Your apples to apples test wouldn't do the lighter flywheel any justice. It would be good to test the extra drag on the bearings due to the extra 10lb but the real energy savings will be seen during acceleration. Also if the flywheel changes your engines stall speed it may cause you to drive in a different gear at a given speed. If the test is at that given speed you will get different resulted. So what I'm trying to say is that results of a single set of tests may vary from what you get in day to day driving.
All I was trying to say about the dyno results, is that it takes a given amount of energy to accelerate a given object, but how fast you want to do it determines how much power you need. If you reved up the engine slowly the power needed for the flywheel will be less despite the fact that the work done on the flywheel is the same. Keep the engine at a constant rpm and no work will be done on the engine. All I wanted to point out is that the 8hp gain isn't constant but conditional.
I too hope to see some real test results, but it doesn't hurt to look at it from all angles first, so that one can understand how the test results may or may not be applicable. To all situations or specific situations.
