Hi
Ummm don't I remember a thread here (which I now cannot find) from about 2 years ago about a US 928 owner who tried E85 and it melted his tank and corroded his fuel lines ???
Personally I cannot see the point of it, by the time you have changed everything you would need to change ,you could get a lot more hp from other methods... and have a large chunk of money left...

The 2025 might be okay - this is the package:

I was speaking to the pump and FPR and maybe the controler - as this system will need to be so big I can't have it running full steam all the time.

As I suggested, the tank may be an issue. But probably not an immediate one. Personally, I have done alot of research on this, real time and on the "innernet" - and I am doing it for all the reasons I have stated and more. I don't have to "change over anything" nor do I have any fuel lines in the car at all. All new ones - I bent some before in aluminum, and now I am doing them in SS.
"Corroded fuel lines" - thats kind of conjecture - don't you think? The lines are anodized aluminum - I don't know what the coating is on the inside, but I know its there. All other pieces (fittings) are Cadmium plated - anti-corrosion.
The GAS in the E85 is at 15%. This adds lubricity, and cuts down greatly on the corrosion, which is caused by the fuel being conductive, and also being able to carry water.
Your "other methods" - if you are referring to NOS, which I know is the apple of your eye - we aren't talking about a power-adder - we are talking about using a fuel every day that aids greatly in reaching the potential already in the car.
Today, 91 octane (the most we can get in the west) - is 3.85 a a gallon. I know its 1000s of pounds a gallon there in the UK - no need to explain - but here, this is expensive. The E85 is just over 3 bucks a gallon. Nearly an entire dollar difference in price, and I can run 25psi safely.

Brett. I have stayed quiet about your process. I have said nothing negative.

I wasn't being negative about your efforts, as a one off its probably a good idea cost wise and performance wise as long as its a long term solution...
I am not against using strange or different fuels....don't forget I was in Top Fuel that uses Nitromethane and Methanol to gain power.....and I wont mention Nitrous as its not a fuel...lol
My point was....to do this to a normal 928 would not be sensible....if you have the sort of money needed for this (tank/lines/injector rails/injectors etc) then surely a supercharger would be a better bet for performance and if you are worried about cost.....don't own a 928 lol....UK fuel costs around 3 times what you pay and that huge V8 rumbling into life every morning puts a grin on my face on the way to work....and the fuel costs don't worry me

I am intrigued with E85 conversion for my supercharged GT. It could enable me to run much higher boost levels safely ...

I don't get you sometimes - your posts. And I married an English woman, so its not a culture thing. WTF are you talking about? Did you even read this thread? The boost is WHY I will be running E85. Its cheap race gas available at the pump. Its very safe, chemically, its cleaner, and it allows huge boost. In the western states, we are EXREMEMLY limited with our octane in pump gas. Superchargers cause the need for more octane. We can get it with E85. Its simple.
This idea about "big money" is weird. I personally have big HP goals, so I am spending alot on the pump and FPR, but everything else was relatively inexpensive. The Rails were 250, the coating will be around 100. The tank is 300 or less, and the coating maybe nearly 300. Injectors are not special - just bigger - for me.
When I run my S2000 on ethanol (I will do it a bit differently this time) I don't really do anything. But its a much newer car.

When you get 1000 RWHP out of just Nitrous on an otherwise stock 240 HP 4.5L OB and not completely destroy it then please comment all you like.
You are the last person i would expect to hear from on this subject......

Hi All
You obviously don't get what I am saying here...
For your 1 off system its fine...
BUT...
A lot of 928 owners read these threads who are NOT mechanics and do not understand the ins and outs of this...
Let me put my point simply...
If any 928 owner is considering sticking E85 into a STANDARD 928 fuel system...DONT!!!

Which is what you are doing.
Moving forward, here is a chart on latent heat of evaporization:

Almost as high as methanol. It feels cool on your skin because of this, and it takes the heat out of the air and ports.

DID YOU NOT READ THE TITLE OF THE THREAD! This is supposed to be a strictly factual thread on what is required, what modifications need to be made and what things need to be changed to safely carry and run E85 in a 928.

I forget what controller you said you are going to run. Maybe this is important or not, it depends on the controller. Make sure you don't run batch fire injection. If you try and fire 8 injectors that big at the same time the rail pressure drops dramatically. Sequential injection is the only way to go when you are running big injectors. It dramatically helps idle quality as well as on the top end.

If so this is a very good point as this would then require a new EFI system, and that would probably take away all consideration from me.

Pretty sure we have already outlined that E85 in a standard 928 fuel system is not a good idea....
If anyone wants to give that a try, then that's their decision and hopefully they will let the rest of us know what fails... (I hope no one does.... but...)
Whether or not to use E85 will have varying reasons for many people...
As a fuel to assist with tuning for monster HP boosted applications such as Brendan and Ryan are suggesting, to appear green, economics... whatever, that's more of a discussion for OT...
Personally I have been considering this conversion, preferably in a boosted application, (but I don't think my finances will allow this any time soon)... so I would like to try and incorporate onto a more or less stock, non-boosted engine with appropriate fuel system upgrades and preferably an increase in comp. ratio.
Note... I wouldn't be doing it purely for the HP...

600 hp from 5L should be ok. 1000 hp is a bit different though. Several guys on here have already proved 600 is reliable.
