Of course you are, if you need 100% of the available torque and must stay in 10th gear, that's what transmissions are for..... You don't have to stay in 10th... the 3.73s can always run one gear lower..... Until you're down to first gear THEN they have the advantage.....

That's been true since the days of the 3 speed transmission, doesn't change the advantage you get from lower axle gears.

More RPM= more fuel used is only true if the throttle input is the same for both, which it often isn't, what is more important is where the engine makes it's peak torque.

Oh I see, if real world numbers don't fit your narrative, it's obviously false numbers. Go find dyno charts on the 7.3 and see for yourself.

Hopefully you are using your 4.30 towing something heavier than the incredibly massive house on wheels that Gazilla is using his dominating mechanical advantage for, ROFL.

LOL.
Lets see some proof of those real world numbers.

You don't believe the 7.3 makes over 80% of its torque at 1500RPM onward? Do you trust ford or do you think you want a more credible source?

Peak is correct but the rest of the chart is misleading. Torque = HP x 5252 divided by RPM, when you do the math 100hp at 1500 RPM like the chart shows doesn't come out to 80% of the engine's peak torque at 1500 RPM.

If you line up the graph at the mid point of the number 100 you will see at 1500 rpm the HP is a bit above 100. But let's use your understimation, approximation of 100 hp, 350lb-ft at 1500 rpm is 74% of the peak torque and way more than enough to keep a 3/4 ton rolling down the road.

If you can't keep a lightly loaded F2/350 going down the road with that kind of torque between 1500 and 1700 rpm, then it is user error or mechanical issue.

Either way it's still irrelevant, you aren't making the max torque for that RPM unless the throttle is wide open.

A torque curve that flat is irrelevant? LOL. Whatever happened to your wild accusations of "false numbers"? Did Ford make all this up just to screw with you? In the old days people had enough sense to not accuse others of lying unless they are sure. You don't seem to have that sensibility or decency but, at this point in time, it's exactly what I expect from you. I expected better from someone flying the Battle Flag.

Like I said, if you find that kind of torque challenging to work with without the aid of 4.30, it's a user problem, not an equipment problem.

So you can't move max load beyond 1800rpm with a diesel?

Ok no proof of the torque numbers you stated, now lets see the proof of you getting 18-19 MPG.

Sure you can, why would you ask a question like that? I think you are confusing peak torque RPM with max RPM, they aren't the same thing.

Torque numbers are on the chart by Ford, if you don't like it, take it up with them.

My MPG numbers are what I calculated. There seems to be nothing others can say that you won't dispute if it doesn't align with your personal experience, whatever reason it may be.

If you are going to continue to call strangers liars even when given numbers, then I will say it here: You are a disgrace to the flag, and should learn to drive properly.

If you are making peak torque at cruising rpm that means you do not have ANY MORE POWER AVAILABLE than what is available at cruising speed. That means if you are climbing a grade you can't climb at a higher rpm than cruising speed rpm because that is where peak power is made. More rpm will just get you less power. If you made peak torque at 1800rpm you wouldn't be able to accelerate beyond 1800rpm climbing a grade.

Re-read what you are saying multiple times. I dont think you even understand what you are saying.

That's not at all what that means, peak power is made at a higher RPM than peak torque.
