You would look real sporty in that Alticruiser.

That's another one that'll be purchased by a clueless wonder who will 

find out that it's gonna take a fortune to fix it.  Likely in the 

boneyard in another year or so.... very sad.



BTW, just saw a new price list from Custom Airmotive.  They've 

officially discontinued overhauls for all GSO 480 and 540 series engines 

due to lack of parts.  They're still doing gearbox overhauls though. 

$10,000 each for just the nose case.  They do still show overhauls 

available for GO-480's fortunately.

The future is near!

What about hanging a pair of these on a Twin Commander?

http://www.centurion-engines.com/c40/c40_start.htm

They just flew a 206 with the 4.0 engine and are planning on doing a  

414 next.

The Duke is flying.

24 GPH for 350HP

That has the potential to be a fine retrofit, but who's gonna pony up 

the big bucks to execute such a conversion?  Don't mean to be a 

party-pooper, but there's just no market to justify it.

I did a fair bit of engineering work to retrofit an angle valve IO-540 

(300hp) to bathtub Commanders and just couldn't come up with the 

business justification to pursue it.

Hmmmmm.......



Maybe if we arrange an elaborate kidnapping we could finally have a

replacement for the GTSIO-520K?  



Still dreaming- but a guy must always have a dream.

Tylor,



There's a guy somewhere in AZ who has a Helio Courier with the 4.0 on it, 

and Morris & I are supposed to fly down to take a look. If AvGas really is 

not going to be available in the long run, maybe this is the solution we 

need!



Hmm, 350hp of turbodiesel power on my 500B might make all the difference in 

the world.

Good Evening John,

 

It is great to se a new competitive engine on the scene, but the weight  does 

appear a little high. If the fuel consumption is as low as quoted, the  extra 

weight can be compensated for by the lower burn, but it is a shame to have  

to add weight at all. I am not at all familiar with the weights of the various  

Lycomings used on the Aero Commanders, but I am familiar with the weight of a 

 Turbo Supercharged Continental IO-550-B. While it only develops 300 

horsepower,  it also weighs one hundred pounds less than the new diesel. 

 

Any comments? 

 

Happy  Skies,

Old Bob,

On the web site, they say the weight in a 414 is about the same total  

install with prop.

They also talked about not needing to change the cowling on the 206.

I know in trucks, a diesel has a lot more torque that the same size  

gas engine. 575 ft lbs.

They claim 45 liters/hr/eng. 12 gallons per hour in US terms.

I am sure someone like John Towner would be interested.

Hi Bob,



Don't quote me, but I seem to recall that the kit will add about 60lbs. per 

side. That may not be prohibitive, considering the probable gross weight 

increase we'd get from the addition of extra horsepower. I'll bet that 

if/when it's approved as a replacement for the direct-drive Commanders, 

they'll specify 300 or 320 hp per engine vs. the original 290.



Chris S. also addressed the cost. Considering that there are 2 aircraft I 

know of on the west coast who've paid a princely sum ($100-150k) to do the 

Merlyn conversion, which is still avgas-powered, I think the market for the 

diesel upgrade is viable.



Just my $0.02,



/J

Good Morning John,  



The engine does sound very interesting.

 

I wouldn't count on getting a gross weight approval. The problem is more  one 

of meeting the noise requirements than the performance requirements.

 

The increase in engine weight could be a problem due to the potential  

structural requirements to carry the engine (Mounts and attach points may need a  

beef up.)

 

Assuming that the Commander structure IS strong enough to meet the  

requirements as is, the airplane will have to demonstrate that it can meet the  new 

Part 36 (I think!) criteria to get a gross weight increase. One way that has  

been accomplished by other converters has been to show that the new power plant  

allowed a higher rate of climb which allowed the airplane to pass over the  

recording devices high enough to meet the new specifications.

 

I doubt if the increase in power will be enough to meet that  criteria.

 

However, if the engine can meet the published fuel consumption figure, it  

should be able to carry a higher payload on any flight longer than a couple of  

hours by burning less fuel at any specified air speed that is above best  L/D.

 

I don't know if the market is large enough to justify the difficulties of  

getting an approval past the Friendly Aviation Attack dogs, but it does sound  

like an excellent way to go.

 

I certainly wish them well!

 

Happy  Skies,
