I do as well. 1000 hp Supra power curves do not impress me for this reason.

I consider the "practical" max power under the curve to be the maximum rpm shift point and the rpm the motor drops to after the shift. The maximum rpm shift point can be determined by the safe limit of the motor, it could be the valves, it could be a sharp drop off in horsepower or other limiting factors.
That is making use of the horsepower available. Setting the limit at 5250 rpm makes no sense to me at all. If that was the case we would still be running TPI motors.

So yes, power under the curve is the term commonly used to discuss torque numbers before HP numbers come into play. Although I like the other definition I've seen a little better: that being just simply torque. Which after 5252 is "under" HP "curve". Don't get mad just for clarifying. Heck, look at this one post. It's discussing 2 things not even related to the discussion! Average HP per gear, and rev limiter, which have nothing to do with power under the curve.

Here's an example of a better example. I like this better than the one I've seen the cam guys use anyway. It's not exactly what I want, but it's late and I'm too tired. So anyway, the red one has more area under the curve than the blue one. I like that way better. Although there's too many interpretations I guess. So nevermind. But the original poster might want to define what he means since apparently there are so many ways to view it.

I guess ill be the one who steps out of the box, but I like a violent top end. As long as I have enough power to drive at 65mph @1500rpm in 6th gear im happy. If I need more TQ, (or tq multiplication for that matter) ill down shift.
