400-500rwhp fuel pump options

[Jdmwhip]

Looking to make 4-500whp this year off a 6 banger. ID1000's and stock sized fuel lines. Looking toward a single walbro 400, bosch 040, or parallel in tank 255s. Incase you havent noticed id like to keep it all in tank if all possible. What are my best options for in tank pumps. What pumps are you guys using/making how much power on how much boost?

[KAT-PWR]

Walbro 255, 400hp

[brndck]

what fuel are you planning on? e85 will have totally different requirements than pump gas.

Just pump, 91 or 93.

Run a Walbro 255HP in tank that feeds to a surge tank, that feeds a Bosch 044.

Or just skip the surge tank.

Am I ok to run it on stock hardlines? Want to keep the setup as simple as possible

[hybrid_eg]

If you will run e85 i ran a single WALBRO, Part Number: F90000267, E85 FUEL PUMP.

Last week I made 610whp on 22psi on a single pump, E85 and ID1000's. I have two of these pumps in tank but the other one was not connected as I need to beef up the wiring...

[garagelu]

I am planning to run a Denso Supra TT fuel pump or Bosch pump. Anyone have experience with either one?

Are you using stock fuel lines? What engine?

[hybrid_eg]

Yes, all stock s13 lines from tank to engine.. from there its going into radium top feed rail. This is on an RB26 motor.

[RurouniMidnight]

Im running walbro 450 e85 pump with id1000s on SR. If you want to keep it in tank and simple id suggest that plus its cheap, goodluck.

How much power are you making? I'm thinking I'll run a walbro 400lph in tank, they sound solid

Do NOT use a Bosch 040.

Bosch 044
or
Dual walbro 255's

I am literally waiting for my fittings to come in the mail and my paycheck to purchase 3/8" fuel lines. After these come in I am going to try and compile and post a very detailed write up on installing a Bosch 044 in tank. It has been covered before, but not the greatest..

If you Google Bosch 044 flow comparison you'll come across a shootout where the 255, 040, 044, and a few others were compared. The reason I chose the 044 was its ability to hold its flow rate as psi increases better than all the competitors in the comparation..

If you have any questions as to parts necessary, or what have you, to make this simpler than shit, let me know. 5/16 Lines have been shown to support 400-500rwhp on Supras. And you can plumb it into the stock setup SUPER easily and cheaply. But for peace of mind, and room to grow, I am upgrading to 3/8" Lines for a few more bucks. Super easy.

The Supra pump and pretty much its entire system has been reported to support 400-500rwhp. After that those guys say add a pump or replace the stocker with a better one, upgrade to 3/8" fuel lines or run another 5/16 On top of the stock one.

Check out this flow chart I came across. Showing the 400lph flows quite a bit compared to others. I'm looking to make 450whp @ ~20ish psi. I'd much rather leave the stock 5/16 hardlines in place since I have quite ahead of me still and re bending and fitting up new lines sounds brutal. Once I decide to crack 550-650whp then i'll be looking into a swirl pot setup, but until then I really hope I don't have to fiddle around too much to make less than 500.

what chassis? s13 or s14?

I had a dual pump hanger made up for S13/180SX chassis's.

Oh ya where'd you get that setup

[Noobles]

I had them made up by an engineering company here.

Uses all -8AN feed and return, comes with internal adapters to -6AN, or you can run smaller if need be.

I have a kit here if you were still interested :)
Not sure if shipping would kill from AU to USA tho.

[Bleakley]

That's the exact shootout I was referring to. The 400 obviously flows A LOT! The only thing I didn't like was how sharply it kept dropping off as pressure increased. Like it was straining or something, unlike the Bosch.

As far as fitting 3/8" hardlines. It's not as bad as you think. I'll be using NiCopp lines from autozone which are way easier to bend than the steel lines. If you wanted to bang it all out in one shot, keep that in mind as it's a NICE way to go.

I personally think most of the swirl pot business is completely unnecessary. If you're shooting for 550-650, I can almost guarantee with 3/8 lines and a) two in tank pumps in parallel or b) one in tank pump feeding an external pump directly you'll have way more than enough headroom for 600-700+ hp..

[Noobles]

Few of the install pics -- no problems here with 450rwhp, I do not let the tank go below 1/4 though.

^That is too clean, i would definitely be interested in this for sure.

I can ship no worries at all :)

Can you make one that holds a single walbro 450lph pump with a -8an feed?

[Noobles]

Can you make one that holds a single walbro 450lph pump with a -8an feed?

I am pretty sure it will fit a Walbro 450lph pump, I will need to test one.
You can use it as a single pump or twin pump setup, you will just need to block off one of the feed ports.

If you want to run a -8an feed, the internal adapter would be removed and you can plumb a bulkhead -8an to 5/16 barb fitting off it.

I used bulkhead fittings as you will need to adapt from the fuel pumps to the outlet from the top of the hat.

[Noobles]

Shoot me a PM

I have sent you a PM bud :)

[derass]

Very nice part!! Is the level sender securely mounted?

[eye-5]

Not sure if anyone mentioned but make sure you are running the pump directly off the battery with a relay. The e85 pump is looking for 13v and I was only getting 10.5v with the stock wiring. With the relay right to the battery I was getting 13+ v.

That's a sweet hanger^ I really wanted to use the powerhouse racing fuel hat on my S14 but after weighing my options and my goals I ended up going a different route.

OP, there are tons of high flow drop in units available now, some are well beyond the capabilities of the tried and true Walbro 255 which is probably close to adequate. I would use one of the higher flow options that comes with an install kit, simply for the safety margin and ease.

As far as the mentions of swirl pots and surge tanks, that is generally more of a high-g fuel starvation solution, not a supply solution. However, it can be used in conjunction with a stock tank and lift pump allowing you to keep the convenient factory mounted and easily filled stock tank, but still supply consistent fuel for big power as it is needed.

Denso 1040 and Im selling one :)

Good to know. I'm steering away from the 255 considering it starts to top out right around the hp I'm shooting for. Really hoping I can go with a walbro 400 drop in and call it a day for now. Simplicity is my thing

[2muchboost]

I have used Bosch 044's with no problem at that HP. Its a proven pump on many setups but I know there are other options out there.

That fuel setup is nice Noobles....reminds me of the PHR and Dual Aeromotive 340 setup I sold not too long ago. Looks like they made you a nice piece there.

Yep sure is, that was my test unit - it has a separate bracket for the send to mounted directly onto :)

Around 420ish

[Drake_fist]

I use a bosch 044 on my rb25 its making 434whp with redline setup at 7,700 Rpms never had a fuel problem with injector dynamics 1,000cc and aermotive ratio fuel pressure regulator.

[japslapsilvia]

I've read issues with 044 and E85, could be just rumor.
In any case, Im Running a single DW 255 in tank on a custom hanger i made, to a 3 liter surge tank, then a DW 350 in line pump to the motor.
-8AN feed, to a "Y" to feed both sides of the fuel rail, -6AN return to the surge tank. using Sard FPR.

Not to Threadjack, but is the isolator really needed on the intank pump? my hanger uses a worm gear clamp to secure the pump, anyone know of any potential issues with doing this?

Dont mind the welds, they are ugly as fuck i know, but its secure.

UMS Tuning has been running e85 in their unlimited class redline time attack Evo with the same Bosch 044 pump for 7 or 8 years.
