E-85 Racers in California

E-85 advantages are with higher compression builds. You will need to change metering blocks in carb(s) (or fuel map with EFI) to accommodate the higher fuel to air ratios. E-85 summer blend is about equivalent to 100 octane fuel.

Expect to get 30% to even as high as 50% less fuel economy. But at 300-400% less in cost compared to race gas? It's a bargain. I am running 1/2 fuel lines to fuel cell for strip/street build. So volume worries non existent.

I don't see much advantage for daily driver use.
