Heres proof right here. BMW's own I6 production manager, the head guy in BMW's I6 powerplants saying exactly what I said about the weaker Mg/Al N52 block. And I quote Mr. Welter,"

In the case of the magnesium-aluminum block, Welter says, “Right now, the crankcase-stress of the turbocharged engine is above the limit of the aluminum/magnesium crankcase.”
Okay so we have someone 'saying' it rather than providing actual proof of trashed engine - if mmw's car gets trashed, at least we'll have proof.. And if it doesn't? What the hell was bmw talking about?

Unless sc puts dfferent pressure on the engine than turbo ?
