after speaking to geoff, he informed me that getting the fuel from csr was impossible as the big fuel companies have signed contracts for the next 6 months preventing anyone else purchasing e85, however they are not using it themselves... and the contracts are probably going to get renewed.

FARKING CARNTS!

aaargh! put new rims on the car and my guard roller broke before i got to the rears.... no point changing fuels while its scrubbing :)

got one here handy if you wanna grab it. give us a bell if you wanna drop past.

  • 1 month later...

update:

filled up with a tank of fueltown e85... which is supplied by powerplus (racefuel manufacturers)

the first thing you notice is the differing smell... its not as sweet as the CSR (united) blend, and smells a lot more "fuely"

we threw the car on the rollers and the AFR's were out by 1 (richer)

we tuned the car for the new blend, and ended up pulling out 10% fuel and 5 deg timing on the top end for the SAME power...

same dyno, same tuner, and pretty much identical ambient temps :)

i spoke to the guy that got fueltown onto 85 and he was saying that united rate their fuel at 104 ron, and powerplus call theirs 106! (the pump however says 104+ just to be on the safe side)

the differing smell is due to the fact that powerplus use wheatgrain ethanol, whereas CSR use sugarcane ethanol

both fuels are blended with 91 ron.

we did a comparison graph, with the CSR and the powerplus fuels, but i forgot to grab a copy...

next week when i'm back at status i'll grab them and upload them unless trent beats me to it :)

For the southland E85 Power is the same, but needs 10% less fuel and 5 degrees less timing to get said result. (red line represents first run with old e85 settings, too rich and too much timing)

im so glad you victorians get a choice of what e85 you can run... we don't even have it on pump :)

Still don't? Jebus... that's bad... :huh:

But then i live in the CBD basically here in Melb... as an example to get to Hoppers (where one of the servo's is) and back would see me using a 1/4 of a tank just to fill it up lol.

So whilst we have "choice", doesn't neccesarily make it instantly viable. A Sunday driver ye, anymore than that forget it IMO.

Friend of mine used to take two jerry cans with him just to 'justify' the trip even then there was one trip a month being done (car was only driven twice a week, not very far)

Hamish - given they only rate it 104+, various batches might change between 104-106 by the sound of that statement.

3 months the blend might die down a tad. At least the United seems to be extremely consistent... Fueltown might not perhaps.

Just something to consider.

Where is Fueltown btw?

So does anyone havee info when a few more of them will be stocking e85 ? reading this whole thread has really made me want to try it and also trent is a full retune needed to swap over to e85?

Id also be interested in what e85 could do with a stock turbo? any ideas Trent??? im running 13psi at the moment, so theres not really any room to increase boost i wouldnt imagine

Im in St kilda so fueltown isnt too far at all! and the car is only a weekender so it wouldnt be a hassle fueling up.

Im ASSUMING the injectors and stock turbo would be the main things holding me back? ive got an aftermarket fuel pump, which would be fine.

Would there be any worthwhile gains to be had???? if there is, ill be knocking on your door Trent!!!!

R31Nismoid dismissed me asking this question in another thread. Overall consensus of e85 fuel was that you seem to be able to get more power out of a particular sized turbo then what you should. Therefore its better to go on the smaller side for a particular power level.

Although R31Nismoid does have a point that a full retune is quite costly and there would be better ways to go to get more power (upgrade turbo).

As you said the problem will be the standard injectors as you need 25% more flow just to maintain your current power level.

And is it worth the risk of potentially ruining your turbo.

seraphyn_r33 - you would run out of injectors before you make any use of E85 on a stock turbo unfortunately.

So you would retune, and not make full use of E85 without fuel.

You should get around 230rwkw on a factory turbo with E85 @ a rough guess

    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position. 
    • You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
