Since there will always be such a point in the intake tract somewhere, it only makes sense to (if possible)keep it where it actually helps. The choke point at the throat actually helps to turn the air around the valve and into the cylinder. If the smallest cross section of the tract is somewhere upstream of the throat it is only hindering maximum air flow. Of course in some cases the physical limitations of the castings will make it impossible to keep the minimum CSA at the throat, but that is a separate issue. Ideal and practical aren't always on speaking terms.

Just one thing, I'm still no clearer as why we want the valve seat or throat to be the choke point? IS it to maximise velocity near the valve?<br />Thanks, MiloMilohttps://www.blogger.com/profile/05185783656452922771noreply@blogger.com
