AEM 320 fuel pump??

[james432]

Dose anyone know if this aem 320 fits in the stock fuel hat?I been looking all over online nothing about it..

 

[james432]

Well what's the best fuel pump to use with the stock hat??

 

[07 Boss]

For what? I have a GT500 dual pump. Do you need more capacity than that?

 

[james432]

I justneed alttle more than stock I'm been running 100 shit nitrous going to 150 just want a little more..

Everyone seems to go through their fuel system in stages..

boost-a-pump
gt500 dual pump
return style

I think you will be fine with a boost a pump. I just did the gt500 pump in mine so I will have room to grow. If you are going to swap pumps I would recommend that route. The pumps are a little tricky to install so I just did it once and wont have to upgrade again for awhile.

GT500 pump is not just a pump but a complete system.
Dual pumps, a second Fuel Pump Driver Module (FPDM), and a wiring harness from the battery back.
I've been running a similar setup that Saleen had put together before the GT500 came out.

Yea I just want to do something in my stock fuel hat

It's a replacement for your stock hat using the stock fuel lines.

 

[james432]

What about the focus fuel pump kit is that a little note flow than stock??

I meant more sorry spell check damn phone lol

Correct. I should have been more clear. It is plug and play though.

James,

Yes they do and they're the best option IMO for stock hats.

My AEM 320 pump with S&H upgraded wiring supports 530whp on pump gas supercharged. Just my two cents. Jeremy says it will support upwards of 600 with a BAP. It will fit in the stock hat with some modifications

I think I got a Walbro 405? You cannot use a BAP with these - interested for someone to confirm since I didn't realize S&H sold both. Seems like basically the same capabilities.

I have two of those pumps getting ready to go in my GT500 hat but I aslo have a stock hat so I could try to see if it fits for you tonight if nobody else chimes in with some concrete information.

AEM is specific and recommends against using a BAP on their pumps? Their information page implies a voltage range of 12-18v

 

[eighty6gt]

Nah, but TI Auto/Walbro does:

"Manufacturer rated at 400 lph (Walbro / TI Automotive)
Operate under 14 volts only"

My S&H pump was drop shipped from Fore.

Ahh! Roger dodger

....just to add a data point....

I'm using a Walbro 460 from foreinnovations and the wiring upgrade (no BAP), and putting 597/608 to the wheels at 88% capacity (FPDC=0.44 at WOT 6.2k RPM)

So Fore does state under 14volts for the 405 only in regards to a return setup, they do not offer these pumps in returnless. So in a full on application they dot not recommend any voltage booster. I have a dozen or so guys over the years who have been running them with a bap in a returnless setup with no issues. When the bap is installed pre-fpdm on these cars the pump will rarely see that voltage except when needed. Very stout setup. Have seen just under 700rwhp on a turbo car with a single 405 and a bap with my wire upgrade. So short blasts to 14-17volts when needed has not proven to cause any issues that I have seen.

AEM is specific and recommends against using a BAP on their pumps? Their information page implies a voltage range of 12-18v

The aem pumps are indeed designed to operate up to 18volts. This means full time return or returnless no issue. An aem or aem-e 340 with a bap is a very stout setup as well for the cost.

I have two of those pumps getting ready to go in my GT500 hat but I aslo have a stock hat so I could try to see if it fits for you tonight if nobody else chimes in with some concrete information.

Physically you can fit two 340s on a stock gt hat. I have built a few, I no longer offer them personally as they draw too much current for the single fpdm to handle even with upgraded wiring and often suffer hot flow losses in the 25-30% range. It can be done, yes but I do not recommend it. From my experience the largest dual pumps the stock single fpdm can reliabley handle is dual gt500 or dual ford gt supercar pumps. (230-260lph range each.)

The gt500 hat with power feeds and dual fpdm harness will handle dual 340s no problem and that's the only way I build and offer them is on the gt500 hat.

While on this topic I have built two Gt500 hats with dual 405s. Both setups had issues voltage spikes and pressure control issues and didn't support the power they should have. IMHO dual 405 are two large for the pcm to handle even with to fpdms.


So when staying returnless, a gt500 hat with dual 340's and a bap is about the most flow you can get. Anymore than that and its time to go return. At this level you should be looking at pprv delete, larger fuel line, higher flowing filter and fuel rail upgrades anyway, all stuff which a return system already gives you.

Great results, sounds about right, that pump flows around 435lph which should 600 to the wheels no problem depending on setup.

I personally have had mixed results, (some really bad car was maxing the pump at 500rwhp) using a single 465 so I personally do not recommend running it, but good to see its working on your setup. I will build a setup with that pump but often recommend something else that I know is more proven.
