But there will always be a point where no matter how much you do to an engine, you can use too large of a F/I mechanism. This is where A/R ratios come into effect, but you know that already. Plus the question was how much a stock EG33 can handle, not about where peak boost is made.

Thats the point of boosting an engine. To make peak torque and HP in all the right places. What I have done thus far effectively has pushed the limit of the stock engine in all the right places and none in the wrong. I can use the 9psi throughout the entire rev range safely. So it still stands that the engine can safely handle 9psi w/o an intercooler and maybe a little more w/ one. This is something I should be toying with soon. But that still does not solve the flow issue. Up until about 6krpm you can run up to 9psi hot. That is a fact that I have been able to uncover thus far.
