I think you're incorrect as to how to tell when a Corvair engine is 
warmed up. Head temperature has something to do with it, but the real 
issue is OIL temp. It'll take the oil MUCH longer to warm up than the 
head. That's why it's a good idea to run an oil temp gauge - so you 
know what's really going on with your engine - my opinion.

I run with the shrouds off in warm temps because it cools my engine 
better; especially with the AC on. In cold weather, it works pretty 
well for me to just leave my adjustable fan pulley on the SLOW speed 
(1.20). With the shrouds off, that's all the cooling I need. The only 
problem I have is on an unseasonably warm winter day, when it may get 
up to 70 here. The slow fan may have a problem cooling the engine 
during a long drive at freeway speeds. I have to watch the oil temp 
then.
