Can't deny it's one of my favorites, but this is a first approximation. I could substitute a Jim Dandy roof rack.

Piotrsko -- Stock fan and shroud, except instead of dumping air to the rear, it goes into a vertical chimney behind each rear tire. It is entrained by the exhaust and the only exit is from the approx. 8ftx2" plenum who's only exit is a slot that run around the inside of the arc.
Where I need help is determining the relation of the volume of air available vs the cross section of the duct. I think this determines the width of the slot.
I think the stock fan wouldn't be overburdened because the exhaust is 'pulling' on the cooling air. But in my original Coanda boat tail, I specified only cooling air because exhaust is corrosive and nasty.
I have the motor in my Superbeetle but I'm not cutting that up. I'm also hoarding a 36hp case but it's incomplete.
