Some facts for you
Guys for what its worth all (I'll repeat it again ALL)the cranks for all nova based engines come of the same CNC lathes and are batched through the same heat treat process. whether you get a good one or a bad one is luck of the draw just like getting a good or bad sleeve set. These all come off the same machines also. Cranks have been prone to breakage in all the novas 12 varieties from time to time since the first rear exhaust engine appeared. It is not a chronic issue but I have seen all of them break a few cranks either through the window or at the root of the big bearing. It just happens. More power pushes the engine to the limit of material fatigue simple as that.

The new NS, the Novamax and the RB V12 will carry the 11.5 MM crank. again common crank, case and bearings. Just a badge change.
