Are you Running E85!?!?!?!?
Are you Running E85!?!?!?!?
Who is running E-85 ethanol? Do you like it, what kind of numbers are you putting down? had any problems? i am getting tuned for it next week by vince...thanks.
its good. my engine temps have gone down by almost 10 degrees. use to get like 27 miles to the gallon now i get about 19-20 street and freeway combined. Haven't got it dynoed yet but i can feel the difference. only down side is when i first start the car up in the morning it stutters a little.
There's ways to make full E85 work on bolted cars but it makes them less powerful down low compared to a blend. I also so no difference in top end power going from a blend to full. I would stick with a blend unless you plan on getting the ZZP cams with the injection lobe modification.

This.
E47-E60 seems to be the sweet spot.
On full E85 with just a downpipe and a tune I put down 314whp/388ft lbs on a dynojet here in Green Bay. Since then I've retuned for E60 and the car is much much faster than on 85.
2g E85+1g 93=E60
This is what I hear. I run E60 cause its easy for me remember (2:1)

Get some kind of a intake mod done and add a little more timing/boost and you could see numbers closer 350/400
Click on the graph below. It is interesting to note that the blending response of RON and MON as a function of ethanol content is highly nonlinear. There is a substantial octane improvement between RG and E10, and between E10 and E50. However, between E50 and E85 there is very little difference in either RON or MON. So basically the perfomance gains from an E50 blend to an E85 blend is very very minimal and almost not worth the headache for fueling concerns. I highlighted the compared octane numbers in gray in the graph. Notice the R+M/2 rating. E50 is only .2 octane lower than E85.... hmmmm
Keep in mind with this graph that RG=regular gas 87 octane no ethanol, HO=91 high octane no ethnnol, E10=90% 91 octane/10% ethanol blend, E50=50% 91 octane/50% ethanol mix, E85=15% 91 octane/85% ethanol blend.
Also for those that may or may not know, RON stands for Research Octane Number (widely used in Europe, octane ratings tend to be high because the tests simulate fuel performance under low severity engine operation), MON stands for Motor Octane Number (rarely used outside of a chem lab, and octane ratings tend to be much lower than RON because the tests simulate a more severe operation that might be incurred at high speed or high load), and finally R+M/2 which of course is literally RON+MON/2 which is used in the US and Canada as a standard for rating octane in a fuel.

It might be a little more helpful to actually post some info for folks to see.

Same for me using E35 in my 16 gallon tank. The ratio is easier to keep up with on my fuel gauge dash marks.

No I hear you. Most are most definitely a little on the lazy side, but I'd just rather give consistant and accurate information when possible. Sometimes things get confused and misconstrued when multiple sources are being referanced
cuz i cant afford a clutch right now. lol! its the first tune i got from trifecta. Drew said vince could go more agressive, but for now im good untill i get my clutch.
no 91? Either way, seeing as how you have E30 available in your area I would personally just stick with that to be honest. No blending, no containers and no math involved. Just pull up to the pump, fill up and and be on your way.
whats the point of e85 besides potental for more power? its cheaper yes, but u get quite a bit less gas milage, which in the end makes it just as expensive as normal 93. So why do it?
