Diesel vs gas......................
OK folks, there have been a few to many diesel vs gas threads that have shall we say gone to "Hell and a hand basket"! So if all of you would put in you BEST, no flaming reasons for going gas vs diese...

LOL, and no, I did not read all 360 pages, but let me state some basic physical property facts.
Power (watts) = Torque (N-m) x Angular Velocity (rad/sec)
Power, or HP, is the rate of energy consumption, or delivery, and cannot be measured directly.
Torque is a rotational force that can be measured directly.
Angular Velocity (tire speed) can be measured directly.
So HP is a derived or calculated value.
It is interesting to note that in the equation above, that HP cannot be a constant unless the torque slope and velocity slope are inverses of each other.
This means an increase in HP at a given RPM automatically means an increase in torque at that same RPM, so these two values are not mutually exclusive.
So to argue about which is better, or worse, really requires Torque vs. Velocity, and HP vs. Velocity, graphs so a visual of where these values peak and how they change can be observed.
Gas vs. Diesel is moot without this data applied to tow/drag/fuel economy/etc... applications.
Have fun, :)
