Nope out of my experiance. Can't help you on the turbo. Isn't it pretty similar to the ones on the early radials like the 17's? If so maybe those specs can help. Try sending a note or e-mail to the Pima Air and Space Museum, Tucson Arizona. They have some old head mechs there and maybe they can help.
Thanks for the prayers. We're ok just got the new truck finally and preparing to retire in June. Could use a few sheckels for comfort but otherwise ok.
Hope to keep working part time while traveling or at least when we winter in AZ. with my buddy. Gotta have something to do or I go stir crazy.
