Big Stroker Build, school me on the Audi AWD system and tell me if its the best fit

I think the Haldex differential might fit the bill but I need to know ratio's, what the front to rear bias is, what years and models the rear diff comes from, electronic control, any aftermarket upgrades they offer on the Haldex.

I'm not hell bent on using an Audi system, if you all can think of something else i'm open to all suggestions.

System must support 650 ft lb @ 2000 engine rpm and up to 750 hp.

What car are you building?

Its an old Jeep CJ we figured it out though, it was a lot easier to go with a Dana axle.

If it's a Jeep you'd want the Torsen diff.
