Electric Fuel Pump - 600HP

Since I found my fuel pressure is dropping pretty low at WOT I need to re-plumb and switch to an electric pump. My setup SHOULD be in the 500 HP neighborhood, so looking for a pump that would be good to 600. I'm planning to run it dead headed since I just plumbed the engine half with stainless hose and anodized fittings made of gold.

I was looking at the Mallory 140 and the Carter 4601HP. Anyone think the Carter is enough? It's only rated for 100 GPH, everyone says they last forever and I have a buddy that has been running one dead headed forever, no problems and super quiet.

I'm open to any other suggestions.

Holley black worked excellent on my old 9.80's car(3350 pounds race weight). Ran deadheaded, lots of street time.
In fact, upgraded to a big fancy system and gained zero.
I was well over 600 horse, probably 650.

Holley Black, #8an braided line dead headed.

Another option...Aeromotive 11203 street rod pump, deadheaded, -8 line. Fed my 800+ hp hemi to run 9.50s at 140 mph at 3800 lbs w/ no trouble. Put a lot of street time on it too.

600 hp requires 300 lbs of fuel per hour which is 50 gallons per hour.

I prefer the Carter. It's a Mopar thing.

My original plan was actually a Holley Black, but I keep reading about how the Holley pumps are terrible and don't last long. And really prone to leaks. And I know they can be pretty noisy. It seems the one with the most gripes is the Blue though, not the Black. Is there a significant difference in the quality of the two?

I just bought a Carter 4601, figure my deal will make 470 to 500 hp. It should be able to handle what you expect for power, as long as you have a good system.

I'm running a Carter also,My 440 is a bit over 500HP,Deadheaded too.

The volleys (blues at least) are noisy as all get out. I would rather run two Carters, if one won't handle it, which I believe it will anyway.

LOTS of feedback on Summit about the Holley black pumps. Enough that I decided to buy another Mallory 140, even though I wasn't happy that the price had increased so dramatically since I'd purchased my last one. Not sure if that's because MSD bought Mallory, or if all pumps have gone up a lot since about 10 years ago.

I've use a bunch of different electric pumps over the years on race cars, some no good and some better ones that are real good
You know you will probably want to make more power later so step up now and buy a good pump now
I use Magnafuel pumps now on all my serious cars, the higher HP motors get the bigger pumps
People forget about the amount of pressure on the pump from the weight of the fuel in the line on the launch on cars that have the pump and fuel tank in the rear of the car It doesn't take more than about two seconds at WOT to drain both fuel bowls
Having 18 lbs. of pressure between the pump and regulator is way better than having 14 lbs.

I'm running a deadheaded Mallory 140 in a 600hp SB. When I bought it I was running a 430hp SB but figured the extra capacity wouldn't hurt. It's been 8 years now with no issues. Still primes quickly, holds steady pressure, and is quiet compared to the Holley's.

The Mallory 140 was always one of my favorite street/strip, mild bracket race pumps......... But....... Now they're $306.

I suppose if the quality it as good as it was in the past it's probably still worth it.

A Summit coupon would def help take a little of the sting out of it.

I second this recommendation, I just purchased one for my new car.

One of my customers that does a lot of stroker motor builds and installs uses that Aeromotive pump a lot. I think he said he's installed about 15 of them, only one issue, which was somewhat self inflicted(no prefilter).

Based on that info, I recommended one to someone who wanted to replace their old Holley blue before heading to Drag Week.
Took out the blue, put in the Aeromotive.

I think he said it made it through the first day, started getting really loud, and the pressure was dropping right off.
Put the old Holley blue back on...... Which was still going strong at the end of Drag Week.

Seems like there are those kinds of stories for just about every brand out there I guess.

Most definitely, I've had bad luck with Magnafuel, which the majority of people love, and no issues with my Aeromotive stuff.

There are lemons out there for all brands.

Holley black here with 3/8 line. I have had the Holley black pump on my 63 since 2011 and never a problem. I also had the Holley red pump on it from 2003 to 2011 and it also never had a problem. I have only use Holley pumps all my life and only once had a pump go up on my sons Dart which had the red pump on it and it went bad around 2010 and it had been on his car since 1997. Ron

Mallory 140 for over 5 years.

Street
Bracket race

I have had problems with the Edelbrock Quiet-Flo pumps.
I guess MSD bought out Mallory? Wow the prices doubled!
I have an old Mallory 250 GPH that has been in the car at least 15-years, but back then they were about $250? $458 for a new one is crazy.

Just got back my Magna 500 I sent in for PM, it was rebuilt. They informed me
that I bought it 15 years ago.Went 145 in my 3900 lb brick........

Holley bought out MSD several years back and sold Lunati to Comp Cams, the world changes a lot in some businesses
Pray for the Edlbrock company to remain independent now that Vic JR has past away

With some effort, you could have a far superior fuel system at a lower cost. A Walbro 255lph pump is around $130. A quick-fuel low pressure return style regulator is under $80. Add a line to the car and you're all set.
These pumps are quiet, and are OEM quality made to last 100,000 miles.

Not a typical approach, but blow-through guys do this with great success.

x2 - I use an an in tank 340 lph pump with return to feed a 580 inch Hemi, so far so good.

I love my mallory 140. Same pump since 2005. In 2012 i bought a rebuild kit for it to take to Drag Week but haven't needed it yet. Seems like prices have gone up alot on everything. I would hate to be building something from scratch right now

I looked at Summits site for electric fuel pumps, they sell the Magnafuel Quick Star 275 (GPH) good to 750 HP for $299.00. That is the pump with no attached fuel filter, the regulator is extra. The only Mallory electric pump for Carbs, they showed tonight is the Mallory(MSD) 70 GPH pump for $231.00
Now that Holley has bought MSD who know what parts will be offered for sale under any of the old names

I had the same response typed out, but it seems like hanging a pump off the bumper is the only Moparts approved way...

a 255LPH Walbro is rated at 43.5 psi, at 7 psi flow is higher and current draw is lower. My old BG pump sounded like a chainsaw was in the trunk, I can't even hear the 255. I've got mine in-tank, which is pretty easy with a fuel cell, and will just take a little creativity for a stock tank.

Back in the day I ran 2 blue pumps, the 2nd for N20 fuel only, firstly on my 340 street/strip car, and then on the race only 440 car, dead headed on both. Never had a problem in 10yrs, never had to replace any of them. Whether the quality today is as good, who knows, (should be better?). For 600hp+ a blue or black is plenty and at under $200 if your budget minded is good, the Mallory is no doubt ok but at $306.....too many out there to choose from, most you just don't need as I see it.

So many great businesses in carson city...

No problems in 8 years with this pump

I have always used 2 pumps in line.. at first
just a pair of Holley blues.. then I went to
a pair of Mallory 140s till I went injected..
never had a pressure issue

In line like in series or side by side parallel?

Parallel for volume... plenty of pressure
And if one dies it still runs

So into a Y then a single feed to the regulator.............

Yep

Ran 9.80 at 135 with a dead headed Holley blue and 1/2 inch line. Street/strip. Noisy- yes, reliable- yes. No leaks, plenty of pressure and volume.
And I've one for sale with a regulator if interested...(free shipping in CT only)

I see that Mallory fuel pumps are still available online. A look today shows 18 listings for Mallory/MSD pumps at Summit and 3 at Jegs. But, when I went to Holley's site there is no mention of Mallory even under their "Brands" section. Are the Mallory pumps still being made or is everything I'm seeing just old stock?

I will be using one of these. I "fixed" a 1996 BG400 with Product Engineering seals, and now it leaks.

If you look on Holleys site, MSD is not listed as one of the "Holley" brands, however the MSD Performance Group is owned by Holley.
If you go to the MSD site, Mallory is listed as one of their brands, and the fuel pumps are listed there.

I have had this same pump on my Savoy for about 10 years now and can still run strong. I feed it with -10 from the cell and 1/2" aluminum to the Quickfuel deadhead regulator.

Last summer I installed a walbro gss340 255lph pump
in my tank. 1/2 supply 3/8 return,low amp draw,quite,not
expensive.
So far I like it.
Mike

Mike what regulator did you use?
Gus

I run a MagnaFuel 275 pump. It has done its job for some eight years, this spring I had to change out the pump shaft seal because it started to leak.. other than that no issues what so ever... Run a AN12 line from the fuelcell to the pump and an AN10 to an Aeromotive regulator...

Hey Gus,Holley 12-841
Hope to see you at Norwalk next month
at the big Mopar bash

Buy-the-way I'm nowhere near 600hp,
But it should support close to 600hp
