Can anyone rate the primochill Typhoon III?

"running slower" doesnt help dissipate any more heat.... these are closed loop systems, you need to think of it in terms of how many times per minute each molecule of water goes through the rad, not how long its in the rad for.

Well cars have thermostats to regulate flow of water through engine seperate from the radiator so it might not be so cut and dry. Has anyone ever actually tried it?

A thermostat is used to help warm the engine up to operating temperature faster to reduce wear, NOT to aide in cooling. Engine tolerances are built around a constant temperature and the thermostat help to achieve that. Thermostats actually detract from an cooling systems ability to cool.

Ever take the thermostat out of your engine? We used to take them out back in my race car days thinking it would lower temps, However it actually raised temps. They make restrictor plates to replace the thermostat with so you can "tune" the amount of water flowing through the engine because just removing the thermostat in many cases would cause the engines to overheat.

It may be different with race engines but I can tell you with non race engines that on 2 separate occasions I have had the opportunity to run a car with no thermostat and in both situations the car failed to ever get to operating temperature.

I know what you are saying and yes the water will stay cold but the real tell is when you check your egt or oil temp and find out that they are skyrocketing. There is such a thing as too much flow.

Of course there is, I was just trying to point out the actual function of a thermostat which is to set a minimum temperature and aid in warm up. Since automotive water pumps are mechanical and vary based on RPM there needs to be something to restrict the flow to a level where it is actually being effective. It just happens that they build the restrictor into the thermostat.

The point was and still is, Thermostats are used to regulate flow.

Here from the Wiki:

A thermostat is a device for regulating the temperature of a system so that the system's temperature is maintained near a desired setpoint temperature. The thermostat does this by switching heating or cooling devices on or off or regulating the flow of a heat transfer fluid as needed to maintain the correct temperature.


Can we get back on topic now please?

The thermostat is there to keep coolant from getting to the rad from the block. That is the reason why they are set at specific temps. it is all designed around keeping your car at a certain temp.

Race engine is different. They are tuned for the most power you can get. You also tend to run them wide open. This will produce more heat.
