Overmod, very cool. It looks like three eights put together. the exhaust manifold looks homade! 1800 hp from three eights would be 600 hp from each eight, which sounds about right for a marine application 8V71. The only problem I see is the crank is very long. They run to 2300 rpm, but I remember some owners saying they're much happier at 2100 (detroits). <br /> <br />Oh, as far as cylinder pressure being above boost pressure when the scavenging ports are uncovered, doesn't sound right, because the exhaust ports should already be open when the ports are uncovered. Two stroke engines open their exhaust valves slightly early while there is still pressure in the cylinder, the resaulting "pop" gives momentum to exhausting gasses as the ports are uncovered.
