Dyno Testing your ride- Is it necessary?

When ‘dyno testing’ is mentioned, people straight away think of showing off one’s the torque or power of one’s car.

Actually that is only one purpose of dyno testing. A computerized engine dynamometer accurately measures torque and rpm and then can accurately calculate horsepower.

Knowing your horsepower and torque gives you a solid basis for making changes in the engine’s tuning or to the engine itself. How? Easy. If horsepower and torque go up the change was likely correct, if they go down you’ll need to make some changes.

The dynamometer applies various loads on the engine and measures the engine’s ability to move the load. The dynamometer may be connected to a computer which calculates the output of the engine. The engine is run from idle to its maximum rpm and the output is measured and plotted on a graph.

Dynometers are used to measure the factors such as : crankshaft torque, intake air and fuel consumption rates, air-fuel ratio for the intake mixture,environment pollutant concentrations in the exhaust gas and temperatures and gas pressures at several locations on the engine body such as engine oil temperature, spark plug temperature, exhaust gas temperature, intake manifold pressure.

To date dyno testing is the most accurate way to determine if the fuel saving device or the bolt on turbocharger your bought for your ride is effective.

Dyno testing will not come cheap, however, it is the price anyone who wants a 100% iron clad guarantee that the performance of his engine did improve upon fitting external devices.
