ID2000 @ 100psi base?
Can the ID2000 run at a 100psi base with a Walbro 255lph inline bosch 044. What power output with e85? I know the pumps will probably be the limiting factor...Looking to see what I can squeeze as i'm about at max IDC with the id1000

looks like 550-600 is max with the pump setup you have.

Re: ID2000 @ 100psi base?
A Walbro 255 falls on it's face after 70 psi. You'll need a big Weldon, a few 044's, or a mechanical pump to run 2000cc injectors at 100 psi base and not run out of pump.
Those injectors at that pressure will have a flow capacity of approx. 12,000cc/min or 1140 lb/hr.
Ideally, your pump should flow 15-20% more than that, at the pressure you're going to be running.

Nice info from scott posted above . . . It also says in the notes section of that table :
The ID 2000s are capable of more at higher pressure but none of the above pump combos will keep up with the injectors at that point . .

Re: ID2000 @ 100psi base?
Scott pretty much summed it up.
As shown in the above graph, the walbro/044 combo at 100psi with the ID1000's, the 'limiting factor' is the pumps. Therefore, putting bigger injectors doesn't gain you anything, you're out of fuel pump. It will take a lot of pump to supply the ID2000's at 100psi.
Dual walbros doubles the flow capability of a single walbro, but does nothing for the pressure capability, assuming they're run in parallel. Walbro pumps will never be a good option for something requiring over 75-80psi fuel pressure. That's total pressure, not base pressure.

Re: ID2000 @ 100psi base?
for gits and shiggles, I looked it up.
at 100 psi, a Walbro 255 will flow about 180 - 200 lb/hr
ASSuming we pick the strongest pumps in the box
1140 / 200 = 5.7 Walbro 255's
To have any extra, you'd need 7 pumps, and 100psi is still your max pressure, not base.

Re: ID2000 @ 100psi base?
Any pump capable of supplying the pressure and volume.
On my car, with the ID2000's at 3 bar base fuel pressure and a Weldon 2345 pump, i'm seeing a max of 82% duty cycle. Not sure how much power that is, but it's over 1000whp. That's on C23. Max linear duty cycle on the ID2000 at 3 bar is around 92%.

NSCRA doesn't have a rule that says u cant. I asked John about it last year & he said he doesn't see a problem with them. there is no power gain with them just reliability.
kinda like the long threads about the EWP, lol
big $$ motors & safety at mind.
sorry to go off topic.
