10:1 would be better with E85 and water injection

Yah I know lower compression would be better haha, I was just wondering if anyone has gotten away or has success story's doing it with 12:1.
No e85 in Canada.(Maybee a pump in Toronto or somthing)
Unless you buy it by the barrel, like race gas.

No big deal guys. Was just a curiosity question.
