I am ordering new pistons for my Teksid build and am pondering running E-85 in it. It is a stroker motor and has an F-1c feeding it. I was running 20 psi on my old motor on pump nand meth with a 9.2:1 cr. Does anyone have a reccomendation for a CR on E-85? I was thinking in the 10;1 range to give the motor more response and power off boost.
