AODE rear gear ratios

[LukeDaddy]

Just wondering what gear ratios you guys with AODE cars with are running? I know tire size equates to a lot of it, and my 285/35/18s come out to right at 26in tall... a 275/40/17 equates to about 25.5in, so they shoud be similar in comparison.

What ratios do you run, and what kind of RPMs do you turn at both 70mph, and at the stripe in the 1/4?

 

[sage2k]

3.73's and at 70mph its roughly 2300rpm

 

[Mrgreen94gt]

4.10 and 255/45-17 (26.035")

I think I'm just under 2500 at 70mph. I'll check later.

 

[HISSIN50]

3.55s on 245/40/17's and 65 MPH is ~2200 RPM (70 MPH would be slightly higher obviously, but this was one spec I recalled and I did not want to extrapolate numbers).

Ok look, I'm gonna give you some very good advice for your car. Don't do anything less than 4.10's. Seriously, you will hate it if you don't. Trust me, I started out the same way, not knowing. Well, I went with 3.73's and at the time they were cool, but when I went to the track with heads cam and intake and a 3000 stall with 26" ET streets, it would bog its ass off the line. I mean bog, like to the 60'. If I would have had 4.10's and something closer to 3800 stall, the car would have been sick. Our cars are heavy and the tranny gearing sucks compaired to 5spds, so we have to compensate for it. Take it or leave it

Thats the kind of advice I was looking for... I currently have a H/C/I on the car, and a TCI AODE, with shift kit...

I figured the wide ratio tranny would be well suited for 4.10s, but I wanted to hear "real world" advice from someone who had used a couple different gearsets... btw.. what kind of ETs did you see in your car?

Great advice for someone really into haulin. I would note that I am of the mind that (and I am in a HUGE minority) I dont like as much gear. Billy has some sound advice if one desires what he does. If it is a daily driver type car, I personally prefer less gear. I can keep it out of OD till 45 MPH, which I like around town. And on the highway I dont get droned to deafness.

We dont know what Luke Daddy is after, but I do like to offer that counterpoint, as it is a not a common one at all. I am pretty sure that a decision close to Billy's will be made though. But if people just searched old threads, it would seem like everyone likes 4.10's and nothing else.


EDIT: LD posted while I was feeding the dog. It looks like I was right though.

4.10s are a must for AODE cars.

Very good advice indeed

IMHO, your advice about the expectations of the original poster is WAY more important than the technical advice.

I usually try to ask folks about their goals, plans or expectations for their car when they post these kinds of threads cause as you pointed out so well, we all have different ideas of what a successful combo is.

On threads like these, I've about got to the point of offering no reply instead of starting out saying something like, "Well it depends on what you want".

Thanks for the confidence Grady. Since I am one of 5 people on here who actually likes numerically lower gears, I feel the need to say something. And I HAVE to say something if anyone, at any time in the thread, posts "Don't fear the Gear" - a phrase I cant stand.

You are very right about the user's needs being more important than the replier's opinion (which is not to take anything away from Billy's sound advice). But everyone likes lots of gear anyhow, so no one agrees with me (seriously, one guy on here does).

I dont post on the gear threads much either (I dont want 7 pages of email notifications per thread), but since I could offer RPMs and speed info, I felt compelled to post.

 

[LukeDaddy]

To acknowledge Grady, and Billy... I havent yet decided if I want an all out draggin machine, or more of a street warrior... I will see the track often, and do a lot of street racing... but moreso I just want to have fun.. which is why I asked what rpms, people turned at the stripe, and at 70mph, because this can give me some pretty good info as to how the gears affect the car... Ill base my decision on that info...

I do have a H/C/I on the car, and a single stage nitrous system, but Ive also got a powerdyne waiting to go on.... so Ill take that into consideration as well...

Thanks for the good info guys..

If it's not too late to throw in another opinion.....

I have H/I/blower daily driver with AODE and 3.37s as of now. With a 315/35/17 tire out back I'm running 2300-2400 around 70 mph.

Personally, I hate spinning the engine that much on long highway cruising... which I have to do a lot.

Since I do not take my car to track often, I'm actually going back down to a 3.27 gear ratio to get some of my overdrive back. Plus at the moment, at WOT I hit my rev limiter before the auto can 1-2 shift.

Once my car is not a daily driver, AND I want to invest in tuning devices to modifiy my shift points with the AODE, then I'll go up to some 4.10s.

 

[LukeDaddy]

Thats good info... Our combos are VERY similar... thanks for the advice...

Ok, not to get on anyones nerves here, but this is why I make the decisions that I do. Why buy a V8 mustang if your not willing to pay the higher gas consumption of it? They were made to be fast and noticeble. Why put a 3.27 in there if what it really needs is 4.10's? It will never be a 30mpg import, so why try to make it like one? Why put quiet and restrictive exhaust on a car that needs open and less restictive exhaust? See what I am saying? I give my car what it needs to be at the top of its game all the time, and if its open headers and 6.33 gears, thats what its getting. I don't see the point of putting money into something without makeing it the best it could be. Trust me, having 4.10's in the car isn't like haveing an all out drag car, it see the potential of it. Anyway, just wanted to say something, I wasn't going after anyone so don't get all defensive. BTW, my car ran consistant 12.9's @ 106 with the wrong gear and converter. I wish I knew what I know now, that motor would have freaking screamed for an AODE.

I did not see an overwhelming concern for fuel economy on this thread. Some folks dont want to turn high RPMs for ancillary reasons, like increased motor wear, NVH, etc.

I agree that these cars are not fuel friendly, but I dont think that was anyones' primary concern.

Gear choices are very subjective and individualized, which is one reason one can't beat the best choice into someone, because there is no one best choice.

I see and understand your point of view.

If that is what you want from your car then I think thats great.

I guess JT and I just wanted to point out that all kinds of folks are here on this site who are looking for things from their car that might not fit in with your plans for your car.

I know you are new to this site but you don't have to worry about getting on anybody's nerves, as you call it.

For the most part, everybody is usually pretty easy going and you'll find there is not much friction between peeps here.

Its all good and welcome to the site.

Grady is my personal diplomat. Grady, that was very well said, poignant, and I fully concur.

Voicing one's opinion is cool and makes these threads fun (more so than some of the cookie cutter boring threads). We all respect each others' opinion - Michael Yount (a very highly regarded member here) said it well when he referred to it as a 'Mutual respect community'. We might not agree, nor have similar goals (which in and of itself is, of course, going to create differing advice), but we respect each others' opinion and thoughts.
