[QUOTE="Big Bore, post: 126714, member: 760"] I think the fuel supply for the hotrods and ricers is a different issue because their fuel pressure is MUCH higher since it is also injection pressure and pressure variations will have a much bigger effect. In our case it's only supply pressure, and we have plenty of volume. Upping the pressure beyond a certain point (I think 65psi is the generally agreed upon optimum) has proven to have zero gains and some have even posited it has a negative effect. Also remember, the 4 way does have a regulator, its just before the lines going to the heads, so it's still regulated. I know you know that Tarm, thats for others reading this. I'm unconvinced that a flow through design is capable of more volume than 4 lines feeding each corner without having a drop in volume at the end of the line. Especially with the fitting size limitations at the heads. [/QUOTE]
