imagine that this is really a problem.

I'm sure it does and I've heard it a lot. I have seen racers with the
opening capped and they have had problems (duh).
Yes, there is coolant around the cylinder but what about the combustion
chamber?
The valve doesn't just allow water to circulate to the core (which in itself
sheds heat) but having been through the core it returns to the front of the
engine (circulates).
But to put all this in perspective what can cause problems on highly tuned
road engines is different from a racer (which never has to idle in traffic
and always gets a good flow of air) and different again from a standard
engine (just doesn't make much power and therefore heat).
Other views? experiences?
