Message: [QUOTE="HeavyAssault, post: 447141, member: 782"] As before without any real numbers showing what is really happening at the rear of the heads we are all just making assumptions. At idle the poppet should return the most fuel, as you begin driving creating demand then the return flow will decrease. One would expect to see a PSI drop when using a FP gauge at the fuel bowl on WOT runs. Since the OEM pump already provides enough flow and pressure what are you really seeing with the PSI drop?? You addressed the OEM pump on a good day can support demands up to 190 injectors. So why would OEM injectors "starve"?? No one has the rear head PSI numbers to show what happens. We take the info from one spot and think it is gospel. Without using a larger volume pump you cannot increase pressure inside a larger line. If I hook up a garden hose to my house faucet I get decent pressure. Hook up a fire hose to my house I get the same volume but MUCH less pressure. Increasing volume out of the house connection will only help increase the fire hose pressure. Fluid volume and fluid pressure are two VERY different things. Applications need to match one another to provide the most efficient solution. [/QUOTE]
