Okay,
The only area under the curve to be considered is the area used during
the race.  When you shift from 1st to 2nd the engine rpm doesn't drop to
idle.  The rpm range for a particular gear set may be from 4000 to 7000
rpm, so you want to set up the engine for maximum torque in that rpm
range.  Change the gears, change the rpm range for maximum "average"
torque.
