    "Feeding the beast

    More fuel was needed to feed the supercharger, so larger fuel injectors rated at 600 cc/min are utilized. SRT also developed a variable fuel pressure system with a pulse-width-modulated in-tank fuel pump."

    The quote was taken from the article: SRT Engineer Explains How Hellcat Hemi Pulls 707 Horsepower - EngineLabs

    The 600cc/min converts to 57.14 lbs/hr.....which you see some injectors rated in lbs/hr. Calculator can be found here: fuel injector flow rates

    It's weird because my modded CTS-V with the same horsepower we used ID850's. Seems like the 600's wouldn't be enough?

    Yes that's some of the question how can these work on a hellcat even when they up the boost? and other makes can't ?

    I'm not sure what fuel pressure the Cadillac uses, but the Hellcat runs 550 kPa (about 80 psi). I bet the injectors are rated at a lower pressure for the 600 cc/min. I also bet most other boosted applications don't run fuel pressure that high.

    I had thought about swapping out injectors, but i'm not sure if it would do any good being stock. What is everyone's thoughts about these? .
