My 1969 Dodge Charger 500 (NASCAR Model) had two
rear facing scoops on each front fender. This helped
to exhaust pressurized air from under the
fenders.
It also had stainless steel covers on the drip
rail moldings (on each side of the windsheild) which
reportedly reduced high speed drag.
I would think
that the air dam and action of the fan would produce
high pressure in the engine compartment at highway
speeds. Any type of scooped hood would add to this
condition.
I have considered many things with respect to
this situation. I even thought about leaving the
plastic shock opening plugs out of the inner wheelwells
and let some high pressure vent there into the
wheelhouse. But, the small diameter opening probably wouldn't
flow much air.
The answer, in my mind, is a
flat vent in each rear corner of the hood. Something
along the lines of the Camaro Fender Vent or possibly
some louvers.
Our 2002 Crown Victorias have a
big louvered platsic panel fitted to the hood with
1/4 turn Dzus fastners. This drops the temperature
way way down on these cars.
Probably the best
idea is to install a 4" tube into the cowl vent cavity
in the wheel well and run it through and out to a
vent in the fender. But, you could be weakening the
structure in this area too. Who knows?
I may set up
a smoker and watch the path of smoke drawn into the
engine compartment while the engine is running. That
would tell us where the airflow is going.
There
might be some merit in all this. My 1972 Ford Torino
would overheat without a fan, even at 70 mph. However,
my 1967 Dodge Coronet didn't seem to notice at all
if you were on the freeway.
