[DeTomaso] cooler air to carb

[Ken Green]

The discusion seems to have focused on getting into the air stream to get a flow of air.  You also can get a flow from a pressure difference.  If the air pressure above the deck is low, and there are openings in higher pressure areas, maybe NACA ducts on the sides of the car in front of the rear wheel wells, air should br drawn into the ducts, through the engine compartment, and out over the rear deck.

...the post about the engine-cover fans was, you know, kind of a joke...(ask
Mike Drew about that).

Sometime in the future I might write something such as, "As President
Regan would say..." so be prepared!
