I'll give you two bottles of whiskey for it if you want to double your money! That dyno is probably better than half of the ones they use today, which are just accelerometers which can't give you a steady rpm hp reading. What a great tool for trying all the "what ifs". Also much better for testing longevity of the motor, which is ultra important in Salt flat conditions, i.e. 3 miles or more flat out. Who cares if the reading can't be accurately compared to the other dynos; we only need to know when we improve our motors. And you can use the wastewater to heat your house!
