Compression Ratio using 91 octane fuel Hello everyone, could someone tell me what is the maximum ideal compression ration using pump gas 91 octane fuel. My car will be used as a street/strip car but not a daily driver though. Thanks in advance for any information giving.

12:1 can be achieved on pump with a very good tune and the right selection of parts. however dynamic compression is much more important than the static compression number to determine whats safe on pump. to figure out your dynamic ratio we'd need to know your cam choice as well as stroke bore etc.
