BHP Fly and or RW

[007 VXR]

Mine just made 671.6 fly and 533.6 RW


What did yours make on a dyno ?

No one on PH uses a dyno?

Unless you actually took the engine out and measured the flywheel power from the flywheel, surely the ratio of those two numbers is simply whatever number is programmed into the machine? Or do they do some clever coasting stuff to work out the gearbox drag?

This is why most use the RWHP numbers
Fly wheel are just pub talk numbers at best.
