KAD300 - advice on supercharger rebuilds

[aerobat]

Nah ... it really sounds odd / AI generated .

Aftercooling basicly has the aim to increase the total air mass available for combustion since colder air is more dense and more fuel can be burned for a bigger bang at every power stroke . A bigger bang will at the end of the day generate also more total heat .

The idea of an aftercooler cooling the piston crown by reducing intake temps similar to blow with your mouth on the spoon with hot soup sounds funny . Whatkind of cooling effect should an intake air reduction of ~30-40 deg c have when a split second later nevertheless combustion temperatures of +2000deg c will occour ?

Yes , there is evaporation cooling by injecting excess fuel or water injection into the intake of some petrol ( aero ) engines but that another story .

Not saying i,m sure but I bet that a highly boosted , aftercooled kad44/kad300 running wide open has a way higher total heat load to the coolant than its 3.6l 6 cyl 100 or so horses ancestor .

Asking the question a different way will yield this

Yes, a
charge air cooler (intercooler) and forced induction system (turbocharger/supercharger) indirectly play a significant role in cooling the piston, cylinder, and combustion chamber in a diesel engine.
While the primary, direct cooling of the piston and cylinder is handled by engine oil (via piston cooling jets) and liquid coolant, the charge air cooler ensures the intake charge is dense and cool, which directly reduces the thermal load on these components.

Agreed - if the turbo isnt taking over the supercharger A) supercharger is going to get hotter and overworked Hence the OP mentioning the colour of his oil (Probably cooked) and B the Flow of coolant and raw water going around the engine is going to be less which increases the Engine Temps - In My Opinion
