Either install it and put a few road miles on it - - - -

Give me time to scavenge up the bits and pieces of my dyno that's been in storage for 15 years and make a road trip. All it really needs is a good source of water to fill the brake chamber. I used to run a 1 1/2" diameter line on Nashville city water pressure, but I was pushing enough volume through the load cell to handle a 700HP at 6500 RPM engine without boiling the water inside the unit. Lower HP engines can be tested with a lot less volume of water.
