98 vs E85 - is E85 viable?

[Alcotane]

I would be careful with adding 2 stroke as most common types are not compatible with alcohol fuels and can separate out meaning that at some point the engine could end up being fuelled with near pure 2 stroke oil.

Most castor and ester based 2 stroke oils are compatible so these would probably be the best option.

[pureadrenalin]

From my point of view, the biggest thing Alcotane could do is some testing on different hoses, and list some that are ok. I'm currently testing my braded hose, and I'm not impressed.
Worst thing is, most of it is all new hose, that I specified was being used with E85.
I now have a 200L drum of Alcotane E85 that I'm not willing to use.

I know a bunch of people that either use E85 (and are going to stop) or are ready to use it, but arn't till we can figure out what hoses are good, and what arn't.

[sergei]

if in doubt just use PTFE hose (although it is tad more expensive).

[Alcotane]

This was done a long time ago, the problem is that there is so much tech info that I have been meaning to release in one big hit that the Technical Information Guide is never really complete.

I have just uploaded the compatibility section of the Tech. Guide for you on the Alcotane server this is only the compatibility section as the whole guide is about 100 pages.

This does not break things down to specific hose brands, only material type so you will still need to research what material is used for the brands you are looking at but it should certainly help.

Oh and for those who are not aware Teflon is simply a brand name for PTFE. Once you have had a look at the guide you will see that sergei was completely correct in saying PTFE is the best option.

Alcotane, are you still going? We have been having difficulty getting hold of you and need fuel for this weekend coming and have hearing no one has managed to get hold of you for some time.

Alternatively, what other options are people aware of for getting E85 in or near Wellington?

[strx7]

if you get stuck ring Taupiri Autostore, I'm sure they could get some on some kind of courier so you get it before the weekend

[Lith]

Cheers man. A mate in Palmy picked up some Sucrogen E85 from someone there that imports it so all sorted now

[Lith]

To give an idea of how cool this stuff is, here is some footage from the car we were getting it for at Playday on track on Saturday just passed. It is a S14 Silvia with relatively basic track-friendly mods - include a completely stock internal SR20 running about 17-18psi and a flexi-fuel setup - means it can run on whatever ethanol percentage is in the tank, it was running about E61 in this clip: http://www.youtube.com/watch?v=b8TbZ-cDw3A#t=1m56s

Great clip, the car looks very nimble and carrys great corner speed Does it have an LSD? Prob my ears playing tricks on me but it sounded like it was spinning up one wheel a couple of times, but given its lap times, it was probably both lol

Looks like another car dropped its guts through the infield section...Nothing worse than that happening at a track day and losing heaps of track time while its cleaned up

Good spotting, it has a factory Nissan viscous LSD (which will open up under circumstances like that) and he was having a few issues with it. Also has OEM Nissan 4pot brakes which were not liking the repeated high speed stops very much. Not a hugely bling setup for something that dipped into the 1:17s on one of its first outings so plenty of potential for improvement The owner is a good smooth driver too, who knows Manfeild quite well. There is a video on his account of him chasing 2jayzgte and 60Cuba with his old Integra haha

Not sure what dumped its guts actually, but there seemed to be clean up evidence for quite a while - never noticed a huge hold up but I spent a lot of time in the pits.

From what I heard the spill was from Friday.

Not sure if Adrian has done this, but speaking to a mate a couple of weeks ago who has a 300rwkw S14. He was having similar issues with his brakes - put in some ducting and that helped them last longer.

He hasn't yet, he's actually bought a rear wing which he will be fitting and will be doing a front splitter and ducting to the front brakes before the GTR Elite track day which will all hopefully help out a bit.

Good to know that it helps

[Mr Ree]

I have watched that clip a few times of the integra chasing the whales, loved it

The silvia surely has huge potential if this is only the early stages of it. Once he gets the aero and diff sorted, its going to be under the 1.15s without a shadow of a doubt.

Adrian's upped his game good to see,driving was never an issue for that guy he was always fairly handy on that front.

[DexGT]

the oil was from the test day on friday , was a V8 bmw race car , very impressive amount of smoke , was pretty fast before that . the bike guys at the test day were less than impressed

Can't help but think the same, will be interesting to see how it goes - should at the very least get really close to 15s which is quite cool to see out of a car which hasn't had moonbeams spent on it.

That's impressive. Does the owner mind sharing details on the car? Also do you mind sharing info about the flexi fuel setup? Sounds interesting!

There was a recent small article in NZPC on it (about the flexfuel) so it isn't a huge secret thing.

General mods off the top of my head as raced that weekend are:

Stock S14 SR20DET
Power Enterprise PE1420 turbo
Stainless tubular exhaust manifold
MIDAS Porirua/Edhouse custom piping for intercooler, intake etc
Deatchwerks DW300 fuel pump
ID1000 injectors
Siemens Ethanol Content sensor
Link G4 Storm ECU
D2 Coilovers (this line is a victim of a filter apparently )
Adjustable camber and toe arms
R32 GTR brakes + Carbotech pads
Nissan Viscous LSD

The Siemens ethanol content sensor is used as an OEM thing in GM Flexfuel cars so a proven unit. Outputs a square wave using frequency and pulse width to put across fuel temperature and ethanol percentage which the G4 Link can process (it needs a pull up resistor to get the voltage right but that isn't a biggy) while other ECUs need a 3rd party device to convert the signal into a 0-5v analogue signal.

The Link allows you to set up custom ignition and fuel trim tables so you can use the ethanol content as an axis and set up the map to adjust from there

[~SlideWays~]

Cheers for that, sounds like such a simple setup.

I'm contemplating retuning my 4agte once its rebuilt. Currently tuned on 98 but ethanol looks really tempting.

[Lith]

The car was of course on fairly sticky tyres, and it has had a bunch of stuff pulled out of it to be lighter - but yeah quite a simple setup. Silvias are an awesome base for a track car though

Ethanol does make a huge difference though, baring in mind fuel consumption goes up something fierce too. Basically the car feels quick enough on straight pump gas (quicker than what most people would be used to probably), when it gets up to E20-E30 it starts feeling fairly intense, and once it gets past E60 it feels more like something that it is on a mission from God. At that level of ethanol its hard to wrap your head around the fact that it is a stock engine with a little turbo on it
