MuchBoost OM642 350

Upgraded turbocharger with an estimated ~350HP at the crank. List of modifications:

  • Precisely machined seal plates and compressor housing,
  • Genuine Garrett  compressor housing,
  • Genuine Garrett bearing housing,
  • Genuine Garrett exhaust manifold,
  • Original Hella actuator
  • More efficient and larger Billet Compressor Wheel GEN II,
  • Enlarged genuine Turbine Wheel,
  • Dynamically balanced,
  • Precisely machined exhaust housing,
  • 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.
MuchBoost OM642 400

Upgraded turbocharger with an estimated potential of ~400HP at the crank. Modifications compared to the 350 option are the same except:

  • Billet Compressor Wheel,
  • Larger High-Flow 9 blades Turbine Wheel.
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.

Example project

One of our clients managed to produce 400/432HP (with WMI) and 889Nm of torque with the turbo. The car, E280CDI W211, was also equipped with:

  • Mishimoto Automotive intercooler 300mm x 650mm,
  • Bigger custom stainless steel Inlet & Outlet pipes,
  • Bigger injectors from 350cdi,
  • Green Filter USA sports filter,
  • Full straight custom stainless steel exhaust system 3,00′,
  • Snow Performance WMI.
