OK, the bike's prove you can take motorcycle 4 cyl blocks and create a
monsterously powerful multi-bank engine with them. The Hyabusa V8 is
particularly neat. The 48 clinder seems to be 2- stroke cylinders
which is weird.

For aviation, a big, round, mean, screaming, 1000HP radial would take
the show.

But it doesn't tell you if these hybrids are reliable.

There are a lot more issues with building a custom engine than just making
all the pieces fit together. None of these examples have been tested for
long periods of time at 75% power, and if they won't withstand such, they
serve little purpose other than exhibition.
