How much change in nitro content will show indications of performance change outside the test cell/dyno, on the water? I have been told by a few reliable sources over time that nothing is seen in engine performance until there is a 10 percent nitro move (up or down respectively) Some say they have seen noticeable changes with just a 5 percent move. Understanding that pipe, prop and setup play a factor; looking for possible "back to back" or similar test opinions..
