Improving my W124's handling
Even though we make 700wtq at 4000rpm or so it still does not make any sense because at 450wtq at 6000rpm is still more to the wheels in the next lowest gear. Until you start getting into the upper gears. It about evens out at the top of 2nd to 3rd and then 4th it is almost even the other way around. Slight advantage to 4th gear over 3rd when tq drops below 500ft/lbs. Where in 2nd it has to drop below 445ft/lbs.

Making 7000lb/ft of torque at 1500 rpm is absolutely meaningless because you will never be able to use it. The factory rates this stuff this way as well. Even the V12 TT engines and what not are making full tq at 1800 rpm. But guess what you are never going to use it. Or if you do it is at launch for about 2 seconds. And guess what you cannot use it because it is to much. Look at your power curve and do the math per gear in your transmission and then to the wheels through the final drive.
