Hi everyone,
Those of you who have built up a Type IV 2.0 with higher compression, what is the safest compression ratio to use 93 octane pump gas? |

Yup, unless you are really significantly changing the design of the combustion chamber and adding lots of sophisticated sensors, the cam has the single largest effect on what compression ratio is appropriate.
