i know Subaru AWD in normal condition torque distribution 50/50
but in specific condition how much maximum of torque can send to one wheel ?

see XWD can send 85% of torque to one wheel

 

The non-DCCD setup does indeed run a steady state 50/50 split. It'll depend on whether the centre and rear viscous couplings' silicone oil sheers enough to be able to 100% fully go solid i.e. lock input shafts to output shafts. . If so, then theoretically 100% can be sent to either front or rear, and also to either side to one wheel.

The front diff is free/open so that will defo do it to one wheel - i.e. in the case of a free diff, the wheel with 0% grip lol - assuming that 100% can go forwards (and rearwards) that is.

 

ok
Under normal conditions the car will send power like this:
Front Left - 25%
Front Right - 25%
Rear Left - 25%
Rear Right - 25%

but in specific condition in front right wheel is slip
how is torque distribution on all wheels?
Front Left -? %
Front Right ? %
Rear Left -? %
Rear Right - ? %

but in specific condition in rear lift wheel is slip
how is torque distribution on all wheels?
Front Left -? %
Front Right ? %
Rear Left -? %
Rear Right - ? %

 

Theoretically...

but in specific condition in front right wheel is slip
how is torque distribution on all wheels?
Front Left - 0 %
Front Right - 0 %
Rear Left - 50%
Rear Right - 50 %

but in specific condition in rear lift wheel is slip
how is torque distribution on all wheels?
Front Left - 50 %
Front Right 50 %
Rear Left - 0 %
Rear Right - 0 %

...As said, assuming the VC CAN send all torque rearwards or forwards. The above examples assumes that one axle's pair of wheels have lost all grip, and the other axle's wheels have the same amount of grip each.
