Hi Dr. T,
I am driving offroad at the track in Bergedorf, but I have heard that there is an on-road track in HH-Boberg (never have been there).
I used to have a Torsen in my former Truggys and buggys (brushless), it just works like a real 1:1 Torsen. There are differend LSD-Limited Slip Diffs around, the Losi SD, the XRAY Active Diff, the Kyosho diff, Torsen, the BBF's, Fioroni etd. The one I have is a Hobao/ofna Torsen for hyper 7. about 10yrs ago they have been popular, and where available for Hobao Hyper Cars for example.
AFAIK Walter Röhrls Audi Quattro had Torsen Differentials:

I used it in center, it kind of locks the diff, most of the power gets to the rear when I pull the trigger. I loved it. But you have to get used to it, the rear might get nervous, an you don't have a "pulling" front wheel. Locking can be very sudden.
I have this one, found mine on egay usa years ago:

I am now running a Losi Smart Diff in Center, the Torsen doesn't fit in my current truggy. It has a less locking function then the torsen unfortunately, but in total better then a normal Diff with 60k fluid. Locks less then the regular 60k diff, but corners very well.
The Losi SD require more maintenance then the torsen. I used the Torsen in two cars, the worm gears are like new, one outdrive has shows some wear.
As you can read, I am really a big fan of torsen
How long is your center diff in total?
I will check out that fishing line trick!
best regards
