when the engine spins one full rotation the diff spins the wheels 4.10 times (stock) but with the gears it will spin 4.57 times per one engine rotation approx.

You have your numbers backwards Spec Ops, for you would be going for top speed. Also, there are ratios for each gear you didn't take into account. Now if you said for each time the driveshaft spins 4.57 times the wheels spin 1 time, then you would be correct. Imagine a picture of the ring and pinion, the ring has lots of teeth, the pinion has few.Anywho, no harm done.
By all means some one correct me if I'm wrong.
I'll fix it

There are 4.57 ring teeth for every pinon tooth. That's the actual definition involved here.
His original "typo" was wrong about the driveshaft being 1:1 to the engine, wrong about the ring being 1:1 to the wheels, wrong about which way the gear reduction works (he had it inverted), and wrong about the relationship between torque and speed (he also had that inverted).

In other words, you gain no power but your wheels spin faster then what they would with the stock gears.
Like I said, so wrong it was scary.

It's not necessarily 1:1 for the ring and the wheels, either. That's the whole point of the differential, in fact. It allows the wheels to turn at different speeds, so obviously they can't both be turning at the same speed as the ring gear. If the car is going straight it *might* be 1:1, but I doubt it.

Even his "correction" still claims that the the 4.57 gear turns the wheels faster than the 4.10 gear. He clearly doesn't have a clue.

No the driveshaft is not 1:1 with the engine...there are transmission gears (as I said, I mean't to write it the other way)
the ring is approx 1:1 if the car is going straight....we don't need to be EXACT here nor do we need to account for the LSD.
The car gains "torque" (even though it really doesn't) because the engine is doing the same work for "less." Its like using a small pulley instead of a large pulley. Mechanical Advantage at work.
No need to give a somewhat rude response.
