But IMO the two curves, with same scales, on a common graph, tell the story at both ends of their respective curves.
As in; from the power curve alone, it is difficult to see what is going on at low rpm, and from the torque curve alone, it ia sometimes difficult to predict what will happen when a certain change is contemplated.
Either curve can be created from a missing curve; with a simple calculator, it just takes a few minutes. If you really want to see the curves in action, convert the graphs to ftlbs or hp, to the road in each gear and graph that! And then....
