Whats the max RWHP that a set of ID1050x's can handle in a Fore return system on E54-E85? Fore 2 pump deadhead return system, an-10 feed to regulator, an-8 lines to deadhead Fore rails. Pumps: Primary TI Automotive F90000267 (Walbro 465), Secondary (staged) TI Automotive F90000285 Fuel Pump (Hellcat pump). Stock GT500 longblock with Whipple 4.0L at 16-18 psi. monoblade, long-tube headers. Decided the return system was the best, even though it costs a lot more. Will buy in pieces over the next few months to make the cost easier. Just want to know if the 1050X can handle my planned setup. The price jump to the 1300x and 1700x is ridiculous lol. Ill cross that bridge if I ever pull the motor and add cams.
