Am I wrong to assume that those 3 engines were fitted with 3-speed superchargers?
Bear in mind the Ju-88 was a light bomber. Critical altitude isn't all that high so you don't need an Uber supercharger. You want high speed cruise @ 4,000 meters to minimize your time in enemy airspace.
Did they look at puting 2 stage supercharger of the Jumbo-213 on the Jumbo-211.
One problem for the Germans in 1942/43 most of 1944 was the lack of a 2000+ hp engine in any numbers. There is a trickle of Jumo 213A and DB603A in late 1942 or early 1943 but they are opperating in the 1750hp range. The RAF has the Sabre, the USAAF has the R-2800 (though it was initially a 1850hp engine)
Daimler Benz doesn't bother with the DB605 but all the effort goes into the DB603, this is probably easier given the DB603 has been around a long time already. The DB603 if developed at the rate the DB605 was gets to 2000hp fairly quickly.
Junkers doesn't bother with the Jumo 213A and goes straight for the Jumo 222. This is risky for junkers if they fail or are belated but it is not risky for the Luftwaffe since the
BMW 801 and DB603 are already providing the power needed in that 1750hp range. All that Jumo 211 production is going somewhere: mainly Ju 88's where it produces a rather slow aircraft however the advanced forms to the Jumo 211 are adaquete for some tasks. The Ju 88 series equiped with the Jumo 222 is however a 440 mph machine (as Ju 388 )
