PSI through xturbo=yHP

[JJ240]

Is there a way to determine how much PSI of boost it will take to acheive a certain HP goal with a certain turbo using the flow map? Theres alot more involved than just the boost and the turbo I know, but is there a way to estimate? Im planning to do the SR swap soon and Im hoping for around 325-350HP eventually with the HKS GT2540 internally wastegated. The turbo is good for the 350HP range Ive read, but this doesnt tell me what kind of boost I would be running to hit that. Im trying to plan everything out ahead of time. I figure Ill be running 440cc injectors or so with a JWT ecu and SAFC for tweaking if need be.

I think it has a lot to do with charge temp and turbo efficiency.. no real "equation" you can use to determine hp.
