How did you end it? Did you concede that you're wrong? You are. Ethanol is less efficient and less powerful in naturally aspirated engines. Go find out what anyone who switches from gasoline to E85 reports in mileage. Flex fuel vehicles are a joke and yes they do retune to account for E85. If you honestly believe it's better then I'm sure you'll agree with zoom44 that hydrogen is a great fuel.

It is not less effecient, fuel mileage IS NOT a measure of effecieny when you are comparing oxygenated fuels. The AFR of ethanol is about half that of gasoline. 6.5:1 ethanol is the 12.5:1 of gasoline.
I don't think hydrogen is a great fuel at all....

part of the volume of the fuel (the gallon part of mpg) is oxygen which is not fuel so mpg of an oxygenated fuel isn't really fuel mileage.

Even if you subtract the volume of oxygen from Ethanol having to run double the volume to reach stoich means you have to burn a lot more ethanol than you would gas to have traveled the same distance.
Now can we please move this to a different thread, as was already requested by paul, or drop it altogether, as was requested by several others?

Here's a neutral source to get info from:

You are trying to alter the results by saying it's oxygenated. Fine. Give me some unoxygenated alcohol. Better yet just oxygenate some gasoline with no other alterations to the structure of the fuel and then let's compare numbers. Show me where you can buy these.
If mileage isn't a measure of efficiency, I don't know what is!

I'm of the opinion he will continue to change the subject or quote biased sources (drivingethanol.org - are you serious?!) when he's faced with facts he can't refute.
It's the precedent he's set so far.
In other news, the Axial thread is many magnitudes more polluted than this.

Someone whip out a crystal ball and tell me if the 16x will physically fit in an RX8. Or if they are bringing the RX7 back. Or if LSx small blocks will fit like they do in the FD's. New to this rotary thing but I kinda like it 
2 pumps? It's all electronic now, isn't it?
That's what I heard. I'm looking at a diagram actually and it appears that they are like a two stage affair. One pump is feeding 4 lines and the other, 2 (Probably the more centralized ones for the apex seals).
