STI torque... rises to 3400, then dips down, corresponding with the lull in the HP, climbs again around 3850 through 4400, then noses over and keeps going down at a mild slope. The shape of the curve is terrible.
Evo X torque... climbs nicely until 3900, then goes over and slides down. Again, either it rises and falls quickly, or the Y-scale is very different from the others. A much better shape than the STi. It peaks to 235 around 3900, nice early peak, the STi at the same time is in a rut but still delivering much the same figure.
G37x torque... starts much higher than the others, has a lower slope on the rise, has a broad flat peak, finally starts to slow fall past 5000, but still a lesser fall off than the other two. It's incredible.
Analysis. Again, the Evo X presents a nicer and smoother delivery curve than the STi, yet despite that, the STi has more torque at all points along its curve, no matter how ragged and ugly it may be. But if it's a quest for a smooth torque curve, the G37x laughs at both of them. The STi holds small leads for most of the time, except for its lull points (I don't know why those are there). However, its torque is up and down all over the place, its rises and falls are steeper.
