WHP - BHP for M6

does anyone know what the actual transmission losses are on an M6?

most common answer seems to be 15% or 18% ?

No way to know the "Actual" losses as BMW seems to underestimate crank HP on stock motors, and there are tons of completely random dyno runs posted on the internet... Best guess is the DCT is 12-15% loss.

There was a YouTube video with a Ferrari that calculated the drivetrain losses to more like 11-15%. I do not recall the video name but saw it a few years back when I was looking to perform upgrades. I would assume 11%.
