Sounds like a simple, straightforward dyno system that should give at least 
very repeatable, if not accurate, results. The accuracy would depend 
primarily on knowing the exact moment of inertia of the flywheel, which you 
should be able to calculate to within a few percent. I guess they could use 
the electric motor to load the system and measure the electric power output 
that balances the engine's input, but that would involve more calibration 
factors. Should be pretty repeatable though. I'll bet the size and weight 
of flywheel needed to handle 1000 HP is pretty huge. Let's see now, if we 
make it out of boron fiber composite and use depleted uranium for the 
weight, we could reduce it's size and mass a lot. And I guess they will be 
needing a new use for depleted uranium, now that the military has decided 
that it and lead are an environmental hazard. Is there a category for 
inertial powered land speed record cars? I know they have one for battery 
powered cars. Maybe we could work on the fastest inertial powered Sunbeam. 
What would it take to break 200 mph?
