I have a berk e pump with a AT AA imp,DPS inducer and stuffer installed powered by a mild BBC in a 21 foot open bow boat, it has just the rock grate on it and I am asking if adding a loader will help at all, like the SE version from Berkeley?? Current performance is top speed yesterday on gps 59.2 at 4300 rpm, it is great out of the hole too compared to the stock pump with a Berk A impeller that was not in bad shepr or worn and beat up at all when pulled apart and would spin 4600 rpm which may not have been accurate as the tach went bad right after all the pump work and would do a best top speed of 64 but was not nearly as responsive out of the hole.
