You can go to KB's website. There is an article where they dyno'd a car on a chassis dyno and then pulled the engine and put it on an engine dyno. They did several tests. It was all 15% drive train loss +/-1%.

The 2013 GT500 is a legit 700 HP car.
No. It's a 662 hp car - as validated on engine dyno with SAE certification.

From SAE:
"To tout power and torque ratings as "SAE-certified," engine manufacturers must have an SAE qualified witness watch over the entire testing procedure to ensure that it is conducted in conformity to SAE standard J1349."
