[QUOTE="AD_EG, post: 3942903, member: 74396"] honestly bro i am not very sure... but what i am sure of, compression ratio is not determined by what engine you have necessarily,it also depends on how much your fuel octane level can handle... normally for compression more than 13++ you need a higher level of octane to be safe...when your compression is too high,and the heat and pressure generated in the cylinder can pre-ignite the fuel even before the spark is shot in...which leads to pre-ignition or also known as detonation. you can up your compression as much as possible but many things need to be taken under consideration if you are going for high compression(my definition of high is 13++)....such as cams,your engine breathing,air flow,fuel octane(ron), good tuning for air+fuel mix... and normally for cars which are turbocharged,they have lower compression ratio's to be able to boost higher safely...
