If you look around you'll see that they dyno around 300awhp in stock form wich translate to around 380 crank hp with a ~20% drivetrain loss! The Audi line-up of F/I engines seems to be underrated by the company, like the S6 which is advertised at 420hp but has around 480 and the S8 thats advertised at 520hp but dynoed 480awhp in this Motortrend video!
