One of these days, I'm going to have to get my water brake engine dyno back into operation. I can simulate a really long uphill run for ring seating with that little toy! I'm tinkering with the idea of making it portable, on a 16 foot trailer with a 500 gallon plastic tank for the load cell water, and an 18 wheeler radiator to keep the water cooled down. It might be fun to tow that rig to a car show or a swap meet as a "Lie Detector"!
