M120 Compression Ratio Detuned Model CR
Hi
İm build M120 right now for swapping c204 i calculate the cr and im get shock i know my engine detuned version from w140 S600L and normaly should have 10.1 Compression Ratio but mine have 9.1 CR .i measure the combustion chamber volume 10 time and result 56cc . İ think mercedes increase the combustion chamber volume and add more timing to run engine leaner safely for efficience and lose some hp .i dont know if im wrong or correct some where if some one know the answer i get happy .
there the combustion chamber volume measuring
