This is true, but my thought concerning "area under the curve" was the actual total horsepower curve. Big peak numbers are fine, but greater power all the way up (i.e. fatter power curve), even at the expense of a big peak number, results in a much more streetable machine. I like big power down low, through the midband and at the high end. Damn, I want it all!

Well said. Some people just don't understand the power under the curve. As far as shifting to keep your self in the curve, I do like have my power come on well before 5000 rpm. The cam I have produces good gains over the entire curve on both hp and torque. It never falls back into the stock curves. Not even on the low end. MPH is a good way to measure hp. Mine varies from 114 -118 mph depending on weather. My best times have come from lower MPH runs.

I've noticed this trend over the past few years. The trend is to think it's faster to have a wide power band despite having much narrower gears. People talk like they are hammering their car from 1500rpm and wanting to outrun people. If that worked, we'd have only 6th gear and no others.

I understand. So it's wording. YOu said "under the curve" when you mean "throughout the power band". They're different. The curve is the gear range. After all, who is unable to downshift? If so, you better get your tranny fixed! LOL!

Having a flat hp curve will leave you with a small power band which may or may not be able to be held since rpms could easily drop below when shifting. Changing the final drive gears will not always cover the gaps and could leave you with car not worth driving on the street.
Having a nice arc to the curve leaves you power through out each gear and gives you a wide power band. This is real nice for street driving and any type of racing. This is how that trend is making cars faster with lower peak numbers.
All the gear shifting you like is just how you utilize the power thats there.
