A stoichiometric burn of E85 needs about 67% more fuel volume as gasoline, and could achieve around 17% more power with that extra fuel flow. It is not very energy dense.
Though knock is definitely the immediate limiting factor here, not fuel flow, I just wanted to put some numbers to the "E85 needs way more fuel capacity" story.
