E85 vs THE REST!

[paddy351]

I saw you can drill out your metering block .

[blueoval]

5-7ltrs u could get away with. 35l like graham used on an untuned and unprepared car is asking for trouble.

I find with eflex i run an extra 5ltrs in my mix to help compensate for lower potency batches of fuel. Never heard my car ping or cough doing it this way.

how much it cost to make yourself paul? Setup etc?

you need to buy the E100, you will need to find a supplier, E99 or E98 unless u have a licence that is the best u will get. get the VP Racing M2 Lube $20 depending where u buy it, (1 bottle treats 200L) and then whichever you want to mix it with. Caltex Vortex 98 or BP 98. don't use Shell it already has ethanol in it. you can even use a race fuel. just do 10%, no point going 15%. plus it makes the maths easier.

setup is 3 x Bosch 044's, 8 x 1600cc injectors. that we know is good for at least 1200hp at the engine. with the 6-cylinder get some 2000cc injectors.

later this year we are going to do a little more testing, try running the Capri and the Outalw 10.5 car on ethanol without an intercooler. will be interesting to see the effects on power and performance, with/without an IC and ethanol vs methanol.

big mixes need to be tuned but a small few ltrs on 98 nets a good result or as a safe guard against pinging ( this is for newbys)

it is a good octane booster. 5% pure ethanol to 98-octane brings it up to 100-octane. 10% probably 101-102 octane.

SPEAK TO YOUR TUNER BEFORE GOING TO E85 OR DO YOUR HOMEWORK

SUmmernuts Yeah !

u love it, the boys loved the Summernuts.

bit of a nugget with the Caltex e-flex stuff. E-flex 72 plus restrictive air cleaners took the car 3-5 secs to get up on boost.

[graham_h]

The Sucrogen race stuff I was quoted $2.50p/l

[XR8 Uterous]

For Melbourne people, Point Cook United now sells E85.

[graham_h]

Good news after my stupidity of filling it up with E85
Did a 200k trip, clear lean bank error code and hasn't come back.
If anything it pulls harder now... maybe cleaned the crap out ?
Dunno.
Next long term project will be to grow my own.
2 acres of sugarcane will produce 4,500ltrs of ethanol (apparently)
Next question is what would be necessary to run on 100% ethanol ?

a liquor license that was the only thing stopping up from buying pure ethanol same thing needed to run pure methanol as E85. from what i have heard pure ethanol uses 20%+ more fuel on top of E85.

How much is that E99 you are talking about worth.

In regards to the caltex E-flex changing from E85 to E 72 between the different seasons, could you mix in extra e 99 to bring it up to E85? In qld as far as i am aware we don't have united E85 so that just leaves me with caltex stuff. The other option of course is race E85, How much is that worth?

Is something like that possible?

Cheers brent

E99 from Manildra is about $450 a barrel, then u have to go pick it up or get it delivered etc. yep, you can definitely mix it to make up the % difference. Race E85 depending on who u get it from can be anywhere from $500-$700 a barrel.

for the Sydney guys, i am trying to talk mates of mine that own a servo @ Northmead to put E85 in, we were talking about it a couple weeks back, if its not too dear to convert they will do it. he said if they do it they will do it right and mix it with 98 instead of 91.

[blueoval]

Good to hear graham. Hopefully there isnt underlying damage. Keep an eye on it.

To run 100% ethanol, I would expect you would need the minimum:

Real big injectors,
bigger fuel pump,
a full tune with either xcal or something.
a dam good tuner.

tell Johnny to set up a bikini car wash as well..that might help sell the E85

then no work would get done.

[OBW351]

I am very interested in running E85 as my new engine i am about to get going in the next month or 2 is running 13.5:1 comp so will need good fuel. I don't have any E85 readily available to me except from caltex in brisbane but from all reports it varies in strength which would be difficult with a carby setup having to retune all the time. I would love to head this direction but a do have a fairly stable supply of avgas so that might be the direction to head.

regards brent

get an ethanol tester http://www.jegs.com/i/Quick+Fuel/793/36-E85/10002/-1 it doesn't matter if it varies a few % here and there. you could always get it in 200L drums. that way you have plenty of fuel at the same %. it doesn't vary that much, the Caltex u deal with may have the same in it for a while.

How much would the tune vary so from E72 to E 85? Would it affect it so much on the street? I know for the race track i would set up for the good stuff.

it would just run a little richer with E 72 in it. That correct?

[Giant]

Great video your bro makes it look so easy.

[OBW351]

how long does e 85 last in drums before it is no good.

[Giant]

from memory well seal drum 2 years

[blueoval]

Doesn't the drums need to be metal as well, not plastic?

[prasac]

thanks Matt, well setup car makes it look easy

short term - couple months, plastic is fine we have some in plastic drums for a few months.

long term metal is the best. you also need to keep the drums etc off the ground so they don't absorb the water in. we have tested some with water in it, didn't really even make much of a difference which was surprising.

we just put the drums on a pallet and all is good. i have heard a couple years if it's stored well, i personally wouldn't push past a year.

[graham_h]

The only "kit" you need is 30-35% larger injectors. Using injector pulsewidth converters to run E85 is a bandaid solution and is fraught with the danger of running out of injector at heavy throttle openings (which you most likely will).
There aren't too many cars out there with 30-35% reserve injector size capacity....
Any modern ECU will happily adjust and fine tune to E85 with larger injectors.

Quote from Here

So maybe all I need is bigger injectors (until the stock fuel pump packs it in)
Now what type of injectors will do the job ?

[dieseltrain79]

You will need to uprade the fuel pump as well . Better off in the long run anyways as you dont want the stock one to fail and lean it out under full load , as we all know the factory ones WILL fail eventually .

[graham_h]

True....Walbro I guess?

[prasac]

Walbro, Bosch, Aeromotive or Weldon all make good fuel pumps.

[ebxr8240]

Yep with good electrical supply...
DON'T skimp on cable size to pump / pumps....
Use std wire to activate relay..
Easy if battery is in boot..

[graham_h]

oh... I thought it was a straight swap out. Looking at a Walbro already installed in sender unit

[F6 JET]

graham ur not going to see the results like us boosted blokes do keep that in mind ok ur n/a and ull pick up a bit

dont skimp on the set up new fuel filter and change it reguarly as the e85 will clean ur fuel system very well and block up std filters more frequently

next get the gs340 walbro in tank can be had for less than 200 of fleebay

injectors are wide spread ask the bloke whose gunna be tuning it what he likes to use and go with that bosch 986's are cheep and any tuner can tune em

can be had for less than 300 off fleebay again

ur fuel hose may or may not like the e85 after a wile keep an eye in it and replace with e85 type hose if needed as the e85 will chew out any old hose real quick

what are the GS340 like with high fuel pressure?
