L67 run at 36.5lbs/hr. @ 47-52psi
LT1 run at 24.9lbs/hr. @ 40-45psi?
If I were to acquire a set of 8 running the racetronix 255lph pump and the booster harness, what would I need to tell my tuner the size injector I have?

also do we need to change injector connectors?

 

You need to give him all the info you posted above re the L67 injectors, plus the manufacturer of the injectors. But injectors are rated at a single pressure, not a range of pressures. Flow varies with the square root of the pressure ratio.

The LT1 injectors are flow rated at 43.5psi.

You might want to just save the injectors for the future, since they aren't needed at this point.

 

I am installing a cc306 from the cc503, with supporting mods. I think its time for injectors

 

with the cc306 aren't injectors required?

 

You should get larger injectors if you go over ~360HP at the flywheel.
