Nostrum pairs a direct injector 96% larger than the factory 3.0 EcoBoost unit with the Big Bore HPFP kit flowing 47% more than the stock pumps, and the interesting part is what that lets the calibrator do: commanded rail pressure can drop from the factory 24 MPa to around 20 MPa and the engine still gets the fuel it needs. Lower commanded pressure means less asked of the cam lobe and the pump for the same fuel mass. This is the last rung before the pump itself changes.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eA 2020-2023 Explorer ST or Aviator already through Stage 1 or Stage 2 and short of injector on ethanol\u003c\/li\u003e\n\u003cli\u003eBuilds where the calibrator has asked for room to run a lower commanded rail pressure\u003c\/li\u003e\n\u003cli\u003ePolice Interceptor Utility 3.0 EcoBoost cars, which Nostrum covers here and not on Stage 1 or Stage 2\u003c\/li\u003e\n\u003cli\u003eAn upgraded-turbo Explorer needing injector capacity now and possibly the Goliath later\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBig Injectors, Lower Rail Pressure\u003c\/h2\u003e\u003cp\u003eA high-pressure DI system trades pressure against hole size. Chase fuel mass with pressure alone and the cam lobe, the pump follower and the pump all take the load. Fit an injector nearly twice standard size and the same fuel mass arrives at 20 MPa where the factory system runs 24 MPa.
