that a horsepower is a precise unit of work but yet there exists variations in measured power dependent on what piece of equipment you use. I understand probably as most others do that dependent on the mass of the drum used in an intertial dynamometer, it will result in a different load placed on the powerplant. However, the only difference it should create would be, in our case, a variation in the measured power/torque within the spoolup range of engine RPM. Once the turbos have achieved target boost pressure there should be absolutely no difference in the power/torque measurement irregardless of what dynamometer is being used.... and it just so happens that both peak horsepower and torque are produced AFTER the maximum target boost pressure is achieved.......... go figure that crap.
