ams top feed rail
aeromotive fpr
-8feed/-6 return
255 intank
surge/swirl pot
(2) 044 external
(1) fuel filter external
-6 to surge and external pumps
-8 to fuel rail.

think i can get away with only one 044 and id1000cc and make 600whp on that setup?

go double pumper 255's or 1 inline 044.
or get rid of both and run 1 Deatchwerkz or aeromotive intank 300+ pump

i have a DW intank and i have plently of headroom on my set up

[turbo2nr]

but from what i gather when runing a surge thank the 255 in tank becomes useless as it only feeds the surge, so your dependent on the in line pump(s) to get fuel to the rail. with that being said isnt the limit of a singe 044 around 600-700whp? so running 2 044 should be able to handle all the power i would ever want to make ? correct?

also i dont like the overdrive small pumps like aeromotive340 and other small framed pumps, they are prone to overheating and dropping fuel pressure.

surge tank i missed but is this for a road course car?
i you feel fine buying 3 pumps thats on you, but it isnt needed then you have to wire in all 3 etc. Im just telling you from personal experiance on 2 E85 set ups i have owned and currently my DW is working like a champ with fuel and there are tons of daily cars running 500 plus with this pump
single DW pump can support over 600
mine is only on 12 volts direct feeding -8 feed line to a -10 rail and 1680 injectors @43 psi FPR. if i add a boost a pump to see 14-16 volts i can push her more which is what i plan to do when i make more power

[240jake]

so what if im looking for a max of 350whp on e85 will my walbro 255 be sufficient, do you think 740cc injectors would do or should i bump up to 850 or 1000cc?

going with an enthalpy e85 tune after i get the supporting parts, thanks.

Depends on the engine... For your power goal, on a CA18 or SR20 i can say a walbro and 740cc are enough. If it is a KA-T i dont know.

I am currently getting 1000cc highZ on my CA, but it is so i get some headroom for future plans while keeping injector duty under 80%.

[240jake]

thanks, yeah this is on an s13 sr20, i havent picked up the larger injectors yet so ima go with some 850s for the leg room.

thats plently, on 1000cc's @410whp with 255 walbro i was only at 65% duty cycle

[smoked240]

Just converted my Rb25 to E85. My setup is.
Aem ems series 2
Aem Wideband
HKS fuel rail
Injector dynamics 1000cc injectors.
Aeromotive FPR
Walboro 255lph

Currently in the process of getting it to run perfect before I bring it to have it tuned this winter. Only problem is I had to downgrade my firmware on the AEM to get it running with a base map someone had.
I think I have it where I can drive it but it's by no means ready to rock.
So far from getting the AEM and learning what little I have already, I am impressed by it.

[rabbit05]

Need some help here, looking for 800hp on e85.

Have:
AEM EMS
Built/Stroked RB25
Precision 6765
Need???
2000cc injectors
Aeromotive eliminator
New Aeromotive fuel regulator
-? Feed/ -? Return
And I'd like to stay on the stock fuel tank.

2000cc at least..
I would suggest looking into a duel pump setup. You can use the stock fuel tank. I would look online for the duel pump tank assembly.. it was back on page 4 or 5.. Here you go. Powertune - By Brand - Products
I can't help much on fittings though man.. Haven't dealt with them enough yet.

Or just get a a1000 and never have any worries ever again

That's also not a bad idea.. Either one works fine.

[4x4le]

Use the stock tank to feed a surge tank. From there use whatever good pump setup you want.

[nieko]

Everyone keeps saying get an A1000 and all your worries will be solved. Has anyone ever researched these or had personal use? I've talked to quite a few people and they all say fuck that pump. It overheats and dies... you have to buy the pump speed regulator for another 300 bucks unless you are just turning it on, drag racing, then turning it back off.

Mohan blew up 2 last year at FD. I believe Dai blew one up the prior year.

Everyone seems to be running single or dual 044's now.

Correct me if I'm wrong.

[4x4le]

The aeromotive pumps i have personally seen do suck. The 340lph pump my last customer had couldnt handel itself at 20lbs of boost and got hot dropping down to 40 lbs of fuel pressure

[S@nt0s]

Get the detachwerkz 304 double pump it. I
A1000 works but not for that power. The we maxed it out of the 33psi 796whp
And for people who say they duck well we have had our A1000 on for over 5+ years and never had a issue. This g has like 300+ passes on it and like 10 dyno sessions

[turbo2nr]

Single 255 in tank to. Dual 044 in line to dual feed fuel rail..

Done and done..

800whp easy..

[S@nt0s]

3 pumps if you wanna waste cash no need double pump it and call it a day. My single dw pump fed my 1600's solid at 70% duty cycle zero drops in psi - 8 feed and return stock tank

As I said above... for a drag car, its fine. You turn the car on, drive to the line, drive for 12 seconds, hangout then turn the car off.

No time for the pump or fuel to overheat.

If it is going in a road race or drift car, they are sometimes on for very long periods of time. Fuel heats up, pump heats up, boom everything starts going to shit.

That's why people get the voltage/speed regulator and different methods of fuel cooling.

Ok so here is my other problem. The car will be driven often in a day. I've recently had to daily it for a week while my truck was down, will the dual 044 be good enough? I'm currently running dual walbros and want to get rid of them. Also do I need the surge tank, it's really just a straight line car. No cornering, or drifting as of yet. Thanks for all the help again everybody, just trying to get this thing straight before summer. And fuel cooler of some sort.

And thanks for the link.

Ok so... I have a fresh rb 25 cosworth head gasket arp studs blah blah. Any way you guys are going to hate but I have an areomotive 340 and 740cc injectors. Stock everything else. Is this enough to make 350-400 whp with on e85? Or should I just tune the bitch on pump gas and be happy

Hate? Lol I'm no pro but I think at that power level pump gas would be perfect. I was on 91 and around 500hp. Pump gas is way easier to come by for most of us. I'm on a race/pump mixture right now so I needed an alternative.

[slideslidegnarslide]

I honestly just wanted to switch so I could keep my tempuratures down. I said hate because of the aero motive pump. I see a lot of people don't like them in this thread

[smoked240]

Is there an E85 pump close by? if you have to drive 20+ miles for fuel, it's a waste. Expect your Mpg to go down quite a bit. I only drive mine 6 months out of the year and have a pump in town with E85, E30 and E15.

Car get's tuned on Jan 10th! Will post my dyno result's, Shooting for .5-.7bar. Then new turbo and tune in march and going to push 450hp!
Would wait till march to have it tuned but I figured if I don't happen to get the turbo due to money, I can drive my car and have some fun with it. If I get the turbo I'll just throw it on quick and give it a test run at stock boost and if it's good to go I'll just drive the 6 hours to have it retuned.

Had my car dyno tuned this weekend. 270hp and 213tq. 10lbs of boost and 11ish for Afr. Tuned without wideband since my wiring is messed on it. Not even at 50% duty cycle. Only thing holding me back is my turbo.

let me revive this a little..... what fuel lines are you all using? i need to replace my factory hard lines to either -10 braided or hard lines.... what brand hoses do you guys use? ive seen some with a special coating, does that really extend the life of lines? looking for imput....

(im running 2200cc injectors, and i need to run -10 supply and -8 return)

need and want are 2 different things, most braided lines are ok to use with E85, I ran the woven braided lines from jegs. stock hardlines are good for about 450 on e85 after that you will have fuel limits.

i know factory lines are out of the question.... i am more curious on if people are running braided lines front to back, or if theyre making their own hard lines, and just using braided at very front, and very back? and if they are using custon hard lines, are they aluminum or stainless?

i ran -8 feed/return from pump to rail and back

All braided lines? What brand/ type of lines did you use? Have you noticed any corrosion from the fuel on the lines?
