Since 1958, Go Power History

In 1958, Go Power Systems began providing engine testers worldwide with dynamometers and engine-testing equipment. Fifty years later, Froude continues to supply the affordable Go Power engine-testing solutions to a wide variety of industries.  Go Power products are sought after for their durability, dependability, and repeatability.

In 2002, Froude, Inc. incorporated Go Power Systems and added a wide range of portable dynamometers to the existing product line.  Froude has been involved in testing ever since William Froude invented the hydraulic dynamometer in 1877.
