At what point of the HP\Torque curve do you shoot for when picking gears?

Happy,
It really depends on your motor...It truely has a "sweet spot" where it perform at it's best...The tough part, unless you have access to a dyno, is finding it,,once you know it's rpm "sweet spot" then gear to shoot for it...
The other guys probably have an easier answer for ya.

We put a chip in to limit rpm to the engines component quality then pick gears to peak the rpm at just under the chip number. Usually the rpm range is centered at about the max hp curve, depending on track size.

I try to keep the motor above peak torque at all times. Running a high compression motor below that tends to be hard on parts and you can usually get away with more compression without having to worry about detonation. It also tends to be easier to drive when the track is slick. This is assuming the motor has a large area under the curve so your hp isn't dropping off too fast.
