Why? you need to run it richer in boost. Much richer so you get more energy density. If you're just cruising, yes, but not when you boosting.

Stoichiometric ratio for regular unleaded gasoline is 14.7:1, while 9.7:1 for E85

So when you run a richer ratio for E85 you get more energy, hence more power, but you use more fuel. Methanol you use even more fuel but you cram even more energy, hence even more fuel.
