Change final drive ratio...
OK, so I have this nice new-to-me 2.0 Mondeo. It's doing 4500rpm in 5th at
motorway cruising speed, and I'd much prefer it to be doing 2500rpm.
Any easy way of changing the final drive ratio? Is the same diff fitted to
any other Fords with a higher ratio? (Mk 1 Mondeo, 2.0 Zetec, from
1995/6...)
Also, after a Mazda and a Toyota, I've been sadly disappointed with the
number of toys on a 'GLX' spec - not even electric rear windows, not to
mention the manual sunroof and steel wheels....

Sure you aren't in 3rd instead of 5th (sloppy gearchange)

I'd expect the diff from a diesel to have a higher ratio but no data to back
this up- but you would possibly find it on the Ford website.

If he's cruising at 90mph, then it could well be 4500rpm. Gearing in some
modern cars are disappointingly low to get better 0-60 figures.

I never said that ;-)
The 0-60 is plenty good enough, I want low revs at high speeds :-(

True, but if they design a gearbox with close ratios 2,3,4, then 5th
must also follow suit or there would be a large gap in the ratio.
Also, it doesn't help when mad motoring journalists often complains
that high gearing is hurting acceleration.

Not too fussed about close 2,3,4 either - I just want a relaxed car. If I
want 'sporty', I won't get a Ford ;-)
I was spoiled by my Carlton GSi - nice torquey engine for a relaxed cruise
<3000rpm at 70.

Well yes, but I paid 300 for an N reg car in good nick with 50K on the

Are you sure a 2.0 Mondeo can actually manage enough power to maintain
motorway cruising speed at 2500RPM?

Sorry but to get that by changing the final drive ratio, you'll lose 0-
60 performance.

I do understand gear ratios, but thanks anyway ;-)
I meant the 0-60 can afford to lose some, in exchange for better cruising...

Then I'll change down...
It would have more torque at 2/3 revs than many smaller engines would have
at 4500. They manage...

Very roughly 15mph per 1000 rpm? That's '50s cars. You've got something
wrong.

I used to have a Mk1 2.0 Mondeo and it was geared perfectly normally for a 2
litre car. About 22 or 23 mph per 1000rpm from memory. Either your speedo or
revcounter are faulty or someone has fitted the wrong gearbox. The early
gearboxes did have a common synchromesh problem on third gear so it isn't
unusual for them to have been changed or rebuilt. Maybe someone got a cheap
second hand one from a breakers and it wasn't the right box.

I'd agree.
On my old 2.0 Mondeo, cruising (80) in 5th would be about 3200 rpm.
To be doing 4500 in 5th, you've got to be doing an enormous speed.
ISTR that red-line was 80 in 3rd and 100 in 4th.
There's definitely something wrong with the gearbox.
Looking at the MTX75 gearbox ratios (if I've found the right one - I gave
away my old Haynes manual), the ratio of 3rd to 5th is 1.45, giving a
cruising RPM of 3100 if you've incorrectly selected 3rd gear.
I'd check that you've got the right gearbox, and that all the links are in
good condition. 4500 at cruise in 5th in the UK is wrong. I assume it does
have 5 gears? If it's only labelled at 4, try putting it in 5th.
If it doesn't have 5th, you may have an old Escort 1.3 gearbox or
something!
Pete.

Or more likley his crusing speed is 100mph, in that case what does he

So whats that then? As others have pointed out, you're looking at
around 100MPH.

Exactly. And not only that, is the engine really going to be generating
enough power at 2500-3000rpm to keep the car going at 100mph?

If you make that 90, then it equates to 20 mph/1000. Not unreasonable for
a medium sized engine in a heavy car.

That's in the ballpark. Maybe it's not unreasonable, but I don't like it!
Maybe I just need to wait till I can afford a 6 speed :-(

I bet that, if you sat down with a pen and paper, and actually worked out,
taking into account the drag coefficient, mass of the car etc., the amount
of power needed to maintain a constant speed of 90mph on a flat surface,
then the chances are the 2 litre engine wouldn't be producing enough power
at the lower revs you'd quite like. If it's only going be coping at those
revs on a downhill stretch then you won't save any fuel as it'll be at a
much smaller throttle opening anyway, or possible on the overrun (i.e. no
fuel being pumped through at all), and obviously on any upwards gradient
you'd be wanting to drop down a gear, so it'd spend a *lot* less time in 5th
gear anyway. You want either a TD or a V6/V8 somethingorother! But you're
not going to get a low mileage one of them for 300, so just be happy with
what you've got :-)
Or you could try a Metro GTi, to see what low gearing *really* is.

For cruising, we're talking torque. Peak torque on most petrol engines comes
at around 2300-2800 revs, which is where I'd like to be at 85-90.
In practice, it's running at 4000-4500 which is irritating.

Oops finger trouble..
Alright, I give in, they've geared it just right, I'm being unreasonable.
Although the 2.0 Zetec does have 80% of it's peak torque from practically
nothing right to 5800rpm or so, it's surprised me like that.
Unlike the small Rovers which seem to have a torque band about 300 revs
wide...

Perhaps not, but if the gearing was higher you'd probably find you'd be
forever changing gear on a motorway.

The thing is, torque gets you there, but power (product of torque and revs)
keeps you there.

1) Why not cruise at legal limit 70mph, this will relax the engine and
driver, and other road users will also feel more relaxed by not having to
look over their shoulder all the time.
2) Get a better car.

No sadly just something wrong with the OP. It was a troll and he wasn't
talking about 70 mph at 4500 rpm. So he's blocked for wasting everyone's
time and if he ever does have a serious question it won't be getting
answered.

Indeed. With the cruise control set well under 90, my 2.0 turbo is
nearly on boost even on the flat at 3000 RPM.

Err no, I think you will find peak torque for your Mondeo petrol is at or
around 4000rpm. You dont mention which engine you have though..
If the gearing is too high the engine will have insufficient torque or less
than ideal torque to propel the vehicle at that speed and mpg will be worse
due to a wider throttle opening being needed.

It's the 2.0 Zetec 16V, the original not the Zetec-E. From what I can find
(the 'original' curves on tuning sites) it has a fairly flat torque curve in
any case.

That's very true. 'If'.
Since it will still pull well if I floor it at 85 in 5th, I think it can
afford to lose 'some' revs still.
But it all looks too hard to change it anyway, so what the hell. I'll turn
the radio up.

Thank you for your input.
Actually it wasn't a troll, it was a serious question. I *never* complained
that it was doing 4500rpm at 70mph.
Feel free to block me, but if you think that makes me disappear for
*everybody* then you have no idea how usenet works.

That was the old days. Modern multivalve engines have the torque much
higher up the range.

Yes, basically you can change the final drive. As I understand it, all four
banger Mondeos mark one and two can mix and match transmissions and what
not. The mark one 1.6, 1.8 and 2.0 have similar gearing, the TD is pushing
2,700 rpm at 70 indicated.
The mark two, hmm, Ford gave the 1.6 tall gearing, the 2.0 has short gearing
and I can't remember what the 1.8 uses.

I have to ask why you didn't pick up on these points when looking. Steel
wheels are mostly irrelevant and as for the pain of having to open your own

That's not entirely correct. Check out those cars to have been engineered
for a low 0 - 60 and some have _tall_ gearing... so as to reach 62 mph in
second gear.
It's more associated with many multivalve engines' relativly disappointing
torque output at low to mid range engine speeds and wanting mix-range
flexibility.

You may not. Actually you might improve it if you lengthen it such that
it'll reach 62 mph in second gear.

That's because it'll be a relatively modern petrol four cylinder Ford.

It's not that difficult at all. Find a scrapped TD...

any info.

I know the 2.0Si has shorter gearing than mine... must be a pig on the

It was a good offer and I needed a car that could do some serious miles. I'm
not so fussed about any of it, just comparing it to similarly placed models
in the Mazda/Toyota range...

It's around 15% taller in the gearing department.

I would certainly look at the mph/1000rpm as an important criteria when
deciding a car. My present car is a quiet and relaxed motorway cruiser,
yes only a 2.0L petrol engine. However, it does have a turbo.

That, erm, interesting I suppose. But not especially relevant. Cars can be
great on the motorway with low gearing, conversely cars with tall gearing
can suffer from "acme engine noise" versions two through seven, variations
of "background annoying droning" if you take my point.
It's useful, yes, but it can easily be changed.

If it's really busy and I'm in no hurry, I do that. Have to watch for HGVs

Originally, yes, I'm sure it was.
But thanks to the Joy of Bangernomics, I paid 250 for my Mazda (323F), 550
for my Toyota (Supra 3.0) and 300 for the Mondeo (2.0 GLX).

If you do it in a smart it feels like you could reach out the window and rip
the Volvo badge off the truck behind you - most disconcerting.
Wonder how much I'd get to trade my volvo for a smart - that'll reduce my
costs...

Some cars have a dreaded 'boom' resonance around 70-80 mph, that makes people
drive them at 80-90mph at motorways. Probably not so much these days than in
past years.

But this might not help 0-60 time if the engine is peaky and need to be in
the power band to produce the goods. Close ratios means that the power band
can be better utilised.
However, 0-60 is as a performance measure is not ideal. In fact it is
theoretically possible that a slower 0-60 car will cross the finishing line
of a fixed length track before a faster 0-60 car. (even at full blast!). IMO
we should try to get away from 0-60 time, bet it will never happen.

Our aftermarket exhaust is noisy in the 68 - 71 indicated zone, at 72 or
higher (indicated) it's quieter. 72 indicated is ~67 GPS reported, so that
works.

Yes it does, but the difference for most cars is changing from second to
third or not. On a few, there could be a third to fourth. Using taller
gearing can improve acceleration because the engine spends more time closer
to maximum power.
As you say, this is a "problem" with using one benchmark for performance
measurement. Shorter gearing makes it easier to keep the engine on the boil
over a range of speeds but off the line stuff, it's not so useful.
If our Ka had slightly taller gearing it would probably be marginally
quicker over the quarter mile. I'm approaching the quarter mile point above
maximum power engine speed in third. Peak power arrives at 5,600 rpm and
drops off very quickly; we cross the line just under 6,000 rpm in third
almost at the limiter. It's not worth changing up... :-/

We already have, almost all manufacturers use 0 - 62 these days. :)

Re: Change final drive ratio...
Personally, I'm much more concerned about 40-80 times than 0-60, since
that's what you want when accelerating onto a motorway; I very seldom
need to floor the accelerator when starting from rest anyway.

Yes, and it's very unhealthy for the car anyway: Burning clutch, gearbox
grind, CVJ wear, squealing tyres. Save your car and let the others do it.

It's not what I want, but I know what you mean, heh.

Not if you accelerate with mechanical sympathy of course.

Just my two pennorth. If you changed the diff to get around 2-3k revs at 90
instead of 4-5k you'd be roughly halving the gear ratio (doubling it? I
dunno) in all gears. This would make 1st equivalent to at least 2nd and
would mean slipping your clutch even more when starting.

I've read that 0-60 testers perform certain tricks, like moving the left
foot sideways off the clutch.

Erm, but that's not the same as applying full throttle from rest...

They do that too. I guess that they must wear slippery shoes such that
they can easily slide off the clutch pedal rather than lifting the foot.

Anything with a noticeable power band will probably accelerate quicker if
you don't dump the clutch.
