Bear with me people, and gear heads speak up please.

After reading up on all the great informational threads and articles on this topic (especially http://www.mustangevolution.com/forum/t158093/ ), I'm wondering if I'm interpreting this seemingly simple area of auto mechanics correctly:

A lower gear ratio (e.g., 3.31:1) results in relatively more transmission focused torque (and relatively lower engine/RPM work.)

A higher gear ratio (e.g., 4.10:1) result in relatively less transmission focused torque (and relatively higher engine/RPM work.)


I'm not trying to draw any conclusion about the ramifications of different gear ratios on an engine -- just further my understanding of said topic. After all, I've been told "don't fear the gear" - and the first step to that is being in the know.

Thx.

P.S. I hope I don't have this all ***-backwards.

P.P.S. I suppose this could've been posted in a more general forum section, but it is with intentions of applying the knowledge to a possible mod on my (2010) vehicle at some point.

The 410 is the lower gear and will give youi more bottom end over the 331's. 410's= dragstrip, 331's= Bonaville Salt flats.

Ok. Maybe I got that part ***-backwards. Or did I?

After sleeping on it, and thinking about the post, I'm editing to say:

But I didn't say "A lower gear results in a ... etc."

I said "A lower gear RATIO results in a ... etc."

Isn't 3.31:1 a lower ratio than 4.10:1 ? The same "effective" gear results, sure (i.e., 1st, 2nd, 3rd, and so on), but the transmission ratio to the rear axle has changed.

I was thinking the more times the driveshaft needed to spin in order to complete a tire rotation would mean a higher gear ratio.

Please clarify?

And what of the resulting transmission torque v. engine work on different gearing ratios?

This part I get - yep - made full sense before I even had my question.
