There's a general auto section?
There we go. Though the info is still useful when comparing engines, no matter what the type. i.e., a higher horsepower engine is always better than a lower horsepower engine (unless you make up something stupid about one of the engines, like it gets 2mpg, weighs 7 tons, etc.).

You started this thread with
I know I'm gonna get some flames for this

Huh, should have just left the post as-is rather than respond to all the arguments.
Now I have to argue about arguing.
How about, "LS1's are better b/c they have more power, not b/c they have more torque" or "if you swap in a 200HP V6 b/c it has more torque, you'll be sorely disappointed" or "When choosing your V8, pick the one with the most horsepower."
Meh, I'm going to go run errands. The initial post is there for those who want to see it, along with commentary from those who disagree.
Now I have to argue about arguing.

First let me say that I think the LS1 is great. It delivers lots of power. I am not here to bash LS1's or V8's.

I bet you're happy with the outcome of today's game. At least now we don't have to listen to Auburn bitching about the national championship game.

Enter "torque".
In case anybody wants an independant source to learn about it for themself, rather than going on what I or someone else said. I checked a couple of the search results and they both seemed relevant enough. So rather than linking to just one page, I'm linking to the search.

If rpm is different you better not be quoting torque, because the same torque will give two different horsepowers.
I even included the sentance that could be misinterpreted, in case you want to use that. It's the 1st sentance.

The correct answer is that you can't accurately predict the outcome of a race simply by comparing two peak power numbers, two power to weight ratios, or two power to displacement ratios.
The rate of acceleration of a vehicle is determined by its torque curve, gearing, and weight, as well as rolling and aerodynamic resistance and the coefficient of friction at the contact patch.
F = m * a, where F is the net force with all factors considered, as mentioned above.
Obviously not.

So, how many times were you planning to start the same thread over again?

Here are some interesting links:

Anyways be the bigger man and just stop posting in this thread, you won't change their minds about anything.

Rpms include time.
Every ******* time.

Someone's still sore from their spanking.

Jim I know exactly what your saying, you CAN figure out everything by looking at how much torque you have, AND the rpms the torque carries to. But that would have to be said as " I have 300ft-lbs at 9000rpms" instead of saying " I have 514 horsepower at 9000rpms" But you cant go around rating engines by torque alone, you HAVE to know how many rpms is running to see its true potential.

acceleration= ΔV/Δt=ΔS/(Δt)^2
F=ma > kg*m/s^2 or lbf*ft/s^2
