Hey GUGS,
We are on the same page. Yes, the only way to find out is to do dynamic testing. Run it on your boat and see what happens. Some engines will like it other won't. I'm still surprised that the front carb on a tunnel ram can actually get enough air with the scoop on backwards, I guess that venturi effect is bigger than I thought.
Sleeper CP
P.S. Edit
GuGS you mentioned one thing that does suck on a jet boat. At some point you hit the wall (ie) H.P vs Drag equation and it takes a bunch of H.P. to see any change in speed. Once we got the open bow CP to run over 100, it would run 102-103 with the 250 hp shot or 300 hp shot of Nos. The extra 50 didn't help. Who knows what dynamics we were up againt: aero,hydro or pump efficiency.
The new combo I'm hitting the river with this year should be far more efficient. I'm hoping to get the stationwagon real close to 100 with out the Nos.
