E-85, stock pump (non-green);
Looks like the limit is about 220HP (flywheel, safe number).
Pretty sure I'm out of fuel with the cold weather.
As air flow increases, pressure drops. Commanded voltage and such is in line with what it should be. So I'm out of pump I feel.
But could also be the pump going. I'll have to pull it and see what it looks like ...

NO the "update pump" is NOT the same as the SVT pump , There is only 1 true SVT fuel pump and that is the Motorcraft GREEN top fuel pump there are other Ford part # that show SVT fuel pumps that are not GREEN top fuel pumps and they also do not put out what the origional GREEN top pump puts out in LPH
The stock 02-04 is the same as the "updated pump" and will do in the 280 +/- range with out a problem , with good working pump , clean sock and filter I have pushed them to 320-330 to the wheels
People need to keep in mind that the fuel pump it self isnt the big problem its the built in return fuel system in the fuel pump cannister that is the issue
And yes the SVT fuel pump GREEN top puts out a good bit more then the stock or "update" fuel pump does

50psi rail pressure, round abouts 230hp (at the FW) and I'm seeing ~48% DC from the fuel pump on E-85.
So that pretty much calms any thoughts I had that I might need a bigger pump. Stock will easily meet my goals.

The 'update' pump is the same as the SVT, which is what I have being my stocker took a dump. But I was in that 'recall' group.
IIRC it's '02.5+ that all have the same pump.
Just curious because I'm running about 85% DC by the looks of it.

|mlbbaseball||not that i'm aware of, most people just run a return style if ur getting towards 400 whp. i think roushturbozx3 did a dual walbro pump and made them fit in the stock canister, but i don't remember, ask him. he's pushing 600 whp|

|fordtech||What I meant was are there any other pumps that can be used on a returnless style that will outflow the svt pump.|

well, after return style, you shouldn[t need to go higher. after that, a custom setup will be required.
as for the pumps, i'm pretty sure they changed them between the 00-04 models. i do think that the 03-04's are all svt's, but the 02's and under are not. its hard to base hp on a fuel pump if running e85. you need more fuel/molecule of o2. so you need to flow more fuel. if john is running 173/151 whp/wtq right now, i'd say thats more than fine on the stock pump. i'm not into tuning, but if you wanna multiply ratio's, i beleive e85 is at what 10.7:1? and 93 octane is at 14.7/1 = 1.374 x more fuel. = 237 whp on 93. now, i honestly have no idea if my logic is correct. but it seems correct to me! lol
but you definitely need more fuel.
The stock pump is good for a bit more than that, but not too much, and once again, i think its a different pump if you have an earlier year.

Kinda curious myself. I'll be needing to know this.

|norcalfocus01||I know this horse has been beat to death, but some people believe the SVT fuel pump is rated higher than the Zetec. I don't, I sure they're the same damn thing. I would say that for any NA build that the stock fuel pump is going to be fine.|
