Our History

Award winning manufacturer of dynamometer products and related equipment since 1976.

In 1976, John Petelinsek set out to improve upon the traditional water brake dynamometer. The result was an affordable and durable dynamometer with increased absorption characteristics through a simpler, deeper pocket design. Power Test, Inc. was founded, and John spent the next 25 years focused on building his company and providing the diesel engine market with a durable and reliable product with the best customer service in the dyno manufacturing industry. In 2003, Alan Petelinsek purchased the business from his father and continued to build upon Power Test’s earlier success.

Throughout the years, Power Test has grown its product line through the design, manufacture, and development of a variety of engine and chassis dynamometers, engine and vehicle controls, and the latest technology in data acquisition systems.

In addition to growing its product line, Power Test has grown through acquisitions. Power Test has made two acquisitions in the performance engine testing market (Stuska Dynamometers in 2002 and SuperFlow in 2017) and purchased the transmission and hydraulic testing equipment division of AIDCO International in 2006.

In 2008, Power Test moved from Menomonee Falls to the current location in Sussex, WI. In 2012 and 2018, the building was expanded to accommodate the increase in employees as the business continued to grow.

A strong commitment to the growth of the business and technical excellence has enabled Power Test to be a globally prominent, one-source provider for testing power train components and vehicles.
