Over the past ten to fifteen years, diesel engines and the vehicles they power have grown exponentially in popularity. Why is that? And how can you make your diesel truck more powerful and fuel efficient with performance upgrades?

Diesel Performance

The most popular diesel performance Willys Workshop involve modifying the turbocharger(s), fuel injection, and camshaft. These diesel engine upgrades can increase airflow, reduce exhaust back pressure, and boost horsepower and torque. The best diesel performance parts are designed to help your diesel engine operate at peak efficiency with the least amount of emissions.

Turbochargers are a great way to get more power out of your diesel engine because they force more air into the combustion chamber, allowing for a higher compression ratio and greater cylinder horsepower and torque. A basic turbo can improve engine power by four times that of a naturally aspirated (NA) diesel.

Diesel Performance for Beginners: Where to Start Your Upgrades

Diesel fuel injectors provide the right air/fuel mixture for your diesel engine to perform at its best. They are also designed to reduce the build-up of deposits and to protect fuel pumps and injectors from wear.

Camshaft

Many diesel specialists agree that the key to a big performance gain in a stock diesel engine is not necessarily revving the engine higher, but optimizing the boost supplied by the turbo with the right sized camshaft. Camshafts with asymmetrical profiles for the intake and exhaust valve lobes can deliver a much broader and fatter power band than traditional flat tappet camshafts with flat bottom lifters.
