[Mgs] Hood Louvers: Motivation for the Question

[Matthew Milkevitch]

Fellow MGers;
I wanted to inform those interested list members about the motivation behind
my question on hood louvers.  At present, my '74 MGB-GT has no cooling
problems.  However, one issue I've always had with my GT is high cabin
temperatures in the summer. I suspect this is due to excess engine heat being
"dumped" into the cabin (the cabin acting like a little like a heat sink).
 Since this is a GT, this excess heat would be retained for a longer period,
much to the discomfort of the passengers.  I was therefore thinking that hood
louvers may, at least to some extent, help to alleviate this issue.  Excess
heat could possibly be dumped to the surrounding atmosphere and not as much
would be transferred to the cabin.  Granted, if air flow is not correct the
louvers may not help reduce cabin temperatures at all...which is something I
suspected and that the collective wisdom of this list has made me much more
aware of.
That was the motivation behind my original question.  Perhaps the question
should now be changed.  To all GT owners...have you experienced high cabin
temperatures in the summer?  And to the whole list in general...are there any
ideas on how these temperatures could be reduced (without removing the GT
roof, that is).
