Cold weather MPG sadness

Things that they should have known before they became an O

 

Cold air is dense. The colder the more dense. The faster you drive the more dense. For every 5mph cold air is equal to x amount of weight. ( forgot formula but there is 1 . Temp x Speed = Force against truck )

 

And the brokers wonder why we ask for more money. There are somethings they just dont get that we go thru running a business

 

This is where the old after cooled engines have an advantage. Intake temp stays constant all year round since it runs water temp and not air temp through the grill.

 

I don't agree with either of those statements.

 

Me neither. Hot water cooling air (in a relatively small heat exchanger) vs 100 km/h air at ambient temperature thru a large core. Air to air wins every time for cooling the charge air.

 

Please expain your thoughts.
What im saying is in wintertime if air temp is coming through the grill at 30 if your water temp is 180-200 your intake air temp is 180-200 with aftercooler. With cac intake will be closer to 30 even if your water temp is 180-200 and that can be way to cold for an engine to be effecient on fuel burn. Cold intake air is good but sometimes cold is too cold.

 

Ugh no. When it comes to the air going into the engine, the colder the better.
