All Sorts of Higher-Flowing fuel pumps coming onto the market

[mlomker]

Would a pair of these provide high enough flow at higher fuel pressure

Absolutely. Every time I see fuel tests done (like the one a few months back by DSport), it is always the parallel Bosch 044 setup that blows everything else away. These pumps aren't quite as powerful as the 044 but close enough...certainly over 1k whp.

I thought the Jay racing pump outflowed a 044?

Either way, I'm just gonna do a DW and deal locally with MAP if there is any issues which there shouldn't be, I met the DW guys and they seem pretty cool as well.

Soooooo....it's nearing decision time and I'm looking at one of these three pumps. The flow data seems pretty similar on all of these, I'll likely be running 26-30psi on my X.

all around 300 at 60psi
and 275 at 70psi
base is ~40 and I'll run 26-30psi so in that 65-70psi fuel pressure range, right?
going up to 80psi though, the aeromotive kinda dies off and falls to 225, while the DW holds 250-255.

MAP has tested the DW300 with great results...has anyone else run any of these yet, or have any links to any more tests/stories?

Hrm, no real data to back it up but wonder what the truth to this is (in reference to the aeromotive):

For reference............this pump flows less than a modded Walbro, which use to be available only if you told us you were running E85 with our double pumper. It has been standard for the last few months. Just adding this so someone doesn't order it to replace a modded Walbro as they will end up with less flow.

Here is a rough overlay that was posted in that thread you posted comparing the DW and the Aeromotive

Would be nice if someone would make a chart for a modded walbro as well. Maybe if enough people bother Buschur he will test one. lol

None of the pictures of these new pumps show the top of the pump real well, but seeing as how they are in the same casing, would it be safe to assume they could also have the pressure relief mod done to them?

Do these eliminate the use of a boost-a-pump or would that still be required for the 634hp? someone metioned earlier?

Since I'm posting....

Guy at RS said he swapped a wally255 for the jay racing 340 and it made nearly no difference...this was not on the dyno when the swap occurred, but who knows. He also said it is nearly silent, which is kinda cool. End conclusion was that the pump wasn't getting enough voltage/amperage and needed to be rewired....might as well do a BAP at that point? IDK...

Also another guy with the jay racing pump, 1g dsm, said to make sure its rewired...

Not sure, but others have asked that too.

Not eliminate but perhaps put off when you'd need one. eg a stock 255 runs out of juice at 420whp @ db, but one of these could possibly support closer to 500whp. Put a BAP on one of these for extra crazy awesomeness I guess!

FWIW, I think 311Evo made ~490-500 @ DB with the modded Walbro before the BAP
