My vote is 9-10 hp/lb. My 930 is in the 4-5 range and it's a lot of power to handle unless it's dry with warm tires and even then it's going to break the tires loose at lower speeds with anything over half throttle. With that said, new cars with all the electronic gizmos make really high hp cars managable by almost anyone, but it takes away the fun when you feel the car backing the power off.
