Killed my drive shaft on dyno

1st run was 421hp and 745 torque. I think it should have been ALOT more. I couldn't keep the tranny where I wanted in 4th but Adam Cornell said I had alot more in her. Well this was my second run which was the demise of my drive shaft.

Was it out of balance or something? Where did it break?

You should have more then that, tuned 6.0's can do that.

The front half was twisted and I had it straightened and the whole shaft balanced.


You can see where the clip sits in the yoke and you can see where there is a small amount of the yoke missing which allowed the clip to pop out and just went from there.

And all this did was knock my flex pipe off my elbow for the stack and it broke the rear yoke.
Plus i was at 3900rpm when all this happened.
