Nope.
HP is Horsepower, the preceeding letter is where its measured.
WHP @ at the wheels (rolling road dyno)
HHP @ at the hubs (chasis dyno - the one at Abbeys)
BHP @ at the flywheel (can ONLY be measured if the engine is removed from the car. otherwise its an estimate)
*edit. i think i quoted WHP earlier... thats me being lazy. sorry. Abbey dyno is HP at the Hubs, not the wheels.
Fair enough seem cars go against all industrial machine in the world which bhp is taken when the engine/motor is under load and HP is what the motor alone produces
After doing a little reading the bhp is just a Braked measurement which can be measured at any point so you can get a Braked horsespower output from the fly hubs or wheels,
But as you don't just sit on the engine and float down the road the entire car as a machine's bhp output would be at The hubs as it's that that makes the car move so the bhp at the hubs is the important number unless your looking for a penis extension down the pub
Guess it depends how you word it
My car outputs 300bhp
Or my engine outputs 300bhp
