The American crew got home, but we never got the B-29s back. Soon enough, the Reds reverse engineered an exact duplicate. The Tupolev Tu-4.

For full disclosure, the CR in aviation engines is far less than for cars, for reliability purposes. I believe that made the early direct injection systems a bit easier to achieve.

Yeah, about 6.8 to 1 but they also could get 100 inches of manifold pressure with 130/145 octane gas and not blow a jug off every flight...that is a lot of boost.
