expansion of fuel/air mixture

[Camden Lindsay]

I was (probably inaccuratley) trying to figure in-cylinder pressure at full 
throttle bottom dead center (beginning of exhaust stroke), thinking about 
how cams are designed in terms of open/close ramp, time and such.  Is there 
any fairly accurate way to approximate this, depending on engine swept 
volume, compression ratio, volumetric efficiency and fuel ratio?
thanks again
