E85 or 100 octane

I am seeing impressive gains. Since I only have access to 91 it's a huge step up when mixing 30%. I love it. The power difference is amazing.
 
Did some more logging this morning on the drive to work. Seems cooler temps required a bit more fuel and while it was still well within capacity of the fuel system just the amount of change I noticed from 90f to 70f if be wary of wot pulls when the temps get down into the 40s and 50s. Particularly before the engine temp warms up.

Torque showed about a 40 wtq gain which I was skeptical of till I went to the track and knocked 4/10ths off my 1/4

My car will not give me full power till coolant temps are over 180. Had zero issues this winter even in subzero temps.
 
Glad to see you guys are backing up my claims with real world testing. Great job!
If you guys want to get to a 50/50 mix you'll need to upgrade to the dual in tank pumps or at least to an upgraded in tank pump and boost referenced fuel pressure regulator.
I wonder if just taking the stock pump setup, drilling a hole for a return line and then putting in a fuel pressure regulator would work. The key is to force more fuel in by raising pressure and referencing it to boost.
One of you crazy guys try it out! :)

Mike you selling the dual in tank setup yet. Im seriously thinking about trying the 50/50 mix. If love to go full on e85.

Just added 4 gallons of e85 excited to see what happens

Are you running a e30 tune? If so you should get a fuel tester and find out what you are putting in. I found out my e85 is actually only e65. Since you have to fill on the slowest setting to achieve the proper mix. At stations that have a mix pump that is.

Do you know of any long term degradation of the fuel system from using ethanol? I'd assume ford built the system with the idea that ethanol is in our fuels. Also is there any reason why they won't make a flex fuel ecoboost?

I sure am, they've been avaialble for awhile. The key is I don't have a plug and play harness but it's very easy to do the install.
I can supply you with the billet hat and pumps and you will use your own plastic bucket. You'll need to tap into the factory harness for trigger and to give fuel level. I can also provide a pump harness with relays and battery cable along with a pressure switch to turn on 2nd pump at 3PSI.
I can also sell you an AEM FPR, I can also provide the fittings and line to complete.
Still some engineering but not a half bad job.

Long term usage of E on regular cars (Subies, Evos) have shown no usage issues, the lines are the same for north and south America, South America some contries only run Ethanol fuel (sugar cane produced).
The only line that will be stock will be the return plastic line (easily replaced). You will be provided with enough line to go from tank to FPR (mount off passenger side rear head) and from FPR to the DI pump.
 
No just my 91 tune gonna log some and see how things look. That way I'm not depending on the octane boost.

But I plan on going with a 3 bar, t state and switch to e85 so I'll wait till I have that all ready to go. I don't like switching tunes alot .

What fuel level does the low fuel light come on at.  I was playing with your calculator and if I could get 2 gallons 91 e10 plus 5 gallons 100 octane non E and 3 gallons of e85 I would have 10 gallons of 100 octane @ E28 for around $55

You can't mix race gas with e85. It's a no go on all the boosted forums. Reason being 100 octane is hard to light and when you add e85 which is also hard to light it leads to issues. Stick to 93 and mix e85. The ethanol is enough of a octane boost.

I know my low fuel light comes on around 30 miles to e. No idea how much is in. Maybe 3 gallons.

Once I got my e30 tune my car felt like it grew 2 more cylinders. You will never go back to your 91 tune.
