Anyone need ~1000hp of fuel flow?

http://www.radiumauto.com/Fuel-Pump-...-E46-P314.aspx



NEW PRODUCT RELEASE!!! For those looking to increase the fuel pump flow capacity of their 1999-2006 BMW E46, Radium Engineering offers a plug and play solution utilizing the most popular fuel pumps currently available on the market.



This kit features a 6061-T6 CNC billet aluminum sleeve that slides over the corresponding pump to mimic the larger diameter BMW fuel pump. The machined "rib" locks into place and properly locates the filter sock in the BMW hanger assembly. The sleeve includes a laser etched logo. For protection, the sleeve is then anodized in order to resist alcohol (E85, ethanol, methanol) corrosion.



The sleeve is also offered with a choice of fuel pump for a complete installation package that includes all necessary parts including a fuel pump filter sock to ensure long pump life. Click HERE for a review of many of the aftermarket fuel pumps offered by Radium Engineering,



No other modifications to the fuel system are required in order to use this product. However, to fix the inherent fuel starvation issue found on the E46, we recommend using this product along with the Radium Engineering Fuel Surge Tank Kit.

Ordered the AEM gas version last night and the Radium fuel rail +FP gauge.

Thanks for keeping the 46M alive and relevant in the mod world.

FYI: If you are indecisive on which pump to use, take a look through this tech article.

http://radiumauto.com/media/techarti...l-Pump-Test-87

We tested most of these pumps for current, flow vs pressure, decibels, flow/dollar, etc.

Which fuel pump would you advice for my car keeping in mind the fuel pressure regulator and fuel injectors flow from ESS VT2-550 kit?

I also considering your fuel rail upgrade. Do i need to worry with engine fire issue if i include the fuel pulse damper option?

How do the AEM variants compare in this tests?

Specifically, the AEM pumps sold with the fuel pump kit (Gas, E85).

Thanks,

Mike-We did this test just before the AEM pumps became available. However, the Deatschwerks DW300, Aeromotive 340R Stealth, AEM 50-1000 Gas, and AEM 50-1200 E85 pumps all flow the exact same (~320lph). They are identical in decibels as well.



Tiago-If you only plan to run gasoline (E10), we would recommend the AEM 50-1000 gas pump. The Walbro 255 would likely suffice but it would be running on the edge at that power level. If you want a quieter pump, use the Walbro 400 gas pump.
If you plan to use E85 in the future, the AEM 50-1200 E85 pump will be on the edge at that power. We would recommend the Walbro 400 E85 pump.

Thanks. I plan to run only at 93aki with 50/50 WMI and i don't mind to pay a bit more for a quieter and reliable pump (still cheaper than OEM replacement). So i will consider in my order the Walbro 400 gas. About the fuel rail, i read the pros and cons about the fuel pulse damper and also some with stories of engine fire due to FPD failure. Can your kit with the FPD option in the worse case be the cause of a engine fire.

We tested our injector pulse dampers in E98 (98% ethanol) alcohol fuel, unleaded gasoline and leaded race gas. These are OEM fuel dampers and have performed very well.



Keep in mind, a fire can be created by any type of fuel leak (fittings, injectors, fuel pressure regulators, etc.)

Thank you for the update. Glad to see the AEM pumps are up to snuff as well.

Great to hear as I added that option to my rail a few weeks after initial purchase. Couldn't stand looking at the "dead-plug" in my rail!

The Radium Fuel Pump Adapter Kits are roughly ~$100 less expensive than an OEM BMW replacement pump.

I've tested a lot of those pumps and they wouldnt get anywhere near 1000hp on E85. And from my testing a Walbro 255 is still a stronger pump than all the other pumps you mentioned that are packed in the same size body. Only because of the fact that as pressure increases all the others drop in flow dramatically compared to the Walbro 255.

A real 1000rwhp on E85 you just won't do with an internal fuel pump. You need to go external. The biggest flow intank setup without going external is 2 x Walbro 255's. But for big power E85 you need to use the peirburg 800 external pumps, they are cheap, quiet, OEM and are rated at 360lph @5 bar. You can only imagine what they would be @ 3 bar but it wouldn't be far off 500lph i'm guessing. I ran one of these pumps on a LSx turbo on E85 making 800rwhp (dyno dynamics) on E85 on the OEM non returning fuel system in the car which only has 5/16 fuel line. I heard a supra also doing 800+rwhp E85 on one of these pumps with -6 fuel lines. But you will never have enough fuel for this horsepower with intank pumps.

At .62 BSFC and 43psi, yes. But that would only be possible with a large high compression engine.

Exactly.

www.lab22.com is doing an S54 turbo build right now using a single Walbro 400/E85 pump.



We will see shortly exactly what that pump is capable of at high fuel pressures using E85.
