Overall, the DTS units are more compact than what we're used to, and yet they offer many features available nowhere else. The ease of engine installation makes it possible for a single technician to prepare an engine for testing, and that saves time and effort too. We look forward to using these dynos in our Challenge testing, and we appreciate the innovations coming from DTS. You should see the new DTS 1600 valve spring dyno! This cool tool tests the springs to your preset limits from installed height to max lift, and offers repeatable testing for these critical components. Compared to the "manual" spring testers we're used to, these are light years ahead.
