Crank readings have been what manufactures used to get the performance numbers forever - if the dyno reading is also crank then I see no problems with it, its a more accurate way to measure the engine performance than anything else as it doesn't suffer from momentum nearly as much. Again physics. Sure from crank to wheel you will see losses through the chassis like every car, but isnt that loss essentially a constant not a variable?

But it isn't a dyno reading it is.... Oh never mind. I give up already.
