For those of us who daily drive on e85, it'd be a good idea to run a tank of 98 every couple months

http://forums.evolut...07-post130.html

Out of interest, I work for Caltex at the Lytton Refinery in Bris and have had lengthy debates on ethanol based fuels for some time now with the onsite chemists.

I am aware of E10 fouling fuel filters with particulates (especially in the early blends where sugar cane was sourced for processing in early build facilities and had high "micro strand" content), but I haven't heard of any negatives of running straight e85.

A lot of testing has been done between Caltex and Holden on this (about 4 years prior to e85 hitting the pump) so I'd be sceptical that this is an overseas issue and not a concern here in Aus. I'm not sure if other fuel distributers (BP, Shell, etc) are providing e85 at the pump, and if they are, I'd be more concerned that this supply is fully imported.

Caltex is bio-fuel, not really e85 as it varies throughout season and on average in the low e70s

United are only stations offering true pump e85

I've been daily driving on e85 for over a year without any issues, but there are reports of aussies having problems with blocked injectors

Not quite, you're half way there, and yes it is a form of bio-fuel (as is all nature based fuels including bio-diesels), and depending on the season we use Butane and other stimulators to boost the ethanol rating to ensure E85 is maintained. FYi, both BP and Caltex do the same for 98 PULP.

I'm not familiar with what United is supplying, but its certainly fully imported - and therefore you take a major risk as to the quality controls put in place by the importers prior to distribution to ensure you have a good product. Alarm bells are ringing for me straight away as when you consider it takes 6-8 weeks for an e85 shipment to arrive from India/Singapore/Vietnam - or even longer if further abroad, and the fact its probably about e60 when it hits our shores, there could be a number of issues with it aside from it losing density and a number of other key characteristics - which mind you, then United's suppliers then blend it with god knows what to boost it back to +/- e85 before you fill up....

IMO nothing beats home grown.

Im on my 8th 44 gallon drum of E85 from United (Rozelle Sydney) since switching from Sucrogen. The lowest ethonal percentage I have seen is 93 (I test every drum)

The car gets raped hard in all different forms of motorsport and it hasn't missed a beat with United.

The Caltex brew is consistantly all over the shop.

United's e85 ethanol is sourced from sucrogen, or CSR, so that's definitely home grown isn't it?

Only the petrol is from singapore.

Well blow me down, http://www.unitedpet....com.au/ethanol (sourced from DBRL Bio-refinery Ltd in Dalby, QLD)

Good to see us QLD'ers are good for something :) So the e85 is sorghum based (cereal grains + sugar cane).

Maybe the problems are stemming from the e85 cleaning out any residue in the fuel tank from previously using 98 RON and clogging fuel filters. Who knows. Either way there shouldn't be any concern about fouling from e85 by DBRL - they use current tech refining methods to create e85. I'll go have a chat with the chem lab today to get their spin.

That's cheap. Must be GTR tax on fuel too.

False economy more like it. 60ltrs of e85 won't go the distance of 60ltrs of 98 PULP - ends up the same $ / km in the end, but you spend more time at the bowser than 98 PULP :D...

Not quite

I get about 20-25% less distance on the daily commute but saving about 35-40% at the bowser + united throws in more power/torque and zero carbon emissions = still winning

The benefits of e85 are there, this ain't no wheeler dealers scenario

Have filled up at 4 different stations around me now over last month and all been just over a dollar

I think that one near you is price gouging on all the kids with mod'd cars up your way

guess my news is old news now then, because i remember that sucrogen used to supply united, then again, that was in 2009, i guess they've made enough off their e10 and government subsidies to acquire their own refinery. Btw, are you in the refinery business? Care too hook up a fellow forummer with a grad program space? I'm doing chemical engineering =x

Indeed I work for Caltex in projects (as a Civil Structural Project Manager) at the Lytton Refinery. Caltex certainly has a grad program (there's information on the Caltex au website), where are you located? I'm not sure if you're aware that Caltex Kurnell refinery will be closing in 2014 so I'd suggest if you're south of the QLD border, don't waste your time.

well, i'm actually in vic, but i'm willing to travel to anywhere, so location isn't really all that important

Hey Kev, I have a Zietronix analyser in my STi. Reads consistently 85 to 87% out of Rozelle united.

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.

      Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.
