Ethanol in sump?? What have I missed :S

My catch can fills up in around 2000ks with an ethanol and water mix, it evaporates out of the oil so the ethanol must be running past the rings on cold start. (I assumed it would.) the water is just condensation.

DO NOT use Chrono V if you are running E85. The ester in the oil reacts with the fuel and will create a milky substance in your engine.

The Motul rep told me only use Synergie 6100.

I ran 300v for 6 months as a daily, there was no milky substance until I changed the thermostat for a low temp one, the ethanol/moisture has to boil out of the oil so 80 degrees is the lowest I would run.

Since then I have been on the Sougi S6000 which is also ester with no issue either, GW recommend Sougi for ethanol so I cant see that it would be much different for the 300v...

I have done 1 tank on E-Flex from caltex at nicholls. ABSOLUTELY loving how the car feels!!!

Gonna go back in for a dyno run this week.

This is only the "e70" according to the lady at the counter.

I am pretty shitted off at the pricing, first tank was 98.5c this tank today was 111.9c

the tank today was 23% cheaper than Vortex 98. THEY MUST NOT BE SERIOUS ABOUT GETTING THIS STUFF OUT THERE!!! as there is absolutely no way the price saving is enough to make economical for these new cars to run the stuff! and thats only on 70% ethanol. even less economical when they go 85%

But since I'm not in it for ecomony... Best power upgrade EVARRRRR :ermm::huh::no:

i got my car idling/free reving with safe AFR's yesterday afternoon in the driveway. cant do much more than that without any rego however.

i found i needed to increase my fuel map near 40% to get it to idle at anything near reasonable afr and it was idling super rich on 98 (it was ~15:1 but the injectors were dirty and once cleaned it went to around 11:1)

oh wow.

Mine idles and cruises sweet on at anything from 20% to 30% more. Must be a good closed loop thingy i got going on.

but WOT the AFR's are nice (still a tad rich sitting on 11 - 11.5) around 27% more.

ok i post this straight at guilt toy coz i know he has some understanding of my setup. Effy the siggy goes off the road in december for the finish off mods, body, diff final fuel system, head and turbo/exhaust.

As with so many others ive decided to run the E85 fuel given im about to change much of the setup anyway.

The setup now is 2.8L 4cyl, running the hypautectic pistons im satisfied it can push my engine a little further as it wont ping running e85 correctly. Safer anyway... My current pump is only the Bosch 070 pushing 550cc denso injectors. Im at 95% capacity due to pump but injectors are close also.

I would like to run Bosch 044 single pump with approx 880cc injectors but im wondering do i go for 1000 instead??? Will the single 044 pump be able to supply enough or do i need to consider a twin pump setup? Will the 1000cc injectors be prone to squirting at idle or is it simply safe when you pick good quality injectors??? So far no one has said anything ive seen about E85 being anything less than perfect at idle but it pays to ask.

Im currently running rubber lines throughout, bar the length of stock steel line on the car. what fuel lines should i upgrade to? 6mm braided rubber or something else???

Im sorry to ask mate on the skyline forum and all but sadly im not aware of anyone having done it to a sigma yet. Any advice you can give me would be awesome before i go off buying my fuel setup and installing the wrong things. :)

Went to Kambah Caltex on my lunch break to fill up and ask about e85 - the guy I spoke to appeared to be the manager or at least someone cluey...more or less he said no fking idea. They were supposed to have it, but he's heard jack shit from anyone even though the website mentions it. Apparently he's had a lot of calls about it too lol.

Anyone know of any more melb caltex places that actually have e85 now besdies the springvale one, all the ones ive checked have said to me that theyll only put them in when the service station gets renovated.

Pat, I'm a little concerned about my fuel consumption given it's a 98 tune lol....I really need that fking wideband now hey lol.

I doubt my e85 tune should be any different in economy to yours, if my driving style remains the same.

I think my economy has been so shit due to the way I've been driving (booooooooost) and the fact that I doubt it finds it's way OFF the cold start map to and from work at all. Water temp hits about 60 degrees by the time I park at work....only just.

What "economy" are people getting from their E85 setups?

Cruising around town not boosting i get around 21L/100km,

Sitting on 100km/hr around 17L/100km (Very surprised it gets this low....over 300km to a tank!!)

Thrashing around (legally) 37L+/100km

My first tank of E-Flex (which i believe is e70 at the moment) got around 14-15L/100Km (this had a dozen tuning runs but a highway trip aswell...)

on 98 my average economy is something around 11-12L/100Km (all depending on how i drive it of course)

Your economy is SHOCKING! look at changing your O2 sensor

yeah troy ya gotta do a "normal" driving tank, take it further and just chill out sometimes lol.

If your at cruise AFR's are right then you should see the same economy. But def get that wideband if ya gonna do E-Flex

techedge will set me back $478 or some shit after GST and freight tho :verymad:

then I gotta get it installed....fark knows where I'll get that done, unless I can somehow just replace my factory o2 sensor with the techedge and plug that into the v44.

    • Thanks Duncan! Yeah it's street use for me only. Maybe occasional track day. Any difference in noise when running with the two pumps? I would expect the lift pump to be more quiet than the main pump so hopefully not? And yes, unfortunately quite a big price difference to the simple hanger setup. Though I'm usually willing to trade money for better reliability and future-proofing. Buy once, cry once and all that. I'd be very happy to never have to deal with fuel pump / wiring issues again  
    • The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p
    • On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.
    • So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.
