Want to build a REAL engine?

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.

It would just be for exhibition and racing. Just put it on a trailer
and show up at airshows and wow the crowds by running it.

The first flight would be in an unlimited racer. By way of
comparison, the old WW2 engines aren't all that reliable by modern
standards anyway. This thing should be just as reliable. I can't see
an engine like this anywhere other than in an exhibition and racing
aircraft.

All that said, the superbike engines are bulletproof by reputation -
they get run really hard. The top end is where most engine failures
occur and that part has been thoroughly tested - tens of thousands
have been built and sold. The crank, rods, case and accessories would
be what needs testing.

Not quite, the engine and gear box weigh over a ton, or at least 4X of
the target weight. W&B would be a bear.

It would fit nicely in a full scale F8F.
But it'd be a bit underpowered...

In Europe quite a lot of aircraft are flying with BMW 2 cylinder
motorcycle-engines.

Reliable, good power weight ratio

With a reduction from http://www.takeoff-ul.de/


Our plane is a Cherry BX2 homebuilt from Switserland.

My, that Boxer does look pretty.
Is there an English language version of that site, I wonder?
Or, if not, how much? how heavy? how many horses?

Try this;

On this site you will find a lot of information about BMW engines.
The owner Wolfgang Spang has lived in the US.

He can answer in English!
