Just ordered my 3.73's...
Well, I finally decided to fear the gear and order the 3.73's. Not really worried about the difference in 4.10's and 3.73's as Im only 17 and dont EVER race the car. Just needed a little more pick up in it. Now for my tech question. When you guys had your gears installed, does the installer usually provide the bearings and such, or do I need to purchase those on my own. Thanks guys...cant wait to get these suckers in. :D

Prepare for god awful highway trips. ;) |
Dont really do all that much highway driving. Wont mind it too much, if I do, then oh well. Mostly just a city car.
|
I have found 4.10's to be great for city driving. 3.73's are a good option too. I went with 4.10's as my Mustang is a third car. If it was a DD, I would have chosen 3.73's.
|
Yea Im going to be doing more hwy driving next year as Im going to be driving to college every morning (near home) so I dont want to be too bad I guess, even though I hear the 4.10's arent bad. Now to just get these things in and installed.:D
|
I'm just going with 3.90's and calling it good :)

Yea, my car has almost 70k on it so bearings are a must. Thanks

Matt:
Sounds like you made the right choice in gear selection for your needs. Someoen suggested 3.90's! I never understood that gear. Just get 4.10's and don't look back. Afterall, there really is not much of a difference. |
I would have gotten the 3.90s if FRPP racing made them, but they dont and I dont trust Motive enough. I dunno, just weird like that. HINT HINT FRPP!!!
|
gear
i went with 3.73s but wish i could have found a good 3.90 i just didnt trust motive either i went with richmond
|
I am planning on getting 3.73's this week beacuase I still do some highway driving I just want a quicker take off and more power to pass
|
Yea thats exactly what I was looking for. They also came in the mail today :D!!!
|
I just had my 3:73 gears put in what a difference wow!!!! Makes the car a blast to drive
|
Awesome man, you make me feel a little better about them now. So the pick up feels good?

The pick-up is much better now. When I step on the pedal it blows by other cars now. I think its a good investment for any mustang and maybe it should be the first |
GREAT. I cant wait to get mine in.
|
hey matt, where are you getting them installed..b/c im also in the sc area and dont really know of a good installer(basically why i havent bought any gears yet)
|
Well, there are some family friends that I may be able to get to install them, but right now, there are no concrete plans. The one place that I thought installed gears doesnt put them in, so the search somewhat continues. Call your local ford dealer, Im sure their service techs can put em in for you.
|
i rather find someone has installed plenty of gears on mustangs..ford has a knack for charging too much...im thinking of this one place in columbia, i also know of this other place in murrels inlet, i may just call and get some estimates..thanks though
|
Where were you thinking of calling for the install? Just want to get these things in.
|
You will like your 3.73's on the street. Really wakes the car up. They did not affect my mileage at all. If you went with the Ford racing gears they are easier for your mechanic to install. Ford uses something they call the MHD which stands for the master housing deminsion. Every set of gears uses the same backspacing so there is no need for measuring back spacing. They still need to check backlash but this does help speed up the install. My 3.73's were Richmond's I replaced them with a set of Ford Racing 4.30's and the 4.30's are much quieter.

the other one is on huger street in columbia ...i would have to look around to get the name and number.... |
Well I called the one on Huger, I believe it was Muffler shop of Columbia, and the guy told me they didnt install rear end gears...I was like WTF mate?
|
damn, well, im suprised...try carolina car creations...i will check and make sure that is the right name...my friend got gears installed awhile back on his camaro..
|
u could also......try ats performance on devine i believe
they are mustang devoted and if they cant do it, they can refer you to someone..and they also have a dyno :) |
ATS closed up shop I believe.
|
Im going to call that muffler place back and see if they just had someone one the phone that didnt want to talk at the moment. Ill get back to ya.
|
alright..thanks

3.73 gear no joy
Just woundering what is wrong with my car? I had my 3.73 installed along with my BBK CAI, underdrive pulleys, K&N air filter, and tuner from Super chips. My car was running 14.2@98mph 1/4. before the chip and gears now I run 14.4 and the cars idle is off. What are some suggestions.

Two things: 1st, you may have done too many things to your car at once. As a result, it is difficult to pin down the problem. Second, you are not the first guy to post slower times after a gear swap. It is harder to drive the car with the 3.73's than the stock gears. As you practice, the times will improve.
Also, be sure to compare you DA's. Your 14.4 may be faster than your 14.3 when corrected for altitude, temp, and humidity. Then again, it could be even slower. When you say the idle is off, what do you mean exactly? I may be able to help better with some details. As modded, your car has the potential to run in the 13's...even mid 13's, so stay with it, practice, and let's see what is going on with that idle. |
tuners/programmers are programmed for stock cars, so the other mods may have thrown off the tune a little. The best bet for a modded car is to get a chip burned for your mods...better yet get one that will adapt to future mods. Some tuners like Tim at Modularpowerhouse.com set the parameters to give you some room for more mods. I know he gives you the ability to add 25 hp before you need a retune.
|
His mods do not require any custom modifications except for the gears. Any mail order tuner with those mods would not make the tune any different than if the car were stock. Even if it were dyon tuned, the improvement might be only 5 - 8 hp.
|
What was your 60" for both runs?

His mods don't require a tune, but he got a tuner to try and get more power. Any good and reputable tuner could get more than 5-8 hp, which makes me lean toward a dynotuned chip for the same price. What I was trying to say about the programmers is that they are designed for a stock mustang, so you will see the best benefits on a stock car. There are many more parameters in tuning, and the programmers are very generic when it comes to that. This is why a chip specifically set up for your car is the best bet all the time. And BTW, modularpowerhouse gets some decent numbers out of stock or close to stock GTs with their tune. |

It's kinda far for me to drive from Delaware to N.C. so I'll probably find a dyno shop in the tri state area. I've had one dyno run already and with out the gears and tuner I pulled 244hp at the rear with about 300fptorgue. The dyno guys said that it was pretty good for all engine and being a automatic. I wasen't happy because it didn't sound right to me. I really just want a dyno tune for ****s and grins. I know at the track is where my times matter. I'm setting a good base line for now. In march I'll be going with a supercharger. Kenne Bell or procharger? What would be a good foundation to get. Someone give me some good input

Well, Stangdude, the gear choice is really dependant on what blower you end up with. Most people say a max gear for the Kenne Belle is a 3.55 gear due to traction. With the centrifugal supercharger, go with the 3.73's. Good luck, and thats really not a bad baseline. What are your mods?
|
is it true that these gears will shorten the lifespan of your engine?
