340lph fuel pump
Anyone try any of the 340lph fuel pump that does work as what they say? I'm planning to get one but I heard a lot of goods and bads about the pump. I've also notice there are a lot of the 340 pump out there. Let me Which one is tested and proven... Thanks

Very good fuel pump comparison that ultimately swayed me to get a Aeromotive 340lph: http://realstreetperformance.com/sto...on-test-5.html

I didn't know on boost application that a lower base pressure like 40psi will be better Due to boost pressure. I have my 255 with base pressure of 55psi. I must out out working the pump.

Re: 340lph fuel pump
That just depends on the rest of your setup and the goals you're trying to achieve. From what I've seen, all of those new pumps generally flow around the same numbers..seems more like its down to personal preference. The dw pump comes with a 3yr warranty, I think the aeromotive comes with a 1yr and not sure about the new full blown fb340. Im sure you can trust the performance of any one of them though

Just like I posted in another thread, the aeromotive I think is the best. I made 614 on e85 with 1 aeromotive intank pump and dw1300's. 10:1 81.5mm b16 stock sleeves t3 s366 24lbs

Re: 340lph fuel pump
^ Interesting. I wonder if I could make 500-550whp on my GT30R on E85 using ID1000s/aeromotive intake pump. This would keep me from having to buy the proven and more expensive bosch inline 044 pump.

Re: 340lph fuel pump
Its not possible to go past 100%. Try to keep the duty cycle below 90. My 1300's were maxed (100%) to make 614. So now I have 2000's. As for base pressure on the 568hp motor, it was pretty high. Not gonna say how high for fear of being roasted. lol! My car the base pressure was 60. I'm also using a fuelab regulator if anyone wanted to know.

Re: 340lph fuel pump
It would probably be very difficult, in order to get the 1000's to flow enough you'd need to crank the base pressure up quite a bit. The aeromotive wont flow as much at higher pressures I believe the reason why It worked out for rabbid was because he could run lower base pressure with bigger injectors, which is where there is a more optimal flow for the aeromotive.

Re: 340lph fuel pump
The pressure in a customers accord went up noticably I don't remeber exactly how much but we had to back it down a bit.... if you have id1000s you can use a base pressure of 75-80 psi depending what you are going to make boost wise 120 psi and the pumps fall off pretty hard so 75psi base with 35psi manifold pressure and your at 110psi in the fuel rail which is perfect... that's good for some decent power on gas.

Re: 340lph fuel pump
Just a small reminder if yall didnt know. To get the most out your pumps, wire them to a relay from the battery. I was barely getting 12.5 volts to my stock plug. Now I get a clean 14.2 with the car idling.

Re: 340lph fuel pump
You SHOULD not need to re-adjust your FPR unless your return line is way too small or restricted. I didnt have to change mine when I installed mine last week(up from a Walbro). Base pressure = 60psi. OEM regulator w/ B&M adjustable spring, OEM feed and return lines.
