While we're (sort of) on topic, what is the List wisdom on the efficacy
of fitting side vents to the front wings (a la rally cars)? Since,
supposedly, a big part of the issue with Healeys overheating is
insufficient airflow through the engine bay, I'd expect them to help
quite a bit. Or, or they 'useless' as well, since the main overheating
issue is stopped at idle?
Not sure if the louvers on my 100M help. It still gets a bit warm
stopped at idle, but not as much as my BJ8 (but I haven't driven the M
as much, smaller engine, etc.).

<p> An old car should be fit for any normal drive, be it regularly
or occasionally, at leisure or in modern heavy traffic. This
means that many classic cars will need some assistance with the

thermostatically controlled.</p>
<p>An aluminium radiator is indeed a gimmick and does not add

</p>
<p>What improves cooling efficiency is increasing the running
temperature of the engine by fitting a hotter thermostat thus
creating a larger delta T, fitting a more efficient water pump
to increase the coolant flow, enlarging the total surface area
of the radiator, i.e. more rows (up to a point), larger matrix
or increase the air flow through the radiator, i.e. improved
cowling, more blades to the fixed fan, higher engine idling
speed but most of all a thermostatically controlled fan in
combination with a carefully chosen thermostat and thermoswitch.</p>
