Speaking of Cooling

It's even sillier than that. They show a cooling system that guarantees the
area around the exhaust valves -- the hottest part of the engine toward which
VW directs the bulk of the cooling air -- will get NO AIR AT ALL. (Kinda hard
to keep an air-cooled engine cool without any air :-)

Read it for yourself; infomercial in the May issue of 'Sport Aviation'. Even
funnier was having the Air Apparent pop up on the AirVW mailing list to defend
the engine's lack of cylinder head cooling with pseudo-science.

The tricky bit is the way they've mounted the CHT sensor so it gets cooled by
an air-blast. Then measuring the temperature of the crankcase rather than the
oil inside it. Not too hard to 'prove' an engine always runs cool, eh? :-)

Regarding ignorance part, one definition holds to be "A willful
neglect [of]
knowledge". There's no shortage of that type of ignorance on the part
of some
vendors.
