Interesting tests on fuel pumps.

[kevin2004]

So basicly when the turbo is at full spool and you need the fuel the most, all but the bosch 044 tanks. Also this thread had some interesting results. I was surprised that two pumps inline did better than two paralel.

Good times on that info pork.

I have the complete results form the entire fuel test compiled somewhere on this new HDD. I've posted most of these results before in various posts.

This test was at 12..0V also - the 044 really likes 14.4 V and is peerfectly stable in it's operation at that voltage also. (the #'s go up about 30LPH across the board on the 044 at 14.4V)

PArallel flow is for more Volume - as you split the feed lines you have a larger "in motion" volume of fuel at any given time. With a series or in line set up you have reduced the head losses on the first pump and basically your sling shotting fuel through the line to the rail. Placement of the second in line pump is key to maximizing the slingshot benefit.

We could wax all day about the +'s and -'s of each pump and set-up.

I have tons and tons of data on all types of fuel pumps. Weldon, Aeromotive, Summit House brand, Walboro, Bosch (040 and 044), Denso, and several OEM types.

What I have seen is each pump has a sweet spot for, Feed line size, voltage, and head pressure. I'll be putting the ghetto flow rig back together this spring and working through the same tests that AMS did on Nasioc, only I want to use the 190LPH, 255 NON-HP, 255 HP, Stocker, Stage 3, and a Bosch 040. I have all of these but a stage 3 fuel pump... they go fast in the FS section.

Great discussion here, I enjoyed the re-read.

We did a write up with some data and pics:

Glad to know that about the A1000 before I dropped $300+ on the pump. Does bosch have a bigger pump than the 044?

[WhyTry?]

does it say at what volts these are test at? some pumps like to be at different voltages

Man that 044 is a monster

We will be waiting for your write-up. Do you have a how to for the bosch pumps?

2 bosch 044s.

Test was at 12 volts, but the Bosch really shines at higher voltage like 14.4 as Nacho said.

It is a monster. I do have a how-to.

Bosh 044 in tank, to bosh 044 inline with pics.


Enjoy. Please keep questions about the 044 in tank mod in the 044 thread.

It doesn't bother me at all. You know 100Xs more about how this fuel stuff works than I do. Any info you want to add in any of my threads is more than welcome.

More for my own sanity...lol

I do not subscribe to any of these threads, I just use the Adv Search for my username and keep up on my infomation.

I like to make sure that at least the discussion at hand stays focused on the topic. Usually fuel, as I'm backgrounded in a "fluid driven" hobby thats not car related.

I watercool computers, have since we needed to make our own water blocks... I've played with maybe 400 or 500 different "pumps" and had to figure out the flow rates versus the surface area of the machined pins or gates in the 3 dementional copper block. In that I was looking to move units of heat from a location to a dispersion source. My cooling system in the SRT-4 is the BOMB. lol.

This information also happens to apply to other "pump" driven systems, and my testing rigs from the good old days are valid again! WOOT.

I plan on doing a series of tests again, this spring, on some of the smaller pumps. If that works, I'm going to steal the Weldon, and Aeromotive units off the race cars at the shop and do tests on them, myself. then I can have apples to apples results for my rig(s). validating my results in my control of the variables.

Jesus, I wrote a dissertation on pump dynamics....oh well welcome to I need to move fluid 101.

Sweet, one of these days I will hit you up for info on cooling as well. It stays very cool right now though with no pistons in it.

The A1000 isn't good for a daily driver either. I have customers complain about them. Aeromotive wants you to spend another $300+ on their pulse board system that is supposed to allow you to run the A1000 longer. The problem is that they will tell you that the A1000 is not meant for the street, even though their literature says differently when run with their pulse box.

[WhyTry?]

i remember reading something where the aeromotive pump jump nearly 40% output when volts were increased from 12 to 13.5 volts

[boots]

Can I get some info on that cooling setup? Also just to make sure, when you say run the pump parallel do you mean run a Y from the line and run the pumps seperate and then Y them back together?

I know the A1000's are loud, but do they last long if wired direct without the controller?
