top end speed/fast accel

[sheriff steve]

I have 2004 232 rinker captiva with a 6.2 liter motor with a bravo three drive. I have two 26 pitch props on right now. I am running 61-62 at 5200 rpm. How can I get more top end out of my current set up? I WOULD like to run about 68-70mph and get there fast. I am thinking about adding a supercharger and a higher pitch prop to accomplish my goals. My motor has a 9.0:1 compression ratio which should be good for at least 5-8 pounds of boost in stock configuration without hurting my motor. Do I need to change my prop pitch and/or out drive gearing to accomplish my mission?

Thanks in advance,

Steve
