e85 isnt = to c16 or c10 or c105 or c100 0r even c98 cotane e85 has a very low octane rating to say e85 has a high octane rating is VERY misleading and means some one does not understand e85 and how it works , e85 works most from its cooling of the charge effects not it claimed higher octane
100 octane fuel in every way will out do e85 and 100 octane fuel would be 100% safer then e85 , cost more yes but how much 100 octane can you buy for the cost of an engine and install ???????
If you added e85 you would need to retune the rueling , if you added 100 cotane you would not need to change the fueling and on a stock tune you would be safer and the focus would add its own timing for the 100 octane fuel to be able to get the gain out of it but only the amount needed and still keep the engine safe
