Wondering what I will be limited to, power wise, with a full blown dual walbro setup and RC1000's...

Mr. Parks I have a similar set-up as pictured here. I notice there are no filters pre-pumps. Is that needed? If not where do you recommend filtering the fuel? Do you just use one fuel filter after the pumps...and what micron? Thanks

MrParks

i always recommend a pre filter. the return size on this system is too small as well but for small hp applications would work just fine. however for this car didnt seem to have a problem making 600+ hp it works well.

i think filters before the pumps are more important then the ones after. if you are running a new system with new lines ect, the ss braided lines are really dirty inside. i recommend that you run the system looped with it running fuel through the entire system without running through the rail so that your pre filters can pick up all that junk before running it through the rail and injectors. then just clean out the filters before start up.

i got a question...

right now i have a twin walbro setup that i built myself (1 intank 255, 1 inline 255 ran parallel), -8 to the rail w/ 1680s ran on e85. the external 255 is ran through the top of my fuel canister, and down to the bottom of my fuel tank. it's metal ziptied to my canister, and a weight is put on the end of the line, so that the line doesnt sway around.

it works great for me, and no real complaints, except that around under a 1/4 tank i can sometimes hear the fuel line gurgle...so im assuming its picking up air at that point...i was going to add a pick-up filter to the end of the line, similar to that of a walbro intank filter, which im guessing would fix my pickup issues at under 1/4 tank..

but i kinda want to simplify the car, as its my DD/street warrior...was thinking about running an 044 intank, and running a boost-a-pump on it. would that flow enough volume for 700hp on e85?

Does anyone know if Trick Flow TFX 120 lbs injectors fit a Honda? Just saw how cheap they are, and Im looking into 1200cc injectors right now.

At 700 hp on E85 the engine may consume 490 lb./hr. I suggest you should have
an additional 15% flow capacity for the PRV to maintain good pressure.
490 x 1.15 = 564 lbs./hr. The 044 pump operating at 18 VDC and 70 psi or less
will flow the required 564 +. Set the Boost-A-Pump for 40-50% and you should
obtain 18 or more volts to the pump.

exactlyyyy what i was looking for. thank you very much for your response.

would feeding the 044 w/ a modded 255 (crushed relief valve so it flows 300lph@43psi) help at all, or better off just run the 044 solo?

0em_at_kfi

Just run the 044 solo with the proper plumbing, venting, and filtration.

Walbro pumps generally do not bypass any volume until they reach head pressures
of 70 psi+. A 255 liter per hour pump operating at 13.2 VDC will typically flow
300 liters per hour with a 2-6 psi head pressure.
Due to the fact that gasoline is virtually non compressible, pumping fuel into the 044
inlet will do very little to improve it's performance. The only time a significant improvement
might be realized is when the inlet side of the 044 has been restricted by too small of a
inlet plumbing or restrictive inlet filter. Esentially the 044 pump would need to be cavitating to see an improvement from being force fed.

just wanted to say, thank you for giving your time to respond..and not only respond, but provide useful information aside from a simple yes or no.

thanks!

When running the power to dual walbros. What is the best way. I'm buggybacking off of a Painless 8 circuit kit. That is fused for 2 pumps. But is the power wire a big enough gauge for this? Pretty sure it's 16. Maybe 14.

I got a complete dual Bosch fuel system for sale with rail and regulator also and a set of 1200's precision injectors for sale

No one can answer my question.....

how would too small of a return work any differently on a small HP vs. large HP motor? Generally you are going to be returning the largest amount of fuel at or near idle...

Once you actually start consuming fuel with the motor, you are going to be returning less and less fuel making more and more power...so if it works at 600 hp, it should work at 1000 hp too right?

16 isnt big enough i dont think...I would recommend 12 although 14 would probably work.

Thanks. I'll have to check into it.

Would the OE feed line be enough to use as the return? On a 700-800 hp application.

I am in the process of replacing all my stock fuel lines, etc...I have been running a walbro 255 in-tank pump, and stock tank, but my stock fuel tank is shot and needs to be replaced, I can get a brand new one for around $300 or I can get a fuel cell that mounts in the trunk from Summit for $162...is there anyway to use my walbro intank pump in an aftermarket fuel cell???

SynTeg

Anyone have experience with a Magnafuel 4301 pump. Is 700+whp possible with 2000cc's on E85?

harhoosh

I got a qestion,

My current fuel setup is: 5 gallons fuel cell in OEM location, -10 feed from cell to pre filter to A1000 pump, -10 feed to engine with -6 return line.
I max this fuel setup at 897 whp so I decide I will go with Weldon 2035. When I was searching for one I find 2345 pump for a steal and decide to jump on it.
My question is, is my retune -6 line will work with this pump or I have to upgrade? The problem is if I have to upgrade the retune line, I should change the regulator also since it has -6 ports.

Looking for experts feedback.

im sure the answer is on one of these pages.. but im just curious if its ok to use a aeromotive a1000 fuel pump on a street car? i heard from some people it gets too hot... but i read a write up on it and its says street/strip use . any opion helps thanks

i think you will be fine if you get the regulator, its a hit and miss it seems. my a1000 burned up after 2000 miles on my hatch. only pushing around 350hp. its loud, if you don't mind that.

V-SPEC 1

If you use the pump controller it should last you a lot longer than not using one. I'm using the eliminator pump with the controller and so far so good.

harhoosh

Any one?

-6 is technically on the small side for that pump, but will most likely be fine.

If you put it on and you can't get the base pressure down low enough, the regulator and/or return line is too small. That's the worst that will happen so i'd give it a shot before upgrading anything.
