rear-end gears affect RWTQ? despite searching i was unable to come up with a reasonable answer.
Q: on the stock 10-bolt, will swapping to a higher numerical rear-end gear affect your measurements at the rear wheels?? (i.e 3.42 > 4.10)
last weekend i had my car on the dyno, i informed the operator that i had different rear-end gears so that he may make any needed adjustments.
his words, well it might make your torque reading somewhat off.
which to me seems pretty vague.
anyone have any clarifying answers? my buddy who was there with me seems to think my that my RWTQ is a lot higher than to be expected.
but my friend is also an idiot, and really has nothing to base this on other than what the operator mentioned. and is going around saying that those arent the "real" numbers.....

The gears won't effect numbers on the dyno except for maybe giving you a little if any drivetrain loss. The gears usually show up on the street or at the track in terms of multplying the amount of torque you getting to the ground.

You may lose a few lb/ft of tq. Nothing more than 5 lbs with a numerically higher gear. The dyno operator seems a little uninformed.Nate

thanks for the response guys, thinking about it in my head, it just didnt make sense that i would be making MORE power at the wheels (i just needed confirmation)
no i can tell me stupid friend to shove it.
but im still wondering how exactly it works, does anyone have any detailed explanations..??

It is torque multiplication. Imagine trying to ride your bicycle up a really large hill. You put it into a lower gear to use torque multiplication so that it is easier to turn the tire but requires more rpm to go the same speed.
Here is a page that will let you calculate speed and rpm from gearing and tire size.

i ment more along the lines of equations, figuring for actuall drive-line "soak-up" and how i can actually calculate it myself.
i appreciate it though but i know allllll about that
