Ok!! I have a lake rigged swtd with b-impeller... full interior w/ no droop, no diverter, stock grate,just totally stock set-up... i have a 550 hp bbc in it.. im only getting 74.3 mph w/ gps... my question is.. is this about right? i can stomp it from stop and pump will cavitate and just spin out.. i can get right up on plane then its fine.. if i switched to an A impeller would i gain mph or loose on top end? im turning like 5100 rpm right now... Whats the problem why so slow???
