Dave,
Pressure Carb, Cool. Kinda reminds me of WW II Radials.

Yep,

I have a pressure carb in the old Bonanza. It's more like throttle
body injection.
The neat thing about it is that it mixes the fuel very good as
indicated by being able to run well lean of peak. Smooth EGT's.
It doesn't get too rough before it quits, just looses power, then
silence.

Dave,
I suspect you have a carburated engine? I suspect it would have
little effect in a multi-point fuel injected engine.

Race car people dimple the inards of the intake manifold to make the
air a little bit more turbulent to help mix the gasses.
During cruise, i keep the throttle off the stops and my egt's smooth
out.
I suspect for the same reason.

So.. by adding a restriction to flow (in the form of some cute
gizmo) you are intending to INCREASE horsepower?

I recall hearing in another discussion group I participate in, that
one of these devices came apart from the suction forces in the
engine.. not what you want happening..

Just got home from work and at this time in the morning the only
thing on TV
is infomercials

So here I am watching these infomercials and on comes the one for the
Cyclone Fuel Saver. Now they claim that it improves fuel mileage
and power
output from the engine. So I was just wondering if anyone has
tried this
little device in their piston aircraft?
The theory makes sense, spinning air in the intake tract to help
mix the
air/fuel better before entering the cylinder. Now the ad says that
this
works in any gasoline burning engine (and they list almost every
gas burning
engine ever invented) except the ad didn't mention aircraft. I
find this
interesting cause if it works really that good in cars, trucks,
motorcycles
ect. ect wouldn't it work just as well in a airplane?

I assume that this device hasn't been approved for use in piston
powerd
aircraft yet or, maybe it just isn't as good as the makers claim!
