EU differential - Clutch or Torsen?

[MLO 351]

This explains why my UK manual Mach1 takes an age to get moving then, i really can't see it getting anywhere near 5s to 60mph. Having done 1400 miles now, driving normally (i.e. not a planned standing start at higher rpm) setting off and mashing the throttle provides very sedate progress until 4.5k lands. Same when pulling into a road in 2nd at say 20mph, very little push is offered which is the only real disappointment i have with the car.

Why the feck have the export models been hampered in this way??

You will need rear gears to wake it up, that's one of the reasons I went 10 speed.
Not only do they get better gears in the US but the handling package Mach 1 also has just over an inch lower diameter wheels that helps with overall rear gearing.

That is why you go A10

Tried the A10 last time, although a great box and quicker it just doesn't have the feel of driving the manual, nor the tone (never been a fan of that stupid slurring noise autos make when they shift vs manual)

This is interesting. According to the German specs, the Mach 1 should get to 100 kmh in 4,4 s (A10) or 4,8 s (M6). 100 kmh is ~62 mph, so the times for 60 mph (if the UK specs are the same as German ones) should not be worse. Unless there is something else going on (e.g. related to RHD).

You need to keep it above 4000rpm for the engine to wake up properly. The gearing is long, even though not as long as in the GT (Tremec helps a bit)

It is "not" a car quick of the line, its a big na engine and high reving. But the beans are there you just need to keep it matched for maximum power/torque/gear and it pulls hard!

You can get the Torsen-diff itself for around 900EUR from Germany the 3:73 gearing is another 400 or so EUR

Can you share links for that ? Wavetrac is 1100 EUR so it's not a big difference and Wavetrac is supposed to be better. Ether way please share links.

Yes, i know this and it does come alive above 4k rpm. My point is that the majority of starts in the real world aren't like this and in normal operation it's very slow to respond. Sadly not exactly practical to do 4k starts every time you stop at a junction, roundabout etc!

I just feel it's a tad disappointing and pedestrian off the line or at low speed when burying the throttle, with very little 'shove' in the back compared to the vast majority of vehicles i've ever driven in 25yrs of driving! Just a quirk of the vehicle and gearing, i guess i need to live with.

I'm sure this is possible with multiple attempts and clutch abuse, but doesn't reflect how it's driven in the real world i.e. starting from low rpm and hitting the throttle vs high rpm and clutch dump start.

When I got my GT I had the exact same feeling (waiting for my Mach 1 to arrive....)
The Mustang is so easy to drive, you can lend it to your grandmother anyday - she will not bother to exceed 4000rpm anyways.

Putting it into sport + or track mode changes things quite a bit, and it does get more responsive.
As I am not into 0-xxx times it does not bother me any longer, I now know when and where to use the best of its setup to get the most out of the engine.

Doing a 0-100km/h and when you change into 2nd gear and you see the speedometer at about 90km/h and getting wheelspin then you feel the brute force of it. But first gear is not often used more than in town so 2nd 3rd are the most fun gears and 4th if you are stretching the speed limits just a tad....

I can agree that the gearing is too long , then again without this gearing I would say that we would not have received the Mustang V8 to Europe at all due to emissions. The A10 has never been an option for me - I have an automatic in my daily driver car and want to be rowing gears as it should be done.

I would have also wanted the 3:73 + the Torsen as in the US

The diff seems to have increased in price since 2-3 months ago

Its not a cheap mod ...

I paid £1292 including shipping (€1500) for the Torsen, 4.09 gears and the install kit (everything is Ford Performance) from another member who sold his car - but everything is unused, new and boxed.

You also have to factor in the cost of installation and for the later model years, the additional cost of a tune.

Should be a big step up from a euro 3.55 car though - I cant find it now but I am sure I read on here that someone had done the calcs and it was a equivalent bump to adding 40lbft to the flywheel (and that might have even been for the US guys jumping from a 3.73).

Is it not possible to change the gearing in forscan at least to 3:73? Maybe not on the 2021 models though

 

[WD Pro]

I don't think so - from what I read I think things got difficult with the arrival of the rev matching feature

Apparently it needs a tune for '19 and up.

Aside from this difference in gearing, is there other difference than durability? For automatic we also don't get Torsen 3.55 in Europe but Ford's trac-lok 3.55 but seems to me that in case of automatic it's not such a big problem?
