I'm pretty certain the drivetrain loss on WRXs is nearly exactly 40%.
There's been tons of research done on this Downunder
A FWD also has less drivetrain loss than RWD, because the wheels are closer to the engine.
Several tuning places have dynoed WRX between 160-170 WHP.
That's 160/227 ~ 170/227 which translate to 70%~75% Wheel power.
