The FQ400 is such a track capable car NOT because of hp/l (come on, are you serious?) But because of REAL WORLD things like WEIGHT, suspension, tires, gearing etc.
This is the last time Ill go over this in this thread. Lets make a kit car, you have two engine choices. Engine 1, 400hp 4L, 600lbs, or engine 2, 400hp 7L, 300lbs. Both engines are the same physical size. Now tell me, which would you rather have in you kit car? Can you see how hp/l is meaningless now?
As far as your "tractor" statement goes, TORQUE moves the car, the torque curve (or power under the curve) is what you feel.
Take a look at this graph:
Between 3600 and 4800RPMs that car will be accelerating the hardest, NOT by its peak hp. At 2400RPM (even though its making 150hp) it will be pulling just as hard as at 5000RPMs (although its making 300hp there).
