Ok guys, i have been thrown some ideas on some new threads this is going to be for fuel systems only, both low and high pressure, injectors ect. What we are looking for is pump/injector combos, post data like rail pressure with pulse width or tune, and even better HP/Dyno numbers, or track numbers. Keep it on track, im not going to ask you more than once...


I want to keep these theads as short as possible so people dont have to wade in 10 pages of BS to get 1 post of good info

Im going to start off.

60hp nozzles Elite modded pump. Maintained 20k rail pressure with 2.25ms of pw (xrace at the time 2010) maintained full 24.5k rail pressure with 2.0 (x street, 310 tunes)

110hp nozzles (60%) Stock pump... 18k rail pressure @ 2.25 ms pw dyno'd 617 hp bone stock ford pump

110hp nozzles dual fuelers, maintained 24.5 rail pressure @ 2.25 ms of pw, track times are in the 650-675 hp range with some other issues, but you get the idea.

*** all set ups running an air dog fuel system with custom fittings and distribution block at the engine, maintained 5 psi of pressure to the pumps.

My truck with 60's, ported rails, stock hpfp, and Elites stage 2 LPFS maintains 24,600psi on xstreet( tune from march 2011 ), maintains 23,400psi on xrace( tune from march 2011). Unsure what the exact pulse width's are but I think xstreet is 1.9 and xrace is 2.26. HPFP has 60,000miles on it as well.

I'm not saying it will. This is on xstreet so far. I'm having good luck, but have heard that it won't keep up. I will find out more in the spring.

Depends on what version of xstreet he has, some have 2.0 some have 1.75, so pw is very important when reporting
I would be curious to see if it keeps up on xrace, keep us posted im very curious to what its got, im sure its going to be asking alot of that pump.

And craig you are right 150s are about 85% nozzles

I will jump in here too. Custom KEM 345, Elite HP & LP, II pump, ported rails, 110hp nozzles, I am pretty sure it holds 24,500 or so. Will have to check and report.
What is pulse width under in the DD? I tried looking once but what I was reading didn't make sense.
