Someone was telling me that I could mix e85 ethanol with 91 octane to get closer to 100. I was going to run vp110 with 91, but wanted to know if I could get away with this. Thoughts?

E85 is already 105 octane. I don't think you will see anything benifit.
E85 takes a different set-up to work properly. you will need larger jets, alcohol accelerator pump, alcohol fuel pump and fuel cell.
E85 works real well in the right combo, my friend has a sm. block Ford 408 street engine that makes 600+ horsepower on E85. it is worth the change.

Sweet, that would save me a ton of coin in the long run. Thanks again!
