How much power can these support? Is 500rw on their ragged edge?
Those will support way more than 500 hp especially if they are rated 44lb at 43PSI of fuel instead of 58PSI.

They're the 58psi rated Delphi ones. :(
According to the Endres book, Fuel amount required = HP times approximately .500 F=HP*.5 so 500HP requires 250 lbs of fuel flow per hour. Divide that by 8 and you need just over 30 lph. If using a power adder use .6 instead of .5 in the formula.
So the 44s will do 352lbs/hr? But that's at 100% IDC, right?
500x0.6 = 300...
A Lucas 42.5 injector will supply fuel for 786hp at 100% and 629 at 80% IDC using the .5 value(naturally aspirated). The injector is truly a 49.1 lb unit.
Crap, these are the Delphi stubby - http://www.racetronix.com/Manuals/In...ultec2_inj.pdf
It's in an FI app, so 0.6 is what I'll use for BSFC.
Any ideas what's avail to fit the stock truck harness/rail?
How about those... http://www.nelsonperformance.com/products.htm#fuel
We have a solution for you!
Lucas Injectors - direct swap for LS1 engines.
42lb @ 43.5 psi , 48lb @ 58psi
These will also fit the 4.8/5.3/6.0L engines in 99+ GM Trucks with our installation kit.
The kit includes LS1 injector clips, heat shrink, solder and butt connectors, and 3/8" spacers to raise the fuel rail.
Price: $300
Installation kit for GM Trucks: $32
hrm... any resistance issues with the soldering of the new terminal ends?
Further down the page are direct swap truck injectors. :thumb:
Aren't those direct the ones I have now? :sad:
:scratching head: What injectors do you have right now?
Them stubby Multitec IIs. Rated at 44lbs/hr @ 58psi rail pressure.
Allen should be able to give more specifics. I am not sure what those injectors are but they sound like their just a little bit larger than the Multecs by their rating.
