But I agree, your gearing relies heavily on where you live.
Sorry if you didn't like the example but chose that one because it can be quite polarizing, just like this topic.

It's like the old Auto vs Stick, bias ply vs radial, rubi vs non rubi, ford vs chevy, coors vs budweiser.....

Just trying to show there are other options and people should really look into it for themselves instead of mindlessly following the masses.

Not surprised.

Another example that you fail to understand. You need to learn to think outside the box and that might help to understand what I was getting at. In other words, stop being so closed minded on the subject.

BTW, was speaking to an engineer that works for NASA this last weekend and he said it is torque, not HP that is needed. Hmm, that's what I said as well. Sorry.

i also have a 09 unlimited with 5;38 and 37 nitto's and if you drive 68 to 70 and it not a head wind i get 15 to 16 on the road and 14 ish around town. it's not a arc car but better. i could tell a difference when replaced bumper and did away with the wind deflector under stock bumper.

Did your conversation with the engineer also address an engine's efficiency at certain rpm's?

Yes, torque is key. However, it's more horsepower that gets the work done at a faster rate.
You can gear a bicycle down (increase torque) to where you can pull a box car, but progress will be very slow.
It takes more horsepower (the locomotive) to do it at an acceptable speed.

A glacier can provide a lot of torque but it's pretty slow moving. Torque is momentary force and horsepower is it's application over time. They are joined at the hip.

To answer your first question, no.

As for your second point you will find many different opinions and support for each side just by doing a simple internet search.

Finally! It's about time you admit torque is a factor at least. I'm making progress. Not there yet but there is hope for you. We'll get you there. Persistence is paying off.
