You also need to consider the volume of the cylinder. A larger volume (low compression) packed with the same pressure as a smaller volume, will make more power.
exactly!!! the person who just "has" to raise the boost levels and blows his engine just because he thinks 8lbs is a "small number" is an idiot who probably shouldn't be making decisions about his own car. unless he just doesn't care about money of course.As long as the cylinder pressures are the same, you'll make the same power.
How so, air pressure is air pressure, no matter how it's pumped in.

Not exactly, you can have a lower peak cylinder pressure and still make more power.
But I will play along, so are you saying a motor with 11.0 compression ratio will 8 lbs with make the same power as the same motor with 9.0 compression and 17 lbs? You need to give some real world examples.
Also about why high compression helps with a turbo. High compression will help spool the turbo faster. It wont make nearly a big difference on a supercharged car.

Not sure how the numbers you provided would play out, as we are lacking a lot of key information to come to a conclusion. For one, we don't even know if the numbers are even in the right ratios. Also, maybe the 11:1 motor could handle 12# and the 9:1 only 15#. Too many details are missing and I frankly don't want to do the math right now.
As for the turbos, I wasn't talking about spooling. Boost pressure is boost pressure.
