E85 with evo7 fuelpump?

[snooopy365]

Hi,
just a simple question: what exactly will a evo7 fuelpump do if I force it to suck E85?

I heard a few times "densos didn`t like E85" but never get any information why?

Thanks guys.

You'll need to flow about 15-20% more fuel to comparable with regular gasoline.

I.e. regular gasoline you burn 200 ltr/hr. You would need to pump 230 ltr/hr. To provide the same amount of fuel energy to the engine.

sorry I should hav mentioned that, I don`t want to use that for high performance application!
Its my 16G powered Daily Driver (converted NT)

would be nice to know how much power I could make with that fuelpump, but it also ok if it works with very low boost (right now running 16PSI boost and 450cc injectors @50PSI fuelpressure)

E85 is dirt cheap (compared to gasonline, here in germany... 1.50Euro per liter highoktan but just 1euro per liter E85)

Do you have a wy to tune the car? I doubt those injector and pump will allow for much boost. I'm running E85 on my 720's and a wally 255. I amhaving to add meth injection at the TB elbow to keep IDC's below 95-100% at 24psi... You can do it, just watch everything as fasr as AFR's and duty cycles closely.

My first tank was last week and i still had a few gallons of pump left in it and it was doing fine./ Now that i'm on tank # 2 there's even less pump left in it and i'm again rasing IDC's and starting to run out of fuel... I'ms tarting to think a mix of 12 gallons E85 and 4 gallons of 92 pump is what my car will run on. With the cold mornings here my car doens't like to start on E85 (acts like it did before i mapped all the cold start, coolant and air temp maps on pump when i went full on stand alone EMS)

I say try it, i don't know much about denso pumps, but i'm sure with everything else being engineered for at least 20% ethanol since the early 90's, your denso pump should be fine

For the record i'm at an additional 24 - 26% fuel through out my maps.. i raised them by % so that i could keep track

right now I`m only able to use MMCD and my S-AFC.
but custom eprom is not a problem at all and hopefully I`ll reinstall my EGT guage soon (changed header, had no time to drill the hole )

btw. I`m very pleased that your actualy able to understand my sucky english
