Understanding & Measuring Compression Ratio (2T & 4T)

[90GTVert]

Compression ratios, including static / uncorrected, dynamic / corrected, and effective / boost, are explained. Then details are given about measuring and calculating compression ratios for two-stroke and four-stroke engines. There's an index just after the intro to make it easy to jump to something if you need it and a quick reference of formulas with a little unit conversion info at the very end.
