E85 that is. I thought about it last year but was not ready then. I then gambled 6 months ago to use E85 for the mile as a last effort to get the extra power needed to have a shot at 190 mph. Finally in the last couple weeks, I started added E85 in and monitoring LTFT an AFR. Things were looking perfect and still no tune yet. I never dynoed E85 an only road tested. So my injectors are set up to run the extra 30% fuel needed to run E85 and my pump are also set up for it.

I mentioned a few weeks ago, I went under cover and no-one knows what mods I was putting on , mile plans but this one leaked out, so full disclosure now.

Jerry came over to road tune me and also did not know what was on or in the car. He was cool and did not ask either. I had only started to test full E85 and realized that my fuel lines were not going to handle the flow needed (need the flow of about 750 hp for GAS). So I told Jerry that noone knew about this but that I had E85 and wanted to tune for it. He said cool, lets go.

After a few hard pulling runs, I gave up on the lines but Jerry eager to make this work, kept cheking files and making 100% sure nothing was missed before giving up. Bottom line, we spent two hours testing and learning but the gamble has left me with no tune yet. So, still no tune for the mile and kind of stuck in the middle between gas and E85 tunes. Way to lean on E85 and pig rich on gas. Even 50% E85 won`t work, still lean up top. I am making plans to change all the lines but doubt there will be time. Jerry offered to come back and tune for Gas today, as he he is bookd up for the next few weeks. I just added 80% gas back in but car and it is goin extremely rich now, as expected. It was a gamble and worth the try though . Have not given up and will convert but not sure when yet.

I frickin love E85! It is like a Nitrous addiction or even roids! lol

 

parts that you need are on their way to HTX

 

good luck. if you need help during the days to change out lines or anything else. i have a pretty flexible schedule and can help if needed during the day during the work week.

 

E85 will definitely make some good power. best of luck doing it.

 

bring the car to the UK i will sort it !! lol

Good Luck

 

wow so cool!

I fly in on the wed before and can always help if need with the last minute stuff

 

you're always on the cutting edge my friend. 195 in 2012!

 

Just what we need! A drunken AMG going down the air strip. Way to go Brooke!

 

Shardul, HTX?

Sure the love smell of clean burning Alcohol. no smell on the clothes, don need cats to pass the sniffer test either. Pulled 02 sensors out and looked liked they just came out of the box.

Pretty sure that a 10% increase in power was in our grasp and will be at some point but have a few line challenges. The CL fuel system is a tad different than the e55 but the work the same.

1) Have to weld 8 AN fitting on fuel line
2) Change all lines to 6AN min. or 8 AN
3) Go to larger race fuel filter made for E85
4) Tricky part is finding a way to make the small 6mm ID fuel pressure sensor work. It blocks flow but is tied into the ECU to control pressure. I think I have this figured out and a few ways to do it. All this has to be tested.
5) My high pressure pump also has a voltage controller on it , as do the E55`s.
6) What would be cool, if Jerry could figure out how to control this pump voltage in the tune. Then we could change pressure in our fuel curves. This would be really cool! May be other ways, but wires are not my thing.

This is the CL fuel system.




Inline fuel sensor that I have to deal with somehow.


My Bosch 044 pump and filter. Line T`s right after filter and creates moreflow issues. One line goes to rail and the othr back to tank. No good!

 

I don't know how involved you want to get or what kind of room is available down stream of that sensor that is your bottle neck, but have you thought about a possible surge tank? The only thing I am unsure of is since your goal is not short bursts such as a 1/4 mile run or run from 50-130 on the street how effective this could be. Running wide open for such a long time doing the mile I am not certain how big of a surge tank you would need to make in order to not run out of fuel, but you could definitely feed a surge tank after your little restriction using it as a resevoir and then pump the fuel from the surge tank to your rail with another pump to keep the pressure at the rail or maybe just move the pump behind the surge tank so it pulls fuel into the surge tank to keep it full and then draws from it to feed the rail so you could just use the one pump there. This is a bit more work obviously having to add the surge tank and wire in another fuel pump to feed from the surge tank if just moving the current pump behind the surge tank wouldn't work. But as a last resort it certainly could work for you if you can't get around that bottle neck with whatever ways you have thought about.

 

For the pressure sensor just put in two larger tees and put the pressure sensor in a seperate loop. That way it will get a good signal and not restrict flow. Also the FMU for the pump is not actually controlled by the ECU at all. It is its own independent system. If you want it to run higher or lower fuel pressure then all you would have to do is modify the signal from the sensor. You could also add an aftermarket FMU.

 

^ that was going to be my suggestion as well. Should work, and allow unrestrcited flow. This will become the basis of many E85 / 55's is my bet

 

Surge tank is all out race! Miight be a good idea, if enlarging lines still has issues. I think a #8 line may also work like a surge tank, by keeping extra fuel in the larger 15 ft line. Will test and let you know.


That is my plan on the sensor, is two use 8 Y fuel blocks and keep the sensor happy. As far as changing signals and electrical stuff, I would have to be taught all that. I like th ideas.

All the fuel lines are to small for E85 at my power level. Not just the sensor but all lines. They are 6mm ID or a tad under 1/4". You just cant flow another 30% fuel through them to support E85. They all have to be changed out to be safe.

Well, she is addicted to Alcohol! Been adding gas back in and maxed out the LTFT and now have codes Po172 I think. System to rich now! It is right on the lin but at 25% LTFT, you will code. Just like a drug addict, may have to add some E85 back in to keep her form going into wihdrawls. hehe

I did a WOT to check AFR on gas and may be running better on gas but again, E85 was not tuned and not enough fuel.

 

Exotic you are a nut! Lol good luck with the beast!

 

I love E85 and this thread!!!
I never committed to converting my supras over cause I had a hook up with a VP fuel dealer but The rest of my crew loves it and makes sick power on E85. I never seen a motor ping yet on it even at extreme boost levels.But the consumption is insane.

SUBSCRIBED!

 

Why not run a second pump in parallel with the stock one? Feed the fuel rails from opposite sides. Run both pumps from the factory pressure sensor.

 

Has anyone has problems with E85 ??? I know for marine use the 10% ethanol blend fuel can cause horrors in the fuel tanks and when the slightest of moisture is introduced it can cause "phase separation of the ethanol from the gas and create globs that pick up all the particles and clog fuel lines .


Here is a quick link

In for the progress! Awesome work! You'll absolutely pick up some major power with E85. Good luck!

 

The two pumps I have should more than handle the demand, If not I have another inline pump waiting. The 6mm Id fuel lines can not handle the 30% extra fuel needed on top of making over 600 rwhp on gas.

I will have the new system ready soon and new fuel rails. Just some minor work left to complete.. I logged a lot of data and was real close to having a full blow E85 car. I ran on E85 for a week and made a lot of WOT runs up to 135 mph and know what it can do now. I am still running some eE85, as I am still not tuned and stuck between fuel types. A little goes a long way , when mixed with gas.

I know this is a great fuel for our boosted motors and just wanted to see if we can all start taking these cars to a new level.

1)E85 is damn hard to detonate. Very slow to ignite but burns much faster that gas.
2) 2.60 a gallon only
3) Great at cooling the air charge and EGT`s.
4) You can add huge amounts of timing or boost on it over gas
5) It burns clean, as in no carbon or fouling of 02 sensors
6) No small, if you are catless
7) Since you need about 30% more, the extra fuel to air ratio will cool charge even more.

Just a few quick features off the top of my head.

 

Will be running 100% E85 by the next mile in March. Fuel supply has been fully upgraded now. 8an Starlight hose all the way!
