Interesting article I found on the Rocket list. It might be useful to all
owners.
Thanks
Nico
After weeks of trial and error, I have finally reached a point where I can
safely say that clocking the prop doesn't just make a difference, it makes
ALL the difference.
Several weeks ago I set out on a mission to run to ground a vibration in my
RV-8. An IO-540 C4B5 with a Hartzell 2 blade prop. There has been a
vibration that I would characterize as objectionable. Common on big engine
Rockets and RV's. The lower the RPM, the more objectionable it was.
I was able to instrument the plane and do some real tests and get real
results with real data. The net of it is that by changing the prop clocking,
I was able to improve my vibration by 83%. And no Im not kidding. You can
read all the details here. http://www2.mstewart.net:8080/super8/index.htm
I captured a lot of data. I sure hope others find it useful. I have a new
plane as a result.
Best,
Mike

smaller 500 series airframe? The wing root being closer to the fuselage
might be the downer... Wonder what 600 hp per side would do to a 7400

Do you have any information on the six cylinder? I was unaware of the fact
that Dick and his predecessors had this in mind.
Just curious, as v-6 engines are usually problematic.

They discussed a future v6 several times before they went belly up.
I don't know what the plans were about the type of v6. There are plenty
of v6s in the auto market, but I do remember the GM 90 degree v6's
(like the Buick 3.8 liter, which was a 75% slice of a V8) were rough
until GM put a six-throw crank in them. After that they seem to have
been OK. Presumably Orenda would do something similar to the GM
exercise.
But that is all speculation.

Subject: | Orenda Rises Again |
It seems awfully heavy, about 660 lb all up. I don't know if this
includes the prop, but if it does, the empty weight gain on a 500 or 560
would be about 300-400lb. With the fuel savings it probably would be
about a 100-200lb reduction in payload.
It would scream, though. >2000 fpm until you passed out from the
bends.

Exactly. I've been thinking the Thielert turbo-diesel in the 500 series
would be a great match. The right power, the right weight, the right
fuel, and its blown to boot.
(Too bad it can't possibly sound as good as a big block chevy.)
With engines like the Thielert up and coming, and small turbines in
development, I wonder how far the Orenda can get?
Hard to imagine a realistic scenario that has I0-540 owners modifying
airframes to put in a radically different gas fueled powerplant to
replace something that is so good at what it does year after year.

According to Lycoming's web site a tsio-540 J is 550 lbs with out
prop. 660 all up with prop sounds about right.

Cirrus and Diamond have announced the 400 Centurion engine will be in
their aircraft factory new.
Look to Cessna for the next announcement in the C206 and their new

But I think it's perhaps too late for the Orenda. The diesels overtook
whatever advantage they had in the marketplace. I wouldn't have invested in
it if I had the money. It's a pity, but it's a fact.

Yea, for us normally aspirated 300HP Continentals or Lycs, it would be a
tremendous improvment, breathing much needed life back into the airframe, as
well as the interest in Commanders overall...

Here the avgas is hit5ing $4+ /gal and Jet-A can be had for $2.99. I
suspect the Theilert Centurion 4.0 would be the better bet if I was
going to try for an STC, but Theilert seems very uninterested in
promoting STCs currently (this came from the company itself). Apparently
they are selling all of the engines they can produce, and want to focus
on Quantity or, even better, OEM relationships (like Diamond or Cirrus)
where they can get the OEM to commit to ordering lots of engines in
future by contract.
Of course, in the airplane biz, such contracts don't last very long,
only as long as the company's next chap 11 or acquisition, but that's
what they're doing.

But I think it's perhaps too late for the Orenda. The diesels overtook
whatever advantage they had in the marketplace. I wouldn't have invested
in it if I had the money. It's a pity, but it's a fact.

th, the mr rpm conversion is still fairly competative. the IO-720 @
400hp per side and 34 gph is not bad. mason

According to Lycoming's web site a tsio-540 J is 550 lbs with out
prop. 660 all up with prop sounds about right.
http://www.centurion-engines.com<http://www.centurion-engines.com/>/
Cirrus and Diamond have announced the 400 Centurion engine will be in
their aircraft factory new.
Look to Cessna for the next announcement in the C206 and their new
aircraft.

about a 100-200lb reduction in payload.
It would scream, though. >2000 fpm until you passed out from the

I saw Thielert is planning a 350 hp diesel engine. That would be
something cool for the 500 series, don=92t you think?

They discussed a future v6 several times before they went belly up.
I don=92t know what the plans were about the type of v6. There are
plenty of v6s in the auto market, but I do remember the GM 90 degree
v6=92s (like the Buick 3.8 liter, which was a 75% slice of a V8) were
rough until GM put a six-throw crank in them. After that they seem to
have been OK. Presumably Orenda would do something similar to the GM
exercise.
But that is all speculation.

Bruce,
Do you have any information on the six cylinder? I was unaware of
the fact that Dick and his predecessors had this in mind.
Just curious, as v-6 engines are usually problematic.

I personally suspect that the 500 series would require a six
cylinder version, which Orenda was going to produce as soon as the 8
cylinder was making money.

I will... BUT, my question is , do you think it would work on the
smaller 500 series airframe? The wing root being closer to the fuselage
might be the downer... Wonder what 600 hp per side would do to a 7400
max gw airframe... Straight up???
