Every driver wants their car’s engine to be as powerful as it can. To measure the amount of power in the engine, mechanics perform a dyno test. The device used for the dyno tests to measure the force, torque or power in your vehicle is known as dynamometer.
When the results of the dyno test are unsatisfactory, mechanics dyno tune the car whereby they make modifications to your vehicle’s key components, such as the ignition, fuel level, and air supply so that your car performs smoothly and achieves highest horsepower levels and displaying some serious torque all
Below, we take a look at what what a dyno test is, how long dyno tests, how much does a dyno test cost and every other thing you need to know about a dyno car test.
How Is Dyno Testing Done?
Before starting the dyno test, it is important to make sure that the dyno test machine is not out of calibration because wear and tear and corrosion impacts dynamometer’s calibration. If that is the case, a calibration arm is installed in the dynamometer to recalibrate the device.
There are two main kinds of dynamometers: power absorption dynamometer and power transmission dynamometer. Power absorption dynamometer measures an engine’s torque or power in a process in which the energy given by the engine is absorbed by the dyno test motor. In a power transmission dynamometer, on the other hand, the power is transferred to the load connected to the engine
To perform the dyno test, mechanic places the drive wheels on a loaded drum. Followed by this, the mechanic depresses the accelerator to rotate the drive wheels (and drums) for measurement. Most dynamometer tests are actually quite short, lasting no more than two minutes. Of course, set-up time must be factored in. All in all, an experienced mechanic can complete the dyno test in 30 minutes or less. It is important that only a qualified mechanic performs the dyno test on your car, as there is a risk of the car falling off the dyno test stand and dyno test can go wrong.
When Does a Car Need a Dyno Test?
Dyno car test significantly increases the horsepower and improves the engine’s performance. Other advantages of engine dyno testing include:
- Increase torque which improves acceleration
- Vehicle performs smoothly
- Improves the vehicle’s fuel economy
Now that you know what is a dyno test and the benefits dyno test offers, the question arises that when does a car need a dyno test. The owner’s manual includes details about car maintenance but it is recommended to dyno tune a car after two years or 48000 kilometers (whichever comes first) to ensure that all components of your car function smoothly. All faults in spark plugs, ignition or starting the engine are addressed in the dyno test.
