No, area under the torque curve is what you want to look at because:

 

Can't wait for this thing to be released. I think we're getting bored.

 

RedMx5, thanks for the additional info. A few of my previous arguments are flawed...

From what I now understand, torque curves show what the forces the engine can produce over the engine's operating range. The horsepower curves show how that torque is effectively put to the wheels due to gearing.

I still have a hard time believing that an engine with a constant 200 lb-ft of torque from idle to redline will push you into your seat with the same force at all engine speeds. Maybe I'm stubborn

 

I love this stuff. I compiled all that data just to have more to look at. I check this thread like ten times a day just to see if there are any new developments

 

Very close, but no cigar. The horsepower curve shows how torque is integrated over time (RPM). Basically, torque shows how much power the engine makes at a given RPM. It's directly related to the volumetric efficiency of the engine as a whole (from intake filter to exhaust pipe outlet). However, at high RPM, that torque is being applied more often, as the number of power strokes per unit time has increased. As such, even a low torque engine (like the F2xC we know and love) can be peppy and powerful at high RPM.

 

For you torque lovers.

C.A.R.B certified = Priceless

There's some things you can't buy, and some cops you can't bribe ... For everything else there's Comptech

 

Good stuff

In central Virginia, a C.A.R.B. means nothing more than what you look out for on the Atkins diet.

 

hahahaha, good stuff, i'll be lookin at the longterm of the first 10 people that buy and install this to see how it holds up over the year of a average joe beating. i personally love this solution, power everywhere, damn nice peak numbers, and sick pre vtec power. as long as its longevity doesnt prove poor, i will be thinking about this product in the future.

 

Slim, you're not being stubborn, you're just trying to make theory match your experiences. You are correct about an engine with a dead flat torque curve not producing linear acceleration, so it's more than fair to ask what the heck is going on. It's actually a very good question, and one I can answer.

The rule that A=F/M is idealized, in that it only considers three factors. In the real world, things are often a bit more complex. LOL, we don't live in a vacuum. The reason constant torque doesn't produce constant acceleration in the real world is because the *effective* mass (or "load") increases with increasing velocity. Air resistance and friction both eat up more of the force available to produce acceleration as speeds increase.
