<VV> Engine compartment heat

[Mark Durham]

James, the regulator is in the engine compartment regardless. being on
the engine will have a different heat signature, but As for me, I'm on
my third year with a high amp internally regulated alternator with the
correct Corvair fan with no issues. Mark Durham

Ron:  Maybe, but it would be really hard to prove or disprove.

I know my example is probably an extreem case with the turbo and all.
In my experiment, I stopped in a small town after about half an hour,
shut it off and opened the deck lid.  Probably less than a minute, and
it was that hot.  I had marked it up before leaving home.

The question was the affect of heat on the internal regulator.  Which
is a unknown, and the subject of this discussion.  Once the engine is
no longer running, is the internal regulator, which we assume is
realitively cool when running, immune to he affect of heat sink-ness?
 I suspect not.

Like I said, my experiement was/is probably an extreme case, but it
has some value for this discussion about engine compartment heat.  My
car had the stock external regulator.

Rather than fully open the engine lid at shut down, I make mayself a
small metal support to leave the lid open after shut down on really
hot days, just to speed up the cooling process and reduce the heat
sink time on the various components, including the now stagnet oil in
and to the turbo.  And yes, I did remove the support on start up
because I knew then and know now driving with it open about a inch or
so would suck hot air into the engine compartment.

Your temperatures may vary

BUT, while running and even while climbing mountain grades the engine
compartment stays cool!  You can always open the engine lid after parking.
