I think 6-8 lbs of boost is ok without forged internals, the compression ratio also has something to do with this, the lower the compression the more boost you can run, usually 8-8.5:1 is a good starting point, more boost and you have to run meth injection to stop detonation. There is a lot to do with timing and Air fuel ratio. And also the intake air temp or IAT. That's why most forced induction units run an inter-cooler.
