What's up everyone? I haven't been on the forums much but i'm back with some questions because the modding never stops :headbang:. Anyways, I was researching about water pump upgrades and I stumbled across a few threads from the lightning guys/crown victoria guys who upgraded to "Navigator style" water pump. Apparently the impeller on the pump is bigger and uses a low friction bearing to save some horsepower. Do any of you guys run this style OEM Ford pump on your NPI long block or PI long block pre 2001? I would like to get more information on this because I was looking at water pump options. My GT needs a overhaul on the cooling system so this is going to be a spring/summer project.
