Boost guage calibration

My former corpse '83 244ti is ready for more boost. It's up to all 'stage 0' standards, and begging for more. I just finished installing the intercooler today, and it works great. I figure with the intercooler plus my straightpipe, I can run around 11psi with 93 octane without problems. Does this sound reasonable?

Anyways, tomorrow I plan on calibrating the stock guage with a pressure guage I'll tee into a line. I'm going to just mark it off throughout the yellow and red zones, one mark per PSI. Just to be sure it's accurate though, I'd like to know what the stock black-yellow-red guage is actually displaying. I'm thinking in terms of a clock. At stock boost, my guage goes a little past 12, or halfway into the yellow. This should be 5.5-6psi to my knowledge. What is the actual boost at 1, 2, 3, 4, 5 o'clock? thanks for the help guys. Hopefully if I can get the right figures I'll avoid broken rods and sending my project back to the graveyard.
