Here is Gulfm3's half shafts. Don't think it's the diff these days. We went to RPR last night and first launch of the day.....

1000hp axles here he comes!

lol he has only been running 500+ hp on that car for several years, and a lot of launches at the strip on DR's. What are you running?

He didn't actually drop the clutch that much, just didn't feather it as much as he normally does.

If you get stronger axles, the next weakest link will fail.
Personally, considering how much easier axles are to replace, I'd rather them be the fuse than the diff.

I have yet to blow a rear end, but I did break an axle like that on the street..I wasnt even launching, just getting on it in 2nd gear. It didn't even wheel hop.

I realize that, as does my brother. It's debatable on whether the new revised diff (06 and newer) is that weak.....

Interesting . . with the axles.

I believe that because the V1's Diff is suspended from the top,
at 3 unequal and 2 far off centerline supports, is what contributes to its case failure.

The two rear supports, especially the right rear support is very far off 'centerline'.
During hard acceleration, the occillations and torque twist puts a hugh stress on these supports.
The further the distance from centerline the support is, the more movement is created.
The smooth right side of the case with less webbing to dampen vibrations, occillations, harmonics,
and the stress put on the 'way off centerline' right rear support during hard acceleration & torque twist causes case failure.

I'm currently working on a way to have a 4th support.
I should be done within a week or so,
but I baby my car which makes me a poor test pilot.
Maybe a sneak peek in a week.

Might as well share mine.

you can see the difference between the way my Hendrix sheered off compared to the stock ones. (mine was a flaw in the tempering process)

Wow!

Very few shiny dots.

You obviously got the 'tootsie-roll twist' heat-treatment.
