Less power used to accelerate rotating mass means more is available to spin the dyno drum.

No you still will not.


Which part are you not understanding about:
HP measurements (engine OR chassis dynos) measure torque at discrete (STATIC) RPMs.
How does the rotating mass affect the torque measurement at static (non-accelerating) RPM?
Answer (again) it does not.


Torque is just the FORCE being applied to an object with a Mass.
How does the mass of the object affect the force being applied to it? It doesn't!


Again, dynos do NOT measure how fast you can change RPM.
They measure ONLY the torque applied while at a static RPM.
A dyno measurement is NOT a race from one RPM to another.
