    M20 e85 cr?

    I'm thinking about going E85 (104oct) on my m20b25 build, so i can pass emissions (lol) and run a higher cr. + The price of regular pump gas is rising and rising.
    I will make new suitable fuel system anyway so dont worry about that.

    What would be a good cr for an N/A engine. With a schrick 284/272 or maybe a more agressive cam.
    12? 12.5?11.5? ...

    Sorry about all these questions, i have tried to find some info on this myself but i have not found anything of value.

    I'd say 12.5-13.5, but I think it'll depend on several factors
