UNDER THE HOOD: Diesel Engine Lifehacks for Better Performance

Mechanic at workIn this age of Youtube tutorials and gearhead online forums, we have seen a huge increase in casual consumers and hobbyists looking to take their diesel engines to the next level. But with so many options out there, how do you identify the most cost-effective and mechanically sound upgrades to make? Read on for EngineTech’s top upgrades, modifications and best practices to get the most out of your diesel engine, while maintaining its efficiency and your safety.

DON’T TUNE OUT, TUNE UP!

With so many electric sensors and warning lights in modern diesel technology, it is easy to become complacent about regular engine maintenance. But despite all of the advances, the absolute best way to ensure your diesel engine never loses power is to keep it up to date on a consistent schedules of oil changes, tune ups and other minor, preventative maintenance. This will reduce repair costs down the road and keep your engine running at optimum efficiency for years to come.

INJECT SOME PERFORMANCE ENHANCEMENT

Consumer-level diesel engines often come with parts that are cheap and easy to replace in order to reduce overall cost and hassle to the customer. Of course there are hyper-efficient, custom parts available for the aftermarket crowd. While expensive and often more difficult to find, high-end fuel injectors are one of the simplest ways to increase the horsepower output of a diesel engine. Claims range from a 50 to 100hp increase, but results vary between manufacturers.

EXHAUSTIVE RESEARCH

An internal combustion engine’s exhaust system is designed to move emissions and, just as importantly, heat away from the source. Improved heat distribution often leads to an increase in horsepower, so consider upgrading to straighter, larger diameter exhaust systems appropriate to the size of your engine (going too big can reduce power). When combined with a cold-air intake, your diesel engine’s overall performance will increase with a noticeable boost to its horsepower.

HACK THE MAINFRAME

All modern diesel engines are monitored and adjusted by an electrical brain located in a tiny computer chip. This chip contains all the information for how the engine performs and how it responds to user input. Replacing this chip with one that is programmed for increased power or torque is one of the most cost-effective ways to increase an engine’s performance.

SECRET INGREDIENTS

You’ve seen them on the shelves: little bottles with brightly coloured labels claiming increased power when added to your diesel engine’s fuel system. These additives can temporarily provide a slight boost to horsepower, torque or acceleration– but overuse or reliance on these substances can harm the designed balance of your engine.

The above adjustments and upgrades are done at your own risk, so please consult with our experts or your diesel engine’s manufacturer before making a change that affect your product’s efficiency or lifespan.
