[QUOTE="blacksmoke.r.us, post: 1536524, member: 5336"] If you know anything about fluid dynamics it make perfect sense. The hpop lines that supply the stock oil rails are much smaller than the oil rail it self and still have enough area to supply volume for injectors requiring more volume. So the smaller diameter hpop lines (pipe) feed the larger diamter oil rail (pipe) lossing pressure which in turn loses volume. If you keep the diamter of the oil rail closer to the diameter of the hpop lines you lose less pressure. So there would be no need for a larger pump to make up the difference. To prove this all FFD would need to do is dyno the truck now with the new rails. Then pull the new rails and dyno again not changing anything else mechanically On another note the only thing that this would affect is the availble volume of high pressure oil for the injectors. As long as the rails hold enough volume for the the given injector it should work. And it is cause the truck is running making good enough power to get in the 6's. [/QUOTE]
