Default DCR in a boosted motor

I'm trying to see what my DCR would be at various boost levels.

Specs are:
4.03 bore
3.875 stroke
6.2 rod
52.5 IVC
SCR 9.4:1

I'm getting a DCR, NA of 8.16. With that much compression, I'm wanting to see what kind of boost I can possibly get away with on pump gas.

If I'm totally off the map, please elaborate.

you must know valve / camshaft events to determine DCR.
