E85 N/A Fuel System Questions

[BIGONTS]

Hi,
I'm in the middle of a fox F-150 swap, 2011-2014 Gen 1. I would like to run NA on E85. It will have a 2018 Mustang intake, OPG's, Mustang intake cams, CAI and BBK long tubes. I've got a full fuel system with -8 & -6 lines with a Flextech 340LPH E85 compatible turbine fuel pump. My questions is what injectors to get and how much power NA will this pump support? Thanks

frpp lu47 should be more than enough on e85 for a FBO NA coyote. dont know on that pump but you can plug it into online calculators to see. i wouldn't go nuts on the injector size. better to keep the appropriate spray pattern and low PW response for street manors. size them for what you need and then a bit of headroom and call it quits. Also dont get no named crap that is saving a few bucks. The quality of the injector data will make or break the quality of your driving experience and the layout for the ford data is a bit unique.

lu47's puts my my18 IM, gt350 intake and catback gen 2 at 70%ish DC near 7500rpm last i checked on e85.

edit: what ECU are you going to be running this swap with? standalone or copperhead/tricore?

are you tuning or a tuner doing it for you? if your doing it and using hptuners there are a few tunes floating around with the lu47 data that is spot on.

Mostly likely a tuner, Lund. Thanks

Could just use the OEM F150 injectors. Just about everybody NA in the F150 community runs e85 stock, tuned and bolt-on. Those that don't run e85, don't have it around lol

Hmm maybe I’ll try that. What size are they? Thanks

I honestly have no idea lol. I just know everybody with F150s runs e85 stock (myself included) while mustang guys usually "need" LU47s per their tuners. For some reason 50 is a number that comes to mind though I can't say why and don't quote me on that number lol

Well the 11-14 5.0 F150 are flex fuel compatible so I wouldn't worry about injectors.

Stock are 34 lbs

You'll still want to switch to 47's if you're going to do e85.

 

[BIGONTS]

Thanks for the input. One more Q, what TB do you recommend? 90MM?

Is there a reason for this?

 

[Jordan @ Lethal]

You have to supply more E85 to produce same combustion as gasoline.

Honestly the stock one is more than adequate. But the 90mm isn't a bad option either though; that'll play well with your set up.
