EVO 8 DIFF fitted & working

[bradc]

judging from above I would say it works like S-AYC, considering how completely different the internal diff is designed.

Hi, YES the mechanics make it work. the AYC system is identical to ours that is why it can be swapped. Our ayc ecu controls the pump and valves exactly the same.
THE ONLY DIFFERENCE IN POWER TO THE DIFF BETWEEN A LATE MODEL EVO AND ONE OF THOSE DIFFS FITTED TO OUR CARS IS THE ACD (ACTIVE CENTRE DIFF). THE ACD IS LIKE AYC ONLY IN THE CENTRE OF THE CAR ALLOWING MORE POWER TO FRONT DIFF OR REAR DIFF (IT ONLY DOES THIS MOMENTARILY) THE SWITCH ON THE DASH IN AN EVO HAS THREE SETTINGS TARMAC, GRAVE,, SNOW.
tHIS DOES NOT MEAN 3 DIFFERENT SETTINGS LIKE 60:40, 50:50, OR 70:30.
THE SETTINGS ARE FOR THE LENGHT OF TIME THE CENTRE DIFF ACTIVATES AND STAYS ACTICE. sO THE CENTRE DIFF ON THE EVO CAN PASS MORE POWER TO THE REAR IN SOME CIRCUMSTANCES.
(SORRY FOR SHOUTING, i HIT THE CAPS LOCK AGES AGO BY MISTAKE! )

I'v enever seen a car with GRAVE setting before. Is this the suicidal drift style setting?? (sorry, couldn't resist!!) lol

[Louis]

Oh t*ts, speed typing is not my thang! , and yes, the grave setting would not be that popular! lol, cheers

Sounds excellent - look forward to hearing more member accounts of this swap.

both of course

[Gly]

how is this going?? still strong?? how many miles? km's? have you covered since the swap now?

[bradc]

the diff will be fine, I'm more concerned about the transfer box life because the gear ratios are different from vr-4/evo4 to evo5-9

[Wodjno]

I wouldn't be concerened at all about the transfer box ! the ratio difference is that small, that 2mm tread difference(front to rear) on your tyres would be a lager ratio ...
Have u ever read about the diff ratio's on Landover Freelanders ? Quite interesting and amazing what manufacturers will do to make a vehicle have better handlling !!!!!!!

[bradc]

it is small, but there is still a difference

[Wodjno]

it is small, but there is still a difference

As there is with peoples tyres

[Gly]

anyone else running S-AYC?? comments?? concerns???

[bradc]

ok, I did the sums, the rear wheels would be wanting to go 5 revolutions per minute faster at 3000rpm in 5th gear, which is over about 2km travelled, or to put it another way, the rear wheels will have wanted to travel 10 metres more in 2km.

Dunno what the tolerances are to be honest!

[Mark 4]

Fitting mine next weekend.

[Wodjno]

And if you were running 225/40 18's and there was a 2mm difference between front and rear tyre's !

Then it would be 7.5 revolutions per 2km ! Or approx 15m's !

So i take it you haven't read about the Freelander then
