E85

[levinracer]

E85, who's using it? i am now converted to E85 and i am impressed with what it has achieved... even on a little 1800cc NA engine. and the flamage is awesome at 9000rpm!!

whats peoples thought on E85?

brad

ps. and its CHEAP! (although you have to burn a fair bit of it!)

[35R]

i am looking into it now. it's funny, some people are dead set against being "on the corn".

with the e85 deal that holden are doing with servos (caltex?) we'll be seeing a lot more e85 outlets very soon. the smart tuners should be getting ready for a whole new wave of opportunity.

[Kyle]

Isn't it made from sugarcane?

[35R]

i think it is here, but mostly from corn in the USA

[levinracer]

Isn't it made from sugarcane?

yes it is, i tried pump E85 and race E85 and it made little difference at all, so i think the .99c E85 is definately the go.

make sure you find someone who has methanol tuning experience, the fuel mixtures are a hell of alot different to race fuel or pump fuel.

you dont wanna be someones first attempt at this fuel!!

[Aeron]

Whats the fuel consumption like on E85?
I hear its not too good??

[levinracer]

E85 out of the pump at rozelle averages .99c per litre, my engine require approx 33% moe fuel. so it is costing probably the same as 98octane.

engine temps on the dyno dropped 15degrees, it made more horsepower and held the power right through to 9500rpm, where as before power peaked and then dropped off.

it smells awesome, burns your eyes and nose, flames out the tail pipe and you wake up in the morning and you can still taste it!... i seriously dont know this can be good for the environment!

[Kyle]

My concern is how is it on fuel lines/gaskets/rubber shit/etc????

Also, Mate of mine buys it in 200L drums from CSR or Manildra direct for I think he said about $260 including freight

[lautray]

I was thinking of giving it a go in the SS a while back... my injectors can handle it but not sure about getting 33% increased volume from the walbro :doh:. Also, it'd have to be more readily available around the 'burbs.

its all a myth in my experience so far, i have had it in my fuel system now since january and it has not perished or corroded anything as of yet. i personally cant seeing it be a problem. if you are concerned flush your system after each time you use it.

i wouldnt mind your mates contact for the ethanol, i would like to have a go at mixing it myself

ok, well my thing had 365cc injectors on pump gas and they were at about 70% duty cycle. i put 550cc injectors in for the first run on E85 and they ended up being max duty at 5500rpm. i had done a bit of sniffing around some honda guys running similar engine configurations and they were running 1000cc injectors, so i bit the bullet and bought some 1000cc's and tuned it with them. these injectors are running at approx 60% on the E85, so in hindsight 800cc's probably would have been enough, but the 1000's are working well and the are very controlable at idle, so 1000cc's it is.

i didnt change my fuel pump, it's just a VL tubo bosch pump, E85 does want more pressure though

brad

[Kyle]

1000cc injectors on a corolla just doesnt sound right :D

I'm running Bosch 42lb greentops (not sure what cc that equates to) at the moment & see ~68% duty cycles at 7000rpm (383). I think the Walbro fuel pump supposed to be rated at ~550hp & it may be pretty close to maxed out as it is.

To ensure availability of the fuel for Holden's vehicles, Caltex Australia’s General Manager Marketing Andy Walz said the company had signed an agreement with Holden which committed to installing pumps in 30 metropolitan and regional service stations later this year, increasing to 100 within 12 months.

Not sure about NSW, but i've read stories that suggest 60 servos will have it within 12 months.

It's coming to a servo near you.

[BLK 1T]

So the drag race tuners will be popular. IIRC when the supercars went to E85 last year one/some of the teams employed drag race tuners to help them get their heads around the increased consumption.

[JEVO]

I've been running E85 for 18 months now. I had an in tank pump upgrade, 1000cc Rochestor injectors and completely stock motor, ecu and turbo. Even the air box and plugs are standard. This produced 255kwatw and around 400nm torque. A 98 tune yielded 210kwatw. We have put 1.5 years of constant tuning and monitoring into this vehicle, the results are awesome. My car was a test bed for stock ecu maps, which are now the based for similar vehicles.

Now with a bolt on replacement turbo and all the same we recently got 290kwatw backed to 280kw@23psi boost with 500nm torque. Fuel supply is now an issue, budget permitting this will change before Superlap. I see so people change so much on their cars with similar results at far greater cost. With a base this good I still have more to do like intake, exhaust manifold and removing the cat.......yep had the cat in place all this time, contrary to popular belief it was never a hinderance.

The early dyno figures were backed by three other dynos. I've had no issues at all fuel related in 18 months, and this car is full time E85. The motor, in my opinion, got better after the initial months of usage.

I think Evo's and their fuel related components fair very well with E85. This might not apply to all vehicles.

[10sec_rx7]

e85 is great stuff! nice and cheap and with the right combos can make big power!

[JEVO]

Forgot to mention I have only ever used Rozelle E85 @ 99.7c/litre (gotta love that).

Kyle can you ask your mate about the 260l drum thing please (get me a contact?)

[lautray]

Dale, any results from N/A LS1's? Before & after gains? Will 42lb injectors & a Walbro work?

[god084]

If a gain of 45 awkw can be had from E85, fuel pump and injectors thats very impressive! I asked about this a while back and was told if the car wasn't huge hp it wouldn't be worth it. Looks like this has been disproven. Will be good to see what advantages this can have for LS1's

[JEVO]

I'll try and post some dyno sheets

Stock LS1 respond well, but ones with higher comp and a good set of heads respond even better :)

last one i did was around 15rwkw gain over 98... that was stock cam and heads..

We have been running my wifes DC5 Tyre R on E85 when we had the engine rebuilt recently, and the fuel hasn't been any issue for us either. We planned ahead and upgraded the fuel pump and also installed 1000cc injectors to cope.

All up, we ended up with getting 194fwkw (Shootout mode) which isn't bad for a naturally aspirated 4cyl.

Its good news that Caltex will be starting to supply E85. It means we won't have to keep doing late night runs to the United at Roselle to fill up the jerry cans.

Does anyone know if the United at Roselle alters the ethanol mix based on the season like Caltex say they will do in the links that were posted? If they do, how does it affect those with specific tunes?

Ive had my car tuned on e85 by Martin, Made 284rwkw on his mainline through a unlocked 4500 convertor. 242rwkw on pump 98 fuel.

Its just a cam only VT with stock 853 heads, 228/230 cam, 42lb injectors @ 80% duty cycle and a walbro.

Ran 12.0 @ 118.6 mph at heathcote fullweight, 3.07 gears. Previous best with 98 fuel was 12.4 @110

Can't wait to see some of this stuff in WA, i wouldnt mind seeing what difference it could make to my Unopened LS1 :)

So the Walbro wasn't maxed out? Sounds promising. Granted, my setup is a bit more aggressive though. Great result at the track too. Well done.

[SIG-054]

The walbro still has some left in it, enough to do heads and possibly a bigger cam if i want.

[35R]

so i am officially "on the corn" or more correctly "on the cane" now

booyah!

[.charged.]

We run all our cars on the e85 with impressive results,,, except mine, looking at your system Levinracer,ok, well my thing had 365cc injectors on pump gas and they were at about 70% duty cycle. i put 550cc injectors in for the first run on E85 and they ended up being max duty at 5500rpm. i had done a bit of sniffing around some honda guys running similar engine configurations and they were running 1000cc injectors, so i bit the bullet and bought some 1000cc's and tuned it with them. these injectors are running at approx 60% on the E85, so in hindsight 800cc's probably would have been enough, but the 1000's are working well and the are very controllable at idle, so 1000cc's it is.
I may have to revisit inj sizing, Im running 550cc 2jz ones, with a VL turbo pump and haven't really had a good tune due on the dyno, when we originally ran the car for its E85 tune we had inadequate cooling fans, clutch slip and farked pinion in the diff on the day and a grumpy engine tuner due to these problems.
The Dyno sheet attached below, as you can see it made good HP down low and fell flat up high, we were blaming the above faults but it may of run out of inj. My tuner was having a dummie spit at the dyno due to the cooling fans it had were 2 house sized fans and the car kept getting hot, so he just did a safe tune for the car so I could run at Bathurst. We are going back to a mates dynapac dyno with a decent fan setup and think the 1000cc inj may be the go now especially since the other issues are fixed. My tuner was expecting around 130kw at 9000rpm after he tuned the car to about 6000rpm with decent HP, then it sort of fell flat as you can see and couldn't believe the final figure. It looks like I may be losing around 20kw due to maxed out inj duty cycle

Levin Racer were did you get the 1000cc inj from and are any mods needed to the fuel rail ?

This is what E85 can do (on the street, safely mind you, this morning) on very old 20" street rubber. I am pretty sure i was getting bad wheelspin, the thing was drifting sideways.

Of course what matters to me is circuit times, so we'll see [tomorrow]

Remember this is a 1700+kg car, with catback and mailorder e85 tune (yes it was checked on the dyno yesterday at mainline).

[Kyle]

Not bad at all!!! :D

One of the e85 dyno runs below, picked up about 45awkw..

Probably more hp to be had with a leaner a/f ratio as well Dunc, although with the punch its making now, why would you bother getting too aggressive.

Tommorow is going to be very interesting Dunc. I am gonna do a couple sessions on streets to get a reality check for Superlap.

Nice work on the power, now you have to win at Superlap don't let me beat you.

Looking forward to E85, I'll be converting as soon as it's available in the Penrith area, the smell and extra power is just awesome.

I think the essence of the story here Duncan is that the tuning requirement for a 150hp 1800cc atmo engine <> tuning requirement for a 700hp 3800cc twin turbo. What is ideal for one, isnt ideal for the other as Levinracer succinctly points out :)

1:40.1 from Duncan early in the day on E85 at the Eastern Creek supersprint. Shaved ~1 second from previous pb (pump 98). Can't argue with that.

there are i believe 3 locations in sydney that sell it. i have only bought it from Rozelle. i also believe, that either castrol or shell or both are going to make it avail from over 100 servo's in nsw sometime in the not too distant future due to negoiations with holden i think it was and them releasing E85 powered crumpledoors... i think...

i have also bought it through a race fuel supplier but found no advantage over the pump E85, just more expensive. mind you the race stuff did smell nicer out the tail pipe...

need to get my hands on some of this E85, but have a funny feeling that even fix/when shell and caltex get the deal together it wont be heading towards Nelson Bay :headbang:

This might me a silly questions, but what would happen if your car is tuned for E85 and you were out on the road about to run out of fuel and you could only get your hands on pump fuel?

[SIG-054]

Just get yourself another PCM with your petrol tune loaded on it :)

[god084]

You can do that?

[BlueTME]

I know this is not about E85, but a some guys on the EVO forum are playing with water/meth injection and are getting similar results to E85 without the hassle's of where to buy fuel.

[BLK 1T]

Ask Seldo
He probably remembers when you could buy an off the shelf water injection kit that fitted under the carby - back in the 50s/60s if I am right. Allegedly more power and better economy, substitute metho/methanol for the water for a better result.

brad,

i want to get more insight of your thoughts on the race e85 that the v8supercars uses. We are going to do back to back test this saturday on the dyno - pump e85 vs race e85. I believe that the race e85 has a control 108 octane level

Is your car naturally aspirated or forced induced? Did you get the car retune?

[10sec_rx7]

i did a nice high comp BA XR8 on E85 the other day.. a nice 35rwkw gain over the 98 pump...

we have just been using the pump stuff and have zero problems with the quality of it,

[levinracer]

mate, some people say there are gains to be made running the race e85 fuel. so far with the dyno testing i have done there is no difference between the two fuels. yes it has more octane, yes it is probably more reliable when it comes to consistancy in the fuel quality itself, but for the extra money i cant see the advantage in running it other than until caltex puts it at the pump in a greater number of locations, which is now going to happen.

i am also heading back to the dyno this month to do some more tuning/research and am buying a little more 'race e85' to try as well as pump e85...but so far i am not convinced.

caltex fuel will probably have a better control over quality with the e85 which will put alot of peoples minds at rest over this issue.

once i get the tuning done i will get back with some more information on what i have found.

let me know how you guys go.

brad

Now thats trick! So just to make sure I completely understand. I can fill up with E85 and flick the tune to suit. Do a track day ect whatever and then when I want to go back to 98 RON ULP I just run it as empty as possible then switch it back again and fill it up?

How much would this cost?

[Steve thomas]

Turbo Race engines using Race E85 have made Gains over Pump E85, Never seen any gain in NA engines but to be fair I have not yet built a Dedicated Ethanol NA Race engine but have built many Turbo versions.
Building a E85 L98 now so time will tell.

[Benson]

Ill update this thread once we get it retune on Saturday before Sunday's Round 7

[JEVO]

Evo 7-9 have a dual map option within the stock ecu. After almost 2 years on E85 I have dual mapped the car and now have an 98 map. The E85 map is now activated by holding the intercooler spray switch for a few seconds with ignition on reds. 98 has been set as the main map.

The reason for this post was not actually about the switch but the power now with 98 octane. Almost every evo 7-9 with exhaust, a/filt, boost control and tune will range from 170kwatw (e7), 180-200 (e8) and 190-210 (e8mr and e9). My car produced a whopping 230kwatw with mods as above.

How is this possible. When I first had the car (2 yrs ago) with mild mods it managed 205kw (98). The dyno used is widely regarded as a conservative dyno. Myself and the tuner were sceptical that their may have been some e85 in the tank when 98 was re filled. I have a wide band afr (number a re good) and have been through 2 tanks of 98, still feels great and more importantly feels like 230kw.

[taztassio]

apparently pump e85 is not guaranteed, in vic atleast. it can be e70 to e85, hence i would imagine a straight gain going from that to proper e85.

[Steve thomas]

Pump E85 is like that world wide. Also changes in winter

[sonic]

^ which is the reason i buy it from a race fuel supplier, costs $2.70 a litre which is almost 3 times the cost from the bowser, but a new engine would cost a lot more...

[10sec_rx7]

yep thats correct, its around $300 i think, shoot justin a email he is a good guy and will get back to you quickly

[Benson]

Ill update this thread once we get it retune on Saturday before Sunday's Round 7

We got the chance to do a back to back test between the pump vs the race e85. On pump e85, the car produced 238kw. We drained out all the pump e85 and poured in the race e85. First run without touching the tune, car made 255kw. We played around with the timing and produced 270kw with race e85.

So there you go, an extra 30kw from just the race E85. This is vary between different motors. Some might not make anything and some might make a few kw gain.

So i think it was well worth the extra $1.5/ litre over the pump stuff if your gaining 30kw's.

Note - Honda motor K24 (stock bottom end) Supercharged (10psi)

[dcoghlan]

We had a similar experience with the Fuel Control E85.

We had about 10 litres of the United E85 left over in the tank, and with thanks to Brett from Fuel Control, we added 30 Litres of the 108 Sucrogen E85, and our 4cyc N/A went from 193.7fwkw to 197.3fwkw with no tuning. Cant wait untill we have a full tank of the race stuff and get the tune touched up :)

Hey Benson, where do you get your Race E85 delivered to. We want to buy a 200 Litre drum, but they won't deliver it to a residental address.

We got the 200litre drum sent to our local workshop (bel garage)

Nectar of the gods.
We ran it at Pikes Peak with great effect. Our car arrives back shortly and we'll maintain using it, although we have a dual map setup.

We are waiting to see any adverse effects from it, so playing a cautious game, not taking anything for granted.

Nectar of the gods of speed. Our evo put our 227kw ATW on 98, went to E85 that jumped to 290, and then to 300, then to 320, we dialed it back to a more reliable level.

i got a txt from a mate on friday night saying that there is a Caltex in Hamilton Newcastle that sells E85 @ 94c per/lt not seen it myself, but he is not bad usally

I am another one considering switching to E85 for my H/C Monaro. I would be interested in the dual flash setup Dale mentioned. The car isnt a daily so the lack of outlets doesnt bother me. The results seem great!

Have thought about this also, but will need another fuel pump (external?) & bigger injectors to handle the extra fuel flow I think.

Yep, I may be looking at the same requirements as I am still running the stock gear and it must be getting close to being maxed out.

I'm currently running a Walbro in-tank pump & 42lb greentops... max IDC <70% now, but sure E85 will require bigger. I reckon the pump is already close to max output with current hp.

Let us know how you go Daniel :).

Bio E-Flex

A new choice in fuel has arrived: Caltex Bio E-Flex, a fuel that contains up to 85% ethanol blended with petrol. Bio E-Flex provides an energy option beyond the traditional fuel mix - something we can all feel good about.

The high renewable ethanol content in Bio E-Flex helps reduce greenhouse gas emissions and our reliance on traditional fossil fuels like petrol, so it's a better choice for the environment and Australia.

The ethanol in Bio E-Flex is made from sources such as waste starch from processing of wheat, molasses from sugar production and sorghum, which is grown for ethanol manufacture and low-grade stock feed. Ethanol is a renewable alternative to traditional fuels which are made from crude oil.

Plants which are used to produce ethanol absorb carbon dioxide from the atmosphere. When the ethanol component of Bio E-Flex is burned in engines, the carbon dioxide released goes into the atmosphere and is used by plants to grow. This "cycling" of carbon creates less build-up of carbon dioxide in the atmosphere than fossil fuels. The emission savings will depend on the plants used, ethanol production processes and freight.

The ethanol in Bio E-Flex helps reduce our dependence on fossil fuels, which improves Australia's energy security through a more diverse supply of transport fuels.

Bio E-Flex is specially formulated to meet your flex fuel car's requirements all year round. Different seasons can change the way fuel performs in your engine, so Caltex will adjust the blend of ethanol from 70 to 85% between seasons to ensure your engine performs correctly.

Bio E-Flex can only be used in flex fuel vehicles, so please consult your vehicle manufacturer if you're unsure about the correct fuel to use in your car.

Caltex seem to be on a good thing offering the E85 (flex) fuel, but their mix will vary throughout the year from 70% to 85% depending on what the climate is where this is offered, as E85 sometimes present a hard-to-start scenerio on cold mornings.

Given Caltex's 'flex' in their flex fuel, I can't see me using it in the race car (evo).

If they offered up a full-disclosure on the pumps as to what the mix is (like a lot of US states have to by law) then Id feel safer using it, ie; is the 15-30% mix 91 or 98 Octane etc (99% of it is 91, so you dont want a car tuned for E85 with 98 as the 15% mix then throwing an unknown identity in).

There is also a few other perimeters to consider with E85, and the info, at least here in OZ, isnt too forthcoming, sadly.

Like a few others I'll stick to a specialty supplier for my E85.

ive done back to backs with the drum, rozelle and caltex fuel and there is nothing in it, biggest difference was a few kw..

with both the holden and fords i just setup a X-Cal 3 flash box and the owners can swap between tunes when ever they want!

[JeffDoz]

We've just ordered E100, time for retune... ha ha. Nah, we mix our E85 ourselves. We get the drum of E100 and use a choice 98.

[sonic]

^^ Jeez a bit risky isn't it Jeff? You wouldn't want to stuff up the mixture! What ecu have you got in your car? Is it stock reflashed or aftermarket?

I pay Dasha $2.70 Litre for e85 racefuel, which is steep but nothing like the rediculous cost of ULP race fuel, but considering my car is used maybe a dozen times a year, it's only costing me, what maybe a few hundred $ a year extra than you'd be paying? it's worth it for the peace of mind i think. What are you paying for a drum of E100 and how many litres?

[JeffDoz]

We have the mix from the US boys, nothing overly drastic. We'll be fine. 200 litres of E100 is a good place to start!
