Good question, I have forged pistons and conrods in my H6 which was done as future proofing as I wanted to increase the boost with my sc setup have still yet to see more than 7psi despite running a pulley capable of producing 11psi. Currently going through a long and tedious process of trying to detect any leaks.
I would happily run higher boost/flow until we find the next weakest link which would probably be head bolts. If the engine was standard I don't think I would like it if was making more than 400hp having seen how easily the conrods bend.
The first engine died after eating to much CAT
The second engine died of a broken piston
The third engine is in the car
The fourth engine is in the machine shop
