The alteration youguys see on studebakers hasn't been
legal for some time, many of these cars have been on the salt for 30 or 40
years and this was a popular thing to do before it was made illegal . These
cars have this modification grandfathered to them. Just like there are a few
4 wheel drive roadsters that are no longer legal. Like I said earlier,
walking around the pits to see what is legal in a class will get you into
trouble, and know one preticularly cars what you do as long as its not a
safety item until you qualify for a record. If set a record in my class with
a car that I see as not conforming to the rules I ' d consider protesting
you. You need to remember that when you go thew inspection the inspectors
are not looking at you car as to class conformity, they are doing a safety
inspection. So follow what the rules say in altered, no areodynamic
alterations to the body excepting the covering of openings with flat plates ,
no airdams unless they are fActory, no flush mounting of window glass, if you
want to build a comp. Coup build one. If you are building an altered from a
modern marshmellow car its more areo stock than I could ever get my Studebaker,
Whatr they have going for them is looks and overall length. In my opinion you
will get into hot water venting high pressure areas thew body panels. L.

Subject: Re: To Duct or not to Duct, That is the Question...
hello mayfield,(racers),i pretty much agree with your interpretation , and
along with yours would come the logical deduction (no pun intended) that
ANY penetration consists of three elements, an intake, a ducting section,
and a vent, weather it is a home air conditioning unit like your example,
or the other extreme such as a hole in a piece of aluminum foil, in which
the "intake" would be one face of the foil, the "duct" would be about .008"
long (the thickness of the material), and the "vent" would be the other
face of the foil which the medium (air in our case) flowed towards.
therefore, a commercial naca duct placed in a body panel would also consist
of these three elements, which leads us to the original question - is a
naca duct in a hood or fender considered a duct or a vent (or both !) ?????
