I think it's tire dependent, because I did a 3K dump on my csvt with an open diff on my 215/45 KDW and I had wheel hop like mad. . .I rotated tires shortly after that(I was had driven 7k on those front two w/o it, BAD SUNEIL), did the same full dump at 3k, tires squeeled with the open diff and I was just flying. . .I need to make it to a track, though, to figure the logistics out. . .now with the quaife, I'm thinking fun time. . .
