This is actually a 4 cylinder Mitsubishi application and I forgot to mention that it is making about 600whp. The pistons and connecting rods were upgraded forged units as well.
The rod is actually bent into a "U" shape. As you can see the wristpin is still intact and the connecting rod has been folded into this orientation within the crankshaft counterweight.
This is an AWD automotive application and the failure occurred while drag racing during the initial launch / first gear acceleration. I'm basically trying to gather input on whether the piston or the connecting rod was the cause of the failure, or if it is likely that the engine was over...
Unfortunately the piston has disintegrated so we are unable to use that to form an opinion on this failure. Please let me know your thoughts, thank you!
