Fuel Pump

how many gph free flow do i need to run a mild blower motor,440 mopar with 7lbs boost,2 750 double pumpers

[gn7]

120-140 gph free flow, 13-15 psi bypass pressure, with DAMN good regulater! Any six valve pump from edelbrock, clay smith, b&g, etc. P.M. Superdave on this site, he handles clay smith and I am sure he can send you one Pronto

[moparjet]

i need 13 psi at carbs for blower?...im trying to stay away from a return line if i can....was thinking of a areomotive 150 gph and a magna flow 4 port regulator

[gn7]

NO! thats the pressure the pump dead heads at, you set the reg for 5-7 lb hope for at least 5 at full throttle, the reg. should be just fine, Iam just not a big fan of electric pumps when they aren't totally required, my two cents

[moparjet]

150 Gph And Good Regulator With No Return Line You Think Will Be Ok?.....should Be Only In The 600 To 650 Hp Range(i Think)

[superdave013]

those clay smith pumps don't fit to good on the mopars. You will have to grind the block and or pump for clearence. The last guy I sold one to retruned it.

i am using a mallery 140GPH #8 to carbs flowing 110 at 5psi,no return well past 8lbs of boost.i have to get rid of some ignition troubles with the 14lbs i am doing.i have 2x850cfm holleys jetted 88/90 no PV's NGK 8's gaped at .020.
i ran 10/46/129 8lbs,4100lb car.if i can help just ask.i am no expert.at the dyno i got 580RWHP/606TQ at 5000rpm that is all we could get with the ign trouble.

yeah, well if you run mopar you have to expect that shorta crap

hey hey hey....its not my fault no body want to pay for the power....just funnin.....building a mopar is a little harder....thats why i like it (sometimes)

I'm a big mopar guy and I would really like to put a 440 in my boat that's got a 460 Ford. I have a 440 that came out of my challenger but where can I find Mopar boat stuff? Like headers, bellhousing, and motor mounts? Or any other stuff I need

new? glenwood in gardena, ca. used? shop till you drop but don't hold your breath, that stuff wasn't popular in 1963, and what was made was most likely melted for the alum. 20 yrs ago. for headers check with Bassett

my bell housing,water cross over,fly wheel came from dick landy...his name is all over it....dont know of anybody else who has his stuff....mopars are rare in boatshttp://www.***boat.com/image_center/data/520/medium/3359100_0134.JPG

You should post some pics of your boat, it's cool to see a mopar in a boat

The key here is BLOWN.
That said..you never want to run out of fuel. Regulators are restrictors...big time. I tested a 110 gph holley pump way back when and through their regulator it actually only delivered 55 gph.
I know regulators have improved but....it is still better to run a return line and regulate return rather than regulate the delivery. If I were doing this I would want about 200 gph and regulate the return line to get your pressure of about 6 lbs.
Then test it!
Put a fuel pressure gauge where you can see it....even if temporary and see what your fuel pressure is at wide open throttle.

Well if I was to run the carbejemator shit, I would just use an injector pump with a bypass set at 7 1/2-8lbs plain simple and reliable and forget about it, ran that back in the day on the altered never missed a beat!...

what about returning it to tha pump and not the tank?does that work? i would like to keep it simple if i can..running 2 tanks makes it harder to run return lines

[jets4me]

brent return mind at the tee were the tanks come together

[atxwrangler]

couldn't you just plumb it back into the four port fuel filter?that is what i planned to do.i went with the aeromotive a1000 i believe,and bypass regulator.

[VDRIVERACING]

My opinion is a return setup would be overkill for your application. I agree with GN7.
I have good luck with the Edlebrock 140 GPH pump and the four port Magnaflow regulator. I do not use a return line system and turn 7500 RPM. On the other hand, I see other guys using that set up. Maybe it can't hurt, but it's just extra plumbing for your engine.
I would use 1/2" fittings at the pump, #10 line to the regulator, then you can go #6 line to each carb inlet. Also, spend a little extra on the fittings and use the radius bent elbows wherever you need a curved fitting. I have 1150's on an 8-71 and have no fuel delivery prob's.
For initial set up I suggest a temporary additional fuel pressure gauge between the pump and the regulator. This will confirm that your new pump is operating properly. After you are tuned, remove the extra gauge, but leave the port there so if you have a fuel delivery issue at a later date, it will be easy to stick the gauge back in to rule out the pump.

Carter makes a great 170 GPH mechanical pump that I use on my blown 489, 800 hp or so. Requires no regulator, 1/2" lines, maintains good pressure throughout the rpm band. Might want to check to see if they or someone else does Mopar. Less parts the bettah.
