Anyone running e85? On ram?

E-10 and E-15 are one thing. E-85 is mostly corrosive alcohol. It entrains water (literally sucks moister out of the air until it achieves saturation), and can flash to vapor, causing vapor lock under pressure in high ambient/op temps.
Yes, the pros run ethanol, but a stock, or even modified stock engine is not purpose built for ethanol.
BTUs are awful as well.
So you'll burning twice as much fuel for less mileage.
But if its just ragging down the road, and you can afford the tear down and rebuilds, go for it......
If the 5.7L were going to predictably achieve its full estimated service life on E-85, don't you think FCA would have claimed it for greenie weenie points with Uncle Sugar?

To my knowledge only the 4.7L is certified to run on E-85.

Interesting, thanks for your input, it will take a lot of money to make a hemi 1500 fast at the drags lol, ill prolly stick with just bolt ons, cams, i may still try e85, i dont mind changing out fuel lines, on just bolt ons, im sure stock fuel system will hold, getting a special tune and run e85 for the gains may be nice. later on down the road, i ll see what the options are for e85.

I don't understand why anyone would want to run E85, what am I missing?

Power.

My Zl1 easily gains 50hp, up to 100 hp depending on tune and cam. Unlike others have stated, it does not ruin your engine if it's set up correctly, and the cost/benefit is a plus for power, it's a wash for economy: one generally burns 33% more corn over 93, but it's a wash if it costs 25%-33% less. The key is, as corn is hygroscopic, to not let it sit in a tank for any length of time, and to run straight 93 every 2-3 tanks of corn to keep the system clean and eliminate any moisture.

It's really just the opposite:

Most fuel lines today can handle E85 all day long. The idc (injector duty cycle) will most likely be over its limit and there will be strain on the pump...possibly the fuel rails could be a bottleneck as well.

Get your bolt-ons done first before worrying about combustion mods, there are much more effective methods for controlling detonation and pre-ignition than corn-gas in boosted or high comp applications.

Coming from a little four/six popper rice burner that makes power in a small window myself in a previous life, you're going to find labor and horsepower/component mods extremely different.

You're right, ive never messed with a domestic truck before. And even with boost truck still be slow, maybe low 14 in a 1/4 , but like you said, ill start with bolt ons, tires, maybe get a clean tune, and stick with pump, until i get a better picture of what ill be getting into lol

Ive seen, camaros, mustangs on bolt ons , stock fuel system running e85 consistency, but i would also think it would max out lol

Easily gains 30+hp, im addicted to gains!

108 octane for cheap, here in SoCal e85 is $2.85/gallon
100 octane at the pump is about $10-$11/gallon
My 10 Silverado is flex fuel ready so I can pump e85 in any combination and I don’t have to do crap. I do it to keep the top end clean and back when gas was almost $5 couple of years ago e85 was still cheap.
It makes no sense on a stock vehicle, but if you have some long tubes + cam is cheap power, and/or if you’re pumping NOS or have FI is also cheap insurance and more power.

There are great resources out there with foundations laid even N/A for these trucks similar to most imports, the traditional turbo is pretty uncharted territory however due to engine placement in the truck chassis along with minimal aftermarket piping support.

My point bro, i plan on doing bolt ons, cams , and small shot of nitrious!

Just so we're clear: Starving your engine of fuel will be catastrophic. I don't know about the Mustangs you speak of, but a properly designed system (In LS engines that can include pump (dual or triple) new lines including a return, ffs, injectors, and possibly rails, cam, headers etc.

I've seen a lot of idiots just bolt stuff on, and...kaboom.

Lol well i didnt risk it, i upgraded my fuel injectors, fuel rail, fuel lines, fuel pump on my s2000 to go e85, ill mostly likely do same with ram hemi.

My Dad and I own a large farm in south Ga. We are surrounded by other farmers as well. It is kinda a known fact in the farming community that the ethanol subsidies are on their way out. We use to have several gas stations that sold E85 where we are stationed now. Left for 3 years, came back now there are 0. Closest one is an hour away. Cheaper to buy race gas.

Out here west texas, e85 pumps are popping up , and we go and fill up by the barrel lol

It makes more power than pump gas because of a higher resistance to knock. So you can advance timing more.

My 3.6 is an E85 ready motor so what can I expect if I used E85? More power and better mpg? From what I have read I will get poorer mpg making it a wash cost wise. I'm still confused with conflicting results posted.

E85 will LOWER your gas mileage, because it take more ethanol to complete combustion. E85 will INCREASE power. Because it has a higher resistance to pre detonation (knock) so you can advance the timing.

More advance timing = more power

What if I don't advance the timing?

No one wants the **** here. Sure it’s cheaper, but your mileage goes to ****. Unless you are running it to strictly make power, no gain. From a business standpoint, which is the way I look at it, it has long outlived it’s usefulness. The whole process of producing ethanol from corn is a big joke.

Then it makes it completely pointless. As said before E85 makes more power than gasoline. At the expense of gas mileage (to the point where I get about 8mpg from a turbo 4 banger OUT of boost).

So if you dont at least take advantage of being able to advance timing. It makes it 0% useful, rather than 50% lol

Lets see if I have an accurate understanding of ethanol added to fuel for our cars and trucks. Its purpose is to make cleaner air even though we burn more fuel to get cleaner air plus the pollution from fuel burned to cultivate the corn and the fuel to turn the corn into ethanol and transport it to refineries. We end up paying more for food as this raises the price of corn a major livestock feed. We also end up spending more for fuel that can cause damage to engines and fuel systems that must be designed for this very caustic fuel so there must be an upside that can justify all this expense and all I can see is more money for corn farmers and maybe air that is supposedly a little cleaner? What, if anything am I missing?

What do u mean technically a hemi isnt set up to run e85? Chevy, ford motors and honda run on e85, u have to changr out to bigger injectors and fuel pump, and get a special tune, is that what you're referring to? Or hemi simply cant be modified to run e85? I run e85 on my s2000 aem v2 with fuel flex sensor. Fuel flex sensor lets you use pump or e85, it wouldnt matter how much u use of each, it can be mixed

I didn't say anything about it being modified to run E85, but according to FCA and your user manual (see pages 673-679 in your user manual)anything over E15 in a non flex fuel engine could cause problems and void your warranty. Can you modify it to run E85? Hell yes. Do I want to run anything with ethanol in it? No not really. If it was up to me ethanol free would cost the same as E10 and I wouldn't ever buy gas with ethanol in it ever again. I hate being forced to pay an extra .50 cents a gallon for ethanol free.

You don't have to advance the timing the truck does it for you... there's a sensor that lets the computer know when you run E85. That's why you are suppose to only switch to E85 on an empty tank and not mix with standard gas.

Anyone running e85? On ram?
