Did some flow testing comparing OEM to DW300c....you might be surprised what the results are.

[Ecoboost_xsport]

In my efforts to flow test all the available options for the LPFP, I discovered something between the OEM and DW300c. I know I have another post documenting my flow testing process, but felt this one deserved it's own thread.

It honestly doesn't look like the DW300c flows any more than the OEM pump. WHHHHAAAAATTTTTT?!!!!

That's pretty attention grabbing, isn't it? Well, it isn't false, unfortunately. I will say though, that my testing process may not be the most scientific as I don't have a large sample size to test. So did I have a bad pump to start with? It's plausible...but not likely. Both pumps were 100% brand new, never before used. I'd venture to say that the pump itself is a great performer, but when installed into the stock module housing...it is so restricted that it's full potential is hampered.

The caveat to all this...the reason why I'd still support this mod? It's WAY more rock solid throughout the testing process. The OEM pump is pretty sketchy, while the DW300c stayed consistent throughout the test. That alone mitigates the tuning nightmare I imagine the OEM pump to be after seeing how it is so inconsistent. It also draws slightly less current than the OEM, helping to keep things calm and maybe even a little bit cooler.

Wanna see? Made a vid about it all. Full test results of all 4 pumps are on the way. I'm done with the testing, just putting the finishing touches on the charts and video. In the meantime...enjoy:

yes the stock pump can keep up to well over the stock motor and injectors too

I wouldn't really call that test "keeping up". But that really wasn't the objective of the test anyway. After actually running all these pumps through their paces, I don't think I'd trust the OEM pump to move water through my fish tank, much less on anybody's car that has performance in mind, simply for the inconsistent nature it flows.

But yes, by the looks of it, the DW300c doesn't FLOW any more than the OEM, it just does it better.

Interesting. Good stuff John.

John,
How much voltage can the pump get when it's installed in the vehicle? Is it possible to get more that what the battery and charging system can deliver? I'm guessing not more than 14-15 volts, but I'm not sure.

OEM won't feed it more than 14.8vdc at WOT. I stated that in the video as well as have it highlighted in red text on the charts.

But you can install a Boost-A-Pump and push the voltages up. The DW300c isn't meant to go past 18vdc, but other pumps can go as high as 24vdc.

I’ve always felt the weak link in the fueling system of our platform is the in-tank (or low pressure fuel pump – LPFP). This isn’t normally an issue with mild to semi-aggressive builds as the addition of a higher output HPFP and injectors along with an ethanol blend and maybe even some methanol...

Any idea how much current said pumps pull at 23-24V? Screw buying the boost a pump. I can throw a boost convert together in like ten-fifteen minutes. Gotta match that inductor tho
