what kind of fuel set ups do you guys run on your cars making upward of 600whp. Ive seen people sump the tanks and heard pros and cons. Im looking for something more affordable and more in the line of less modification like dual 255s or bosche or aeromotive fuel pumps. and also post pics of how you mounted them

from what i have seen, t1 is very impressed with the dual walbro setup.

thats the least invasive way to do it.

MagnaFuel ProTuner 625 is a great geardrive pump that is self priming (doesn't need a sump) and I believe it's rated @ 1500hp. I'm using one on my E85 powered hatch.

The magnafuels are beast pumps and have had very little to no issues failing. I personally am running an aeromotive a1000 with a sumped tank. What are the cons you have heard with using a sumped tank?

i have heard of the seals drying out and rotting away on those style pumps. dont know how common it is though.

a good idea for the OP would be to go with the dual walbro setup with some bigger feed/return lines. my car w/ 1600cc injectors made just under 700whp. . NOTE: this was on q16 gas. As for e-85, even with the upgraded lines and dual pumps, my car ran out of fuel just over 500whp.

Synopsis: dual pumps/upgraded lines is good for 700whp easily on race gas
you may need to sump that shat to make 700whp on any other gas

this is just based off my personal experience. every car varies
^that's my anti-flame clause

Im running dual bosch pumps now. Over all this seems to be the best fuel system ive had. If I had a daily driver I would probably run dual walbros intank.

here is mine....Weldon pump

Twin Bosch pump setup or Single Bosch setup. Comes with -10an line for feed, aeromotive 100micron filter. Complete setup made for civic and integra.
I will include the sumped tank at no cost, I just need your factory on in trade.

I'm a fan of dual 044's, I'm going to be running them on the new setup for next year in the T/S car.

I just put the Full-Blown kit in our K-Series car, really nice piece after I got a few different fittings from McMaster

You think that could have been from the tune or something.....We are making around 400whp( i will let you now for sure after this weekend)on 1000cc's and 1 pump on e85

it's always possible. judging from the data that we have recieved from my car, i would venture to say that the fullblown dual pump setup is good, but not a save-all from a sump system.

disordinate

Not to thread jack or anything, but I'v been trying to piece together my fuel system. I met a guy at a bar with an integra with a similiar set-up/power level of what i'm tryin to run and he said he found out all he needed in terms of lines/fittings on here. and im not having such luck. anyone know what lines/fittings and anything else that would be needed to do an external sump set-up with a single bosch pump.

dual bosch 044

The BEST fuel system for 700whp, guaranteed. Easiest, best driving, most reliable, and very easy to do.

An in tank walbro 255, a Bosch 044 inline, and 4 ID 1000cc saturated injectors. The car will idle like stock, make killer power because of the good atomization of the injectors, no fuel level issues like running a sump, no additional fuel lines to deal with, etc.

i agree with that guy ^^

very simple and has been proven to work

tony413

tony i dont run a sump and i have the option to run dual bosch 044 pumps

tony1

Congrats. How are you getting the fuel out of the tank? The pumps having to draw fuel up and out of the tank isn't all that great of a way to do things. A walbro in tank feeding a bosch inline is much simpler and better for 700whp. An intank walbro isn't going to suck up air sometimes.

I'm sure you have your setup all figured out though.

+1 for the route tony1 suggests... I have gone that route although I am not looking for 700 on gas.

255 inline mounted intank to a Bosch 044 with the ID1000's is my new fuel system for the season. Plan on using strictly e85 and q16

tony413

im doing it the same way ive been doing it for 8months with no issues, my set-up sits in the same location a walbro intake pump would

in the event that i do start having starvation issues im going to add a sump and extent the lines of my set-up and place the filter inside of the sump, i've thought of it and supra guys are currently using that idea as well.

But with that setup your pumps have to fight gravity to pull fuel up and out of your tank to where your pumps are located, and if you have to place your sock even deeper into a sump that just makes the pumps work that much harder.

In my experience with pumps (I use 3/4" to 1" & 2" through large 4" and 6" trash pumps at work) to get the most out of a pump you want the suction to be as level and short as possible with the intake of the pump or the flow is decreased and the pump has to work harder, its the same with diaphram and centrifugal pumps. By placing a "lifter pump" (walbro 255) in the equation with a single 044 you can get way more out of the 044 and it doesnt have to struggle to pull fuel and maintain pressure by itself, and its much easier for the average joe to assemble IMO than the setup you posted.

FST GSR 1

Someone explain:

A 255 Walbro is 255lph at "free flow",correct? A Bosch 044 is rated to "free flow" 300lph correct? I thought I read a 044 at 5 bar can flow 200lph max. If you have a booster pump (in tank) feeding a higher flowing pump x.x" from the pick up of the in tank pump, will the in tank pump in fact at some point restrict that 044 even more then increasing base pressure?

Or

What is the calculation for figuring out BSFC when running 2 different rated pumps in series like this? (Assume .5/.55 as a general factor)
