Electric Fuel Pump Woes

[ykf7b0]

I have a street/strip 440 with 175 hp shot of nitrous and I'm having trouble finding a reliable, quiet, and performance electric fuel pump. On two different occasions I have used Mallory Comp 140's, and also tried two different Carter 4106's. I have a return system in place and the pump is mounted externally. I would like real life experiences with pumps approaching at least 650 engine horsepower please. Again, this is a street car with mufflers and the engine is making over 500 hp without the 175 hp shot of nitrous.

I use Aeromotive stuff on both my cars. The SS fuel pump is good to 750 HP. I use filters and regulator too, along with -8 fuel lines.

Quiet and electric fuel pump cannot be used in the same sentence unfortunately.
Maybe get an in tank one?

Lots of flow, and (sorta) quiet, means a gerotor pump to me. I have had great service from a Mallory 250 deadheaded. I bought mine for about $75. Now they are over $600. Ran nines in an n/a small block with mine. I'm pretty sure it can support 700 hp. It was quite a bit quieter than a vane pump too.
If I were doing it again? I would probably go with the holley gerotor. (Holley wants to sell holley pumps, that's why the Mallory is $$$.)

Maybe a little late to the party....?
I run this one. Noise is low, flow is excellent.

Do you have a photo of your installation? (how is the pump fed)

If I was you and noise was a concern, I would run a pump from the main tank sufficient to support just the engine itself.

Additionally I would install a small stand alone cell/pump combo filled with race fuel to supply the nitrous system.

So, only flowing the additional 175hp worth of fuel when needed and in a safer manner.

I would agree with IMTMD8. My intention was
to bring your attention to the brand.

I have recently plugged a vacuum port on my regulator that was in use with the Mallory pump but I capped it off after installing the most recent Carter 4106 and it seems to be performing well and holds my 6.5 psi setting. This pump isn't very loud and I am pleased. I contemplated installing a stand alone fuel management system 20 years ago when I was a legal and regular strip racer but never followed through with it. This car is mainly a weekend cruiser now and sometimes my Sunday church ride. I keep the nitrous kit functional and always have a fresh bottle just in case..................
