DW400 vs Walbro "525"

[@ryancrisp6786]

I'm running dual DW300 pumps on E85 in my 800+hp CTS-V. Never had an issue.

[@pc7225]

how many years have you had it?

[@2slofouru]

The DW even draws less current all around, choice time. Emailed AStewart but it bounced back. Thankfully you posted this video.

They don't "make" pumps. They import them and scratch the brand/part number off and laser etch their logo on it.

Thanks for the good information, so many Walbro fanbois won't listen to logic. I appreciate the effort your company puts into making quality products.

[@WarhorseS197]

Its pretty much says, hey our $200 fuel pump performs like a $130 fuel pump....

[@TheChrisey]

lol DW fanboys won't listen to logic either apparently

[@mikespl4180]

I see test voltage is 13.5v which is low, can we see a test @ 14.8v alternator charging voltage, or a bap voltage of 15.5-16.0v?, Applied to these pumps, as with adding voltage, current consumption comes down, and I hear walbro needs atleast 14.8v to shine. Not Knocking the dw400 it's a nice pump, but I think testing condition s could have yielded different results in a higher voltage setting, at straight battery power of 12.5-12.6v the dw400 probably walks all over the 525 walbro, due too less voltage with higher current draw.

[@glhomni]

It doesn't matter what voltage you compare them at as long as it is the same. The flow is almost linear when it comes to voltage so the difference between the pumps would be the same.

[@27ubs]

I would rather see data from an endurance test. A flow test to measure max flow will tell you nothing about the quality of the pumps.

[@maximusvonce1381]

Hey when swapping fuels, how long would you have to run the DW400 pumps dry before you damaged them. As i swap fuel the flow starts to slow down as tanks near empty. Is that ok on the pumps to drain fuel tank dry to get all the fuel out before swapping to other type of fuel. Just don't wanna burn my pumps.

[@nesmio7378]

Could you go through your test bench setup?

[@stevematecka9128]

why use two different power sources?

[@deatschwerks]

The pumps have different connectors, it allowed us to swap pumps in a single take.

[@fasnuf]

What ever happened to the Gen 5 Camaro drop in dual fuel pump? Last I heard it went back for re-engineering and now nothing.

[@deatschwerks]

The new improved version is on its way, watch for our announcement in the coming months.

[@BEYTEK]

So is your dw400 similar to a br540?

[@deatschwerks]

The BR540 is not a DW pump and we have not tested one ourselves so we cannot provide anything in the way of performance data. Some things that set the DW400 apart are its integrated check valve, application specific fitment kits, technical product support, and a 3-year warranty.

[@BEYTEK]

@@deatschwerks Great video fo sure. im now a the limit of my pump so ill be looking for a second pump soon. are you guys thinking of mechanical pumps at all?

MAK Performance used a JMS Boost a Pump on their DW400 on a procharged 2018 mustang. Held to 850whp on E85. They used it to hold voltage steady throughout the powerband. www.mustang6g.com/forums/threads/new-product-release-1000hp-drop-in-fuel-pump-upgrade.99826/

[@LowFlyinOK]

Hey Ivan, yes, we have. Send [e-mail] a message and we'll get a copy of the flow report sent over to you.

[@pc7225]

try vs Bosch 044 !

[@sssmithVR]

Who is running 50lb. of boost with only 1 fuel pump? Standard fuel pressure about 40 then add 1lb. fuel pressure for every lb. of boost. So at 70psi fuel pressure you would be around about 30lb of boost and thats a lot of boost for most people.

[@sssmithVR]

@El buckeye No doubt. I had 36lb. of boost on my civic making 713hp. But who runs 50lb of boost with a single fuel pump? Everyone I know run dual or triple fuel pumps once you get to those numbers.

[@sssmithVR]

@El buckeye at 36lb. I had a 10 gallon fuel cell E85 ran an external aromotive a1000 with Id2000cc injectors. But that was all we could do. Im currently building a CR-V to 500-600 hp. With a single in tank Walbro Hellcat 525. I'm boarder line going to a dual setup. Good luck on you build. 👍Race it, break it, fix it, repeat!

[@sssmithVR]

@El buckeye Nope. No intank pump at all. just the one external. Idk if it was the filter or the pump that held us back but 713 is where we ran out of fuel. so that makes sense on E85 at least. If we ran Q16 with meth injection im sure we could have hit much higher numbers. Or a dual pump setup but I thought that was plenty for a civic anyways. I was getting scared of the motor blowing up at that point because I didn't know how well it was built Unfortunately it croaked shortly after that due to the Darton MID sleeves. Still the most fun in a car I have had. I owned a 40 hot rod with over 1000hp and wasn't as much fun as the civic. cost a 1/5 of of the chevy too.

@@deatschwerks I have a DW400 with a BAP and the car runs good but I notice that at high RPMs high load/boost my FLP actually does decrease to around 40-50 PSI , would that make the walboro better in my case?

@@a.wheeler7731 Without knowing the specifics of your application and vehicle's set up it is tough to answer your questions. We'd love to help you resolve your issue. Email us at [e-mail] to discuss further.

[@superboogen]

with a fpr with a 1:1 ratio 100 PSI would be roughly 60 POUNDS OF BOOST ! I May be mistaken but what, ive seen data logging on true 1:1 ratio fpr's is there is a bout a extra pound of pressure per boost psi, so hmm as soon as i get to 50 or more psi ill consider Deatschwerks. highest I got on my twin walbro set up was 45 psi and they did well price to product wise. Deatschwerks seem to work well and are consistent not as dramatic of a loss.

[@glhomni]

Some manufacturers use 55psi as their base fuel pressure. Those applications I have seen them running upwards of 40lb of boost. So yeah, you want to know what it flows at 100psi so you don't lose flow and run lean.

[@superboogen]

@@glhomni ironic because I just finished u ppl a turbo ls build 1st ever. OEM pressure is 58 psi! I thought that was a typo but it's not. so yeah I'm dialed in at 58 psi....and plan to run 15 to 20 pounds 30 eventually once a trans that can handle power goes behind the engine.

Theres a aeromotive brushless for up to 1800hp

[@TheChrisey]

Brushless could make up for better performance too, since if you have extra circuitry you might as well add a booster in there too and crank it up to 18-24V so you don't have to run as much current through the motor windings.

Depending on your horsepower and fuel type the DW400 will support approximately 750whp on E85 and 1000hp on pump gas without a BAP. The kit you would need is part number 9-403-1047.

They are well known for their shitty pressure valves. If you use them up to their higher rated pressure, they don't last. I'm not the only one killing them, and I'll never buy another one. Take a minute and think about how some places mod them before they sell them...

I had not heard of deatschwerks and was always lead to Walbro. I saw them in a few channels and came here. Given flow and engine whine, I am now a DW customer, good job gentlemen.

[@TheChrisey]

@@SuperPenishole Lol "SuperPenisHole". Sounds like an intelligent guy... Anyway. A fuelpump isn't meant to run on high pressures over a long period of time. If you run them at 58+ PSI at idle, don't be surprised when they fry. Not to mention how the fuel heats up anyway.

[@drjdmtuning4982]

So what I got from this is if you are running 50 psi or less and use a static fuel pressure regulator don’t buy our product. If you run 50 psi and or use a rising rate fuel pressure regulator buy our products.
