Just wanted to know what kind of injector duty cycles the boosted guys are seeing with a given engine at a given amount of boost. For Example, here is my info
4.8L
11psi
43#ers @ 84%
I need all the info I can get, thanks in advance guys

I was:
6.0l
12psi
60# injectors
Walbro 255lph
Hotwire Kit
.....I can't remember what my IDC was :(
What pump are you running?
Farmtruc has:
60lb. Badass fuel system consisting of a1000 and -10 feed lines. Rails and external regulator.
Idc at 92% but fuel pressure is at 65psi
made 891hp
Dragalance has:
stock fuel setup w intank walbro. 48lbers. 8psi turbo
idc at 100%. Made 525hp
just about right w a walbro and good fuel pressure
Good fuel rails and an external regulator will drop idc significantly.
Excuse the typing iPhone here
What size engine does the dragalanche have?Quote:

When it was on 12psi during a dyno session, I saw the real time HP read show 584 around 5000rpms, so I was hoping it would hit 600hp with larger injectors and a better pump/regulator/rails.
Maybe when I get time I'll pump it up some more, but I know the rearend won't hold up.
6.6L fuel cell 4303 magnafuel 18psi 83lb motrons 138% Base set from 40,45,50,60... swapped pumps to MUCH bigger race pump only to gain 30hp in the middle... This was my Third fuel system build... and i am SICK... going to a single -8 from the tank with a single 4 barrel and stand alone fuel cell :)
