just like title says. whats it take to run E85. i got an idea but nothing of hard facts. with what i got in mind im not to worried about mpg. since a 408 with a large single isnt going to be good on gas anyways.

talked to a turbo shop and said it helps keep the vehicle alittle cooler after a run...has anyone else heard or experience that

i noticed alot of import guys switching over to this

 

I believe a starting point would be increased volume,i.e bigger injectors,regulator and fuel pumps.
I also believe that a higher base compresion would help the combustion process in return getting better mpg's.

 

i know the basics of it..but was wanting a comparison to what woudl be needed for whta i want

like 96# injectors seem to be the norm but what are E85 injectors needed...comparisons along those lines

my entire fuel is being redone thats why i ask

 

have to make sure everything in the fuel system is alcohol compatable. not sure if it is allready or not. a turbo 408 running e85 is going to need very large injectors. probably 160's and a serious fuel system. the ability to control low z injectors(standalone?)

i have talked to a couple of guys about their e85 set up's. both of them said the idle tune was a lot harder to dial in with the e85. one of them was on drag week and he said every time they got e85 their idle tune changed a little to a lot. they actualy had to break out the laptop to adjust the tune at times. remember this was from one state to another, localy the fuel might be very consistant.

i would figure about 10mpg max just putting around on a 408 and the ability to run at least 800rwhp without knock. probably quite a bit more. right now e85 is $2.27 localy. not a bad deal for somthing almost as good as race fuel.

if you have some tuning experience i say go for it. if your new to it maybe get set up for it but start with pump gas and low boost and work out the bugs then step up to e85 after you feel confident with the laptop.

 

good info to hear. did you set the truck up for this?

laptop im familar with NA applications but really wet behind ears for boosted

what size injectors you running now or did for the 88 setup

 

96's at something like 80% max dc.

 

In Sweden it is a common thing to do, convert from gas to E85.
I have done it i to my Hoe, works great.

From common experience/knowledge, look at supplying the engine with 30% more E85 than you would with gas.
How to acomplish those 30%, I donīt know. (in your application)
Here a common practice is to crank up the fuel pressure, and only replace injectors if really needed.
Increasing the fuel pressure would be a good thing for atomisation and propably make the engine easier to tune.

I'm not sure if i'm allowed to link to another forum. I can pm you the details. I have been doing a E85 system while doing my turbo setup and they have a very good article on it. E85 isn't as corrosive as what most people think. Only with a high amount of water in the system (10%). Dupont has released articles on it. Most newer EFI vehicles can take it. The only problem is that E85 will clean ALL of the junk out of your lines and tanks. So changing your fuel filter a few times after switching is a must. Large injectors and at least 2 or 3 fuel pumps if your going for big numbers.

 

I would love any info you can give me, feel free to PM me

 

post thta info up if you can. im sure alot of us would be interested
