A friend of mine asked me about this a while back, and try as I might, I’ve not been able to come up with an explanation.
The Boeing B-29 is said to have been dual Turbocharged. What does that mean? Does it mean that both blowers were suppling the engine at one time through either a parallel or serial connection, or was just one blower used for the engine and the other one for something else like cabin pressure?
It’s over to the engine gurus on the forum

The B-29 was an ultrahigh altitude bomber
and so needed an oversized turbocharger at high altitude to supply enough airpressure to run the engines. This second turbocharger is only run at high altitude at its normal turbocharger is run at lower altitudes. Modern high altitude research planes like the Grob Strato use turbochargers that are larger than the piston engines themselves. check out the link
