No need to worry about 800 wheel on 93. What I mean is that you wouldn't be "safe" on 93 with that blower at 800 wheel. Just run the E85 and be happy with the safeguard it can provide. Trying to see 800 wheel on 93 with our cars is not going to happen without methanol injection as stated above. Even if you get to that, why would you want to risk destroying a motor over saying "I make 800 wheel on 93". I guess I'm not understanding that logic here. Why do you want to make 800 on 93? Because it sounds cool? I'd rather roll on ethanol and feel good about its benefits.
