DIY TIAL wastegate

Do you think it would be about the same? They are both showing the gasses the same amount of port going up or going down? The pressure is at a dead head, ie end of a blind pipe (capped). I would almost think it would flow more as there is no valve shrouding occuring inside the water neck..? Im no fluid dynamics study. Dang, they are only $50 on Ebay but this could work. The working pressure is 5psi for actuator, pretty light for a turbocharger. explain that elbow.
