Interesting... anecdotally when we fill either of our vehicles with Gull [cheapest] gas milage is crap..significatly..its an ethonal blend...works out cheaper to buy more expensive normal petrol.
So I would imagine its anti power to...you may gain a tiny bit of oxegen...but unless your engine is turn for the lower specific calories of ethanol..you more than likely lowering the output of your engine.
I think that would depend on the situation, perhaps the oxygen effect may be negligible but the cooling effect could be significant. I'd think high ethanol fuel may be just the ticket in a hard-tuned air-cooled two stroke that is running on 'pump fuel' . The extra consumption would be negligible in most non-endurance racing...
Anyway, back to the topic at hand.
EDIT: "unless your engine is turn for the lower specific calories of ethanol" oh, you mean tuned, right, yeah I guess I'm kind of talking about the 'tuned' or suitable part.
