Ive been working on getting an aftermarket lift pump for the 12 valve truck for a wile now. Just looking to see if there would be any interest in a relpacement lift pump that would flow up to 450gph at 50psi from idle to way more rpm then any Cummins will ever need to turn. No need for a regulator or a return. Can use stock filter and lines if you choose. This product will be made in the USA
 
Ok lets put this in prospective , the P pump needs pressure in relation to power , and I like it to start at 15 to 25 psi , and progress with boost up to 100 to 125 at full power. This rise in fuel pressure lends itself to increases plunger fill, and is a passive timing advance trick. This allows you to run less timing, and have the benefit of timing at full power .



A diesel on kill is lean mean and clean like BSFC around .22 to . 27 lbs of fuel per horse power hour .
So let’s add in a little extra fuel for the smoke show, its make absolutely no extra power, in facts it will knock in in the head about 8 to 15 % , but who cares we need smoke . So let’s really get it sickly thick. at let’s say a opaque meter reading of 100% , which is blot out the sun smoke , because we have to have it , a BSFC will be in the neighborhood of .35 to .40, after that hp really takes a dive from optimal , the big power is there , but it could be even more with even less fuel .



So lets get big ridicules locomotive smoke fueling , and lets make 1200 hp @ .50 BSFC so lets work that back . 1200 hp X .50 lbs of fuel per hour. That’s 600 lbs of fuel. And Number # diesel weights about 6.5 lbs per gallon . 600 lbs of fuel / 6.5 lbs per gallon means you to need 92 gallons per hour at full song, and that’s at say 100 psi. or on a 600 hp street truck you need 46 gallons per hour @ 50 psi

Build me a pump that will do that ,

It would actually be 0% because it would measure how much light it would let through.
 
Mechanical like stock placement, electric like fass, or belt driven like pullers use?
 
It will be just like a stock lift pump, working off the lobe on the cam. It is designed to supply only what the engine can use. I don't think it will ever get to the capable 450gph as I don't see our engines needing that much supply.

I do not want to violate site rules so I'm not sure how much I can say about cost an so forth not being a site sponsor. If anyone has specific questions feel free to PM me.

Comp, maybe you should take some notes from the people with those engines that smoke, they seem to be alot faster than you and don't need a turbo in a bottle to do it, they just need some fuel and water:what:
 
^I believe COMP is pointing out that as long as the pressure is relative, the pump doesn't need to flow a gazillion gpm... his example case being the extreme of fuel consumption, and even then it was <50gpm.
 
:bang...why stop at 450gph? I want to be able to jam somewhere around 1000gph to my "big bad" p7100 (complete with homemade gsk, custom shade tree tunng, no fuel plate, and uber-laser cut dv's...and it still only flows 400 cc's)


...jeeze folks, the friggin tractor pullers USING AND BURNING upwards of 1000cc's of fuel don't want a 450 gph pump...:poke:
 
Just a little FYI- The specs I recieved from tech support said that the stock lift pump, flowing through the stock filter will supply a max of 52.8 gph to the injector pump.

450 gph is probably high. What about a pump that flows around the same as the fass, ect.? Or would the 450 gph pump only supply what is needed and just be working at lower gph most of the time?

Also the stock filter only flows 60 gph, but the filters I'm running flow 100 gph. I think the fass filters only flow 100gph also, but doesn't that make a difference in how much fuel you can actually get to the pump?
 
TimeBomb, let me apologize in advance...my response was out of frustration of what seems to be the recent "bigger is better" theory on anything involving diesel pickups...

I would actually be interested in an aftermarket lift pump capable of supplying more volume, while utilizing the factory "cam driven" design. I do however think that a pump around 100 gph with a pressure regulated around 40-45 psi would be a much more useful and marketable item
 
As I stated in in my post's above. The pump will only deliver what the engine can consume. 450gph is the MAX it will deliver, so if the engine is only consuming 50gph or 250gph that's what it supply's. I feel it's gonna be a great product. No motor's or wire's to burn up.

Here is a pic

gph, my bad. It hit me that I had made a mistake while i was driving to work today

^That pump looks like one advertised in Hot Rod magazine for, IIRC, SBC engines

Do you ever not talk straight out your ass?

How does this work? Are you trying to say that the rest of the fuel is returned to tank through the overflow valve?

There is a bigger picture than just the amount of fuel needed to supply the injection pump, with 13mm pumps it is critical to flow much more in order to also cool the pump, much like a vp44.
Still 450gph might be a little over kill. :Cheer:
