Tyler I seriously doubt Im running 650 at the crank---- I think there is less drive train loss with the DCT so its higher than the 560 factory number but not at 650.
Definitely over 600hp for sure.

It doesn't matter how advance they made the DCT to be. It is inevitable to avoid the general rules of physic. There will always be drivetrain loss unless the dyno is directly connected to engine.

General rules are 15% for FWD, 18% for RWD, 20% for AWD.

Even at the lowest 15% drivetrain lose, your car still dyno at 631HP.
At 18% your car is running 654HP.
