60 vs 80lb injectors?
 
Quick question:

Running normal pump gas (with the occasional race mixed in) (ie. no E85)) how much power will 60lb injectors support on a return style system? I have a 370 w/76gts. I plan on running ~15-17ish psi. Can i get away with the 60's or is this iffy/no go territory? thanks.

deffinately gonna want 80's, my roomates forged 346 with a 76mm garrett is pretty much maxing 60's with 15lbs

Yeah thats what i was kinda figuring on. My friends 408/S88 combo was making the 60's scream at like 115% IDC on like 13ish.

60s are done around 700-750 on gas. You can jack the pressure and get some more out of them though. I'd go for the 80s.

I just went through this myself on my combo. Go with the 80's and spend the money once. Why would you want to be on the edge of what your injectors can do? Id rather feel safer with some bigger ones in there. Just my .02.

A guy has "brand new" 80 lb injectors for sale local to me. I was considering them but I idealy need 60 lb injectors. He is asking $350. I am waiting on pictures from him.

If you are interested I will pass the pictures on and we can figure shipping possibly if I don't keep them for my self.
