bhp is measured with the engine out of the car on an engine dyno

the only way a chassis dyno is going to calculate bhp is if the tech doing the run knows the manufacturer supplied bhp number before running the test, and then subtracts the measured rwhp from the manufacturer supplied bhp. this would only work if the car is bone stock, and is still ultimately a guess.
