I see there are still no takers to answer you...maybe because its "borderline" technical forum...
...maybe nobody cares...

Anyways, all engines produce TORQUE! Horsepower is a product of torque and rpm.
If two engines produce the same torque, the one that does it at a higher rpm will have more HP.

"Power to the wheels" is really what a "dyno" is measuring, so they are theoretically the same thing.

If you really meant flywheel vs. dyno, then the "flywheel" is what comes out the engine and "dyno" is what gets to the wheels, which is allways less than flywheel Hp, because of the friction in the tranny, the differentials and all the other drivetrain components.

Manufacturers allways publish the flywheel HP, because its a bigger number.
