Dyno reading close to the stated factory power

AutoChip tested a 2008 diesel Honda Civic on its dynamometer. The car was in its factory configuration during the measurement; the video says the DPF system and other components were still in place.

The video gives a factory power figure of 140 hp. The dyno recorded 142 hp. The torque reading was also close to the factory figure cited: nearly 339 compared with 340. The video does not specify the torque unit.

This measurement shows how a dyno can compare the actual result for a particular car with its stated factory figure. The stand is described as synchronised and braked; a single example does not independently establish accuracy for every vehicle or test condition.
