The way we know this, is measuring the driveline shaft deflection. If a driveline of known strength deflects X amount, we know there is X amount of torque being applied to it. From there it's a simple mathematical equation to determine the HP.
Of course we don't measure shaft deflection to determine the HP. That is just a side effect of data-logging the clutch performance.
I used to laugh at the often quoted 8000 HP figure. For at least the last eight years, it has been far beyond that.
How were you measuring driveshaft twist position? Strain gauges?
