[QUOTE="bigrpowr, post: 1462004, member: 806"] it certainly isn't our place to collect data for another company's product unless requested. the factory lpfs is exactly what it is, designed around a 400-440 bhp engine . Ford will never be accused of over-filtration, because they engineered a system to operate at exactly their demands. when tuning and adding substantial power those demands far exceed what the system was engineered for. for the stock pump guys , the H&S kit is simply offering reliability , and superior filtration along with a superior air/water seperator . the added flow is not necessary on a stock HPFP . now a stroker HPFP or a dual HPFP will demand a substantial amount more of the fuel supply. many with dual fuelers have found that attempting to call for more pulse width in the tune, that rail pressure drops , because when the hpfp(s) are starved , rail drops , it's pretty common knowledge . some pumps keep up in the beginning , but they work their butt off , and typically require 100% clean filters at all times. in my case i ran into a case of fuel temp , where my pump was working so hard it was over heating my fuel , putting my truck into limp. i swapped to the H&S unit and never had an issue again.
