Yup it's derived. If it wasn't it would be in the 5xx which is bull.
Places that know what they are doing always do derived.
I hate it when people are like 5xx! Torque and it's not derived. Fail!
I disagree. This is the first dyno i have seen on this Forum that has derived. Most of the time you see KW at the wheels and torque calculated at the engine. Actually, its basically standard. And that dyno would not have been in the 5xx at the fly wheel. No way.
