do not run ethanol on stock injectors, that should be a given. It takes about 30% more fuel to run E85. I got 860cc injectors for my EvoIII 16g so when E85 becomes available, i can run it. 860cc is huge for an evoIII16g on gasoline, but pretty much right where it needs to be for E85.

that's just because of difference in stoich between the different fuel types...ethanol requires more fuel, just like every other alcohol fuel

yeah, dave and I've been PM'ing each other for a long time on that...I helped him with some fuel info from an MIT project.

we often discuss each other's builds, manifolds and cylinder heads
