I've read most if not all the posts listed in the sticky thread on P-pumps. Have a few questions that I didn't see answered... Not looking for all the secrets revealed just a better understanding of how different pumps get rated for different flow ratings.
Also, I officially claim to know absolutely nothing about P-pumps so I apologize for any stupid questions or misidentified parts of the pump.
Are 160, 180, and 215 pumps all 12mm pumps? What physical differences are there between these pumps? different cams? different plungers? delivery valves?
What years of dodge trucks can I find any of these pumps on? only 94-98? How are these different pumps identified? Will it have the # stamped on the side?
What physical parts of the pump determine the flow rating of a pump?
My guess is: Barrel/plunger size, cam profile (lift), delivery valve, DV holder?, line size, and injector size.
If I buy a stock 180 pump and send it to a shop to be "worked over" and calibrated to XXX cc's of flow. What exactly do they do?
I understand they balance each plunger to deliver the same amount of fuel, but how? The cam lift for each plunger remains the same, the barrel size remains the same, what changes?
Based upon my reading you can have your pump calibrated to a certain flow and then tone it down some if needed (using a different plate or adjusting the plate). But you can't go the other way. So definitely have it calibrated for more flow than you need so you have room to grow.
How much pump is required for different hp levels? Can a 12mm pump support 700 or 800 hp? Or is a 13mm pump required? What hp can a 13mm pump support?
Any answers at all would help me tremendously.
