Thread: Can I bump to 55 psi fuel pressure?

  1. #1

    Default Can I bump to 55 psi fuel pressure?

    Running a wet nitrous plate designed to run 55 psi of fuel pressure. Are there any issues running this fuel pressure with the Terminator? Thanks.

    The Terminator's fuel pressure can be safely increased to 60 psi (from 43 psi).
    And with the FPR at the rear of the vehicle, it preferably should be set to 60 psi.
    FYI: 60 psi may require a higher output fuel pump due to higher pressure/lesser volume:

    Currently using the 12-800 pump. Naturally aspirated, the engine just put out slightly under 600 HP. Then I’m gonna run in wet plate underneath the Terminator and spray 100 HP shot. Seems like the higher I go with pressure the lower horsepower pump will handle. So I might actually be better off sticking with a 45 psi and just get different fuel jets for the plate.

    As fuel pressure increases, fuel flow decreases.
