:agree: ..... But recently there was a lot of debate about Water Wetter and other products of that type ...... I pointed out the fact that the Spyder has a Thermostat control etc....... But no-one seemed to get that ...... could be I'm on too many IGNORE lists :roflblack::roflblack::roflblack: ..... Mike :thumbup:
Never tried converting rubber hose to metal for the sake of reduced temps. No reason it could not work.
I am in the process of advising my son in law to remove firesleeve wrapped coolant hoses in close proximity to the exhaust on his LS1 powered RX7 and converting to beaded aluminum tubes to prevent hose failure from the heat.
As for water wetter, the product increases the efficency of heat transfer. Using water wetter in a thermostat controlled cooling system may not lower the temps unless the cooling system is not capable to do that, say in a vehicle with radiators that are too small, or a dirt bike with no fans sitting without moving or has mud blocking airflow.
Water Wetter in a properly designed cooling system, that is thermostat controlled does have benefits. The internal surfaces in contact with the coolant may see a more uniform and complete heat transfer that balances temps. Water Wetter enhanced coolant has the ability to transfer heat into the radiators allowing them to work more efficiently. By having a more efficient cooling system, the one key item noticed is the electric fans cycle less while in traffic.
If you consider how most cooling systems are designed, the thermostat is positioned as an outlet to the radiators. However, the cooling system has the ability to bypass the radiators when the thermostat is closed or partially open. While a non Water Wetter system may indicate as an example 200f on a gauge, the Water Wetter enhanced system may also indicate 200f on a gauge. The difference being less water is flowed to the radiators and more is recirculated.
Adding metalic cooling hoses will not increase the coolants efficency, but will increase the cooling system efficency by having more or better thermal transfer capability to cool air. The engines internal means to allow the water to absorb heat will not change by adding metallic hose replacements.
I know clear as mud, but two entirely different processes and criteria to overcome.
As i mentioned Water Wetter in dirt bikes. This application convinced me after my first use, no more coolant coming out the overflow when no air is moving across the radiators.
Mike, if you did increase the cooling systems ability to transfer heat into the air (increased thermal transfer capacity), you might be able to disable one fan, and add a block off panel to one radiator reducing cooling drag to make the Spyder more aerodynamic. That is a lot of inches square of drag.
