i am not changing anything right now just had a thought. and this isn't about id vs efiw vs whomever.

with the higher base pressures, injectors have been to get more power out of them (or am i wrong) 1000's flowing more like 1500's. on gasoline.

in 06 i purchased a weldon db2015a. it is rated at 1000hp on gasoline efi. looking at the site, i didn't pay any mind to the fact that it is the only db pump from weldon rated to 160 psi. 85-115gph at 160 psi.

i have rc1200s in my setup now, and am approaching the 1000hp rating.(thats at the crank) im a little over 700 now. I'm just wishful thinking actually.

but to the question, with an injector that can handle the 100 psi base, knowing that there is another 60 theoretical psi in the bag, what can this pump handle?

or is it based on the max of the pump and will hit the wall at 850whp give or take?

just a little curious.

thanks in advance.

It's a trade off with pressure and flow. Once you start increasing pressure you start losing flow.

I'm not sure about the specifics of that pump so I can't help you there.

 

I have the same pump. We also had the same pump on Avons car that made over 1100WHP without an issue. The pump will handle over 1000hp. In one of the I.D. threads Tony posted that the 2015 is the pump to use for 100psi base.

 

Weldon D2015 or DB2015:
(lb/hr)
685 @ 0 psi
660 @ 20 psi
615 @ 50 psi
585 @ 70 psi
540 @ 100 psi
500 @ 120 psi
475 @ 140 psi
450 @ 160 psi

Just pick the base pressure you're going to run and divide that flow number by .7 (for gas) to see how much power the pump will support there. At 100 psi: 540 / .65 = 830.77 observed crankshaft HP. I'm using .7 (BSFC) to be safe, some may say .6 or .65

Just keep in mind that ECU's quit opening injectors at 120 - 130 psi (delta), so even if you have the pump flow there, you're going to be limited by the injector drivers at some point.

ID1000's can outflow the 2015 by ~40 lb/hr at 100 psi. So I'd say you need to stay under that.

Manufacturer's HP ratings are typically garbage unless they specify the pressure and BSFC they're rating it at. How many people do you know making 1000 HP on an Aeromotive A1000? No one, because you'd have to run a carburetor on gas to do it.
