Mercedes E280 CDI W211 OM642 Build Reaches 400 HP and 432 HP With WMI

Diesel performance projects continue to surprise people, and this Mercedes-Benz E280 CDI W211 is a perfect example. Built by Maxi-Chiptuning, this OM642-powered car reached 400 HP, and with WMI the figure climbed to 432 HP.

That means roughly 100 percent more power than the stock version, turning a refined diesel sedan into something that can genuinely shock other drivers from the traffic lights.

OM642 Performance Potential Is Much Bigger Than Most People Expect

The OM642 engine has always been a strong and capable platform, but in factory form, its full potential remains untapped. With the right turbocharger and supporting setup, it can become an entirely different machine.

In this project, the car was equipped with a substantial list of supporting modifications, including a Mishimoto intercooler measuring 300 mm by 650 mm, larger custom stainless steel inlet and outlet pipes, bigger injectors from the 350 CDI, a Green Filter sports filter, a full straight custom 3-inch stainless steel exhaust system, and a Snow Performance WMI setup.

All of these upgrades were chosen to support increased airflow, better cooling, and the fueling required for serious diesel performance.

MuchBoost OM642 400 Upgraded Turbocharger

At the heart of the build is the MuchBoost OM642 400 Upgraded Turbocharger. This unit was developed for drivers who want to go far beyond stock output while keeping the OM642 platform responsive and effective under demanding conditions.

A turbocharger upgrade on a diesel engine is not just about more power. It is also about improving the engine’s overall efficiency under load and making the most of the supporting modifications around it. In this build, the results show just how effective that combination can be.

400 HP Baseline and 432 HP With WMI

The numbers here are exceptional for a road-going diesel Mercedes. Reaching 400 HP already puts this W211 in a completely different league from the stock car. Pushing to 432 HP with WMI takes it even further and shows how much potential exists when the setup is properly developed.

It is not only a matter of headline power figures. With this kind of output, the car delivers far stronger acceleration and a driving experience that is dramatically more aggressive than what most people expect from an E-Class diesel.

A Great Example of Diesel Tuning Done Right

This project by Maxi-Chiptuning is a very good example of what happens when a diesel platform is built properly. The hardware list is well thought out, the turbo choice is correct for the goal, and the final numbers confirm that the result is not theoretical. It works.

If you are looking for specialists experienced with OM642 builds, this project makes a strong case for the team behind it.

Take Your OM642 Further With MuchBoost

For Mercedes owners running the OM642 engine and looking for a serious step forward, the MuchBoost OM642 400 Upgraded Turbocharger is a proven solution. Whether your goal is stronger street performance or a full performance-oriented diesel build, this platform has far more to offer than most people assume.
