+1 for what he said above.I am amazed at some of the rumours going around about E85.
eats rubber hoses - pre 80's cars would be in trouble, not us
all hoses need to be teflon coated - I run aeroquip pushlok hose-no problems
anything plastic will be eaten - Exactly what is plastic in your fuel system other than the float?
most fuel pumps wont last long on e85 - Tell that to mine! Walbro 255 intank, again no problems
it absorbs water really fast so not good to let sit in tank for a couple days - I've had the car off the road with broken bits for up to 3 months at a time. As long as you leave the fuel cap on you will be fine. A couple of days is nothing. E85 is Hygroscopic though and I would not leave a drum of it sitting around for long periods with the lid off.
and fuel injectors need to be massive like 1600cc minimum. This I do tend to agree with, the bigger the better with E85. I run 1450's in mine and they are at about 75% idc's at just over 30psi on a 50 trim turbo. That said, they idle like stock and still get decent fuel economy unless I throw my right foot into it!
What it will do is pick up all the crap in your tank and fuel lines for the first couple of tanks. You will find that you need to change your fuel filter at least twice in the first couple.
I ran C16 and Q16, and I'm now running E85. I ran the same timing maps as q16, and I just got the a/f on target in the high 11's and low 12's in gasoline scale. I picked up 36 whp from Q16 from 821 awhp to 857 awhp, and it cost 4 times less per gallon. I also use to be a VP dealer, and gave it up because what's the point? Now if you can't get E85 or you don't have anybody with a alch tester, then C16 and Q16 can be your best friends, they are great race fuels. E85 works better than race gas because it lowers the combustion chamber and reduces the chance of knock greatly. It also continues to burn while the power stroke is being completed. This spools turbos faster, and increases torque. I have rubber lines and the only problem I had was the injectors got fouled within 3 months(caused a strange misfire). I pulled them out, sprayed them down with carb/ fuel injector cleaner, put them back in and no issues since.
