What lowZ injector should I run?
I’m about to put in a fully built boost friendly longblock (8.9:1) and I’m trying to figure out what injectors I should get. I feel that I will hit a wall with the 57# highZ injectors pretty quickly and that making the jump to low Z with a converter box is the best choice.
It is a c5 and I will be running a D1 with a custom bracket and front mount intercooler. I also have a monster alky injection system on it. My goal is something above 600RWHP. My static fuel pressure will be 60psi. I think 65# injectors will get me where I want to go, but I’m considering 75# since I may jump to a F1R or a turbo kit down the road. What do you guys think? Rob’s post makes me think I can get away with highZ 57s.
Who makes good reasonably priced low impedance injectors?
I’m currently running the Lucas/Delphi ‘009’ 42# Disc injectors and like the way they perform, but they are already at 80% duty cycle and I'm running the biggest pulley I could find.
