Vance,
What kind of pressure increase was seen at the base of the windshield.
I have long thought about doing the cowl induction for my non-turbo
diesel truck
Thanks
Steve

Chuck:
The area at the base of the center of the windshield is actually
a high pressure area when the car is moving, and is a good place to get
high pressure air. If you louver that part of the hood, I suspect that
the flow through the louvers may well be 0 or even reversed because of
this high pressure area.
You may recall GM using an option called "Cowl Induction" on
their muscle cars of the late 60s/early 70s. This was a bulge on top of
the rear portion of the hood, that allowed this high pressure area to
feed the carburetor. It was very effective, even though it was counter
intuitive. Naive hot rodders thought that a scoop should point forward
into the oncoming air, and not "backwards". I don't know why it isn't
used any more, other than the possibility that it makes the styling of
the hood look a bit odd.
Cheers,
Vance
