Could someone chart octane and with steel heads what compression ratio would be within the range of that octane.As a example:

87 octane pump gas and you could run up to a certain compression ratio

89 octane pump gas and you could run up to a certain compression ratio

91 octane pump gas and you could run up to a certain compression ratio

91 octane pump gas with additive and you could run up to a certain compression ratio.


Thanks
