Rotor Weight Effects on Dyno Results

[Berkeley and Bill Conner]

Do any of you have experience with installation of the NX 2000 brakes
lowering wheel horsepower measured on a dyno?  The big rotors add about
5 pounds of rotating mass to each side which should reduce the measured
horsepower at the wheels.  But by how much?

A good mathemetician could probably calculate the expected change, but
it's way over my head.

Thanks for any input.
