1600CC. Kind of ends the talk about direct injection. Still looks like a 6 port but the primary ports (the small ones in the center iron) are much bigger. With a combined end port as on Paul Yaws site, and maybe a mild bridge port, I think 340 HP at 9,000 is an accurate estimate.

 

Maybe 250 HP at 6,500. Going to need three blades and 74 inches of prop.

 

Where do I sign up?
