Discover The Precision and Performance Only A Hydraulic Dyno Can Provide

Our Start

Xact Dyno was formed in 2003 with the purchase of Arizona's first hydraulic dyno from Dyna Pack in New Zealand. This type of dyno opens up a whole new realm of testing possibilities, letting us tune like the OEMs tune since an engine dyno is also a hydraulic dyno.

Our Vision

We strive to focus on one-thing: performance testing. We do this because it is our belief that focusing on one thing allows you to do it exceptionally well. We don't do installs, however, we'll be glad to handle small parts installs like injectors, WideBand O2 sensors, and other testing items as they are part of the testing process.
