Differnce Between United E85 And Drum E85?

[rednose]

Deka 80 lb have an incorrect spray pattern to suit our cars and may contribute to hard starting or idling issues on 98 and worse on E85

Mick, Spiro has tuned my car for E85, we have no idle issues using 80lbs dekas and car starts fine at 4am when it's 8-10 deg outside, is there something he is doing that others aren't or is it a case of they work just not as good?

This injector was not Spiros choice, I had them already and he said that they will be fine.

Some cars that are imported to countries like Brazil etc may have fuel systems capable of handling E85 although their australian tune would not be set up for it, I assume something like the focus etc would be exported to brazil?? so their fuel system may handle it better than a falcons???? It would stupid to have different fuel systems on a similar model, something Matt may be able to find out through his work

Plenty of people use the 80 lb injectors, without any apparant issues, we have tuned quite a few sets, but some people are not as fussy as others with what they will accept and some cars seem to respond a little differently. The spray pattern is suited more to a single valve engine, like an LS1 rather than a multivalve engine that we use, E85 is a little harder to ignite than 98 (which is why sometimes it can be blended differently for winter) a combination of E85 and an incorrect spray pattern may lead to harder starting.

Deka's are a cheap injector and vary in quality quite a bit which is why I think some 60's are better than others, the same applies to the 80's

Thanks Mick, I always value opinions and answers from people like yourself.

Have been using eflex for over 6 months now and will be doing a United tune soon so I will see how they go with the higher ethanol content.

thanks mate, Some people think I'm against E85, I'm not, but when a customer ask me about it, I feel it is my job to give the pro's and con's as I know them, some have seen this as me being negative and will go somewhere that will tell them good things, things they want to hear, with more feedback from people using it, like you will be doing, we will find out how the car's fuel system will handle it over a long period of time.

has anyone tried putting some fuel hose and steel fuel line in e85 in a sealed container for a period of time? when I used to drag my bike I ran it on 50/50 e85 and 98 and didnt have any obvious problems

theres a saab and another car that can run on 100% ethonal

its a surprise what power people get out of the stock fuel rail if you see how small the steel hoses are, you can also drop the voltage to the 044s to quiet them down a bit off boost.

I doubt anyone here has the time/patience to put some parts into E85 for maybe a year or more, but who knows, maybe somebody has

Ratter, you said previously that the ongoing use may cause damage and not ethanol sitting still as that just absorbs moisture. Therefore, parts emerged in ethanol for a year or so would not give you any concrete evidence as the fuel will loose its "corrosiveness" as the water content increases or is it the other way around? For a proper test simulating a car you would probably need to circulate the fuel past the parts (tank, pump, hoses, filter, rail, injectors, reg etc.) under pressure and replace it every couple of weeks.

That's way more effort.

I <3 Bananas im bored.

It was stated in one of the articles above that e85 corrodes welds pretty easily. What would happen to a surge tank after a long period of use. It would suck if it cracked spilling fuel everywhere.

Also, what is a surge tank made of? If stainless then it should hold up ok.

we have run up to 457rwkw out of a gtx3582r with a single 044 and id1000s

Just had the car up on a hoist and can confirm it is only running the 1 044 pump

[ratter]

many parts could be affected once the ethanol has been used, whether used for extended periods or just sitting in it.

Things like fuel pumps, could be corroded internally after E85 use, but then deteriorates even when going back to 98, thinks like rubber hoses could begin to swell/soften etc and may show with more use of the vehicle, who knows Ford may have made our systems E85 safe allowing for any export sales or Eflex tuning, but Ford seem to have concentrated on LPG, maybe Bunna could find out info for us.
