Now, I know that E85 has had a bad rep and until recently I dogged the fuel as an MPG loser and an inefficient garbage fuel that I would never touch. But I have been doing some reading, and the consensus is that E85 eats up rubber seals, corrodes fuel lines, and gives poorer fuel economy because it's 85% ethanol, but it has an octane rating from 100 to 113. Has anyone here ever tried it in moderation for boosted or nitrous applications? On other car forums, some people use it for turbo charged applications. If some people are willing to poor a couple gallons of pure Toluene or Xylene into their tank, could two or three gallons of E85 safely increase the octane to 95 -97 without damaging the seals? I remember there being an ACR converted to use pure E85, but has anyone used it in mixed form, say 3 gallons in a full tank? I would like to use it to safely bump up my nitrous shot to 200 without pulling timing, or as a way to avoid meth injection if I supercharge later. It's cheaper than 93 unleaded, race fuel, or toluene, and a bump in octane would be sweet. Wiki says this: "Because of the lower heating value E85 has a cooler intake charge—which, coupled with its high stability level from its high octane rating—has also been used as a "power adder" in turbocharged performance vehicles. These modifications have not only resulted in lower GHG emissions, but also resulted in 10-12% power and torque increase at the wheels."
