"Since Go Power Systems introduced its first dynamometers in 1958, we have continuously developed our products to meet the ever-changing needs of our customers. Our products have continually been proven through solid engineering design, superior material selection for reliable performance, and unmatched durability for years of service in any engine testing environment. Go Power dynamometers, data acquisition systems, test cell equipment and dynamometer/engine stands are supplied worldwide to engine manufacturers and developers, engine tuners, remanufacturers, rebuilders, overhaul facilities, and garage workshops. We have provided many solutions to technical colleges and training centers as well as to professional and amateur race teams to improve their performance where it matters. Go Power dynamometers are all about rugged portability. Maybe you don't have a test cell. You might be limited on space. Go Power dynamometers can be used just about anywhere, (even on a shipping skid) thanks to their small footprint. We like to say : JUST ADD WATER. It's that simple. We are also proud to say that Go Power products are made in the USA, in Novi, Michigan, near Detroit. An advantage to owning a Go Power portable dynamometer is that when your engine testing is completed, the dynamometer can easily be disconnected and stored until it is required again for service. Truly the ultimate bolt-and-go solution for all of your testing needs. The Go Power D100 small engine dyno tests engines from 2 to 100 horsepower at speeds up to 14,000 rpm with durability and accuracy to meet the most demanding industrial requirements. This lightweight, compact unit is rugged — constructed of high-strength aluminum alloy and can be operated from a water supply almost anywhere. Its extreme versatility makes it ideal for use with “go-cart” or outboard marine engines as well as industrial durability testing for engines and components.
