1: Go on the highway and put on cruise control at 80 and tell us your RPMS
2: get a tuner
3: Get new gears from Mustang Parts & Performance - American Muscle It can cost up to $600 for everything from my research
4:speed isn't the deal, it's more for acceleration.

Thank God you came to the domestic side. Props to you, welcome to Modded Mustangs. Hope this helps some.

 

its already quick...just enjoy

 

1. how do I find out what rear ratio I have .
you have 3.73's

2. Whats up with the top speed and is there a way or would there be a way
to make top speed faster.
Your top speed is fast enough, faster than your car will let you go with the limiter.
3. If I have a 2.73 rear ratio how can I change that and how much might
that cost me.
You dont

 

Um...

The standard 2.73 rear axle provides an ideal blend of cruising fuel economy and acceleration, aided by the wide ratio spread permitted through the use of six forward speeds in the gearboxes. Performance enthusiasts can select an available 3.31 rear axle ratio for better off-the-line launch characteristics.

Thanks guys don't get me wrong It feels real quick But I'm guessing the mustang is quicker then my 2007 4 dr civic si I had clutch headers intake exhaust flywheel even If I have a 2.73 ratio

 

You don't have 2.73 bud.

 

I didnt get the performance package my stang was around 2300

 

But is it a lot slower in the quarter mile and what exactly do I need to order for the 3.73

 

Order Ring and pinion and install kit , Make sure it says for the 7.5( your rear size) Have a someone install it for around 300. Whilte your playing around with the rear get a posi diff if thats 11's dont have that. Also look at 3.73 vs 4.10 gears

 

tbh u should post this in the 05+ section lol

in search of specs i priced out a new mustang, with tradeing and a small down payment they are only 300 a month.. thats pretty cheap actually.

 

Thanks guys . so do you think I should still be in 14s quarter mile even if I have 2.7 rear ratio

 

what track do you go to?

 

I'm pretty sure southfour was right.

 

you do have a 2.73 gears lol...that's how you get the high MPG :yes

 

I bet if you went from 2.73 to whatever else is being suggested, It would make a huge difference.

But be warned. It WILL Change your mpg Not by much from my understanding, but it will.

 

happy to have found this web site answered all of my questions I live in miami so need to look up a mechanic in my area and I'm going to order the parts online just need to make sure exactly what I need : } Thanks again everyone for the info

 

I'm planning to run at the track in homstead florida once I break it in . so I do need a tune once I switch the gear ratio how much does that run for . Im really happy with the car it seems alot quicker then my 4 dr 2007 si but the onlt complaint I really have is that top end speed my civic was pushing 125 130 stock .

 

so I do need a tune once I switch the gear ratio how much does that run for .

I recommend picking up a handheld tuner from AmericanMuscle.com. PM AMStanger here and she can get you a discount code on all their products (AmericanMuscle is good to us here at MM). The tuner itself is ~$380 (I recommend the SCT). Get the one that comes with free tunes for life. It's great for getting retuned for basic bolt ons (they don't tune for internals, FI, or nitrous).

 

top speed doesn't really mean much, if you are racing its all in the takeoff. Do you have an auto? if so a tuner would probably help you out a lot, im not sure how much with the new cars though. but yeah you need one to fix your speedo/tach after you switch out the gears.

 

guys please stop confusing him lol

YOU HAVE 2.73'S AND AN 8.8INCH REAR AXLE

 

isnt this your 2nd thread asking these questions OP?

and yes there is a noticeable difference between the 2.73's and 3.31's. if you wanted a gear swap to 3.31's all you really need are the 3.31's for the 8.8in and have a shop put them on.

 

I bought 3.73 gears and the tuner cant wait to put them on : p found a mechanic that will do it for 200 labor do you think that 3.7 is better then the one ford gives 3.31
