E85 or pure bioethanol is presented as fuel with better performance and better efficiency. But it is not true! You have to optimize and increase Compression ratio (some turbo engines with E85 have bigger than 18:0). Turbo is helping to optimize A/F ratio which is needed, because bioethanol is not so efficient as gas. It has 30% less power (mean 30% efficiency) if is combusted in similar way like gas (if you just switch to E85 in your Z).
And why is so presented as more powerful and efficient? It has AKI or RON over 130! So you can optimize combustion process to use bigger compression ration which will increase efficiency and add power. In Norweigen and Sweden are used D95 buses - bioethanol with some additives is used in diesel engines for get even better efficiency and with its really big AKI index it is possible.

Are you running a stock fuel pump and stock injectors? Because by your sig, it sure looks like you arent, in which case my point remains the same for a forced induction build...

Why it is suggested not to use is fact, that bioethanol with over 10% in GAS is really corrosive and get outside moisture. For this reason is not transported by pipes like gas, or diesel.
All seals have to be corrosive free. It acts really bad with pure aluminum. So engine pistons and other components made from aluminum have to be protected with some non corrosive layer.
VW/AUDI forbid to use 5% or more bioethanol in Gas. But know is law for adding to 10% of adding bioethanol in Europe Union!
