dashturbo Donating Members 280 Member For: 16y 5m 10d Gender: Male Location: Watsonia Posted 19/02/10 04:35 AM Share Posted 19/02/10 04:35 AM (edited) Looks like the only research you have done is what so called experts are telling you. The benefits of E85 are only achieved with the tuning of the ECU, or vehicles produced with flex fuel capabilities IE: Some SAAB and Volvo.Ethanol burns colder not hotter, ethanol does not produce more carbon, it will infact clean carbon from your engine and clean the rust from your fuel system.E10 was mainly produced to lower the end user fuel cost when the oil price was sky rocketing a few years ago.Petrol companies still make a massive profit on it though.And I made 297rwkw@17psi on pump, then made 363rwkw@21psi on E85. Now making 390rwkw@25psi.That's right I listened to what the experts said. That Flex fuel cars can overcome the damage of running a vehicle designed for petrol on ethanol.Ethanol has more oxygen so it is possible that more power can be achieved without running more boost. But like I said it has a lower energy content, which means you may max out your injectors trying to keep up; its not just a tune that's required, to get the best from ethanol you need a much higher compression ratio. But from all the testing I have seen, more power has never been a by-product. It is theoretically possible though.E85 may burn cooler, I suppose. However the E20 burned hotter than unleaded. However Ethanol does act like a detergent gathering any gunk on the way to your fuel rail, it also collects water, creating rust.. I never heard of it removing it.E10 was never meant to make the fuel price cheaper, but cut carbon emissions and "reduce our dependence on foreign oil" making the price more stable. It is still now even with Billions in government grants more expensive to produce and sell than ULP (excluding the fact that ethanol is excise free (38.143 cents per litre on petrol and diesel).When we increase the price of food by using up supply in Australia, it reduces our exports to countries that have little food. Its not like you working hard for $50 instead of a Chinese person doing it for 5 cents, that is because for some reason their work is not considered equivalent to yours. Ironically because people don't like chinese because it might be from a sweatshop!anyway I'll shut up.. this soapbox looks fragile! Good luck with the runs Edited 19/02/10 04:36 AM by dashturbo Link to comment Share on other sites More sharing options...

And that's exactly why it works so well in boosted applications, any turbo or supercharged engine is effectively running way more comp than any n/a motor - most engines are still rated by their natural compression ratio, bt when you add positive pressure into te equation you have instantly increased your effective (or absolute) compression ratio by that of a ratio. Sorry, I can't think of the exact ratio - but if I remember correctly most falcons running 10 or 12psi are running around an 18:1 absolute comp ratio...

I guess I just didn't think fuel with less energy could make more power, even if the disadvantage of a petrol engine is overcome. I suppose a well done is in order. If it makes more power and that is all you want, then fine. I just hate the stuff, and everything it stands for. However you guys shouldn't have to hear me rant.. my apologies Link to comment Share on other sites More sharing options...

Personally I believe that there is no extra harvesting in our local market for the E85 as it is simply a larger mix of what is already there. There is one service station in all of NSW that sells it, and they only buy 10,000L at a time. The fuel is still only in its infancy here and as a result there are only a small amount of people and tuners using it. You do require a larger fuel system to get the same level of power though - if you maxed out a bosch 044 on 98 pump, you will need 2 pumps to reach the same power level. E85 is also hydroscopic, so it dos absorb water from the air and as a result can not be kept for a long time. This is also the reason why you get the surface rust on exhaust systems. The oil also needs to be changed at more regular intervals as it can go slightly milky.As an everyday fuel, no it is not ready for the mass market. However, for a weekend warrior/track car the benefits in a boosted application are fantastic considering the price - 99.7c at the pump in sydney.CheersPat Link to comment Share on other sites More sharing options...

F6R Member 81 Member For: 16y 2d Posted 22/02/10 05:27 PM Share Posted 22/02/10 05:27 PM There are many blends of E85 out there. They are not all the same.If anyone in WA wants CSR E85 then we stock it. We only carry ~400 litres at a time though. Link to comment Share on other sites More sharing options...

From 275 to 300rwkw.Only mods that I have is nizpro injectors, cobra springs,14psi boost and walbro pump.Stock intake and bog stock exhaust. Rides on 19'Fuel is 99.4/l at Fuelzone in Chelt. and they claim that they don't run dry, so supply is not an issue.Cheer's Edited 04/03/10 04:00 AM by qikin71 Link to comment Share on other sites More sharing options...

qikin71 Member 60 Member For: 15y 6m 2d Gender: Male Location: Melbourne Posted 04/03/10 10:14 AM Share Posted 04/03/10 10:14 AM are they nizpro 72lb injectors?Not sure. Previous onwner had done the mods. From what I believe these are laser drilled.Dyno tune has everthing working as it should. No issues.If you have easy access to E85, Hoppers or Chelt. I would recommend doing it if you are looking to gain more power cheaply ie dyno time only.I was hoping one day to have 300 at the treads and to get there I was going to have to do something with intake and exhaust. At this point they stay standard.Cheer's Link to comment Share on other sites More sharing options...
