Hmmm...totally unscientific scaled example: ISTR hearing about a classic VW Bug engine ouput: 96kW With a vehicle of known mass, measuring time from 0 to some arbitrary speed should give a ballpark value of the power output of it's engine (at least the part that ends up pushing the car once friction and thermodynamics have claimed their share). Also, in the episode about the internal combustion engine on The Secret Life of Machines (totally awesome Brittish(sp?) show) a demonstration was given where a guy sat in a swivel chair and held out a 2x4 (6 feet?) with the tiniest model airplane engine they could find (a *really* small thing, had it's own built-in micro fuel tank) attached to it with a common-sized model airplane propeller. This was more than enough power to rotate him at a decent clip.
