What is dyno testing?

Dyno testing is done to measure the force and torque or power of any vehicle. A dynamometer, or dyno, is the tool used for these measurements.

Dynos can also assess the necessary torque and power to run a driven machine like a pump. A dynamometer designed to be driven is known as an absorption or passive dynamometer. In contrast, a dyno that can either drive or absorb is referred to as a universal or active dynamometer.

Dynamometers come in various forms to cater for slightly different applications. One example is a spring dynamometer, which is useful to measure a simple pulling force. However, it’s not great for measuring the force of an engine or the power of a machine. A standard dyno test characteristically uses electromagnetism to measure the force or horsepower of a vehicle.

Conducting a dyno test

First, you need to determine the best dynamometer for your purpose and install it properly to do horsepower testing.

The next step is to warm your vehicle’s engine to operating temperature while occasionally applying light loads to the engine. Then, steadily apply a full load on the engine while using the brake’s control valve to regulate the revolutions per minute (RPM).

When you reach wide-open throttle, continue to move between desired test RPM points with the brake’s load valve and record your findings.

Finally, reduce the throttle while unloading the brake simultaneously to ensure the engine returns to an idle.

Dyno testing enables car owners to discover ways to improve their engines’ power and torque.

While this may sound overwhelming, an experienced mechanic, like those on the Vortex Transmissions team, can perform a dyno test efficiently with ease. In addition, working with an expert mechanic gives you the benefit of tailored advice after the dyno test. For example, the mechanic can advise you on the best ways to improve your vehicle for maximum horsepower.
