Since when is 11:1 compression considered "mild"? Most production engines have compression ratios below 10.
Maybe 15 years ago
With modern combustion chamber designs that maximize quench and injectors that atomize well, etc. 12+:1 CR is easily obtained on pump gas.
Just look at these cars running on 87 octane.
Put some 12.5:1 pistons in these engines and Id think youd have a real case for E85 actually showing worthwile gains
