12 seems to be the suggested maximum. I don't know about cracking them in half. I'd think your headgaskets would let go before that happens.
Maximum safe boost pressure for a 6.9
What is the max safe boost pressure for a 6.9? I have a Hypermax nonwastegate on mine.
A friend of mine cracked a 6.9 in two when he was running 15psi.
I know that a 6.9 really wasnt meant for boost, but I would like to know what kind of boost limit I should be watching out for when I slap a boost gauge on this mill.
