    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    Well I just remembered this thread so I figured I would update it. Aeromotive pumped worked fine on E85 all season. Went 10.62@124 on a walbro 255 out of fuel. Then went 10.58 @ 136.9 with fuel and a aeromotive 340 on a 2g DSM. Had a ok year with a electrical gremlin givings us problems all...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    We had the same problem and the talon did not run/tune right. But we thought it was the way our DSM pump hanger needs the pump nipple to snap up into it with a o-ring and plastic adapter. It did not snap in as well as a Walbro. So for right now we are running a walbro. But we modified our...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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 =...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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.

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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 =...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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...

    Aeromotive 340 Stealth Fuel Pump. Anyone use one yet?

    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...

    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...
