No Free Lunch, hp cid torque gearing

When designing an SBM street engine, to actually be a DailyDriver, one very quickly hits a wall in getting air into the engine at higher rpm. Sure you could install a bigger cam and so on, and the project quickly spirals out of the realm of DailyDriver. Been there done that.
Whereas getting a liquid fuel into her is easy peasy.
Fresh cold-air induction and Oxyginated fuel
are just two ways of getting around the restriction. Which is why my engine has only once ever not burned 87E10. It may not be much, but it lets me use a slightly smaller cam, which has a slightly earlier closing intake valve angle, which then makes a lil more cylinder pressure, which makes her a lil more energy efficient, and saves me money at the pump every time I fill it up. That's a triple win for me.
E10 is the ONLY oxygenated fuel we have locally besides E85. If we had E20, I would happily tune for that.

I went on the hunt to find out how much oxygen is actually in E10, but results are or seem to be shrouded. It depends a lot on where you are and in what season. The smallest Oxygen content I found was 2% and the most was 7.6%
A gallonUS of straight gas is said to weigh 6.3 pounds. To make E10, you would take out .63 pounds of gas and replace it with .63 pounds of ethanol. If that ethanol contains 7% oxygen, that would be .044 pound of oxygen. How many oxygen atoms would that be after disassociation from the fuel, compared to how many atoms of oxygen are in a cubic foot of dry air that contains about 19% oxygen be weight.
IDK the answer to that
