Im sure you can run 10 psi for a long time, you also have to realize how often are you really running at 10 psi. Not very much unless you are racing.

most of your driving with be in vacuum or 1-3 psi

You can be at 10 or 12 psi for less than one second and pop the motor... there are just too many variables that contribute to a motor living or dying under boost that can each be discussed in any meaningful detail when someone is asking "Max boost?". **** happens... people need to be aware of it. In the meantime its beginning to cool off... and I am waiting for that extra 1 - 1.5 psi to come back
