Torque only wins races when it carries to high RPM. Oh wait, that's HP! Think about it. If torque won races, stock diesel pickup trucks would be outrunning all of us.

My basic understanding of the torque/horsepower relationship is that torque is the force that accelerates and horsepower is the force that maintains the speed

That is not the correct definition, basic or not. Torque is the measure of force on the crank, but if there is no movement, there is no work accomplished. HP is the measure of work. If there is movement, there is work, if there is work, you have hp. The more hp, the better.

True, but they are scored across a RPM range (which IIRC, ends at 6800RPM), so that negates the use of a short-stroke screamer...

I am sure several know this but:

Horsepower is nothing more than a mathematical representation or torque vs. RPM. Horsepower is the measure of work a horse can do. 1 Horsepower = 33,000 foot lbs per minute of work. The formula is (Torque * RPM) / 5252.

Depending on weight and gearing, yes a diesel truck can smoke your A$$ at the track. You give me the right gearing, a 1500rwtq diesel engine, and 2800 lbs with driver and I'll show you. I'll cross the 1/4 in 10 seconds at a blazing 2900 RPM,

I don’t think a 346, with the same weight, same gears, etc, making 502rwhp and 392rwtq is going to keep up with me – it will make a lot of noise because to make that kind of HP with that low of torque, he has to be twisting that motor to 7 grand.

Think about this. My buddy’s ’04 Stang makes 550rwhp and 590 rwtq – yet I manage to stay right beside him on the highway. Why? Looking at his curve, you see torque building as a function of RPM/Boost, whereas my torque curve is flat’ish across the band. My more efficient 461 torque curve is keeping me there – against his massive “peek” torque of 590. And I smile all the way to the bank!

Isn't that what most of us should be concerned about anyways.... Area under the curve, not peak numbers.

The two aren't mutually exclusive. And with proper gearing, peak hp IS the name of the game, but most of the bandwagon jumpers don't get the concept of SHIFTING. Depends if you're willing to lose races, or lose drivability.

Sounds good to me, I stand corrected
