front, or is that a high pressure area and good for air inlet? "
The area in front of the radiator and support is the highest pressure area
of the vehicle. Ducting air from this area is very workable.
Carry this a step further when the rules allow other than a stock radiator
and use two smaller rads side by side, with one an ice water chilled charge
air cooler and duct the chilled air that passes thru that rad into the carb
or injection. It works! You don't need a turbo to be intercooled. I did
not collect temp and pressure data so cannot back up this statement, but the
car did go "fairly fast".
I believe the second highest pressure area is at the cowl, but never tried
that because the front of the car has always been available.
