High Flow Low Temp Thermostat?

Even if it did all it would do is make the fan run higher right??

I had a stuck thermostat and it made my fan run stupid loud all the time.
 
Ah ok in that case its something to try out.

Not looking to solve any problem. I spend some time lurking on the Jaguar Forum and many on that site use EuroToy's for performance upgrades. Just thought the Low Temp High Flow Thermo might be an easy/inexpensive add that might add a few ponies to the LS via cooler operating temps.
 
It would if you could find one that fits and was like 180*. I went looking a couple of years ago and found nothing.
 
Actually, the factory-design temp is most efficient. And the ecu has the higher temp as part of the equation and will be thrown off by a less efficient temp. Leave well enough alone.

Exactly.

Look at it this way. Any and all heat being thrown off is just wasted energy. Now you want to throw slightly more heat away, so you would be wasting slightly more energy.
Also, the more coolant flow, the more power required to turn the water pump, so the less power left for everything else. I know that this seems to defy common sense, but the more the water flow is restricted, the less work the water pump will do, so the less power it will take.

There is also a median temperature at which metal wear, fatigue, strength, etc, is optimal. Being too cold makes the metal rigid and brittle, meaning wear increases from friction and it could snap. Too hot causes loss of strength and malleability, meaning it deforms or breaks. It's been a while but I seem to remember from the machine shop days reading that a lot of the common cast metals in car engines were optimal around 195.

Obviously this depends upon the materials in question, but the point being that too cold is just as bad as too hot mechanically.
