Whats the difference of 4.10 and 3.73 Grears?
I'm looking to change the gears in my V6. I have a 2001 Manual 5 speed V6 Mustang and I want to know the difference between the two gears 4.10 and 3.73. and is there any other mod I should have done with changing gear ratios? I would just like the fastest take off I can get.Thanks.

I can't say anything about the v-6, but 4.10's on the GT are great. I have no regrets and the fuel economy is about the same as with the 3.27's.
Gears do not suck up gas, load does. So, just because you are turning more rpms, does not mean you are using more fuel.
Also, when I had stock gears, I would always have to downshift to 4th on the highway a lot. No so with the 4.10's. But, the 4.10's are soo much quicker, you always want to nail it. They really make the car more fun to drive....and that I am sure might cost you at the pump.

Nope. I did not contradict myself, though it may seem that way.
Load and rpms are not the same. Just because your car is turning at higher rpms does not equate to more fuel except for a little bit of extra friction.
Load is how much power the car is making. If you are driving your car at 3,000 rpms going 50 mph in one gear and switch to another gear and go 50 mph at 4,000 rpms and keep the car at the same speed, it is not taking more fuel. In both instances, it takes the exact same amount of energy to make the car go. The weight of the car, the amount of rolling resistance, and wind resistance are consistent in both situations. The only thing different is the amount of internal engine friction.
What I was trying to show was that there really is not anything magical about gears that result in a loss of fuel economy, but I think drivers tend to run there cars more agressively when they have them.
Additionally, if you talk to most drivers who have made the switch they will tend to say that they experience the same fuel economy or loose about 1 - 2 mpg. For the most part, I think it is up to if the driver changes his driving habits with the new gears.

true and its hard enuff that our engines run up to what like 6200rpms.... theres no way in hell they can hit 18000rpms lol not even my bike can do that.....dumbass...it had to be a v6 guy lol

I pretty much agree with Blake on this but I did a little diggin to see what I could come up with about gear changes and what happens to fuel economy.
I found on a couple other forums,(one of which was a truck forum for people who have tow vehicles) a couple replys to a similar Q was that switching from 3:73s to 4:10s would result in roughly 10% decrease in mileage runnin down the highway. Less load on the motor would increase your mileage in stop and go driving by that much or slightly more. I guess its personal preference.

Hum, top speed and gears? Theoretically, your top speed will decrease by going from 3.27's to 4.10's.
Imagine if you could go down a steep grade for as long as you like, so the car is capable or being speed limited only by engine rpms. In this instance, your top speed will drop by going to 4.10's. It is a simple fact of life. In 5th gear at 6,000 rpms you will simply not be traveling as fast with 4.10's.
In reality, with 4.10's in 5th gear, you are higher into the power band and able to overcome wind resistance better than at the same speed at lower rpms with 3.27's. While I have never seen how fast my car could go before or after swapping gears, I have talked to people who have and they claim that their car actually achieved a higher top speed with 4.10's, but not by much.

Crap, Dustin and I have not agreed on things before. We always get through it. - LOL
Actually, if you read my post again, I was really not arguing with him. He is technically correct. Top speed should drop with 4.10's and it does if you are not taking into account wind resistance. In truth, I have never actually seen anyone do a top speed check before and after a gear swap, so I am merely speculating.
