Properly built, the M113 engine should be able to take up to 3 bar. This is equivalent to 1400hp.
Of course, this means wet sleeves, 8:1 compression pistons, new forged rods, dry sump oil pump, 1500cc, larger oil squirters, upgraded head studs, 3-layer MLS head gaskets, etc.
So the motor will last 5-6 full power runs before a complete rebuild is necessary, but you did ask.
