Gasoline vs E85 in the 2011 5.0

[RSKtakR]

Can anyone tell me the difference between the fuel system in the 2011 5.0 vs the fuel system in the new flex fuel F150 w/ the 5.0 in it, or any of the Ford vehicals that E85 can be run in. Im not so worried about the injectors, Im looking more for info along the lines of difference in actual fuel lines, O-rings, fuel pump differences, things that would corrode or get eaten up from the ethanol in the E85 over time... if any? When you just do a search online everyone (which isnt very credible I wouldnt think) seems to just say that the fuel systems in new cars CAN handle the ethanol simply because of the ethanol in gasoline. I would think that there is more then the reason of the ECU not being calibrated for it.. but what else if anything would make a difference?

From what I've read and been told it all comes down to the tuning and that's it.

thats what I thought as well.. but is there ANY difference between the rest of the fuel system (any o-rings, fuel lines etc) that is on the F-150 etc? I could goto the Ford service dept but I bet they wont be able to tell me either lol

They would probably look at you like your retarded for asking.
Call JJ at WMS he answered my questions and I will be getting a tune from him very shortly

Ya im sure they would.. lol

I thought the 5.0 used in the trucks was a lot different than the ones in our Mustangs.

its not the same 5.0... im more curious about the fuel system that is used on that motor. IF its in fact ANY different then the fuel lines, filter, pump, o-rings then what is on the 5.0 mustang.

I really, reeeally doubt there is any benefit on an NA setup.
All else being the same you make less power on E85, its real benefits come from having a higher detonation threshold which although theres probably some benefit to more agressie tuning with ~100 ocatne race fuel, E85 is effectively a bit higher than that, so I doubt it will help unless running nitrous or boost.

i have seen 453whp and 421.5tq w/ LT's, clutch, 4.10 gears, cai and the e85 tune on an all stock fuel system.. not on my car. before the E85 the car layed down 422whp

the only guy to call or ask on E85 is Andy @ Dynotune usa... He lives a few blocks from Ethanol plants.. He also does the TUNE for major companies as well..

Please give him a call or shoot him an email, as he is the only one I trust to do a proper tune..

Its hard to say how conclusive that is though, it may not have been aggressively tuned on petrol.

Its just speculation, but Im just not seeing it with the mild stock compression.

There might be a benefit with an NA setup if it is high compression. And remember, the new 5.0 is 11:1 compression.

 

[PBstallis]

the stock 5.0 has high enough compression and the vct to take advantage of this

The advantage of E85 is that with its higher detonation threshold you can run much more aggressive timing without knock and therefore make more power. This applies whether N/A or boosted. I'm interested to see the long term effects of some of the people who are running E85 already.

Yah... thats what I just said.

There is a point where advancing timing no longer increases power, with a mild CR like 11:1 that can often be achieved on pump gas.

Its a big leap from 93 to 120

Since when is 11:1 compression considered "mild"? Most production engines have compression ratios below 10.

This. been there, done that, more timing made nothing, so no need for anything but quality pump gas.
