General Electric turbosupercharges

I'm new to the forums and I have been reading the old flight and engine manuals that have been posted here and I've really enjoyed reading them. I would really like to find as much information as I can about the design, construction, operation, and maintenance of the turbosuperchargers installed in aircraft. I don't know what it is that makes them so neat to me but I just can't help myself.

I am particularly interested in the CHM-2 turbos that were planned for the VTD (variable discharge turbine) program for the B-36C. Pure prototypes I'm sure that there is little written info about them but I would still be interested in any information you would like to share about the little device that allowed the Forts, Liberators, Lightings and Thunderbolts to zoom above the rest

Here's alittle bit to get you started...I'll find more, but I'm real busy at the moment.
