Water Wetter

[HUMMERcustoms.com/TAZ]

I did not read everything below to see if this had been mentioned.

One of the main reasons a tstat is in a vehicle is to maintain a balance temp around all cylinders and primarily from front to back cylinders or vice versa depending on start and finish position of water flow. In the newer highly computerized rides this is an important factor in fuel/air mix by computer and also complete combustion in each cyl.

That being said the computer has a range that it in can operate in. If you are doing your own tuning then the cooling issue becomes more easily handled since you are monitoring each cyl. and can tell the computer what You are wanting it to mix in air/fuel. You also are able to handle combustion by even running cooler or hotter plugs in different cyl. and even use hotter firing coil packs on each cyl. and well many other things to get a balance of combustion on all cylinders.

Depending on use especially towing and adding more HP as well torque it is important to have all the cooling you can get. I would like to be able to maintain a 160 degree temp all the time which is not doable. From what input I can get this temp is as low an ambient that computer would like to have the coolant at that would still let computer manage fuel/air above and below. Again tuning yourself allows for more flexibility. I have 160 degree tstat as well as the throttle body water line bypassed and even in winter in middle of country I have yet to reach that low of an operating temp. My dual electric fans are set at lowest setting which is 180. In a hot lap type of run situation I could wire a bypass so the fans run all the time but, it is not recommended by the motor manufactuers to do it for a lengthy period as motors need to cycle to help cool them.

I know this is not likely needed to be mentioned but, equal temps result in more equal combustion at each cylinder. This hopefully gives us more power and equalized torque on the crank down the full length.

Hope this is helpful.
