## Main Question or Discussion Point

What I am getting at is I would like to find out the psi of some engines.

Is there a formula(s) to get good estimates or exactness of the pressure made in a cylinder.

For example, you would need the cubic inch, static compression, cam specs, etc...and at a given position of the piston get a pressure number?

I hope that made sense, thanks for any help or suggestions.
