BF 109 one of my favorites from WWII

 

Nearly all combat aircraft in WWII used forced induction. Fighters typically used multistage, multispeed superchargers because they didn't have the room to accommodate the piping needed for interstage cooling of the turbochargers. Bombers and a few of the larger fighters generally used both types in series. Some German aircraft, including some models of the Bf-109 and Fw-190, used continuously variable (over a fairly wide range) superchargers that utilized fluid power couplings to drive them.

that I can go along with. But mrbill's claim of turbo charging not supercharging(as known today) on aircraft from the 2nd world war is very hard to believe. And the superchargers were crank driven not belt driven. He makes claims quite often that on their face are just ridiculous.

Like his claims on water injection during the same period. He is mixing up the use of nitrous oxide injection and water injection for higher performance. It was more prevalent with the Nazi's but the British did use it to some extent.

 

There were turbo charged and water injected airplanes in WWII (and fuel injection). The designs have improved, and computer control has improved, but the basic technology has been around for some time:
