Default How far will 50* go???

Im wondering how much power my current 50 pound delphi injectors will handle.
I know my system is good, but injector is the question.
System starts with CAS/Speed inc Cell, duel filters#10 in and out(one before one after pump),#10 feed to Auromotive 1000, to Speed inc Alum rails, 50* injectors, Out with a #8 return,into a auromotive adj reg, back into cell.
It should be good for some power but again what will 50's do?
Thanks.

Compare 50's at 43 fuel pressure vs 50's at 58 fuel pressure to compare with LT1 guys.

I run my 50's at 61 psi.
Im looking to go to Gen7 and a new motor and i want 700 rwhp.
Im thinking 72's will do it. As i talked to tom and he said the same.
Maybe 83's to be safe.

i have a line on some 60# high impedance that showed promise on my car.. could get you to 700rw and cost less than 50's... but if you are doing dfi as i am, might as well skip to 83's.

The 83's will still idle good and should handle 750-800rwhp.

Another newbie crashing your party! I'm running 95's in my LT1 Camaro on the street with no problems. Idle pulsewidths are in the 1.0 - 1.1 ms neighborhood.

IMHO, you shouldn't bother with big high impedance injectors. Their large mass cannot be controlled by the small electric current available to open them. Result? They are sluggish. My car ran *much* better with low-z 75's than it ever did with high-z 50's. I had jacked the injector offset up to 1.0 ms trying to get the 50's to idle, but the 95's are happy with the *stock* offset.

And don't assume you have to spend serious bux for an aftermarket ECU. My driver box lets your factory PCM run any gasoline injector on the market.

BTW, before you run me and my LT1 outa town, let me say that I'm considering the new intercooled Magnacharger for my C5.
