MuchBoost OM642 Upgraded Turbocharger with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. They are based on original Garrett turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Mercedes Benz 3.0CDI with an OM642 265HP engine.

The turbo delivers up to 151% power (135 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 potential ~350HP at the crank. The list of modifications:

• Precisely machined seal plates and compressor housing,
• Genuine Garrett  compressor housing,
• Genuine Garrett bearing housing,
• Genuine Garrett exhaust manifold,
• Genuine Garrett ceramic ball bearings,
• Original Hella actuator,
• More efficient and larger Billet Compressor Wheel GEN II,
  
• Genuine Turbine Wheel,
• Dynamically balanced,
• 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,
• Machined exhaust housing.

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 make 359HP and 750Nm of torque with the OM642 350 turbo. The car was stock, except for the ECU tune. Please take a look at the dyno graph below.

A set of gaskets is included with every option you choose!
