OMW has ds650 bored and stroked with nitrous around 150-160hp on nitrous.

How many passes does he get on a set of 160 hp 250R cases?

There is a local shop that builds a lot of turbo engines.  He has brought me 2 sets of cases from his 125 hp 450 Hondas and and 3 sets of cases from his turbo 150+ hp Raptors wanting to know if I can save or strengthen them.   All of the cases are split through the main bearing and transmission bearing pockets after about 10 passes.
