        if I have a 9:1 compression ratio engine should i expect an
        combustion chamber pressure of 9 x ambient pressure.  i don't
        think so as 9 x 14 = 126 psi.  i measure (to specs) 180 psi!

        what am i missing here?

Temperature increase due to the compression, which affects the pressure.
