nope your dead wrong there, mustangs are ussually limited by the limited amount of power they produce, not bc they redline...

if anything the 4.10s should increase your top speed.

gears cannot and will not increase top speed.

okay...

for example...

take a stock 5.0

w/ a stock t5 transmission

5th gear has an overdrive of .675
and w/ stock rear end gears of 2.73


thats a total multiplication of 1.842...

now switch your gears to 4.10s...

.675 * 4.10 now equals 2.767....


now you have more available torque

max speed at redline w/ 4.10s is 160mph...

max speed at redline w/ 2.73s is 240mph...


BUT WAIT, the stock 87-93gt top speed is about 140mph...that is because it is limited by power, not gearing...

and with the 4.10s it will now have more torque allowing it to reach a higher speed....

understand?

for any given rpm the car with the higher rear end gear will be moving slower.. so just to maintain the same speed as the other car the higher geared one will already be spinning its engine faster....
gears help you get to your peak torque faster.. once you get there its all downhill.. the geared car will hit the proverbial wall (where the torque and power available will no longer be able to provide acceleration) before the stock geared one would thus lower top speed

you have a lot to learn about cars my friend sorry...


gears ARE NOT used to just hit your powerband faster..that just plain wrong... do you even understand what torque multiplication is?

I have 4.10s in my car with a traction lock and i can get up to 120 easly and it still has more. I was at about 4500 rpms doing 120 and i got there pretty quick.

ok so the 50 times ive heard people say that gears help you get into your power band faster over the past 9 months have all been wrong and noone has ever corrected them?........ i find that hard to believe

and yes i do know what torque multiplication is.. im kind of studying to become an aeronautical engineer and am taking engineering courses that deal with torque

keep studying man!

the reason you buy higher gears is for torque multiplication not to get to your powerband faster...

well i still disagree with you that higher gears give you a higher top speed.. hopefully someone can explain this all out so that we'll know definitively who's right and who's wrong....

please look at my example,

like i said, there are many cases where higher gears will yeld a higher top speed...

not in all cases though

torque is irrelevant to topspeed.
unless you increase the horsepower of the engine, it will not be able to push the car to 240mph. or 160mph. i dont care what gears you put into it.

when pushing for top speed, you either run out of gear, or you run out of power. it's as simple as that.

understand??

that's just what he does.

if someone says something that he doesnt like, he just posts a bunch of numbers and random data and declares himself the winner.

resistance is futile...

alright, i tried to help you guys, you can run your stock gears and think your fast...

at the end of the day ill have the faster time slip so whats it matter to me??
