single, in tank fuel pump for 500+ rwhp

Don't want to run 2 fuel pumps? Don't want to mess around with an inline or external pump? I present to you, the walbro 385.
http://www.euroexportinc.com/store/a...fuel-pump.html
same size case as a 255, but flows 50% more

got these pictures from a friend on the local forum, those are NOT my fingernails, they're his gf's

385 liters per hour at what, 80 psi and 16 volts?

until I see some real-world test results with flow, pressure and voltage you'll excuse me if I remain a skeptic

Not to mention, I don't see anything about this pump anywhere on the interwebs other than the site the original poster posted. I want a flow chart!

Is it completely necessary to have 2 pumps to hit 500hp?

What's so wrong with just using a Bosch 044?

Nope. People should stop in the archives sometime, there's a lot of good info there:

https://www.rx7club.com/3rd-gen-archives-73/some-fuel-system-ramblings-578521/

My Apex'i BNR pump, wired direct to battery, is supporting over 500 rwhp. I've run the car as high as 22 psi on the street with no issues

I'd like to know the Walbro model this is (GSS whatever) to see if there are any manufacturer specs available

This is like the Ebay GT35R dual ball bearing turbo for $450 bucks.

I am sorry for the skepticism but there is a reason why these pumps are so much cheaper than a bosch or a denso supra. Take a denso F/P next to a Walbro F/P and you can visually see the quality difference.

Perhaps off topic, but where can I get an Apex'i BNR fuel pump? I have search for weeks trying to find it but I can't find any online distributor selling one


Thanks Rich!

no worries about the skepticism, I'm not even 100% sure on the thing yet, but like I said, a buddy of mine here in town ordered it for his dsm, so I guess we'll see how it works, he was running out of flow with the bosch inline and a walbro 255 in tank. Apparently quite a few dsm guys are running them and seeing some good results. I'll update this thread as I get info.

Walbro reliability and quality are suspect, I wouldn't roll the dice with my motor.

yeah if you buy the shitty ebay chinese knock-offs, I know plenty of people that trust walbros, it's the retards in the honda scene that buy the 40 dollar knock-offs on ebay that break that are constantly bitching about that.

Only single intake pump I am aware of that supports 500+rwhp is the Skyline Fuel pump. I have maxed a properly rewired supras at 450rwhp, and usually a single walbro a little past 400rwhp.

page 2 is the important stuff towards the bottom, we'll be getting a flow chart for these soon hopefully. Sounds like the pump was made for a supercharged chevy, they think its for the zr1, not totally sure about that...
