    A JRSC at 9psi with 310cc RC injectors what is the maximum fuel pressure I should ever see at WOT?

    TIA!

    For performance, you'll want to have max fuel pressure around 75psi with that setup. Might be a little different depending on fuel type, and other factors.

    With the OE setup and JR FMU the max fp would be:
    55psi static + (9psi of boost * 5 rise rate) = ~95-100psi (the JR FMU isn't that accurate so the fp can conceivably pass 100psi)

    With 310's your flowing 22.5% better, let's assume 20% for safety's sake, then the fp would hover around ~75-80psi with your current setup.
