Very interesting and thorough article Scott. Thanks for posting it. I flew B-17 tankers from 1975 through 1983 and had very little trouble with turbos. All of the B-17s that I flew were G models with the electronic controls. We used #8 for 46” of manifold pressure for take off and dialed back to #6 to set 38” for climb and then dialed back to whatever number would maintain our cruise setting of 32” loaded and 30” empty. That was usually between #2 and off. Of course, we seldom flew any higher than necessary. Generally well below 10,000 feet, so the turbos weren’t working very hard.
Occasionally, we would blow a fuse in the amplifier box for a turbo and TBM Inc.had those amplifiers in a rack inside the crawl way just aft of the front entrance door. We had a spare amplifier box and would have to crawl down into the walkway to switch out the boxes. Fortunately, it just took a half turn with a common screwdriver and then pull the box out and slide the replacement back into the slot. It always made me a little nervous kneeling in the walkway in flight a foot or two from the front entrance door/ escape hatch. All it took was a sharp rap to open that hatch.
