This interesting.
I now run a Detroit True Trac in my race car it gives great traction on hard take offs and the car stays straight, whilst they are a similar design to a Torsen they are much stronger as I found out. Torsen diffs are not recommended for Drag Racing as the gear housing is cast iron photo shows results when they go bang. And with me mainly do hill climbs that is like drag racing up a hill.
I recently asked Steve Saleen what is a "Max Grip" differential is it just a beefed up Ford LSD or a propriety brand......his answer was it is stronger, no real answer to my question.
When I accelerate heavy on my S302E it pulls hard to one side and no way I can keep it straight. I have bought another Detroit True Trac for it, so it will be interesting when I get to take back cover off it to see what was actually fitted.
I believe the PJ's just had the standard Ford LSD with 3.73 gears
