PA Dyno inc. is a full service chassis Dynomometer testing and tuning facility. With our Dynojet 224XLC eddy – current brake dyno we can do steady state testing and tuning up to 2000HP and 200MPH.

Owner and Tuner Jeff Yost studied Motorsports Technology and attended EFI University’s EFI building and tuning class. Jeff has since passed along his knowledge to his son Shane to continue expanding the business.

With a starter attached to the Dyno we can start 410 Sprints and give those cars like dirt late models or modifieds with ‘speedway type’ transmissions a rolling start.

We can test ATV, Microsprints, UTV, Sprint Cars, Late Models, Diesel Trucks. We can test just about anything that is 2 wheel drive.
