yeah its pretty damn high, but what im explaining to others (i used 50kw as an example) that no matter how much power you have, the drivetrain will always take 85kw (for an M35 auto) not 30% which may end up being a bigger figure. i have more experience with silvias, AUDM S15s have around 40kw drivetrain loss, a little more efficient than their S13 bretheren at almost 50kw. but thats technology advancing. better still my honda lost 30kw which i think was pretty good!
