You obviously skim read those articles and didn't take the time to understand what they were saying (parts of them were also completely false). Download each image below and look at them together:

http://yfrog.com/0kabpowerp
http://yfrog.com/0fabtorquep
http://yfrog.com/0fathrustp
http://yfrog.com/10bthrustp

The first is the torque curve for Engines A & B. The second is the power curve for Engine A & B. The third is the thrust curves for Engine A. The fourth, the thrust curves for Engine B.

Points to note:

1) In any given gear, acceleration tracks the torque curve.

2) At any given speed, acceleration is maximised by choosing the gear that gives the greatest rear wheel thrust. This will be the gear that puts you at the rpm of highest power.

3) Since, in a non-geared kart, we only have one gear, acceleration tracks, exactly, the torque curve (see point 1 above).

4) If torque were constant throughout the rev range, acceleration would be constant throughout the rev range but power would be ever increasing.

Anybody who denies the above four facts hasn't taken the time to understand Force, Work Done, Power, Speed and Acceleration.
