  1. I might go
  2. So can someone explain VPN and what you need to do to avoid being caught?
  3. Plenty of reports on the evo x forums of the issue coming up after a few weeks. Mine was just a minor issue of it sliglty blocked one injector after a year. But even then I could have lost whole my engine if I kept on driving it without noticing something was happening. My first sign was one of my spark plugs melting and subsequent ones fouling pretty quick
  4. Orings were fine. Can't remember if i head the pshhhh or not... I'm not sure if i even hear it on the new Evo.. Been on e85 a year and half. Didn't drive it that often, only weekends. And even sometimes could go weeks without a drive
  5. TL:DR Black goo is present in e85 and under a combination of circumstancs their powers combine to form captain goo
  6. Well this is what i found on an analysis from another forum. I made a thread in the forced induction section.
  7. My research tells me in something in the e85 fuel itself
  8. Well i think i found me answer http://www.evolutionm.net/forums/evo-engine-turbo-drivetrain/486458-3-tanks-e85-look-my-id2000-s-unreal-7.html
  9. I've done a search on SAU on this topic but there seems to be no conclusive answer on what causes the 'black gunk/goo' that some people have with running e85. This is what has happened to my car: Blocked injector with black gunk, and all inside the head of my engine. This caused me to loose compression in that one cylinder Flow tested the injector and it was less than the others. It was noticed that in the flow test on start up that there was no fuel coming on within the the first second or so Scrapping some of the stuff out of the head: It has a rubbery feel to it. Put it with Unleaded 98 and it verly slowly disolves when you rub it on your fingers. Dissolves even faster with brake cleaner. No signs of the stuff in my fuel filter. Now a search on the internet many people have this issue: http://codsm.org/forums/showthread.php?t=3965 Explanation by a chemist who analysed the stuff: uote:Alright, I finished my analysis of this stuff, and my finding is very unexpected. I think it will probably surprise everyone else as well. This doesn't appear to be forming because ethanol is "such a good solvent" but because ethanol is a poor solvent. I suppose it should have been obvious when others said that it "washes right off with gasoline". Why would something that ethanol is selectively dissolving wash off with gasoline? If this were something in rubber or from our fuel tanks, wouldn't that imply that gasoline would dissolve it even more readily than E85? Alright, so what is this stuff? It is a appears to be a very large petroleum based hydrocarbon, similar to Vaseline. There isn't a single hetero-atom in the molecule (ie, the entire molecule is comprised of hydrogens and carbons), but the molecule is very large. It is also completely aliphatic (ie, only single bonds in the structure - no double or triple bonds). Where did it come from? I can only think of two different sources it could be coming from. It is either something that is mixed in with the rubber hoses that is meant to dissolve away in the gasoline, or it is a trace impurity in the 15% gasoline that is in E85 that wasn't separated during the fractional distillation process. Because it is such a large molecule, it wouldn't be very soluble in ethanol and could easily crash out of solution at the injector. Quote:So, let me see if I can wrap my decidedly non-chemist brain around this: This "very large petroleum based hydrocarbon", or vlpbh , is able to be completely dissolved into gasoline, essentially becomes part of that fuel, and is burned up in combustion, never to be seen again except broken down as part of the exhaust gasses out the tailpipe. However, with ethanol, the vlpbh is more or less "dislodged" from the rubber or distilled petroleum, and is carried by the ethanol as a separate particulate of sorts, perhaps partially burning during combustion (that which makes Scotty's 2 cents: Another explanation: http://www.gtrlife.com/forums/topic/86794-extra-maintenance-required-for-flex-fuel-or-e85-gt-rs/ So a few people flush it out with fuel cleaners or running a tank of 98 once in a while. Im curious if anyone on SAU has looking into this issue, and what they found what causes it? Why do some cars have it and some cars don't? There are lots of guys running e85 who they believe dont have any issues?
  10. Blocked injector from e85 goo causing damage in engine. Valves i think
  11. Probably not, my engine isn't where its supposed to be atm Haha yeah hard about that! Nah dont doubt your power figures, just curious what its like up top if its still like your previous graph, kinda showing that you have a turbo restriction. But then again bigger turbo and youll have a million killer wasps which you probably dont want!
  12. Injectors tested this morning for flow: Injector 3 partially blocked Injectors cleaned: Flow back to normal: Engine head being looked at: Lots of black goo inside Put some of the goo in some 98 octane. it did start disolving, but not at any rapid rate:
  13. Good work, post up dyno graph? Is the engine still being 'choked' by the turbro?
  14. No idea yet Will find out the exact cause soon enough All this stuff goes over my head, I just drive cars don't know much else
  15. There is extensive talk on it on these forums: http://codsm.org/forums/showthread.php?t=3965 uote: Alright, I finished my analysis of this stuff, and my finding is very unexpected.

  16. Yeah going to get it flow test and cleaned Bosch EV 14 1000 Did a search on SAU and apparently other people have this issue:
  17. So minor update Spark plug in cylinder 3 after a few km's of driving: Compression test on cylinder 3. 150psi. Rest where about 180psi Pulled the head off. Did notice some black goo in the chambers. Not sure if concern yet Pulled the head apart: Something not quite right, one port looking brand new: Vacuum tested the ports: One port something funky going on: Pull out the injectors, black goo covering on of the injectors: Dat e85 life
  18. I've been using Bulk nutrients for years and have been happy with their products
  19. Sometimes its nice to have a protein drink that you enjoy the taste. if it comes to say an extra $10 a kilo that's only about 30cents a serving Or one less Medium sized Mcdonalds meal a month
  20. http://www.heraldsun.com.au/news/law-order/nurse-sues-fitness-trainers-after-tripping-over-tyre-during-bootcamp-session/story-fni0fee2-1227277007163
  21. Yeah agreed. Had the ON whey from a friend once, was quite nice
  22. What protein powders is everyone using? Looking to make a switch for some nicer/different tasting protein after years of on bulk nutrients. Bulk nutrients is about $30/kg for WPC (~80% protein) or $35/kg for WPI (~90% protein) Looking for something maybe similair value wise
  23. Yup, thats why I put in the P&I amount It just gives you the option to put in less or redraw more should you ever need too
  24. This is on my main residence Interest only and Principal and interest can be essentially the same. The only difference is that with IO you have the option of putting in less if you want. I always put in more than i have too, and I can draw it out if i ever needed to. It gives you the flexibility. You can always make payments of the 'Principal + Interest' each month on a IO loan
  25. FYI there is no GST exemption for first year business. What you may be implying is that you are not over the threshold yet, and therefore not required to register My 2cents of free tax advice Best to register when you do surpass the threshold otherwise there are late lodgment penalties and general interest charges and potential fines for negligence
