Sonic 31 SS Questions

I guess this is a question for BBlades. Brett I have a 97 31 SS with 502MPI MAGS. I have 26B1 labbed by merc now turning 5050rpm at 70 to 72mph depending on water conditons and air temp. I also have nonlabbed 28B1's that I turn 4600 rpm at 70 to 72mph same conditions. How much do you think you could get out of the 28's for me?

Sorry for the delay.

Per my calculations, 3.31 mph. Of course this is per a model I created. Your results could be more or less. I feel the number is pretty accurate though.
