based on standard injector sizing the limited should be 19 lb injectors for 58 psi fuel pressure, NA consumption, 80% duty cycle max (what OEMs limit it to in order to prevent injector lock up) ... or slightly larger...

the srt-6 at also 58 psi fuel pressure (hoping their fuel pressure is the same), FI consumption, 80% duty cycle max should mean they use 36 lb injectors or slightly larger if they do not utilize a 1:1 fuel pressure regulator to compensate for boost pressure counter acting the fuel pressure...

either way, those sizes dictate standard high impedance injectors...
