Every diesel owner knows turbochargers, most commonly referred to as turbos, are required to increase the performance of your truck. Turbos are able to increase horsepower through a forced induction system by compressing the airflow into the engine. The compressed air forces more air into the cylinder, which in turn means more fuel can be added. The combination of which allows greater power from each explosion in the cylinders. The result is an increased power-to-weight ratio of the engine resulting in increased horsepower. The typical boost provided by a turbo is 6 to 8psi, which increases the air in the engine by 50 percent on average, resulting in 30 to 40 percent increase in power.
Turbos operate by using the exhaust flow of the engine to spin a turbine. The turbine spins the air pump at speeds greater than 150,000 rpms. To prevent failure of the turbo, most use fluid or ball bearings to spin the turbines. Liquid bearings support the shaft of the turbine on a thin layer of oil constantly pumped around the shaft, both cooling the shaft and allowing the shaft to spin without generating too much friction. Ball bearings use a smaller, lighter shaft and are made of advanced materials to handle the speeds and temperatures present in turbos. In the case of twin turbos, two different-sized turbos are used. The smaller turbo cycles very quickly, reducing lag caused by the larger turbo cycling.
In the current diesel industry, numerous companies manufacture and produce turbos. Knowing which turbo to purchase can be difficult, and in this roundup we offer a round of the most brands and companies.
