: The whole "area under the curve" thing is what I was hinting at. Rev-range (not RPM) is equivelent to elapsed time, a greater area "under" the curve (in a 2 dimensional sense) is a an increase of the torque to time ratio.

True enough. My point was that without having some dyno plots on the old vs. new motor, we don't really know much more area under the curve we really have. My guess is that they've moved the whole power band higher, at the expense of the low end. This gives nice high HP numbers for marketing due to the mathematical relationship of HP and torque; VTEC, and indeed VANOS, are just tricks to get SOME low end from a high-revving motor. It doesn't, however, result in a significantly better performing car in the real world, since all you've done is pushed the torque up high.

The direct evidence of this was that I was running with the S2000 at Laguna Seca last week in my Coupe. 240hp vs. 240hp, and he has a huge weight advantage. But he had a hard time getting out of the corners, since all his torque is up high.
