Trevor,
I think you're missing my point a little. You ask where the heat is =
going if its not going into the radiator. In existing systems, cold =
water from the radiator is going into a relatively cold block. (It's =
cold because of the continuous influx into the cylinders of cold =
fuel/air mix) The cold radiator water doesn't pick up heat until it gets =
into the head and that heat is then discarded through the radiator.
With the new system, you're using the cooling effect which is always =
there in the cylinders to take the heat out of the water from the head. =
The radiator DOES stay cold in normal driving. It's only during idling =
or peak hour traffic that the thermostat opens to put any heat into the =
radiator. Even after a sustained 70mph drive in my Triumph, if you stop =
and open the hood, the engine bay is cool with virtually no heat other =
than from the exhaust manifold, the rocker cover and the top radiator =
header (through conduction?) being evident. The twin SU carbies are =
stone cold and I still haven't figured out whether that's good or not. =
All other engine bay items are also cool. =20

I have trouble with this as well. It seems reminiscent
of a perpetual motion machine or other impossible
situation. Right now my radiator is working, and the
car is at a good temperature. If my radiator in the
new config is NOT working, where is the heat going?
Same with overheating. If my current car is overheating,
the radiator is trying as hard as it can, the thermostat
is wide open, and so on. Moving the thermostat doesn't
seem to have much effect.
