agree with hyperex on both counts.

Dont know the standard centre is rated to high power, and there is no reason why you would want to put it in.

Is a bit of a gimmick.

I pretty much never touch mine. leave it fully back.

Although having spoken to anders, may resort to two notches forward in heavy rain.

Am waiting till quaife produce a centre diff.

Apparently atbs are not necessary, just a torsen viscous coupling. Would need to speak to sdb on the merits of these before making any decisions!

 

Can someone educate me on how it operates electrics wise? Does it use the cars computer for anything, or is it self sufficient? The main question is, can it be fitted to a car that was not originally fitted with it. Is it possible?

Greg

 

Sure its possible... but not cheap. Suggest you use a mechanical centre diff.

Hyper

 

I would consider front LSD rather then center diff if i were you.

Section 8,

The adjustable centre diff is incompatible with the subaru ABS system... you can have one or the other.// if you have ABS it will not work correctly if you fit the adjustable centre diff.
You can uprate the centre diff using the 12kg(iirc) STI unit. This should make a noticable difference to the traction available, but I would fit a front LSD unit before uprating the centre one.

Adam,

There is no such thing as a Torsen Viscous differential. Viscous couplings (using sheer forces on a viscous substance) act on speed differentials, TorSen differentials are mechanical devices that use the "one way" properties of helical (worm) gears to provide progressive locking based on torque differentials (TORque SENsing).

Moray

 

sorry moray, I missed out the word or.

But I take your points.

Did you know that ford invented the viscous coupled centre diff, and coined the phrase too!

 

Thank you all.

I didn't plan on fiddling with it much either. I just would like to have some rear torque bias.

Does the Type RA center diff not like to make tight turns on tarmac? I have been told that it has a rear bias, but wouldn't be good for a street driven car.

Do any of you know of any rear bias center diffs I could investigate? I know of the Cusco tarmac diff, but it isn't something for the street either.

Does a little rear bias have any advantage over a 50/50 split? Or is it mostly just a "feel" sort of thing? Is it something that is not noticed unless you have a large power upgrade?

Lastly, with the limited knowledge of torque sensing diffs, it would be a more or less "automatic" torque biasing center diff, and gives rear bias when you need it. Correct?

Thank you,

Greg
