Interesting analysis, but since these are different dynos, different days, different cars, different elevations, different corrections, etc., one can't directly compare the two specific results, though we can look at trends between the two curves. That said, average or total hp under a curve is good, however, even that isn't fool proof. If two cars have the same average or total hp under the curve from 3500 to 6500 rpm, but one has more hp at the top end (say, 4500 and up as in this case), and the other has more hp at the lower end, the car with more hp at the top end will be quicker, because racing mostly happens from around 4800 or 5000 through 6500 rpm, esp. in modern automatics. The gears are spaced closely together and thus, during a race, will never drop down to the lower rpm range where the other engine makes more torque.
