New walbro 400lph pump

[JoeSupra]

Would 2 of these be good for 1000 rwhp on race gas /meth?

[Alec]

Any updates? Has anyone put one of these on a Supra yet? Looking to be using one for my build but would like to see some results first

[supra931]

do these pumps bleed off pressure after 75 psi like the regular 255's?

[arkitek]

Do these pumps drop straight in even? Ive heard of other cars such as evos have to slightly modify the holder to get them to fit as stated in the link.

[FUZION84]

Bl was suppose to be testing these units.

THMotorsports has them for $108. Is this authentic? I read on a different site that they cant sell them under $160 otherwise they're fake. Everywhere else its around $160. The part number checks out, its F 90000 262

Theres also a DSM running it on E85. Made 588 HP @ 35 psi. Heres the Video Link

"588 HP, 482 TQ. Tested out the new Walbro 400 LPH on Eddie's STM Built 98 GSX. We maxed this pump out at 35 psi on E85 and got great numbers out of a single pump! STM will release an install kit for the 2g shortly. But as for the bigger picture, this DSM will still take more fuel and more power. Stay Tuned."

I spoke with them on the phone and I was told they don't carry or have them in stock. I was told to contact Walbro directly and see if they can point me in the right direction. I figure it was too good to be true.

Mines been on e85 for a few months now, no issues. Local buddies 400 is on e98 no issues for about 5 months now

From my math my 044 and 400 parallel should support 1000+ on e98(on an Evo) up to atleast 85psi fuel pressure. I plan on running a touch lower base(40) and then ramp up to 85 under WOT

Hope this works out well. I plan to upgrade to this pump since it looks to be fairly drop-in.

Im interested to know around how much power can a single pump like this support on race fuel or pump gas. I know 255 are maxxed about 550whp.

[WrongWheelDrive]

These are e85 stats....Pump gas will make a lot more power!!

[Reid@SP]

I've heard once or twice that 044 pumps are not E85 compatible. Mine have been acting up a bit and I'm going to inspect them shortly. I was thinking about these new 400lph pumps but E85 is a must.

[WrongWheelDrive]

I have a wally 400/ Bosch 044 parallel only ever been ran on e85...no issues

[thrustn]

Just ordered two walbro 400 pumps. Plan to run them on e85 to make 800whp on a 6766 turbo.

[Reid@SP]

Added these to SPR

[RogueSupra]

Hmmm I dont know about these pumps yet... it just looks like there is not enough testing

[dee_rz]

I thought about one of these before pulling the trigger on a jay racing pro series 341 looks like a single pump that could hit 700whp from flow figs! Will let you know how I get on with that once I get mine tuned in about a month :-)

Shit Could I get a map with pump gas??

[Reid@SP]

I've run these for a little while now in my car since Texas. They are MUCH quieter than my Bosch 044 pumps were and are doing great so far. I haven't reached a power limit yet but I'm not a good subject to put them to the test just yet.

[SilverAWD]

Very interesting. Walbro's generally hold up fairly well. I trust their R&D.

[isifmobile]

Was reading another thread about fuel pumps and Alpha stated the most he had made with a single 044 is low 700s on gas which is roughly 500 on e85, however that charts says over 600. Are the numbers based solely on flow or dyno result and on what engine?

[BAD954BOI]

I understand that fuel levels can be raised and lowed for what ever reason but why isnt anyone putting all aspects under consideration like voltage powering the pumps??

[imindirocz28]

Wow dang did full race jack the price up on those! They only sell from walbro for abouy $110. Thats at a distributor price, and list is like $130.

[racegate]

I just want to chime in and see these pumps are the real deal. I installed two of these in my car, but only had one turned on. Today on a single pump I was able to do 830hp at 11.5AFR/30-31psi no problems on C16. Didn't even have to phase in my 2nd pump! These things flow a TON of fuel and are bad ass for sure. I will probably need the 2nd pump once I go for the 35-36psi tune up, but this kind of HP on a single pump is just incredible.

[slither]

Racegate. That's really impressive. My guess would be that after 85 flow drops quite a bit. For race gas/big inch-lowpsi scenarios that's not a problem. For the guys who run a high base fp on e-fuel, that could/would certainly be an issue
I would love to see what they would flow with a booster at higher press
