has anyone or any tuners thought about E85 for the LNFs yet? i hear alot of good things about it. For the tune i believe the fuel just needs to be remapped up about 25% from bottom to top and your good to go but you can also throw mega timing at it cause of the high octane.... Trifecta just unlocked the fuel tables so i know this could really be a decent upgrade for the tuned balts. And if you have tuned a coblat you know how much these cars love timing advance. idk just a thought. I know that E85 here in the houston area is like $2.00 a gallon so i would save about .85cents per gallon. Could make like a $12-$13 difference on fill ups! and the extra power?? seems like someething that needs to be looked into from my point of view. Any info on this?

 

make sure theres corn juice everywhere you go

 

yea thats the only downfall that you may be limited on the locations to fill up. I know there is about 3 places that carry it around my house

 

I was thinking about doing the e85 conversion but there only 1 location near my house with it and none on my way to school so i stopped thinkin about the conversion

 

noob question... E85=110oct??

 

until a complete fueling solution is found and tested out in the market. i wouldnt suggest it, as e-85 requires 25-30% more fuel. and cardelino, e85 is 105 octane

 

waaat? 110oct is freaking 6.99$ here in south florida!

 

Yes, but 110 octane racing fuel has much more energy per unit than ethanol. So while the octane is nearly the same, you get about 20% less energy out of ethanol. MPG's will go down even with a tune for it, but you can get nice power gains due to the timing and cooler charge.

 

yea the actual energy it produces is not the same as a 110 octane race gasoline but E85 does make more energy than the premium fuel you get at the pumps. I would like to see what kind of power we could make out of it. Some people say they were seeing a 20% fuel milage decrease but idk. its different on each vehicle. it may not be worth it in our caqrs but its worth a try

 

We've run E85 in my LNF with a couple different configurations. It doesn't work for a couple reasons-

1. The increased fuel flow is not easily met. With stock fuel pressure, you will run out of injection window at less than 275whp. With raised fuel pressure and bolt-ons, you will run out of injection window once again. The 4%-5% power gains from running E85 are outweighed by the power loss from poor combustion caused by improper injection timing and/or reduced cam timing potential when running long injection pulses.

2. LNF's don't require 105 octane. When I ran 11.99 on the stock turbo, I was running 93 octane. We ran 110 a couple times, but saw no gains on the dyno.

The only configuration that would benefit from E85 would be raised fuel pressure on a lightly modded setup kept below 300whp. Basically, you could bump a 275whp setup up to 285whp.

On another note, I have read that the mechanical fuel pump is not designed to extensively run E85. However, I can not verify the validity of this claim since we only ran it on the dyno.

 

So would you say meth isn't really needed for the LNF either?

So far I've held my ground in saying that you dont really need another point of failure on the car, especially if the stock turbo is being taken to its limits without it.

 

I am looking into getting a meth injection kit, and running E85 as my additive instead of methanol. I have an E85 Gas station in my neiborhood

 

Sounds like a huge PITA for nothing. Why bother?

 

we only have 91 Oct around here, injecting E85 will help in the arizona heat, and I can run a bit more timing. Installing a meth kit isn't that hard, and E85 is cheaper than methanol. I don't see the downside you are seeing.

 

If you are injecting meth or E85 somewhere other than through the direct injectors, then you can shorten the pulsewidths which can be beneficial, especially on cars over 325whp. The hard part is getting a consistent tune. Typical meth kits are anything but consistent.

 

And this is where I hope ZZP can help me out

 

So it is good for something... Just not as fuel lol.

 

Lol. It's still fuel when it is injected somewhere else...

 

Is the LNF's fuel system compatible with E85? Have read all the stuff you have to convert and upgrade for corrosion resistance in earlier vehicles. Wouldn't even risk it if you aren't 110% sure.

 

what about tolulene?

 

Has anyone thought of taking the mopar turbo toys add on fuel system or something like it and adapt it to our cars to run e85 or race fuel?

 

Without being able to control fuel delivery you're going to do nothing but hurt the power of the car. It will smell cool, be "green", and keep in the internals looking like new...nothing more.

E85 is roughly 105 octane.

Its cooling characteristics and resistance to denotation is amazing but without the ability to tune for it, it will be a waste of time.

Fuel system components nor materials WILL NOT need to be changed to accommodate for E85.
