Even the amount of gas in each car throws of your results. Too many unknown variables.

How 'bout ECU differences. The '04 ECUs are unique I think, then they changed them. The '04s started out with ~250HP before they detuned them, so the potential for motor+ECU matchup to produce high power due to manufacturing tolereance was possible. The later ECUs they likely designed any chance of improved power out of them.

Or..if you don't like that idea...I like the idea of smooth housing reducing internal friction after being honed to a nice finish by a well used '04 rotor.

Why cant it be that the 04s are really faster??, make us owners happier; i mean you guys have the better key we have the better faster engine etc, etc.
