That depends on a lot of things, I recomend this book "Maximum Boost" by Corky Bell, it helped answer a lot of questions i had about turbocharging.

Well 2x .68 ar ratio and a Crane Cam 228/228 @ .050" .512/.512" lift. about 600+ hp to 900

im running 700 rwhp on a 331 with a ported cobra and used heads.(my back up motor dont ask)

boost depends on tubing size and turbo compressor volume.

airflow is different than boost. boost is a restriction reading.

i run 2 blow off valve's and two waste gates to allow boost to build quicker and limit boost for the street.

seriously though a .48 a/r would do it and sneak up on it. fuel and intercooler play a part also. you can get crazy horse power with that combo if you turn up the boost .

When i did my first build i was given the Corky Bell book and its great.
