SAE updates dyno testing standard

The Society of Automotive Engineers maintains auto testing standards, among them a dynamometer testing standard known as "J1349". It's recently been updated to include provisions that prevent altering horsepower figures with creative uses of exhaust systems, fuels, and oils.

Quote:
David Lancaster, chairman of the committee that developed the test rules, explained that new technologies open new loopholes in test procedures, which must be periodically plugged. Before 1971, for example, a manufacturer might connect the engine's exhaust system to a vacuum pump, gaining power by eliminating back pressure, the resistance to free flow caused by mufflers. Under the 2006 standard, a complete production exhaust system, or one of equal back pressure, must be used.
