Message Horsepower is derived from torque. If you have higher torque across more of the RPM band, you will have a faster car. It's all about the area under the torque chart.

You could have 100 ft pounds of torque until 10,000 RPMs where it might jump to 200 ft pounds. For most of your RPM band you're going to be below 200 HP; then at 10K, you're going to jump to 400 HP. But if you have to shift right after that, what good does 400 HP do for you? Sure the dyno says you have a 400 HP car, but for practical purposes its only 200 HP.

Key factors: area under the curve and the time spent there as a result of gearing.

Just my thoughts...
