Can the M2 run on pure E85 without any hardware changes?

No.

The owner's manual specifies fuel requirements -- especially for the highly tuned N55 engine in the M2. Engines and fuel systems need to be specifically engineered for E85. Read up on those modifications:

It can't supply enough fuel. The lines/pumps are fine with using it, they just can't keep up with the demand.

I see that slot of people are running a mix that roughly equals to e30. Is that an estimated maximum ethanol for our system?

On my M2 manual (EU version) is written to use max 10% of ethanol mix.
