Alright I'm pretty set on stepping up my power goal. Mostly because I wanna step up my track goals. But I have a few questions I haven't been able to answer through research. My original goal was 500+ish or whatever I could touch on pump gas. So I kept stock lines, stock filter with -6 to GE rail, ID1000s, Aeromotive fpr, stock return, single Walbro 400. BUT! My track goals have changed some. I thought long and hard and talked it over with myself and have decided I want to hit high 9s. The first limiting factor in my setup is rods. Running eagle H-beams with 3/8" bolts. Everything else is good to handle 700+. I hope. I know there's a lot to it more than power. Suspension setup, driver experience, ability of my pig to get outta the whole yadda yadda. I'm not looking to put down ridiculous numbers the first dyno session nor am I looking to be a driving prodigy my first track day. This I understand. Now that's outta the way, I have a simple fueling question. This car will be driven on the street and a semi daily mind you. I want to keep a stock tank so no fuel cell or sump. I plan to run E85 so this thing has to flow. If I can get away without an inline pump that'd be great. I'm looking into running dual walbro 400s, -8 feed -6 return utilizing stock feed line. I know of the stock tank baffle issue with dual 400s. Ima make em fit. But I'm curious to see how far, power wise, that can get me. Looking into running ID, grams, FIC, something 2000. Idc what it is really. Another question is, how is she gonna idle? I'm running pro1s so I know it won't be butter. But will it be a stable idle below 1500 with 2000cc injectors? Or will 1600s do the job as well? Any insight on my issue will be appreciated.

 

with the new technology a good set of 2000cc injectors you can get the car to idle like stock big injectors and poor idle is a thing of the past

 

Yay! Well there's one problem down. Thanks for the reply

 

im pretty sure dual 340's will get it done and be a lil easier to work with on the hanger. might wanna consider -8 feed and -6 return.

 

Ya that's what I said I was gonna run. -8 on the feed for sure. But for the -6 return ill use the stock feed line seeing as how they're pretty close to the same size. Or do you think I might as well just run braided -6 all the way fpr to tank? But you're saying dual 340s will supply enough fuel for sub 800hp utilizing E85?

 

700hp on E85?

Here's a couple options.

1.)
Full-Blown dual pump hanger
(2) 340lph fuel pumps
8AWG power feed to pumps
Big relay
8AN feed, 6AN return
ID2000's

2.)
(1) Walbro 416lph fuel pump (F90000267)
8AWG power feed to pump
Big relay
8AN feed, 6AN return
ID2000's

3.)
Sumped tank
(2) Bosch 044 pumps (parallel)
8AWG power feed to pumps
Big relay
8AN feed, 6AN return
ID2000's

 

I thought the Walbro maxed out at just under 600?

 

I can get away with 1 walbro 400 running braided line for 7-800whp on E85. Well hot diggity!! That certainly uncomplicates things. Now as for running -8 to the stock hanger do I just run a bulkhead fitting on top and rubber line to the pump itself? Do I need a special braided line? I read somewhere with certain lines the ethanol will deteriorate the rubber

 

Here's a car I tuned a while back with the second option I listed. OEM Hanger with 8AN bung welded to the stock outlet.



Stock K20A2 short block
ARP head studs
Prayoonto Stage 2 cams
SuperTech valvetrain
Xcessive intake manifold
Precision 6265
E85
26psi boost

 

The 2000s will drive like stock with nearly any (streetable camshafts) if tuned properly.

The 450 being available now, ROB have you tried these? Will this work with you #2 setup i imagine so.

I tuned a car last summer that started to lean with twin 255's at 650 whp and full blown hanger. Looking to upgrade.

 

what was the fuel pressure?

 

Just bought some EFI2000s. Now gotta figure out pump selection

 

D-Rob pretty much nailed it with 3 solutions. Rather than a sumped tank however, you can always do the Walbro 255LPH in tank to the dual Bosch 044 setup. The Walbro 416LPH is a monster when it comes to a single in tank for flow. As pressure increases it does fall off a decent amount though. I'm that guy that would still have a 60PSI base pressure so that's important to me.

 

Any issues with an in line pump daily driven?

 

or you could just buy my weldon and be done with it lol

 

I feel like the 2 044s will starve the intank 255 or vice versa... No?

 

I've been told that E85 will eat up the stock rubber lines at some point, and you'll have to use E85 rated line and fittings.

 

Any more input?

 

Anyone else care to spread some knowledge or insight to my fueling options?

 

Stage 3 is what I am running with an FCS 5 gallon tank. I am also on Skunk2 Pro1 and it idles good.

 

This is my fuel system setup.. Made 715@25psi but only on a small t3/61mm turbo. With a 6262 I would see 800 plus.. I also run ID2000's and Pro 1 cams and the cars idles just fine around 1200 RPM.

 

For anyone else reading this thread in a similar situation, Fuel Injector Clinic 2150cc injectors are a great choice for someone looking to support big power, up to 800 whp or more and still maintain nice idle and light throttle characteristics.

These injectors include Fuel Injector Clinic's Data Match Technology, an all new in-depth data sheet included with our high performance injector sets and includes the data your ECU is looking for.
Included in this impressive new data sheet are Dynamic Slope Flow Rate and Individual Injector Offset Values for each serialized injector, as well as an Injector Voltage Offset table that has been customized for your injector set so that your ECU can be calibrated precisely for your new injectors.

Walbro 450 intank for the e85 along with a bosch 044 on stock lines with 80 base just made 800whp on a civic sedan. upgrade the lines and ditch the banjo and it will probably do more.

Im running a Turbo-Elements 6 gallon fuel cell with magnafuel MP4303 pump and ID2000's with -8 feed and im making a touch over 800hp and still have fuel left running Ignite E98

 

That top options seems much more cost effective than a dual hanger setup'

 

How reliable would an 044 inline be on a daily driver? I'm tempted just to run a single walbro 400 with -8 feed to the rail and the 2000cc inj I picked up and see where it gets me. Then add anything if need be. Picked up 80ish% of the supporting mods to get me north of 600whp. Just need some minor things to finish it up. Suspension is complete, I think? Need axles, a bit of fab work, some good rubber and some time to work on the damn thing. I appreciate all the replies and insight
