It'* funny, but at Woodburn for WCBF04, all 4 of my burnouts were two wheels. Without an LSD. In fact, all four cars there had mostly 2 wheel burnouts that day.

The danger for me with the siping on the tires is that the tires will break loose like they did, but they grab sooner and more abruptly than non-siped tires. So when it finally gets traction, it hammers the diff.

I would suspect that sudden traction at high revs would be hardest on the input shaft and not the diff (at least in a straight line).

You da man, Todd. But on the other side. I shattered an output shaft, and broke the housing.

Is it possible the dif failed and took out the shaft itself as well as the housing? I don't think I've ever heard of anyone "snapping" an output shaft but it could have been obliterated by a failed dif for sure. It gets pretty violent when a dif fails.

Pardon me.....the shaft between the CV and diff. CV shaft in the housing.

Diff is fine, at least on one side The car was still driveable, but only the left wheel had power.

hehe, I still have that tranny sitting in my garage on my engine hoist. It will be used for "learning how it works" pretty soon. Then it will be scrapped!
