Im almost finished with my b series quest for 600+hp. I've been researching but can't really find much info on what kind of fuel pump to run. Those of you who have reached 600+ what fuel pump and size of injectors are you running. Im thinking about getting either id1600s or id2000s but I don't think the walbro 255 is going to keep up. Maybe a aeromotive a1000? Suggestions please. Even if yours is not a b series chime in since it doesn't really matter since all motors are the same in the aspect of an engine needs x amount of fuel to y amounts of air to = z hp

on e85 people are using dual bosch 044's i think there good to 750 or 800hp not sure on injector size though maybe 1600cc and 2000's

I have an A1000 and have had no issues with it at all. If you are running E85 i would definatly recommend running ID2000s. As far choice of pump, If I were to do it again I would have gone with twin bosch 044's. Its alot cheaper and I wouldnt have had to buy the aeromotive pump speed controller. Aeromotive says to not run the A1000 for longer than 45 minutes on full duty cycle.

I made 565 whp on pump gas with just the Walbro 255 lhp in-tank pump and still had some room to spare. But keep in mind it also depends on how your motor is built. My motor is fully built, best parts out there, bored & stroked, Pro 1's, etc. Not every motor will make that kind of power with just 1 pump.

I have since added an in-line Bosch 044 pump in my engine bay after the fuel filter and am pushing just over 600 whp. Might not have needed the bosch, but it's a nice safety catch to have.

So I'd reccommend just an in-tank Walbro and an in-line Bosch 044...both very very easy to install. Just make sure you get the relay for the Bosch.

for that amount of power, get some ID 1000's, keep the walbro intank and throw in a bosch 044 inline. good for 700+whp

Its goin to depend on what fuel he is planning on using. If e85, then the ID1000s are going to be really close to maxed out. That will vary according to how the engine is built.

I forgot to add if he would be using c16

Heres some info that should answer some of your questions; I found it very useful

didnt speed factory just make dam near 800 on the little d16z6 with a 67/65 and some id1000 inj on 2 044's with the same fuel

^^ Yeah, I saw that car in person run at last years IFO. it was truly amazing to see that kind of power out of a single slammer. If I remember correctly, they spit that block in half!

for a "stock head" built motor. two 255's would do the trick. fullyblown kit or just inline.

wally with a 044 inline man have you seen the chart tony has about pumps/fuel/power

eg:R

Will the 044 inline starve due to the 255lph not pushing fast enough flow??

redline1219

No, they help each other out more or less. The walboro/ bosch 044 is a very trused tried and true combination. Its actually the setup Im using on my em1, Im shooting for 600whp also.

Basically the 255 freeflows at really low PSI feeding the 044, and the 044 makes the pressure for the system. at lower pressure the 255 moves quite a bit of fuel

My understanding is the same as others have stated. The 255 will supply the volume and the 044 supplies the pressure.

I would get the full blown hanger and run dual walbro's i have seen them pushing 800 hp s2000s on e 85 with no issues

full blown dual pump with their 340lph pumps!
