WTH are "500 HP rods"?
There are far too many unknown parts to your question- the exact set-up needs to be laid out.
Anyway, 5 psi will be too much if the tune is off, 10+ psi could be conceivably done if things were exactly spot-on.
IMO, if you are serious about running boost- use the right parts from the beginning. That way there's a bit of a safety margin when (not IF) things go wrong.
