aem 320lph rb25 fuel pump!?!?!?!?

[MCPcoupe]

So I found out the fuel pump in my s14 is shit. Thinking about getting the arm 320lph. Anyone use one of these?

[OrangeVirus1]

better get a new Fuel pressure regulator too then.

you can get a 255LPH or 190LPH walboro and it would work fine. and cheap like 80$

the 320L is overkill unless you're pushing alot of power on E85.

the new AEM pump is pretty badass! Looks identical to the DW300 fuel pump. If you are mostly stock i'd look at something else even though the AEM 320 pumps are $100

The walboro is shit that's what I had

[smoked240]

I'm running a walboro 255 with my rb25 on E85, only pushing 10psi though. No problems yet! I plan for the AEM pump when I get my new turbo.

Well e85 is pretty dumb unless your running high comp. Anyway how can the pump be too big?,I mean if I run the stock fpr it should regulate the fuel coming out right?

[Flicktitty]

E85 is Great weather it's low or high, Ethanol just allows you to run high compression.

I guess e85 really just prevents pre ignition and detonation. This means you can advance the timing a little more to pull some extra hp. You can tune your car on 93 and make the same power on a turbo car.

How is it dumb? Are you dumb? There are many benefits from running E85 even if your not running high compression. It runs cooler which keeps my temps down. So converting to it already solved one of my problems. Not to mention the limits of pump gas if you plan to run high hp. Absolutely no knock. That I've seen yet. Knock is one of the Rb's worse enemies if you didn't know, which that solved another problem. Just because you're running low compression, doesn't mean you won't benefit from E85 over petrol. It's certainly not going to harm it if done right.

Adding this cause I'm not posting two different posts.
Where I'm from the highest octane you'll get is stamped 91. Now not everyone is 91. One gas station has 89 with 91 slapped on it. So E85 was the only other option. The one downside to running E85 is starting issues in the cold. If its 20 above outside you best have a can of ether with if you wanted it started. An extra set of hands also.. Now I can fix that if I sat down with my Aem and adjusted a few things but I have no reason to drive it in the winter so why bother.

Never said it was gonna harm anything. You can just make the same power on pump gas. And your engine temp shouldn't be high if you have the right set up. There's 1000hp+ cars running on pump.

[smoked240]

I would like to see what car your talking about. Not that I don't believe you, I just would really like to see it. There again 93 octane is available to you, not for me. It's a lot easier to hit 1000hp on E85 compared to petrol. With swapping in the Rb you lose your clutch fan, which does the most cooling. I could have ran it with a custom built radiator. So I'm limited to E-fans. Just having the fans with the s13 front end, limits the cooling quite a bit. With the right setup it would be fine. But I don't have to worry about it now. It keeps it a lot cooler while cruising now.

I'm done shitting on your thread man. Didn't really mean to.

It depends on the rest of your car as to what fuel pump you need / what would be efficient... I have a sr20 and use double 255 walbros... which is completely irrelevant unless you know what the rest of the car is.

[Slip&Sliden 240]

I have not used the AEM 320lph pump. I have however used the Aeromotive Stealth 340lph pump. I seen 4 of those pumps fail in 4 different cars over the last year. Each one was replaced with a Walbro 400lph. The Walbro 400's are $160.00 with the install kit, that is the route I would take.

The stock fuel pressure regulator will be just fine.

:facepalm: so much non sense said here about E85 its insane.

What are your power goals?
what is your budget?
what fuel will you be running?
what size fuel lines are you running?

all these play a factor

Walbros have been crap lately. I have 2 in my car that are old and running strong. I have seen 3 new ones die on the dyno within the last 6 months though. A single 255 walbro is not enough for a proper e85 setup on 4 bar imo either. Your just asking too much duty from it at all times

Misinfo

The misinfo is terrible around e85. Anyone that does it right will never want to run gas, the people that have never ran it regirtate false info and the guys that arnt smart enough to figure it out have nothing but problems.

I know this thread is about the aem 340, but i do know stock wiring is not enough for the aeromotive 340 and i would recommend re wiring anyways.

Agreed I had a lot of voltage drop and had to hard wiring it but after that we were golden

100+ octane (104 on the french rating, a bit different from the US. Our 95 rating is your 91), and 30% lower price tag. Basically, race grade fuel for a penny. I fail to see where using that on a turbo car is dumb, really...

I have been using that for years now. And i am not switching back to standard fuel, ever.

Still, a 320L/h may be overkill for the OPs need... Dont forget the pump uses power, and that power needs to pass through some quite small wiring. You may need to rewire.

[4x4le]

I honestly think most people under pump or at least incorrectly pump their car, especially with e85.

If you look at pump dynos that show the information on what it flows at different pressures and what kind of amperage the pump will draw at different pressures.
I bet anyone that has never seen a fuel pump dyno and looks a few up will realize they didnt know half of what they thought about them.

Anybody using this fuel pump yet?
