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

This is crazy awesome! The good'ol walbro 255HP has always been good at making great power, especially with a BAP behind it, but being able to skip the BAP and just drop-in a new pump that can flow pretty big numbers (even on E85) is just awesome! This thread will have info on all of them, feel free to add, especially if you have first-hand experience with any of them (including deciding to pick one up!)

I've also heard that Buschur is going to make their own (I'm sure it will be someone else's re-labeled though):

Price for all of these is in the $150-200 range, will be interesting to see people start using these!

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

Pretty sure MAP said they were going to have something for sale similar to these soon as well.

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

When are they going to make some nice pumps for Direct injection. :(

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

Dang. I should have waited, lol.

Ok, back on topic!

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

haha, well done scheides. would read again.

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

MAP is selling the DW pumps, I believe they just made 624whp on a dsm with a single DW pump.

I'll be hopefully throwing one of these in my car before the season starts next year.

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

Nice. I'm still going to rock my dual wally setup. If I max it out, I may look at these. Would a pair of these provide high enough flow at higher fuel pressure to run some of these High-Z injectors at higher pressures to flow more? My injectors will probably be more my limit, but if I can find a simple way to run higher FP, then they should be able to support more.

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

We have tried the DW and its everything its cracked up to be, the aeromotives are not available(will start shipping next week) and we have not tried one out yet but I am sure we can them for something like $165ish. Either way the DW out performs at all fuel pressures vs the Aeromotive.

just my .02

Thanks

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

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.

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

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.

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

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?

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

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

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

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

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

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?

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

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

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

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...

Searching around

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

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!

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

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

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

Thanks scheides! Ill just keep my 255hp then and just get a boost-a-pump. Sincwe ill need it anyways:( Trying to save a few ya know

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

I thought about posting that, but it's not true. He made like 480-ish and everything was maxed. They realized the BAP wasn't on. Then he made like 515 or 520 with the BAP and unmodified BAP but it was at the limit. THen they modified the walbro and he has pleeeenty of fuel system left now and made 530whp.

The weird thing is he made 480-ish on a single pump...maybe it was because it was partially wired from the BAP? or the BAP was actually on the lower setting? Not sure. 311, please pipe in!

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

Just on the Walbro, unmodded, I made 480-ish.

with the unmodded walbro and the BAP connected (hehe) I made 515ish and was out of fuel. IIRC my afr was raising to mid-high 12's at redline

We we then modded the walbro and still had the BAP hooked up. Next pull it was oober rich (low 10's all the way accross. Maybe even hit a high 9). Shane tuned it up for a little more safe power, and that was all. I believe it was quite late in the night at this point, and he had other cars to get on the dyno yet. I don't have doubts that this set up could take me a decent chunk further. We'll find out this spring.

Oh, and I may be testing out a few of these new guys with and w/o the BAP. :)

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

IMO not only will it save you a little money, but it's a damn fine (uncomplicated) set up.

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

Ah, whoops, I thought you guys did it the other way around. (Modded Walbro, then hooked up BAP)

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

For any of these data points, we need to know which kind of fuel was used. 500whp on corn takes a lot more fuel than 500whp on gas.

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

We made 640whp I believe on Kyle's 1g with a rewire, E85 and Deatschwerks pump. We were so impressed we've got 75 on the way :)

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

All data points are E85. Gasoline is generally not an issue for running out of fuel pump (for a lot of us anyways).


Ok with a rewire....I think that is an important point on these new pumps to really get the rated flow out of them. Not sure how different/important it is on a 1G vs an evo8/9 or X but I guess we will find out. I'm wondering if in 311evo's case he had the pump basically 'rewired' but running at 13.5-14v and thus was able to get so much more out of a standard un-modded 255 than others have.

Either way I'm looking at these pumps as an alternative to doing a BAP ($300-ish) on the stock X fuel pump vs just dropping in a 255($170-ish w/ adapter) and worrying that if I switch to e85 I'll max it out instantly....one of these would be $250-300 to get into an X and hopefully flow enough out of the box for my needs...then if I ever actually put a bigger snail on, do a BAP with it and really start to push one of these higher-flowing new-gen pumps...but w/o the need/complication/cost for a double-pump setup.

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

$269.99 will be our retail price for our Evo X fuel pump install kit and the DW pump.

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

Nice.

So next question: MAP made 640whp on the DW300 on a 1G rewired...peak power was at ~6300rpm. Does it take more fuel pump flow (or injector for that matter) to make 640whp @ 8000rpm vs 6300rpm?

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

640whp is the same amount of airflow which requires the corresponding amount of fuel whether it's 3000rpm or 10k rpm. :cheer:

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

I don't know about Evo's yet, but on 1G's, rewiring the pump was one of the first five things you did.

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

Not true, not all engines share the same BSFC.

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

Please elaborate?

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

Shane has implied that it does but it seems like a complex calculation on a boosted car. Fuel pumps usually have worse performance at higher pressures and boost is often dropping in higher rpms. I don't like math. lol.

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

That might be true if you're talking large displacement NA versus small displacement turbo, but since we all have the latter, I'd say it's a safe assumption.

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

Just my .02

False statement baised in that graph?!

http://i6.photobucket.com/albums/y22...Comparison.jpg

The real fucking question is the modded wally still the best pump at 75psi?

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

75psi is weaksauce Nate, Its that 85-90psi range I'm worried about ;) J/K In any case DC clearly has some mis-information and likes to use my account to spread it all over the internetz. I don't know that I would trust an aeromotive backed test as the be all, end all though...

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

Aeromotive on left, Walbro on right. Apparently the polarity of the pins on the Aeromotive is backwards. Thread Below
