In my country we have 100% ethanol fuel, 93oct and 100oct gas.
We have some cars that run e100 from factory and those cars usually have 12~13:1 CR. Unfortunatelly we don't have an e100 version of Duratec.

All modified cars here (FI and NAs) run e100, very very few run gas.

I started (Tom's tune) to tune my Focus with e100, 30lbs injectors were needed. As expected, the car gained good power, a lot of torque from botton to high rpm.
Cons were, the guy from gas station was becoming my friend lol, cold start is bad, have to turn the key 2... 3 times to start, and wait at least 2 minutes until I can start moving the car. So, I went back to 93oct.
I think with 10:1 CR it's not worth to run e100. With a 13:1 CR engine it would be much better, would improve mileage and make more power.
