Sooo..., if I put in this new Mixing Elbow, I hope to get at least 3600rpm !!
Why would you want to do that?!?!?!
Look what happens to your torque curve at the top of the rev range (second graph)
Way more important, look at what happens to your fuel consumption (top graph) when you get up there!!! At the cost of fuel today, I would stay well away from 3600 rpm and that's not even discussing engine durability.
BTW, this engine curve is a Yanmar 3YM30
I'm also wondering how the water aperture in a mixing elbow increases RPM availability. It obviously does
. Or are we discussing an exhaust outlet that has been reduced to 10mm
