map ef4 stock block and e85 tscompusa tuned
If you go back and re read through every post the only one losing their cool has been you. AMS has proven the DW flows more with a higher availability of juice. MAP has pushed a single rewired DW to 600 plus whp with liw 12 afr's. You just said the Wally safely maxes out at 520 but pushed your customers car to 550, hopefully at his request. If you admit the wally maxes out at 520 and can achieve 550 with to lean of afrs how can map push the dw into 600hp with mu ruchet afr's if the pumps are equal?
Its just a question. You dont always need to jumo diwn the throats of people whose questioning paints your thoughts and ideas into a different camp. Its a car forum and good discussion should be encouraged oposed to preaching as gospel when the data is perfectly sound.

the only test that i feel is 100% accurate on this forum is done by MrFred aka Mychailo. He is not an average forum user, and he has loads of experience on how to perform thorough testing and has extensive knowledge in evos in general. he is a hardcore tech guy. the only reason that test was performed by him was due to negative reviews already on the forum.. he just confirmed them pretty much.
Ive never tested either pump with a boost a pump so im not even going to question that.. but i feel it would be neck and neck even with a boost a pump based on how the 2 pumps perform as is out of the box non wired and rewired.. then when you punch the relief in the walbro you get another 10% more pump power give or take.
yes the walbro 255 maxes around 480-520 its in between there. every setup is different, but its always inbetween that range on a dynojet.
map definitely didn't do 600 on e85 with a single dw300 with a regular rewire.. they must of used a boost a pump. i assure you that.. and if anyone trys to claim that i can tell you thats a load of bs with 100% confidence based on mine and other reputable sources.
i have done 6 or so cars on this fuel pump and they started off with a walbro then switched to the dw unit and it performed worse then the walbro.. again im just telling you facts here. this is not with a bap.
David Buschur might have the flow data you're looking for.. he actually has someone that can test the pumps real time flow ability.. ask him how the aeromotive works.. that supposedly did good in ams test also.. that is even worse then the dw pump!
well you approached me with aggression from the start, so that's most likely where the attitude is coming from.. but we can put that aside now, since you seem to be being nicer now. if i offended you i apologize.

Post #475.
630whp dynojet with one DW300. 13.5 Volts at 45psi base pressure. A boost a pump from 16V to 20V would get you even more. I have yet to see a Walbro do this. I read all the way through mrfred's information. I remember him and r/ternie from the old honda-tech days when I was building 86mm NA B series motors when I lived out west in 15 years ago. Good ole Rocket Mototsports cams and RMF headers. Anyway, I digress.
Reading through mrfred's entire post not just the first set of data, he has concluded that on a solid rewire the DW300 and Aeromotive will overrun the stock FPR. The Walrbo does not. All of the negative reviews I have read of the DW300 and the Walbro are on the factory wiring or in a Evo X chasis. On a solid rewire or BAP in a 9 chasis everyone has gone riched and had more fuel to utilize. I get the negative hype and the desire to move to the Wally 400. I myself would like to move to the Wally400. But I have seen it myself. Rewired Wally 255 to a rewired DW300 and the AFR's and HP threshold improved dramatically.
I am a little disappointed at the direction this thread has gone. It went from some very nice results for the EF4 to an onslaught of posts about fuel pumps. Why is this discussion not being held there as some of us are really only interested in seeing the EF4 turbo shine?
6 cars atleast ive experienced when they went to dw300 it lost fuel and went lean.
the dsm must supply more voltage to the pump or something. i know the dsm has no relay or any of that stuff.. my dsm's used to squeal the walbro's hardcore on rewire.

i didnt research about the dw enough to know what its capable of once its fed with lots of voltage..
i just know what it did when customers dropped it in as is.

Yeah there is no worrys about a head right now. And even if I could stumble on one, it would be for the built motor. But like I said I know car needs fuel and trust me as soon as I can stumble onto some cash I'll let you know.
