If you’re a fan of diesel engines, you’ve probably heard of the Cummins 4BT. This engine is known for its reliability, durability, and most importantly, its horsepower. In this article, we’ll take a closer look at the Cummins 4BT horsepower, its specs, and how it compares to other engines in its class.
What is the Cummins 4BT Engine?
The Cummins 4BT is a 3.9-liter, four-cylinder diesel engine that was first introduced in the late 1980s. It was primarily used in industrial applications, such as generators, construction equipment, and marine vessels. However, it also gained popularity as a conversion engine for light and medium-duty trucks.
Cummins 4BT Horsepower and Torque
One of the selling points of the Cummins 4BT is its impressive horsepower and torque. The engine is capable of producing up to 170 horsepower and 420 lb-ft of torque, which is impressive for a four-cylinder engine. This makes it a popular choice for those looking to upgrade the power of their vehicles.
Cummins 4BT vs. Other Engines
When it comes to comparing the Cummins 4BT to other engines in its class, the most common comparison is with the Cummins 6BT. The 6BT is a larger engine that is also known for its reliability and durability. However, the 4BT is often preferred for its smaller size and better fuel efficiency.
Another engine that is often compared to the 4BT is the Ford Powerstroke 7.3. While the Powerstroke is a larger engine with more horsepower and torque, it is also less fuel-efficient than the 4BT. Ultimately, the choice between these engines will depend on your specific needs and preferences.
