Default Summarize injector pro's/con's please?

I'm running stock injectors on a heads/cam ls1 with 392rwhp.
I'm looking at running an 8 psi (maybe more later) STS turbo on it.

I have a set of used 30lb SVO injectors sitting around.

I can't make heads or tails out of which injector to get.
(and I could use some help on sizing too...)


Siemens, Mototrons, SVO, Delphi, Accel, others?

What are the major pro's and con's of each?
(limiting the comparison to stock impedance levels)


Maybe if we get a good summary, this can be a sticky.

Nobody wants to start? I figured this would take off like a "what muffler is best" thread... :lol

Looks like 50lb would do it, if I want to run up to 97% duty cycle, or 60lb to keep it at 80%.

That's based on 600rwhp as a target, or 750 crank hp. Using .6 bsfc for a turbo.



Still curious about which brands are recommended over others, and why....

I already ordered a set of 36 Lbs/hr Bosch. My reasons: I have a set of new 38 Lbs/hr Lucas and one of them sucks. GM installs Bosch so they can't be too bad, they worked fine for me. SVO are probably good also, but I don't know them.
It's a pain to find a company that ships oversea, the first I find only has Bosch in the flow I need.
I looked around a lot to find out what is the best: apparently they are all ok. I just would go for a flow matched set. Better if with a flow test certificate.
