NA ENGINE: 17 lbs/hr at 3.8 Bar, or 55 psi/ 14.5 ohms.
SC ENGINE: 51.6 lbs/hr @ 55.1 PSI / 14.5 Ohms based on 380 kPA = 3.8 bars = 55.1 PSI
But, this leads me to wonder if the NA engine would benefit from an injector swap...
I just read through this thread and what interests me the most about these numbers is that they imply that the SRT-6 injectors are good up to 495 horsepower at 80% duty cycle. I guess the challenge in actually making that HP number is lowering the BSFC of the engine. With intercooling and alcohol/water injection, perhaps this potential could be reached.
Lots of tuning potential there!
