You're correct that you "can" make more power with oxygenated fuel in alot of applications.

Do you not get it? Did you not read the article I supplied. There is no "alot of applications." Any motor WILL make more power if you give it more 02 and fuel in any given time. PERIOD!

A motor does not know if it's in a motorhome or if it's in a chainsaw. It does not matter if it is an 049 Cox motor powering a model airplane or if it's a 500 inch prostock motor. The more 02 it gets the more power it will make.

You can post straw man argument about tuning or certain cams or compression ratio's or whatever. All of that makes NO difference because the more 02 you can give a motor the more power it will make. Period! E10 is an 02 fuel so it WILL give you more power on ANY engine. E85 will give you even more power and methanol will give you even more power and nitro will give you even more power.....
(BTW all engines made now days have EFI which will always keep it in stoichiometry. They arn't even close to 100% duty cycle on the injectors so no you won't top your injectors out with E10)

If you disagree, fine. Post any legit article and I will read it.

Don't let your ego stand in the way of your education.

I think I get it Turtle. An engine can burn more fuel per time if its breathing more oxygen per time and therefore make more power. In order for an engine to make more power the fuel injection system would necessarily need to adjust to decrease the a/f ratio.

The stoichiometric a/f ratio of pure gasoline is 14.7:1. E10 has a stoichiometric a/f ratio of 14.08:1. So the math tells me that the fuel injection system should call for 4% more fuel when e10 is being burned vs pure gasoline. But e10 has about 3% less energy than does pure gasoline so I'm going to expect 1% more power and 3% less mileage out of e10 vs pure gasoline. You'd need a pretty well tuned butt to feel a 1% increase in power.
