Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

[SS Laser]

its the same idea that red armstrong does to his xp pump but he epoxies his. still they dont flow as much as the aeromotive

How do you know? I linked a flow test that says it is very close. So I did more research and here I found that kenne bell says 1 volt at the pump is 10% so .5 volt is 5% ish.
The test I linked to is tested at 14 volts. The aero chart is 13.5. So I did the math:

The first figures are a modified 255 @ 14v, second row is 255 modified @ 13.5with my math, an third row is 340 aero trying to read there chart posted in this thread. The 340 looks like a walbro modified almost to a T!! Or a walbro with no pressure relief.

40psi @ 14v = 339 @ 13.5v = 322ish @13.5v = 340ish

50psi @ 14v= 331 @ 13.5v = 315ish @ 13.5v = 320ish

60 psi @ 14v= 309 @ 13.5v= 294ish @ 13.5v = 280ish

70psi @ 14v = 296 @ 13.5v = 281ish @ 13.5v = 260ish

80psi @ 14v= 277 @ 13.5v = 263ish @ 13.5v = 230ish

90psi @ 14v=259 @ 13.5 = 230ish @ 13.5v = 200ish

I want this to new pump to be the best. But I also don't want to buy a expensive walbro with no pressure relief. I hope this post is very wrong. But until someone flows one of these I am not sure. I really hope someone sends all 3 new pumps that have been talked about in this thread to kinsler to be flow tested. I would but I am poor.

heres a link to a post on the dw301

richard clark tested the dw301 and he doesnt play games when it comes to testing and being absolutely certain that the results are accurate

Thanks for the info on the DW301. Here is the GPH converted to LPH.
I did the math to convert to LPH I will add this to my other chart.

30psi:

12v = 69.8 GPH = 266 LPH

14v = 87.5 GPH = 330 LPH

16v = 97.5 GPH = 370 LPH

40psi:

12v = 61.5 GPH = 233 LPH

14v = 80 GPH = 303 LPH

16v = 91.8 GPH = 348 LPH

50psi:

12v = 57.3 GPH = 217 LPH

14v = 71.3 GPH = 270 LPH

16v = 85 GPH = 322 LPH

60psi:

12v = 49 GPH = 186 LPH

14v = 64.5 GPH = 245 LPH

16v = 72 GPH = 273 LPH

70psi:

12v = 42 GPH = 159 LPH

14v = 58 GPH = 220 LPH

16v = 72 GPH = 273 LPH

80psi:

12v = 35 GPH = 133 LPH

14v = 53 GPH = 201 LPH

16v = 66 GPH = 250 LPH

Sorry can't edit my first chart.
First 2 is modified 255, 3rd is aero 340, 4th & 5th DW301. I don't know if the DW 301 has a pressure relief?
40psi @ 14v = 339 @ 13.5v = 322ish @13.5v = 340ish @ 14v = 303 @ 13.5 = 288

50psi @ 14v= 331 @ 13.5v = 315ish @ 13.5v = 320ish @ 14v = 270 @ 13.5 = 257

60 psi @ 14v= 309 @ 13.5v= 294ish @ 13.5v = 280ish @ 14v = 245 @ 13.5 = 233

70psi @ 14v = 296 @ 13.5v = 281ish @ 13.5v = 260ish @14v = 220 @ 13.5 = 209

80psi @ 14v= 277 @ 13.5v = 263ish @ 13.5v = 230ish @ 14v = 201 @ 13.5 = 191

Here I go again. I think there is a some flow data on the Jay racing pump. I will look into that tomorrow. Here is more info to compare.

Here is AMS test on a non modified 255hp at 14v and my figures at 13.5v.

Then third is Aero's chart for 255hp again as I figured. That chart is hard to read.

Also 4th & 5th numbers are for the DW301. Again at 13.5v is my math figures.

40psi @ 14v= 290 @ 13.5v = 276ish @13.5v chart = 270ish @ 14v = 303 @ 13.5v = 288ish

60psi @14v = 260 @ 13.5v = 247ish @ 13.5v chart = 230ish @ 14v = 245 @ 13.5v = 233ish

70psi @14v = 231 @ 13.5v = 220ish @ 13.5v chart = 210ish @ 14v = 220 @ 13.5v = 209ish

80 psi @14v = 202 @ 13.5v = 192ish @ 13.5v chart = 190ish @ 14v = 201 @ 13.5v = 191ish

According to those figures, the dw is the worst flowing of the 3. However, it would he nice to see all 3 pumps tested by the same person using the same equipment.

Some more info for you guys. A bunch of DSM and EVO owners punch in the pressure relief valve of the walbro for more flow. Here is a test you might have seen before.

Here is the link you will have to copy it because I am not allowed to post links. add the http to the link guys. Sorry about this.
://forums.evolutionm.net/evo-engine-turbo-drivetrain/262346-ams-ultimate-fuel-pump-test-6.html]AMS Ultimate Fuel Pump Test - Page 6 - evolutionm.net This is a link.

Looking at the modified 255 it looks to flow about the same as this new pump when comparing the aero's 340 graph.

It sucks for me because I am running a modified 255 an needed a little more and I wanted this new pump to be the best idea. That is how I found this thread. Doing my homework on this new 340 pump.

Hope some of you guys get good results so I can buy this. Take care.

Depending on what your operating pressure is the Jayracing pro series 044 pump may be one to consider (it can be installed in-tank). It outflows the others at higher pressures.

If I am reading this correctly the data above shows a Walbro 255 flowing 276LPH at 13.5V @ 40PSI?

Yes but that is my figure of 5% of the flow at 14v in the AMS test. So it is what it is. All I know is a modified walblows work really well. But I need more pump. I can get away with a modified 255 and a BAP. But figured I would research these other pumps first.

i have never seen a walbro or a modified walbro flow at the rate you are saying just the deats and the aero. these are the only two pumps that i know of having flow pressure problems at idle meaning too high. my reds xp pump has never had that problem and also it doesnt flow that high. jays raceing doesnt sell walbro 255's they are a 280 lph from a twin turbo supra. hey i only live 15 miles from you. have we ever met? do you have a gn or ttype?

my bad they are walbros i didnt see that they werent studded pos and neg. but i still cant believe that they flow that much

I did not do the flow tests just compared the data I could find for everyone.

If you look at the tests. All the new pumps flow a bunch at low psi 30/40ish. That is why you guys are having return issues. Makes sense. I am not sure what kind of volts you guys see at idle. But the modified 255 does not flow quite as high as the new pumps at 13.5v so no return line issues.

Jay's racing has a bunch of new pumps also but I am not trying to read his charts and figure it out. I have more info to post in another post to not clutter this up.

No I don't think we know each other. But I would love to check your GN out!
I do not have a GN. I have a "93" Talon and old school "87" shelby dodge GLHS. But have always loved turbo Buicks!

More info next.

Here is the flow at 14v sent to me from aeromotive. So the first 14v is a 255 modified from the AMS test. Then my figures at 13.5v. Third row at 13.5v is me reading the aeromotive chart. And last is the new 14v for Aeromotive. I removed the DW301 from this list.

40psi @ 14v = 339 @ 13.5v = 322ish @13.5v = 340ish @ 14v = 370

50psi @ 14v= 331 @ 13.5v = 315ish @ 13.5v = 320ish @ 14v = 341

60 psi @ 14v= 309 @ 13.5v= 294ish @ 13.5v = 280ish @ 14v = 325

70psi @ 14v = 296 @ 13.5v = 281ish @ 13.5v = 260ish @ 14v = 295

80psi @ 14v= 277 @ 13.5v = 263ish @ 13.5v = 230ish @ 14v = 272

would someone that installed these pumps please report back on idle and wot results such as knock issues resolved and/or richer wb or o2 numbers at wot

 

[SS Laser]

Ok one more time and I am done for awhile. We are testing a few parts on the dyno soon so we are going to try the aeromotive. Was told buy a respected friend who I trust. That this is the pump to solve our issue for now.

I had also contacted aeromotive about what this pump will flow like with a BAP. This is what I was told.

With 17 volts flow at 60 PSI was 397 LPH and at 80 PSI it was 363 LPH.

Thanks for the space here guys. I will still be lurking around reading good threads like this one.

Take care!

how can I maintain 14 or 14.5 volts to the pump? dont they sell some kind of voltage boost, to the pump? I have my pump hot wired now.

Kenne Bell and MSD make fuel boost pump systems.:biggrin:The MSD requires a laptop and the KB does not
