6Stang7 said:The link that was posted to that NASCAR site which said un-restricted flow is better is deceiving. Remember, this is under RACE APPLICATIONS! These are motors which are seeing around 8K-9K in RPM, and air running across the radiator at over 170mph. this doesn’t in anyway help understand how a normal car will function.
This is exactly the point I was making. I am not trying to personally attack Boo Boo Foo in my post on the previous page, but I really don't agree that the site he linked is relevant. You, 6stang7, and I have arrived at the same conclusion regarding the relevancy of the site he posted, and his reply is that he is "the only person who's bothered to provide a third party cite regarding this subject - accordingly, whatever."
I have no desire to make this dispute personal, and I'm sorry if I came across in a way that indicated that to Boo Boo Foo. But, I stand by my observation that the site he is relying on compares apples and oranges and is totally irrelevant to this discussion. Maybe my words were a little strong, and for that I apologize if you took offense Boo Boo Foo, but I must also state that the engineering opinions on this thread have also been pretty demeaning towards people who have posted that are not theorizing and are speaking from personal experience.
For those that have posted, including myself, who are not able to express their opinions in engineer speak and equations, that does not mean we are all wrong. It simply means we communicate in a different medium.
At the risk of posting a personal attack, I'm going to respond to your post.6Stang7 said:ok, then argue against mathmatics.

Why don't I drive around in the AZ summer with, and without a T-stat and tell you guys with the mechanical Autometer guage tells me?
DarkBuddha said:Is it possible (theoretically or in real world application) for coolant to flow through a block so quickly that it is not able to absorb heat from the block? I believe the answer is yes given that heat exchange does not happen instantaneously, but rather it happens over some amount of time.
6Stang7 said:let me refer to to a post i made in another thread.
now let me put this is simple terms since some people will not understand this.
the faster the coolant moves through the radiator, the less time it has contact with that cooler surface. look at the equation is red. an increase in time will result in a lower temp. more over, your idea that the coolant would then spend less time in the block, therefore not receive as much heat is flawed to a point. you are right that the coolant wont take on as much heat, but this is to a point. since the coolant wont remove as much heat, or energy, from the block, that means that the temp of the block will get higher because more and more energy is added to it. now, look at the equation is red again and instead of cooling, look at as a heating function (your k should now be positive where as it is negative in a cooling function). the larger difference in temp between the coolant and engine means less time is required to transfer the same amount of energy. now, wait, there will be large temp difference between the coolant and the cooler radiator, so shouldn’t it all work out? no. the radiator has A LOT less surface area then the engine block, which means there is less energy transfer.
70_Nitrous_Eater said:Actually, heat transfer does indeed begin to happen instantly. Think of this in terms of how the block feals... it's at 1 temperature and the coolant is at another cooler temp. It really doesn't care how fast the coolant is flowing, the amount of heat transfered is the same.
Same think works in reverse for the radiator.
