raising compression?

ive been considering buying cp pistons and carrillo rods for my car as well as porting the head. I know really none of this is needed but i really would like to push the upper limits of the car and be sure nothing will break. I was looking at cp pistons and of course they let you get a custom compression and this brought up the idea.

Would it be beneficial to raise compression to say 11:1 or maybe higher and still run stock turbos?

i think e85 + 19psi on stock turbos + 11:1 compression + a head port would be pretty amazing
