You would think with the production of that shroud, R&D would have been done and they would have realized unequal cylinder cooling and adapt the vanes accordingly. Especially when adapting it to Beetle engines....
Just my noobie 2 cents, but wouldn't a + shaped vane placed closer to the fan blades, of course, sized to where the sizes of the "sqaures" are proportional to where the airflow comes be the optimal wy to divert cooling? Vanes closer to the blades prevents any turbulent "void" for the air to be in....couldn't that atleast help the cooling characteristics?
I remember in high school physics class I had a project of explaning why a ceiling fan, doesn't output the same amount of air in all 360 degrees when it's drawing the same amount of air in all directions. It output more air in certain areas. I can't remember why, but couldn't you just produce the vanes according to that fans' optimal air output areas?
I have no idea if that sounds jumbled...I'm on a Starbucks caffiene buzz....work sucks.
