I Fear Gears....

[Dusstbuster]

I thought that only the 99's and up you could use that speedcal... the older ones take the speedo gears (little plastic gears that slip in the side of the tranny)??

Thats what i'm confused on now. I got the speedcal but then after thinking and reading somewhere that said you can just buy a little gear for like 20 to correct it...I mean....how can an electronic device fix a non-electronic speed/odometer?

Speed-cal will work for a 96, Mine is a 97 and I have it for my 4.10's.
The highest speedo gear you can get is for 3.55's.

And my speedo is dead-on perfect.

 

[tomustang]

you can easily adjust your speedometer with a speedcal or hypertech or other brand programmer.

No he can't, that's a bs marketing ploy to sell programmers, ALL the options do NOT work with every year car, mostly the 96-98's

 

[tomustang]

It ruins the fact that the car has original miles in the first place.

You sound like you are going to sell the car after a bit

 

[stangGT97]

both the speedo gear and speedcal will work, but the gear wears out faster and like Outlaw said, they only go up to 3.55. Your Cobra is begging you for 4.30s, your car will be a whole different beast w/ them.

 

[blackfang]

The speedcal will work on ALL 94-04 5 Speeds.

get the speedcal and 4.30's

wait what now im confused????? Also... the higher i go after 3:55s the more its off???? And to answer tom, actually no but i dont want to tell the next guy (if i actually do have to sell) that the odometer is actually less than what it says, i know i wouldnt want to hear that if im buying the car. For some reason thats a turn off.

They dont mean the rear end gears would wear out faster. They mean the gear you'd use to correct your speedo instead of using a speedcal.

 

[tomustang]

wait what now im confused?????

your car has a mechanical 'speedometer' gear which is made out of plastic, since it turns more, it'll wear out quicker than the stock speedo gear

you just tell him (if you ever do sell) 'dude! it's got 4.10's or whatever, no one would care

 

[hotmustang331]

Dont be confused....look, ALL YOU NEED IS THE SPEED CAL.

You will love the 4.10s....and I would go to www.dallasmustangs.com and buy the speedcal so you can put it in when you get home....or have the shop do it and the miles will be dead on accurate.

 

[Dusstbuster]

Order the package from MustangTuning so you can get the gears, speedcal, and lube for a decent price. Then use the stangnet coupon code for another $17 off for a grand total of $52 saved + free shipping...at least thats what I did.

(although i also ordered the bearing install kit for 8.8" so it might not be $17 after discount, but still, it's a decent price)

 

[hotmustang331]

Upgrade that 5% "stangnet" code to "mustangboards" for 6% . I just found out about that a few days ago lol

 

[mransr]

mildly off topic

what is GTR charging for the install? if you don't mind me asking?

they charge around 225-250 for the install

Im ashamed to say it but i think it ruin my cobra, i dont like the whole odometer and tach reading differently afterwards thing. It ruins the fact that the car has original miles in the first place. It goes in the shop wednesday and i feel like calling GTR back and cancelling the swap for the 3:90s. somebody please tell me its going to be all right and that will not ruin the value of my beautiful car

My friend with a '97 Cobra has 4.30's in his and SWEARS by them. Says he loves them and it's not too high.

Oh and the answer to your worries is a Speed Cal. It will get your speedo and odometer exactly 100% right so no worries about adding incorrect mileage.

I would cance the 3.90's and do 4.10's at least. Those DOHC motors love to rev.

 

[96_SVT_VeNoM]

I already called GTR and switched to 4:10s.... as 4 how much, total its going to be around $2000 clams (gasp!!) but thats 4 Bassani x, Bassani aft cat, 4:10s w/ speedcal, bearings, PLUS new OEM cobra headlights (originals are yellowing ), snake for the grill (instead of OEM pony). All the lader I will be installing. I also ordered the K&N FIPK from work 4 $180. I have yet to talk to them about next week, which i plan to throw in a frpp king cobra clutch, and alum driveshaft, and MAYBE a triax MAYBE . I dont want to spend to much yah right.

All this in hopes of being in the 12s

 

[hotmustang331]

$1800 would be pretty fair....tell them not a penny more .

You could do the X pipe and catback yourself...VERY easy to do IMO. Save you a few $$$.

Don't get the 4.30s. They suck for daily driving. A close friend of mine bought a 96 with 4.30s in it. It sucks having the engine turning that fast all the time, especially on the highway. Going down the highway at 70mph he is around 3200 rpm, its just too much gear. Stick with the 4.10s if you want steep.

Umm I hate to break it to you, but your data is inaccurate. Besides there is a 150 rpm difference between the 4.10's and 4.30's.

I have had 4.30's in my Cobra for 3 1/2 years and its a daily driver and made 2 cross country trips. The car averages 23 mpg on the highway and I can around 22 around town.

BTW, at 80 mph the rpms are 3100 not 3200@70 so something isn't right with his car. Check to see if he has a speedcal and correct it, or if he has a speedo gear, remove it for a speedcal.

 

[MisterCMK]

My mistake, it was around 3k at 80. We made that trip doing 90mph that day.

Anyway, having driven the car, I don't like that steep of a gear, but to each his own.
