Read the latest issue of Car Craft with 2 badass musclecars with twin turbos putting over 1000 horses to the ground with E85 fuel. I remember reading about the new Green carbs from BG and I think Holley may have one. Seems like the only mods you have to make adjustment for is for more fuel since E85 requires a more rich mixture than good old standard gas. I was wondering if any of you guys have played around with the new corn juice and maybe had some benefits. I'm all for the US to be self-reliant when it comes to oil/gas.
How hard would the conversion be from a standard EFI motor to the new E85 motor and what would be the mods?
