However, you can make that power with less chance of it letting go due to predet. Also you can stretch out the lifetime of that motor if you are running less boost by using more timing, which is safer to do with E.

If quenching hotspots are the only issue, then, yes, that follows.
Also, if E85 has a lower stoichiometric ratio than regular petrol I believe that translates into more potential energy (i.e., combustion pressure) to get out of it, so that could be contributing too.
I have no idea what the actual mechanical tolerances are on a stock VQ37HR longblock, tho...
Are there any confirmed breaks from overpower as opposed to detonation?
