Havnt gone to get my tune yet but i'm running a Bocsh 044 fuel pump with the walbro 255 intank/ID 1000cc injectors/weldon FPR/ built motor&head/BEP S366.

Wondering what kind of power ppl are making and ET ppl are running with the 044 inline pump. Or anybody with similar set-up please chime in.

Thanks

 

I would have thought the injectors would be the weak link in that list of parts to high hp, the 044 on its own would be enough for 550hp plus

 

I would figure that the pump would be my limiting factor. The 2 things im not posative about are 1.My pump set-up 2. The S366

My goal is a 750hp car consistantly running low 10's with the potential to dip into the 9's.

What do you think??

 

Turbo will make that power.

Fuel supply should be fine, given no issues with voltage under load and supply line size is sufficient based on the fuel you are going to run.

Only thing on the edge with that combination would be the ID1000's for the power goal you are wanting, with upping the fuel pressure you will flow more from the injector yet sacrifice on flow from the fuel pumps; and with the walbro 255 in the mix you don't want to go much past 80 to 85 psi of total fuel pressure as you will blow the bypass on the pump.

Good info thanks

 

Yeah i'v seen this chart from T1 before it is great info (I plan on having T1 tune my car BTW). I just kind of want to hear from others who may have similar setups.

 

It also depends on what gas you are going to be using. With that exact same fuel setup. I made 700hp on e85 with that same turbo.

I'm sure with race gas it will be a little more.

Good luck! Keep us posted.

 

not to stray too far off topic, but was your 6765 ball bearing or not.

 

mine is non ball bearing.. i do want to try out a ball bearing one though...

 

Thanks I will! I plan on running Q16

 

we make 750-760 on that fuel set up pretty regularly. properly set up car can go 9's with 600-650hp.

 

I made 670 @90psi base on Q16. havent ran a time yet. Plan on it tomorrow.

 

I hope so...breaking into the 9's will be a good goal for me I think

 

NIce....let us know how you do tomorrow man...good luck!

 

If the 255 is just feeding the 044, he can crank the pressure up as high as he wants; the differential pressure between the two pumps stays around 10 psi (10 psi being the "load" on the 255). There was a thread about 044s making noise a while back, long story short- I ran a test on my friends car and posted the vid. in that thread. From 50 psi base to 90 psi base (rail) pressure, the differential pressure stayed right around 10 psi.

With the 255 / 044 combo. and ID1000s, you could run 50 psi base fuel pressure + 20 psi boost and not run out of "pump". Somewhere between 75 and 85 psi (base + boost total), the ID1000s would outflow the pump(s).

 

I have a similar fuel setup albiet not a B series, I am a sohc F22b1 motor with some winds on it from a billet 62mm. 255/ 044 inline/ weldon regulator/ ID1000's/ etc. 613whp / 514 wtrq with room left in it, Tony1 tuned... 112 gas for fuel.

Edit: 60psi base pressure btw.

 

Thanks for the info...anybody have the link to this video?

 

Good info. Not to thread jack, but what if two walbros were in the mix in stead of the 044.

I feel I should note - that is NOT me in the pic posted with the video! that's swappedturboegg

I have to presume you mean "in parallel" since there's no practical reason to plumb two walbros in series....

And in that case you just doubled the flow of a single 255. No increase in psi capability, just double the flow.

 

Thanks!

 

Hey guys what about id200 with 255/044 online stock line in dc2 shooting at least 680hp Built motor t72db turbo

 

The ID1000's will outflow the 255/044 combo, going to ID2000's won't get you anywhere without more pump.

 

Hi Guys,

Can you please clarify the above statement that running a setup of two walbro in series is not practical.

I thought that I saw a post where someone posted a graph with a setup running 2 walbro's in series making approximately 800 whp on a B series turbo setup.
