    XXX charger injector selection

    I plan to run a XXX Charger with stock ecu and would like to know what injectors I should use with this setup? What should I run my fuel pressure at? I plan to run a RRFPR. The air temps will be above 90degF.

    IMO your not gonna run that SCer correctly with an injector big enough without having a Begi setup.

    yes you will need a rrfpr as well as a begi to dial in your afrs correct.. or spend the 1000 bucks for all the CMD stuff but I much prefer the begi.. mechanical fail safe and easy to adjust on the fly if needed.... ive been using one for 2 years issue free

    If I do run a RRFPR with a Begi what Injectors would I need with this setup?

    bosch 48s maybe bosch 50s depending the climate and altitude but the bosch 48s will work well. im running a 140 on bosch 48s and it works well... seadoo runs there injectors straight from factory on 100 percent duty cycle at wot.... so those that say 48s arnt enough.. maybe in some places they arnt.. but 48's or 50's will work just fine in my setup

    I ran Bosch 48's with a rrfpr and stock ecu for a year without issue. It would turn a 15/22r through an 83mm to 8000rpm at 3000ft. I can't imagine what it would do near sea level.
    Good luck!
