Hi Speeders!

Do some of you have a long experience with E85?
I tried it last week with an adapted tune (Protomotive) and have to say it outperforms easily the pumpgas, holding very nicely high timing with higher boost.
So I see the pros but what are the cons?:
Are they some short or long term issues with E85?
Can we run it all the time with no worry?
Is there a need to come back to pumpgas sometimes?

All input from experienced will be welcome! Thxs.

Besides lower MPG, there really aren't any negatives to strictly running E85. The first question you need to ask though is, what are your power goals with E85 tuning? Depending on how aggressive you're looking to go, you may need to upgrade your Injectors, Fuel Pumps & Fuel Rails.

It's recommended if you consistently run high concentrations of ethanol, that you run a fuel lubricant (like this one: http://www.powerpluslubricants.com/toplubes.html) just to keep everything that comes in contact with the fuel remains properly lubricated.

 

an e85 engine will last longer and make more power than a pump engine. pump fuel is like feeding your car mcdonalds.

 

Ok, as for myself:Mc Donald's sometime but "bio" when possible!

My goal is not to max out the engine, nor the turbos, max boost will be 1,5Bar.
It is a street car, not a drag.

Perhap's a fuel lubricant every several tanks...

 

i have been using E85 for last two years. when you first convert i recommend changin the fuel filter several days after the installation. E85 will lift dirt from the tank and clog the filter up so you can have issues with pump deadheading into a clogged filter. i have seen this happen to several people. im not sure what factory 997tt filter element is made out of but you want to use filters tha are not paper based elements.

 

Its good to run 93 once and a while to lubricate parts in the engine.

 

Thank you Prodigy,
My fuel filter is only 3000km following my engine rebuilt, but I can change it if needed...
How much boost do you run? and max timing? (if you are Ok to say it)

Much thxs,

I didn't even know E85 was available outside the US - the US farmers appreciate your purchase. Without the corn subsidies, E85 would be prohibitively costly.

 

I'm sorry but I wasn't clear, is the car originally setup to handle E85, and you've remapped the cars E85 tune? Or are you changing the pump gas tune to an E85 tune?

If the components of the fuel system are designed for E85, your good. E85 is significantly more corrosive than the 10-15% additive fuels. The internal parts of the fuel rails need to be stainless steal or HARD anodized aluminum. Of course the rubber lines and tank liner (not to mention the anti slush foam) all need to be able to cope.

Not trying to rain on your thread, just wanted to let you know what I found in research for converting a Non-E85 car. Longevity shouldn't be an issue. I have not heard anything about needing lubricants either. Just be aware the E85 can be corrosive to standard aluminum.

 

Haha prob the best analogy of the year goes to you sir.

 

I run up to 2.5bar of boost and up to 30 degrees of timing.

Google Ethanol Brazil

Im surprised you didnt say E85 is like goat milk to turbo cars

 

^dont be silly. e85 still has 15% gasoline in it. if anything it would be more like dairy milk (which btw takes the body a LOT longer to fully digest. some people are lactose intolerant, and some just dont fancy the taste of raw cow milk. its not bad per say, but you can smell the grass the cow ate if that makes sense.

raw goat milk on the other hand is more like c98. its a much better milk for the body. in fact, raw goat milk contains EVERY mineral and nutrient our bodies need to survive. there are some people that live off of goat milk. raw got milk takes the average person 20 minutes to fully digest. there are also other uses of goat milk, in particular soap make from goat milk. soap made from goat milk.

the main reason raw milk (in particular, goat milk) is so nutritious is because it is a live food. fun fact, raw milk doesnt expire or spoil. it turns into yogurt, then cheese. the longer you let raw milk sit, the more nutritious it becomes. personally, i go to a goat farm in Massachusetts every 6-8 weeks and buy 10 gallons at a time ($12 per gallon, with gas and tolls its about $25/ gallon). I immediately freeze 8 gallons.. now here's a trick that i need to share with anyone who wants to do the same..

when you freeze raw milk, you should do it 1 gallon at a time and try to empty the freezer out before doing so. the reason for this is because if you stuff the freezer with a few gallons of milk, it will take longer to freeze. you run a pretty good chance of the milk curdling if it doesnt freeze (or even thaw) quick enough. the temperature on the inner most part of the milk and outter most part has to be within a few degrees of eachother. (see attached pic to see what curdled milk looks like).

now, if your milk curdles, you don't have to throw it away. after all, what curdling means is that the water has seperated from the proteins (fat). this is a great opportunity to make your own goat cheese. and another bit of advice, if youre freezing raw cow milk, the milk with freeze in layers. the creme (fat) will rise to the top. just shake it up a bit before drinking and all is good.


so yea, e85 is waaaay better than pump fuel. but c98 is even better than e85.

the first pic is frozen raw cow milk (see the creme at the top)
2nd pic is raw goat milk. btw goat milk is a little sweeter than cow milk too.
3rd pic is curdled goat milk (notice the water at the top, and the curdled milk at the bottom. remove with a cheese cloth)

 

now that i think about it, gasoline and e85 is a great thing to compare to conventional milk and raw milk.

gasoline is refined through crude oil. crude is a super thick black goo. a refining process gives you gasoline. we can think of this as raw milk being pasterized. the reason pump fuel sucks for our cars is because its not clean. have you ever seen how gasoline burns ? it always leave a black residue. this is carbon. carbon build up is what causes cars to lose power. (this problem is especially seen in direct injection cars). when raw milk is pasteurized its composition is changed. pasteurized milk produces a lot more mucus than raw milk. (thats why your tongue has that wierd taste after drinking milk). thats why your saliva feels more gooey after drinking pasteurized milk.. thats mucus. puss. the carbon that is produced by gasoline is like the mucus thats produced after pasteurizing milk.


ethanol is alcohol. alcohol burns muuuuuuch cleaner than gasoline. its FAR less refined. its pure. thats why the flames are blue. if you take two glass jars, once with ethanol and one with gasoline, the ethonal will burn blue, and will burn longer. the gasoline burns orange/yellow and always leaves a black residue. ethanol is a more pure and organic form of energy , just like raw milk..

so the question at the surface is about e85 vs pump gas for our cars, but the underlying question the OP really has is, do i want to put pump gas milk in my body, or c98 firepower funny car raw milk in my body ?

 

oh and one last thing.

when raw milk is pasteurized, the nutrients are killed. you might be thinking to yourself, how can that be, the nutrition label on the back of my carton says xx amount of proteins and so on..

how can that be ?
the nutrients that are in the milk arent from the milk. they are added to the milk after its pasteurized. so lets say theres 8 grams of protein in 1 cup of milk, while that is factually true, that protein isnt the protein that the cow produced, its protein that was added to it. in addition to bleach among other things (the FDA is soon going to be approving putting aspertine in milk !!)...

thats all for now...

dont get me started on homogenization....

 

I stopped smoking over 20 years ago. Now that I read this I consider starting again and get some of the stuff you must have
