Smile IO-550 Upgrade Information

Our website now has the IO-550 upgrade information available. It is still a work in progress but contains a lot of information. Now for all of you that have our tried and true IO-470 engine just wait a little bit and we will also have IO-470 engine upgrade information avilable.

Most everything on the IO-550 upgrade information we now have is the same or similiar to the IO-470. The IO-550 just has a little more power. The biggest problems we faced with the IO-550 was the additional weight on the nose hurting our slow speed handling characteristics. This we found a way to deal with so no problem there. Another issue was vibration which the engineers at McCauley helped us with. The engine/prop combination we certified is very smooth as those that have flown with me in the King Katmai will attest to. As to reliability I still think the IO-470 is about the most reliable engine made. While the IO-550 has evolved into a very good engine it is going to be hard to beat the IO-470. I still think the IO-470 is a more fuel efficient engine than the IO-550. The IO-550 rich of peak just likes to burn a lot of gas at a heavy power setting. LOP it does very well and that is where most will fly this engine. I hate to think of having the IO-550 with a carb and not being able to fly LOP. The IO-470 is also a lighter engine/prop combination and costs a little less money to install. All in all I still maintain the IO-470 is probably a better engine/airframe combination for the average owner and it's the engine Cessna should have installed in the C182 when new. It would have been easy as Cessna was already using this engine in their 210, 205, 310, C185, etc. At lower density altitudes the IO-550 has almost more power than you need. On the other hand for those operating from high density altitude airports, short strips or hauling a lot of weight the IO-550 is really nice. It all depends on where you fly, your needs and budget. With either engine you have a great airplane.

I don't see IO-550 upgrade/300se-stol/King Katmai pricing information yet on the PPP website...Todd?

In addition, if a 260se or Katmai-260 owner wanted to upgrade to the IO-550 at or near TBO, what would be the extra cost involved compared to replacing with another Gold Medallion IO-470 with prop?

Smile Are 182RG's eligible for engine and/or canard?

What a great XC machine that would be! Thanks.

No they are not. The Lyc 540 engine mount is incompatible with the canard design which was developed for TCM 470 series engines and works also with TCM 520 & 550 engines/mounts.

Air Plains has a Lyc 300 hp upgrade STC for the 182RG. It gives the 182RG C210-like performance. Not sure why it hasn't garnered more attention in the marketplace. Maybe because prospective customers just buy a used 210 with its 6 seats and great payload instead...

All that being said, I have always wondered why Cessna did not choose the IO-470 for the 182RG. That would have made a 160 KTAS cruiser and boosted ROC an extra 300-400 fpm. Not to mention getting rid of the carb ice thing.

We tried to keep the cost down for everyone that flies with our IO-470 when it came time to replace their engine. Everything certified for the IO-470 is reused for the IO-550 except for the firewall dishpan. The IO-550 got a little bigger firewall box that also includes the tach drive. Other than that nothing else need be changed. The fuel system, induction system, engine mount, controls, etc. are all reused for the IO-550. The cost of the firewall dishpan for the IO-550 runs around $350. Other than that the only cost differential is the additional cost of getting an IO-550 as opposed to an IO-470 and the same for the prop. I think all in all the addtional cost of the IO-550 installation runs around $15,000 over the cost of installing an IO-470. Not an insignificant amount but not a huge price penalty either.

Happy New Year All!!!

I have been flying for 20+ years and only recently become familiar with Mr Peterson and his design. I have been spending WAY too much time on this forum and on the 260se website. The videos are very informative. Hopefully 2012 will provide the opportunity for a visit to El Dorado.

Thank you both for your informative responses.

Cheers
Andrew
