Interesting Len.  The previous owner of my BT7, Fergus Ross, who owned =
it for 14 years, would sometimes vacation on Long Island, driving the =
Healey with his lovely wife, Ava-Marie, from Oakville in Ontario.  About =
a 12-14 hour drive.  He told me he used to remove the fan on the long =
journey as he got a bit more power.  I though it a bit extreme as I =
never felt I needed more power in the Healey.  I seem to recall (i.e., I =
am not motivated to look it up to confirm) in his wonderful book about =
Bristols, L.J.K. Setright noted that Bristol experimented with different =
fans on a dynamometer and running sans fan produced about 5 extra BHP.

I purchased my Healey while stationed at RAF Bentwaters in England about =
80 miles northeast of London and about 10 miles from the English =
Channel.  The average annual temperature at Bentwaters is 46  to 72 =
degrees F. =20

=20

Perhaps because the temperature was relativaly cool AND the fan was so =
noisey, I removed it.  I found that as long as I could keep moving, the =
engine did not overheat.  I was not in a heavely populated area that =
involved a lot of stop and go traffic or long idles.  Back to the US and =
the Sacramento Valley area, the fan had to be reinstalled.

=20

Returning from a meet on Vancouver Island, the fan threw a blade in =
Washington..  It did some major damage to the radiator.  We were able to =
get the damaged tubes soldered closed and drove home with the damaged =
radiator and without the fan.  Mostly Interstate, thank goodness.  Made =
it home successfully.

=20

I tried an electric fan alone but it was not successful.  I left it =
installed but put the engine fan back on..  The electrec fan is =
thermostatically controlled and only comes on when the temp rises.  I do =
not know what that temp is but I think it is about 180 degrees.   Some =
have suggested that mounting an eletric fan blocks the radiator.  I have =
not found it to be a problem.=20
