also have to consider combustion chamber shape,camshaft profile,fuel metering system,ignition system controller,,, look up the new mazda economy engine that burns gasoline and has 14:1 compression.lots of high tech euro engines have 12:1 cr.,,,cooling system makes a difference,metal used in cylinder head,like aluminum or cast iron
