Most of these type of failures are from people running the engine speed to high with a stock oiling system. Its hard to expect the stock oilpan volume to keep a 7000 rpm engine alive when it is accelerating as fast as these cars do, it is worse with a transbrake launch. You can run restricted pushrods and a larger volume pan like the Moroso and get by in the high 8's, but any faster and a dry sump should be on your shopping list.

Total car newb here, but here's my theory:
Sounds like it simply ran out of oil too fast, before the oil could return back to the pan. With a higher flow pump, oil is pumped out of the pan faster than a stock pump and if the time it takes for a pump to empty a pan of oil is shorter than it takes for oil to return, there will be oil starvation dry sump or not. It's just that usually dry sump systems hold more oil than wet sumps so it's not likely to happen.
Simply upgrading to a larger pan should solve the problem.
I have little idea how the whole system works; but judging from the pictures, a large pan that feeds oil to the front of the engine but draws from the back should theoretically perform almost as well as a dry sump system. This way, even under high G's the oil is sent to the back where the pump draws it and is then sent to the front of the engine where it is then quickly distributed throughout the entire engine from the g force.
Feel free to ridicule me if I've said anything stupid. It's the only way I'll learn.
