1wild, are you really a 16 year old or do you just play one on the net?

I gave you my example. The hot rod's torque curve really lit up around 3000 rpm and peaked at 4900 AT WIDE OPEN THROTTLE.
I got my best mileage cruising between 2300 and 2400 AT PART THROTTLE.

What you seem to forget is that the higher speeds induce higher drag. Stick your hand out the window at 30 mph and try it again at 80 mph. I bet you'll feel a difference. The car feels the difference too.

Now either play nice or go away.
