70%

varies depending on type of dyno and its calibration setting.
Who cares about bhp honestly? unless its for bragging rights to people who are clueless about whp.

anywhere from 15-20 % i think, depending on the transmission. automatics have higher loss - hence they come with shorter final drive ratio to even the 0-60 times.
