It's like the thing, if you put hot water out side it freeses quicker
than cold. Don't ask me why!
As far as I was aware this thing of having a slow flow is correct.
As far as this removing the thermostat thing goes what a load of
compleate rubbish! If you wan't your car to be better cooled, and
better coupled to the engin, you don't try and speed up the flow rate.
What you do is you buy a nice expensive cooleant which has a higher heat
capacity and boiling point than normal. Thus you will find you can
transfer much more heat with 1cc as with 3cc's of normal coolent.
As for the question of why does the walt cool quicker.
1. Think of it like this hot water and cold water have two different
dencities. Cold water being thick in comparison to hot water.
2. When you have water flowing slowly through a pipe you will find it
goes through the whole of the pipe. When if flows fast you will find
that the water round the edge will stay still because of friction, and
you will get a very fast flow through the middel. If the water round
the outside is a different temperature this will make highten the
situation. When your trying to cool or heat the situation will be the
same, you won't transfere as much heat.
3. When my parents had an extension done, they had to put in some long
pipe runs for the central heating. For the normal heating they used
large pipes, for the long run they used small bore so that the water
would not cool down as much. Indeed compared to the long runs that
serve my room, using the large bore pipes the raidators are about 10
The enginers who designed the system would have chosen a flow rate which
allowed the coolent to pick up all the heat it could, and transfer it to
the radiator minimising the effect in point two.
So the best way of cooling your car is to go for a good high heat
capaciry coolent. A normal flow rate, and a perssurised system,
converting the overflow bottle. So as to rase the boling point.
Oh and when you put you fingers into a fast flowing streem of hot water
complared to a slow flowing streem you don't burn quicker you burn
