If you can throw an inline wally, that gets my vote.

Huh? Thats a joke right.

I think an electric pump should be able to get you where you need to be but.

They make it fairly easy now.

Explain y it should be please

I have run a aeromotive Eliminator fuel pump for the last 2 years on e98 and no voltage controller. The end of this year my car made 50psi of boost and the a/f was right at 11.5-11.8:1 and I only have 1 set of FIC 2150's. My base fuel pressure is set to 45psi.

I have tested fuel pressure to over 100psi on just battery voltage and it pumps at least 3.5gpm at 0psi draining the fuel cell.

If I need more fuel pump I can hit it with a BAP and be fine.

I know MAP has tested the Eliminator/2150 combo to over 1000awhp with no BAP.

Any inline Wally would probably be a restriction at this level.

x2, call Marco, he'll have your CC number is less than 3 minutes. :spin:

I ran one of those pumps and they suck to prime. If I remember correctly, Marco use to run compressed air into his fuel cell to push the fuel to the pump to get his car started. One hell of a pump when the car was running, but a pain in the ass to get it started every time. Unless you could find some sort of fuel check valve that wont be restrictive.

Also, when running a mechanical fuel pump, NHRA rules state you have to have a manual fuel shut off connected to your battery disconnect outside of the vehicle in case of crash/fire. Hassle in my eyes.

Is the fuel cell vented?

If not I'd bet that is why it drops!

If it is vented maybe the vent isn't big enough.

For what it's worth. I ran e85 and ran twin walbros with a boost a pump on them has the stock vent on a stock tank. Made 830 @DB never miss fired or showed it was out of fuel. Went to the track first pass I messed 3rd gear. So te next pass I get in 4th and the fucker is miss firing and showing its lean in the wide band so I lifted. So I pulled the log showed it ran the same boat we ran on the dyno so I turned it down 3 psi and did the same thin once I got in 4th. So then i turned it down again and changed plugs and the same result.

When I started I had about 5/8's of a tank and after the passes it was about 1/4 so I figured I'd add some fuel. Cracked the cap loose and I could hear it pulling air into the tank from just cracking the gas cap and it all made seance. the tank was being shrunk or collapsing or why ever he proper word is.

Left tHe gas cap off and boom no more missing and running the AFR it did on the dyno.

Thanks for everyone’s feedback, work has been crazy lately. My fuel cell vent is an an8 roll over valve, so a big vent. John I know you and MAP have had good luck with the eliminator pump.

These are my options listed in order of a preferred solution:

1. Weldon 4345A
2. BAP with an eliminator or 4303 Magnafuel
3. Fuel lab additional pump with their electronic regulator
4 .Mechanical pump
5. Bosch 44 or 255 wally in parallel

I’m such a nerd If you knew how much thought and effort I’m putting into this.
