Introduced in 1987, the Detroit Diesel Series 60 performs well in fuel economy tests and is considered one of the most profitable vehicles of its kind. It consistently rates at the top of its category. The six-cylinder engine already produces 425 horsepower, but a few simple modifications can increase that even more.
Upgrade to the latest version of the Detroit Diesel electronic control system. The DDEC (IV) not only allows owners to run diagnostics on the engine, it also allows for changing horsepower settings. Go to your local dealer to have them download the current software to your engine computer.
Replace the factory air filter with a performance version to allow more air to flow through the engine. Change the air filter every few thousand miles anyway, as a clogged filter will decrease its power. You will know you need to change it when it loses the white color it started with and becomes dull.
Install a high flow muffler to allow air to escape freely from the engine. A ported exhaust manifold can increase the power your engine reaches by up to 35 percent.
Invest in high-performance fluids for your engine. Replace standard engine oil and coolant with ones designed to increase your engine’s efficiency.
