Mine came in at 377hp stock at the wheels. So at 450 hp crank, this would be a 16% loss. IMHO I do not think this is accurate. There should be more drivetrain loss. Guessing is all we can do as far as what the drivetrain loss really is.
A different Dyno? Maybe.
But do we really know if Audi "underrated" the power a bit. Could be.
Plus, using 25% means that Pat is closer to 700 ft/lbs.
"I think these cars are closer to +25% driveline loss"
Nevertheless, the Eurcharged tune Pat has is incredible.
