    you can run 11 psi before you need a 3-bar map sensor... the 450s should be enought to take you there. it all depends on the tune. psi should never be a goal. power breaks parts, not psi numbers. stay under 275whp and you'll be ok.

    did you not read his post? he said stay under 275whp and you should be fine. provided that the engine hasnt been beat to hell.

    agreed ^^^^

    You may be able to get that power without having to crank up the boost level.
    If anything i would worry about reinforcing the block just a tag. ARP rod bolts and i assume you already beefed up the oil and water pumps right?
