Boost vs. Compression Ratio
I initially made this forum a few weeks ago so we can each contribute some nice and easy charts and formulas so it's easier for us to figure our cars out. Here is a very good one that I picked up in the past. I wish I could credit someone but it's been a while since I initially got it.
It gives a GREAT reference to how high your compression may get while using a said amount of boost. This can be helpful for many reasons, including what gas to run at said boost level.
