Injector duty cycle info please

[jetmech]

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]

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.

What size engine does the dragalanche have?

What size engine does the dragalanche have?

has a 6L w/ a small cam, I think around a 208 duration or something, I honestly cant remember.

I was running it on 12psi when i first installed the kit, but never really stayed in it, the a/f ratio was ok below 5000rpms or so, anything after that, I had to let off, but felt a lot better at 12psi, night and day difference.

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.
