so would you go bigger C.I., blower , turbo??

Steve, you've been around these long enough you know the deal. 1000 minimum reliable HP, T400 trans, 29 or bigger gears and it seems to be an 11.5 x 15 is the starting point for a prop.
C.I. equal HP. And power adders are a personal preference for one reason or another.

Nailed it
