I hate dynapack, I find it to be a mis calculated dynomometer. But like any dyno at least there is some truth to what is seen in statistical averaging.

The 5252 cross over is just formulaic. NO engine makes a 5252rpm crossover at exactly 5252RPM. It's just a formulaic equation to take any remaining numbers and shift them to HP figures, one reason why dynojet numbers sometimes look over inflated.
My Mustang dyno test report doesn't show the cross over at 5252 (EXACTLY) and I find it to be more accurate. Every engine has a different boreXstroke which will always make the RPM cross over different. 5252RPM is just an AVERAGE that puts all engines into a ballpark figure so to speak.
