I'll try to clear up some confusion in this thread so bear with me.
And Josh, just because you had some bad luck with returnless systems doesn't mean they are ALL bad. I am running a returnless system right now and the car runs like stock!
I do agree that the return is the better of the two though.
That is not accurate. Aluminum is fine running E85. You will not have any issues running it.Hey all,
Been keeping up with the member's install of the 10:1 Aluminator longblock and some other builds as well that are going E85 and was kicking around the idea of prepping my car for being an alcoholic...so to speak. lol I know the typical facts like you need a lot more E85 to get the proper A/F mix and that you are to remove as much aluminum from the fuel system as possible as the E85 corrodes the aluminum after time.
I agree. :thumbsup:If you want to do it right the first time and have big plans for your motor go with a full return style fuel set up.
That would be all you would need.Lethal Performance SN95 Triple Pump Return Style System [LP-SN95TRIPLERETURN] : Lethal Performance, Performance parts for Ford Mustangs
What other than that would I need to complete my fuel system besides injectors?
I will have to correct you on that. At cruise the car will only use 10-15% more fuel. At WOT is when you will need about 25-30% more fuel.As you probably already know E85 burns at about 30% more volume than gas. So at any given power level you will have to have 30% more pumping power than if you were running gasoline.
It does burn cooler, but that's not 100% accurate. I have seen data that says it is 105.E85 octane is like 94 not 105. The reason you can tune it more aggressive is that it burns cooler.
I have seen different results than the one single post by "black2003cobra". I wouldn't read it as the bible. In the test that state that "Heywood gives (100%) ethanol as having a MON of 89 and a RON of 107." I have seen reports of ethanol's RON is 129 (116 MON, 122 AKI). So who is correct? I would fair to side with E85 being 105 Octane. I have even seen it posted on the pumps.That is very very misleading....
While it's RON, Research Octane Number is 104 its MON, Motor Octane Number is only like 95 or 96 in that area.
You won't have enough injector.Well I stand corrected. Most of that is gibberish to me but I got some useful info out of what I did understand. Lol i still really wanna do the swap. Now one question I have is if I went full tilt minus the injectors for my initial kb install and run that fuel system, would I have any issues?
That is 100% in the tune! The car will drive like stock if the tuner tunes it correctly.And what's with the idea that if you run too big of an injector that you'll have drivability issues? You don't always run around in boost. So running around when your just driving in traffic you should have drivability issues since the injectors are too big for not being in boost. Thoughts on that?
:rockon:Probably not. Lol but it's not only the cooler temps but the price compared to race or even pump gas that is the advantages. I think I'm going E85. Let's burn some corn people!!!
Yes. It will drive just like stock if tuned properly. (I have tuned several)Well right now I'm stockish so I'm sittin with my 39's but when I go E85 and twin screw I might as well go with the 80's and full fuel system so I only ever do that once and done. So with sub-450rwhp and E85 I'd be fine with 80lb injectors?
I agree. Return is a better mousetrap!I'm going return style I think. I dont wanna deal with upgrading everything needed for returnless. Plus I like what I'm seeing about getting a cleaner tune with the return style. Plus if the potential is there, I'd like to get more than 700rw with this setup. High compression, high boost, and high horsepower numbers is what I'm after with this setup.
80's will be just fine even at 400 RWHP if tuned correctly.I have run three different returnless systems and have spent tons and tons of money trying to stay true to the original Cobra design. My advice F@$K IT!! I have about 200 miles on my latest system and the car never runs. So go return style any time you can.
80s may be too big for 400rwhp but I will ask around.
