Default cobra injectors....

if i was to use cobra injectors that are 39# at 43psi and are 58# at 58 psi (from what ive read) what is the max pressure i could run on these? 60+psi?

i have a granatelli 255lph pump how much pressure can this support (psi wise..)?

my dad finally talked me back into going turbo and im gonna stick with it this time...

i was gonna bump my base pressure up to 60+ and see how much power these could handle with a higher base pressure

be careful with those injectors, they have a split spray pattern and were designed for the triton engine with 2 intake valves.. The injector should hit the center of the intake valve not the walls of the port.. There are 42 Bosch with the ls1 type plug available new or rebuilt that will work much better.
