The Mercedes-Benz OM605 diesel engine is a favorite among diesel enthusiasts for its reliability, durability, and smooth performance. However, like many stock engines, it has limits when it comes to producing higher power, especially for turbocharged or high-boost applications. One of the most effective ways to unlock more power and efficiency is by upgrading or optimizing your OM605 Mechanical Injection Pump. At Benz Injection, we provide high-quality pumps designed to improve performance while maintaining engine reliability.
Stock OM605 mechanical injection pumps are designed for fuel efficiency and long-term reliability, not maximum horsepower. When you push your engine with a larger turbo, higher boost, or additional modifications, the stock pump may not deliver fuel efficiently. Common problems include:
Sluggish throttle response
Uneven fuel delivery
Limited top-end horsepower
Increased smoke under heavy load
These limitations can make your engine feel sluggish and prevent it from reaching its full potential.
Upgrading to a performance OM605 Mechanical Injection Pump ensures more precise fuel delivery. By providing the right amount of fuel at the right time, the engine can burn fuel more efficiently. This results in:
Increased horsepower across the RPM range
Smoother acceleration
Better throttle response
Improved overall engine efficiency
Performance pumps are calibrated to work well under higher boost levels, making them ideal for turbo diesel builds.
One of the key benefits of a properly upgraded OM605 Mechanical Injection Pump is better fuel atomization. Atomized fuel mixes more completely with air in the combustion chamber, leading to faster and cleaner combustion. This not only increases power but also reduces smoke and improves fuel efficiency.
Better combustion also helps maintain lower exhaust gas temperatures, which is critical for engine safety and longevity when running performance setups.
A high-quality OM605 Mechanical Injection Pump from Benz Injection is designed to handle increased fuel pressure and boost without compromising reliability. These pumps are built with precision components and are flow-tested to ensure consistent performance. Unlike cheap aftermarket alternatives, they provide long-term durability and protect critical engine components like injectors and fuel lines from damage caused by inconsistent fuel delivery.
Installing a performance OM605 Mechanical Injection Pump is straightforward with proper guidance. While most skilled mechanics or experienced enthusiasts can handle installation, it’s important to follow calibration and timing procedures to maximize performance gains. Regular maintenance, such as keeping the fuel clean and checking pump timing, ensures your engine continues to perform at its best for years.
Whether you are running a daily driver, a turbo diesel project, or a high-boost performance build, upgrading your OM605 Mechanical Injection Pump is a reliable way to increase power. It is particularly beneficial for:
Turbocharged OM605 engines
Diesel engines with modified fuel systems
Performance builds that require precise fuel delivery
Increasing power on your OM605 diesel engine doesn’t always mean heavy modifications. By upgrading to a performance OM605 Mechanical Injection Pump from Benz Injection, you can achieve smoother throttle response, more horsepower, and reliable fuel delivery. This simple yet effective upgrade ensures your diesel engine runs efficiently, safely, and at its full potential.
