Our experience has shown as much of as a 19% drivetrain loss for manuals and 23-25% loss for automatics. Which is consistent considering the 15-17% drivetrain loss that is generally accepted for DynoJets. Personall I believe that is still a little high, and would like the general acceptance to be 10-12% loss for DynoJets, and 15-18% loss for Mustand Dyno's.
Another way to measure horsepower is by metered air. "X" amount of measured air, can only make so much horsepower. Typically I see 42-43lbs/min of air, making about 400-410rwhp on my Mustang Dyno.

It is the opposite; all dynos measure torque and calculate horsepower. Actually there is no way to actually measure horsepower, it is always calculated.
But like most have been saying, a dyno is to measure the benefits of different modifications to your car. In the long run, it is who gets to the finish line first.

DynoJets measure acceleration of a rotating mass over a given time. Horsepower is work over time. Torque is then calculated by the intergral of this measurement.
Mustang dynos measure torque via a load sensor, and then derive horsepower from that measurement.
