compression ratio for boost.

i ahve a question for the big tuners out there. what compression ration should i look at to nicely spool a focus power turbo kit on pump gas to make roughly 300 whp.

i know i need forged rods and pistons and that tio keep it from exploding i have to drop the compression slightly (or so ive heard.)
