Single High Flow Fuel Pumps For E85

[Gareth87]

Running a single 044 now fed from a surge tank which will run out of flow on E85 and I would rather not change my surge tank to a twin outlet if I don't have to.

Can anyone give me any ideas on big single high flow external pumps are up to the task?

Only one that seems to fit my requirements so far is an A1000 from Aeromotive... Would this be suitable?

Aiming for 500rwhp from a 4cyl.

Thanks, G

Im using a walbro 460lph e85 and it seems to be keeping up at around that power level.

Aeromotive a1000 will be fine but quite expensive compared to the walbro 460lph. Is it pure street or mainly track/strip? If it were me id just add another 044.

The Walbro is intank, not sure how it would go as a external

I have a Weldon 2025 and it will pump anything and lots of it but is noisy as all hell

I am looking into the Fuelab Prodigy pumps as they are suppose to be a lot quiter then the Weldon and have some good flow rates

I've heard the A1000 is suppose to be fairly noisy aswell

Thanks for the feedback.. Will look into it now! I haven't seen a Walbro pump to suit the flow I need as an external pump. Only seem to find in tanks.

Doesn't really matter what pump, just as long as it's reliable enough for the job.

@Joshbigt62r - Mainly just my street car and weekend fun. But I would rather future proof it!

You could easily run a Walbro 460 in the surge tank with a few small mods.

If you want a large external, make sure you can control the speed so as not to overheat the fuel. Something ecu controlled like the Fuelab with PWM input is perfect, other brands will require a separate controller.

yep run a walbro 460LPH pump im making 388 kw with 2000cc inj and its fine works a treat

[Gareth87]

Interesting about running the Walbro inside a surge tank. would have to seal up the tank pretty well though.

With the big external pumps, why is keeping the fuel cool so important? Does E85 have a tendency to heat up and cause issues?

[Piggaz]

Hot fuel is never a nice thing.

[XKLABA]

Especially when it's E85

[Gareth87]

ok but what's the effects of warm ethanol in the fuel system and what will I see as a bottom line so to speak?

It looks to me when E85 gets hot it starts to lean out your engine so I discovered at a recent trackday

[scotty nm35]

I suspect hot fuel may also cause the black gunk I sometimes see around injector tips on e85 cars. Molasses is a by-product of the sugar refining process, and that's just what it looks like.

[kaneryan]

im no expert but i guess its the same question as whats so bad about having my oil, coolant, and air really hot.. is it going to make much difference.... well of course you want to keep everything as cool as possible.. not too cool but you get what i mean.

How hard is the Walbro E85 pump to mount in an R33? I have the Tomei/Nismo pump at the moment, and its great, but is a few years old now and thinking of upgrading it. Just not too sure if its worth the trouble of fitting the Walbro pump or not

Hoping to have E85 at the pump here soon. I'm pretty sure the Nismo pumps handle it no worries, but the Walbro one is designed to run 85 and flows more so seems like a smart choice

[kaneryan]

definatly the smarted choise, and is pretty cheap from memory, like $200, it fits into my r34 gtr but from memory the tuner told me all that needed modifying was the connection onto the pump. if your looking at running E85, you would want a pump that is designed for it and with 460LPH pump you will have no dramas in the future when you decide to push more power aswell. i would even upgrade to 2000cc inj aswell so there will be no need to worry in the future

[89CAL]

I just got 1000cc top feeds I have to put in. They will be plenty for the moment

Might look into the walbro pumps a bit more. I just love how easy my nismo pump was to install and how nice it runs. But it wont last forever and I'd rather replace it as a preventative measure rather than reactive when it fails

[cobrAA]

slight off topic,

for non e85, would a veyron fuel pump be higher flowing than the walbro 460lph ?

[Ben C34]

Does it matter?

It probably does. Do you need it and is it worth the extra money?
