Prototype in the wind tunnel

[MRN I J]

I think the Mercruiser inlet manifold would be ideal for a turbo instalation, Andy Short of BSS parts did one 25 years or so ago, based on a R18 or Fuego turbo

Wow!!! That's got to be the quickest way of taking a stern drive + engine assembly out of a boat - just cut out the rear transom   

Crikey, you're right . . I hadn't noticed that.
But the transom looks to have delaminated and falling apart anyway, so I'm guessing the boat wasn't worth much as a going concern.

Noticed that the "strings" in the center of the engine cover are pointing forward. Good place for an air intake to the engine? Maybe to much hot air there rising out of the outer openings?

Here's a Lotus Elise in a wind tunnel. I always find these fascinating.

Given recent conversations about airflow and vents in the Europa engine cover, it looks like the Elise displays similar erratic air movement in the corresponding area.

Observe the video at the 2:54 point.
They're injecting smoke directly into the area in question.
