Electric vs. nitro, watts/horsepower.

The dyno used by XRC is a nitrodynesystems it uses a real drag to determine real power, instead of a big wheel and reving to create theoretical numbers.

But on that note, HP is just a theoritical number based on rpm and torque based on computer formulas

Nothing theoretical about it (except some manufacturer's claims).
1hp=33000ft.lbs/min

The ability to do work over time.

Sorry, i wasn't clear on what i said. On 1 to 1 dyno's, the rpm and torque are the only things actualy measured, Hosepower is calcutated in the computer. The theoretical part comes in with how the car is setup, you can have a camaro that makes 300 hp on a dyno but with the proper setup can show more power at the track than it showed in the dyno room.

Such as airflow.

The dyno registers how long it takes to produce the rpm with a certain resistance.
