I was under the assumption that it measures WBHP, then lets the engine run down to zero, which would measure the drag and therefore the drivetrain loss. Then add the WBHP to the drivetrain loss to get the FWBHP. Therefore accurately measuring the FWBHP.
Then I was hoping to be presented with a pretty graph showing both accurate WBHP and FWBHP, from which I could check that there was not an abnormal drivetrain loss. That was kind of the whole point of the RR day. But we are now saying that the conversion from WBHP to FWBHP is just purely a % being added on? Kind of defeats the point doesn't it? I might as well just say... "its actually 650FWBhp"
