Sorry, I can't take anything you say seriously anymore.
You can compare a hub dyno to a hub dyno, but nothing else. They are great for tuning and development because they rule out tire distortion as slip. As an example a Porsche i tune makes 526 at the hubs and 537 at the flywheel. Wheel power is at 443bhp on the Dyno.
Here, I am saying that a true 300bhp on a properly strapped Dyno Dynamics type Dyno is rare. I am saying this because i have dyno'd a lot - that are claiming over this - that do not make it. Surely you can understand that this is evidence to support it?
The car i have here now is making 247bhp, but it is only holding 0.6 bar at 6k so it is not a great example. I will slacken the straps shortly and see what the difference is.
