I already posted something in the motorsports section of the forums, but figured that not everyone would see the photos...
Anyway, here is the background. I was at the dragstrip, did a good burnout to heat the tires, brought my rpm's up to around 3000, hit the nitrous, held the brakes until the lights came down, and launched at roughly 5500 rpm's at 20+ lbs of boost and the 100 shot on top and blammo!! These are a few photos of what happened...

That was definately the hardest I have ever tried launching the car. Here is my setup for those that are unfamiliar, I run a solid diff mount (from MSA) in the front and urethane bushings on the mustache bar. I have a 3.36 R200 LSD, Z31 300zx turbo CV"s, and Ross' CV adapters on stock 280z stub axles. As far as I can tell, the front diff mount pulled up through the front support bar... shown here

.. then broke the rear cover from the diff (bolts were still attached to the mustache bar), the diff torqued to the right, destroying the driver's side CV. OK, there appears to be no damage to the differential itself (just the cover), no damage to the passenger's side CV, and the mustache bar is not broken either. The driveshaft required a new u-joint... no biggee. I know it could have been much worse.
I never even considered that the front support would fail like it did, so I figured I'd better put this over in the drivetrain section, just in case the info is of use to others instead of having it buried in a Motorsports thread about Orlando.
I intend to reinstall the R200 for the time being, reinforce another front support prior to installation, while I decide on my next course of action for the rear end.
