You've got this backwards. You don't take Ford's stated engine output and divide by your whp. All that shows you is the difference between Ford's stated number and what you're seeing to the wheels.

There is no way in flying pig shit heaven this car is only experiencing 7.5% parasitic loss through the drivetrain. If these cars are truly dynoing in the mid 140's stock, all that shows is Ford is underrating them from the factory.
What's that?? You'd like an eco-tune...
