This is nothing new, but I'm confused also.
Doesn't the mustang dyno measure based upon how quickly it can accelerate the rollers? (I suppose that would be inertia based - duh).
How does a load based dyno work. Does it measure how much it can resist the wheels? If so, wouldn't a heavier wheel, brake rotor affect this also?
I have heard the same issues quoted with HKS's dyno. |
Mustang dynos measure the actual amount of torque applied to the rollers by measuring the resistance of the extreme large electric motor attached to them. Inertia-based dynos measue how fast the car turns a heavy drum.
