Questions regarding engines and supercharger
 

Hi, this is my first time post here and I searched this forum but could not find more specific topics to dig into.

I am looking for general to detail information regarding the major piston engines used by Luftwaffe and the type of supercharger associated wit it. If the information could exaplin a little bit more about how the supercharger designed and worked with the enine would be great.

For more specific engine type, I am looking for information to verify what I read about Jumo 213 from Wikipedia and it's cooling system. Since it said due to the open cooling system of Jumo 211, the output had been restricted and that's why mostly used by bombers and transporters.

I could only read English and I welcome any source on line or printed. Thanks for your patience to read this and point me to a place I could continue.
