Ratio's

[drew442]

I thought we'd start a thread of gear ratios in different box's so people know what theyre putting in their cars. Actually i wanted to know what the difference was between the 0506 that i took out of my car and the T5 i just put in but i thought a reference thread would be a good idea as it would help out more people.

I'll kick it off with a quote


For the T5 gearbox...

1st is 3.47:1 50 klm
2nd is 1.96:1 85 klm
3rd is 1. 26:1 130 klm
4th is 1.00: 1 170 klm
5th is 0.79: 1 175 klms

reverse is 3.37:1

Thanks NIGHTHAWK. thats the only info i could find already on the forum. anybody got a workshop manual?

Post auto ratios too guys...

[drew442]

cant elaborate more ford_man? which 4speed is which? casting numbers or engine/trim combo? or compliance plate code?

[SIR]

what is the diff ratio used with a 3 spd auto . I have an xf ute with auto 3 spd & 3.23 diff .

[drew442]

i dont understand the question. its not front wheel drive so the diff and gearbox are seperate items. you can have whatever diff ratio with whatever gearbox you like.

if your speedo is out you need to replace the speedo drive gear.

You need a brown drive gear

[SIR]

I thought there were different diffs for auto's and manual , ute and sedan . my ute sounds like it's reving it's balls off at 100km tacho reads 3000rpm , is that normal . Maybe I've just got used to late model cars .

[82falcon]

For a stock 3.3 300rpm will be revving its balls off. thats just the 3.23 diff andno overdrive

thats all i have


is the last part meant to be XE/XF? also wondering if the quoted post could be made into a thread and stickied... took me 30 minutes to find it :lol:

[XF0747]

i need to get a speedo gear for mine

[On Da Ghia]

Replacing my auto with a T5 now sounds like the best move I made!

Auto)))))))) 2.39----------1.45----------1.00
T5)))) 3.47 --------1.96---------1.26----1.00------0.79

Can't wait to get the 3.45's in the arse!!!

P.S. great thread Drew, this should be a sticky for sure
Christo

[XF0747]

thing i dont get thou, got the correct speedo gear from ford to suit my car and it still wasnt the correct one

[robbie]

what ratio are you running george?

[XF0747]

3.23

as i said i got the gear from ford, went to put the tailshaft in, and the speedo gear had caused the output shaft to sit off centre, ripped the speedo gear out and the tailshaft went in with no issues

[xeghia302]

does changing diff ratios put the speedo out? never thought of that. Might be a stupid question, not even sure exactly how the speedos work

[XF0747]

yeh will put speedo out if u change diff gears

[drew442]

so the speedo gear physically doesn't fit?

are they giving you the gear for the right box? what box is it?

maybe best to ask KEAS who i assume built the box?

[NO.PSI]

I need to get the right one as well.
with my 3.89 ratio, my speedo sits on 160kmh's when i think i'm doing 100.

[XF0747]

yeh right gear for the right box, its a c9, paul had to get the gears from america, and its hard to get in contact with him also

[drew442]

you can adjust it electronically too.

http://jaycar.com.au/productView.asp?ID=KC5435&CATID=&keywords=speedo&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=

might be the go for both of you.

[XF0747]

i actually got no speedo gear in it atm

[eddie351gt]

so correct me if im wrong, if say the speedo is out by 20kmh (doing 80km while the speedo is showing 100), and the diff ratio has never been changed but the transmission was replaced, would i go for a speedo gear with more teeth? or less teeth? and is it one tooth more = 10km/h?

sorry my brains farted and i cant get my head around it at the moment lol

[drew442]

you should have swapped the gear over when you swapped the box. get the ratio off the diff tag and go and order the right one.

[eddie351gt]

they'll know the right one to suit?

i think its a 2.92 diff, Bw35 auto

[JOSH88XFUTE]

Hi could you help me out i have an XF ute with a 3speed manual running a 2.77:1 diff and the speedo is out (20k's) the sender unit has a green gear on it with 21r-da on it could some one tell me if this is right or if not what i need to change.(Im guessing the sender but do i change the whole sender or just the gear & to which gear do i change?).
Thanks

[lowxdute]

T5 is not quite those ratios listed but close.
86 XF Series 2 onwards up until a ratio change around EB2 or later. XF/EA T5=
1st 3.50:1
2nd 2.14:1
3rd 1.39:1
4th 1.0:1
5th 0.78:1
Cheers,
ZAC

[beaver700]

Gday,

Just a question about speedo gears,

If I have a t5 with a 3.08 final drive, what colour speedo gear will I need (or part number), and where can I get it from?


Cheers

[drew442]

thats not an xfalcon ratio, thats from an e-series yeah?

just ask at your local ford dealer, let them know the diff ratio and that its a 5 speed, i think the t5 and the btr 4 speed auto are the same speedo drive anyway.

the other option is the speedo kit from jaycar to adjust it without changing the speedo gear.

I think a 2.92:1 speedo gear with bigger wheels than normal like 17 or 18 in wheels would get your speedo fairly close to correct . 2.92:2 gear is purplewith 18 teeth . good luck son .

[Spak2Spak]

Yeah i think everyone is forgetting about tyre circumferance aswell

[lowxdute]

Well when people state their setup they should include ORD. Standard tire/rim combos ran on xd/xe/xf's series is anywhere between 24.9-25.5" Running the correct cog with a tire/rim around 26" (eg; 235/60R15) should provide near spoton readings as ford speedos tend to read slightly under the limit.
ZAC

[ianp]

Are they the same speedo gears for cable operated speedos as they are for the electronic ones?

I have been thinking about getting a 2.77:1 for the XC but not sure they would have a speedo gear to suit.

['Nova]

RATIOS AND REVALENT REVS @100 km/H with a 650mm/25.6" ORD tire/rim combo:

2.77:1 revs about 2260rpm @100 in 1:1 (top gear)
2.92:1 revs about 2390rpm @100 in 1:1 (top gear)

4.11:1 revs about 3360rpm @100 in 1:1 (top gear)

trying to get my speedo right, thought this should be in here too so people can figure out what diff they're running if they have the same issue as me (i've got an eb diff but some soppy ****** decided to remove the id tags.. and i couldn't remember all the details from when dad rebuilt the diff for me)

thanks to lowxdute for providing the information

any chance of getting this thread sticky'd? i ask before, but it managed to stay close to the front page anyways :P

EDIT:

just got off the phone to tilfords, the item i need, being a 3.50:1 8 with 23 should make it Black, they're telling me that they're yellow.. so now i'm a little lost anyone have any ideas..? should be right if its got the teeth but.. thought i should double check anyways ;)

[mrfordfairmont]

help i have a xd with 2.77 diff what gear do i need as the blue one is 20kms out

[staids]

any chance of getting this thread sticky'd? i ask before, but it managed to stay close to the front page anyways :P

Done Alec..:hy:

[xf falcon tunna]

i running 4.89 .mint

[Squiggs]

my xf ute has 351 and 4 slot single rail in it with 4.11 diff gears, what`s the best way to correct the speedo??

[grabber]

What about FMX and 3.45?

Regards

m

[Duffy]

Yeah I got a 3.45 diff and mines up by bout 20km installing a c4 this week apparently u can't change the gear in that. It's welded on or some shit (no idea how that works just what I was told) whats the go

[ToeKnee]

What speedo gear would I need if I've got a 2.77 diff and now a four speed gear box. All in and out of a xe. It used to have auto and now the manuals got a purple speedo cog
