Corvair engines need no introductions. These are some of the most converted car engines used in aviation. Auto conversions or basically car engines converted to aircraft engines. With fly corvair, they are using corvair engines which a re readily available (over 60,000 produced). And then coverted with new parts to meet high altitudes flying.

The comments about this engine are unbelievable; this guy has produced a reliable and well thought out conversion that has stood the test of time. Comments like flying behind a 40 year old scrap engine, your continental, lycoming engines are not State of the art but they are proven technology like this conversion. I have personally witnessed the dedication that Wayne provided at his seminars, it is always safety first with him I've never seen him try to sell anything he didn't believe in 100%. Before making offhanded comment look into what this person is actually done and provides to the aviation community.

Very well said Don, I agree with you

[@peteranderson037]

I guess those people don't understand that the Lycoming O-320 in the 40 year old Cessna 172N that they rent from the local flying school is just as old and just as worked over as the Corvair engine in this video.

[@MrPaige222]

That, and the people who charge 50, 000 dollars for an engine that probably costs 5 grand to overhaul.

[@jackburnell3209]

From the time I was a little kid I dreamed of flying. In high school a friends dad took him and I up in a little single engine plane. I was a little surprised at how lightweight and rickety it was. When he flew us what seemed to be straight up then killed the engine and pretended to panic before restarting it and laughing like a madman...that cured me of ever wanting to fly again. Not for any fear of the plane, but because I found out that you could be insane and still get a pilots license. I didn't tell my parents about it for years.

[@donaldblankenship8057]

It appears gorgeous. There is one obvious fly in the ointment: Instead of seeing an electronic igntion, or one magnito or two, it uses a car distibuter. That doesn't really save any cash up front to lower the initial cost, because many electronic ignitions are available. The FAA would look with a jaundiced eye at using a distributor. Aircraft labeled Experimental I think have much greater advantages and satisfaction if they fly well and not kill anything other than grass and themselves. But electronic ignitions are the only way to go. The car distributor on that engine cost $150 - $250 and are imfamously unreliable. Electronic ignitions cost about the same but are much more reliable.

[@oldowl4290]

Some guys are still using Subaru 4 and 6 cylinder boxer engines with their experimentals. Personally I think they are fantastic conversions and like any they have pros and cons. There are of course naysayers who feel they've not been refined enough or been around long enough to be "proven" but I also think that's subjective to who has done deep homework to make them a long term success.

[@meninactionllc5869]

does this company also do certified aircraft ?? do they plan to ?? thank Mike for posting this

[@DanFrederiksen]

I'm generally not a fan of old but it looks nicely compact if that is everything. Is it computer ignition? carbureted? could it be turboed?

[@playerpage]

The Corvair was the first American car sold to the public with a turbo. You can turbo the engine.

[@MrSUPERISIS]

You would probably like to study "INNengine" engines.

[@bryantturner97]

I'm thinking a Saab engine might fit the bill. P.S. Did Paul Giamatti dub this guy's lines?

[@DCGULL01]

I wonder if this would work on a Sonex? I'm unsure if it is too heavy for this smaller, lighter craft, but- if it does (mounted closer to firewall for better CoG?) it would be another solution for that particular group of craft. I know that if it drops a cylinder- it remains smooth, but- I think weight would be the primary issue.

[@ik04]

Yes. It has been done. Look up Cleanex.

[@Shmey]

In Waco, Tx, there is a retired A-4 pilot with one of these in his Sonex.

[@donaldblankenship8057]

The Sonex is in the micro category. That engine is way to big. At leasr one KR-2 builder put in a Corvair engine. For the added hp, I would like it. The KR-2 could put any engine on the front that had at least 48 hp up to 200 hp. The standard Beatle engine puts out 55 hp. That's basically what you were going to fly at above 135 mph to commonly 155 mph. At altitude of 10,000 feet, drag is reduced, and not counting tail winds could show 155 mph on the indicator. GPS at 10,000 feet with a 40 mile tail wind, you could be tim e traveling and pass your destination.

[@captarmour]

beautiful engines! intake and exhaust plumbing look pretty restrictive. any performance upgrades in intake and exhaust manifolds? any turbo or supercharger options for better performance at altitude?

[@jasonhughey4434]

I'm sure you can you can use all the car performance parts. I have this motor in a sand rail that is 172hp to the rear wheels standard upgrades aftermarket Intake carb higher ratio roller rockers higher compression and you can go to a stroker crank an oversized jugs and pistons that can give you up to 3.3 litre.

[@johnsalem7765]

How does he reduce RPM ?

[@LaHayeSaint]

I'm waiting to start my PPL as soon as funds permit. However, this is my first knowledge of car engines being used to power an airplane.

[@tomdchi12]

The key thing here is that these auto conversion engines are essentially only allowed in aircraft that are in the "experimental" category, not in the "certified" category. (That said, there are certified conversions like those used in Diamond aircraft that were originally Mercedes diesel car engines that have been significantly modified but the company went through the process of obtaining official FAA and European certification for the engines and the aircraft they are used on.) This is at Oshkosh, which is hosted by the EAA - the Experimental Aircraft Association.

[@LaHayeSaint]

@@tomdchi12 Thomas -- if and when these auto engines are certified, these engines could become extremely popular in planes. But until this arises, there will be headwinds such as use in experimental planes only. Pilots are likely to shun these engines until such a time comes about. However, thank you for your response.

[@ubermenschen3636]

Install newer tech such as electronic ignition and fuel injection in lieu of distributor, contact point and rotor, and carburetor. Electronic engine timing and variable valve timing control will also also help. Turbo would be awesome.

[@GeneralSirDouglasMcA]

Azalea Aviation (in Quitman Ga) produces a Turbocharged Corvair engine (120 hp).

[@crazyc99]

What's the max hp you can squeeze out of the 3.3?

[@tpspc03]

I believe 120HP is the largest they currently have

[@ChasOnErie]

Hmmmmm…I DONT think so … I had a Corvair … a couple !!!! I could coast to the curb and put the van belt back on … that would be tough at 10,000 feet !!!!!

[@thisismagacountry1318]

Since the Toyota V6 is so smooth and reliable would that work well?

[@williamparker917]

Viking engine that was mentioned in the video uses Honda car engines. You would have to see what the weight to power ratio is, and make sure the air craft it's put on can handle it weight. Like he said in the video conversions have a bad rep. for this reason people just try what that can without doing the research and testing.

[@mombasasherman]

The 1GR FE V6 would make for a very good conversion... Good point Parker

[@chriswalton720]

A major issue with newer V6 engines is that most of them are fairly tall and narrow to fit sideways in a front wheel drive engine compartment. This shape is not optimal for most aircraft cowlings. It fits better if you turn it upside down, but now your oiling system just got much more complicated.

[@weofnjieofing]

The problem is the weight, cooling system and reduction gearbox you will need to slow the prop speed to about 2600 rpm. The corvair option does away with all that leaving you a smooth, direct drive, simple and reliable installation that you will understand inside and out as you actually build the engine yourself (though you can buy completed units).

i have just few hrs in cessna s (single engine) as student pilot long back. i still keep browsing about tiny planes in GA sector. i am wondering if any experts here can clarify few doubts i have: - considering himalayan/ tibetan mountain ranges and their weather patterns, is it possible to design a piston-engine (normal petrol), single-place aircraft, with about a ceiling of 35,000 ft? - can the same aircraft be STOL & fuel efficient at low altitudes for cross country flying/ long trips? thanks in advance.

[@Shmey]

There are very few piston engine aircraft that can even reach 35,000. For anything with a practical mission, you would be looking at a TBM or better. Price of entry is about 2-4million. For a Corvair engine, I wouldn't expect to spend much time above 10,000 ft, though I think the engine is amazing.

[@prasadjonnalagedda8633]

@@Shmey thanks for the info. i am only wondering, why there aren’t any piston aircraft designs available in these modern days, especially 1 or 2 seated for high altitudes!

[@Shmey]

@@prasadjonnalagedda8633 I don't know much about regulations anywhere but the U.S. Here, the simple answer is cost. To legally fly at higher altitudes, the instruments (typically an encoder tied to the transponder) must be certified to the altitude you want to fly to. Higher altitude flight requires a longer test. A longer test means more shop time. More shop time means a higher cost. I can't remember the regs off the top of my head, but I think the requirement is 24 months, so it's not a one and done deal. The good news is 35k feet seems a bit higher than necessary. I have no idea what your mission is. I'm guessing, as a low-time student pilot, you can find a plane to fit your mission. As long as you have an accessible airport that a small plane can take off from, you should have no trouble getting started. Flying to 35k feet might have to wait a bit, but you'll get there.

[@prasadjonnalagedda8633]

@@Shmey oh no, my few hrs were like two decades ago, and i am 55 now. not sure if i take the training again, but curiosity makes me sometimes to lookup at the flights and browse internet regarding them. with these recent isolations around the world, i started wondering if a cheap certified aircraft is available, it maybe nice for some middle class individuals, who are willing to own & fly them privately. because there is lot of traffic between india & nepal, and also for accessing remote communities living in mountain regions across the country- i became curious about high altitude tiny aircrafts. also, i guess, most of the governments around the world won’t be happy with individuals flying at high altitudes. anyways, thanks again for your feedback, as i am trying to educate myself a little bit regarding, if many requirements can really fit in one machine.

[@pebutts]

@@prasadjonnalagedda8633 Several issues with flying at that altitude that pretty much eliminate small inexpensive aircraft doing it. The most important are the need for cabin pressurization and the problems with operating a propeller aircraft in air that thin. You can't fly at 35,000 feet without a pressurized cabin. Those aren't cheap and designing a small aircraft that can be pressurized isn't easy or cheap. The Piper M350 is about the least expensive thing on the market that I'm aware of and it starts at $1.15 million. It's only rated to a 25,000 ft service ceiling though, so you'd have to put out a lot more cash to get into something that can operate at FL350. You're looking at a jet and that's way out of reach for middle class people.

[@DrJoeHandsome]

I don't think the corvair is an easy project. Two many options, you have to be a dumpster diver to find the core, then you have to figure out what you want order/build. Or go to viking or aeromomentum get the same hp engine for the same price built for you.

[@kleinbottled79]

Did you really listen to what was being said here though? They will sell you a completed Corvair motor if that's what you want; and it doesn't even really save you that much money to build it yourself. However, he encourages people to be involved in the build process so they intimately know the motor and can therefore be a better operator/maintainer. If that whole concept doesn't appeal to you, yeah, probably work with someone else. It's right up my alley though. DIY life!

[@DrJoeHandsome]

@@kleinbottled79 true he does offer complete engines for around 1k less. There is a reason corvair isn't as popular IMO. I was going the corvair route and found myself overwhelmed with the offerings and reasoning behind everything... Then there is the corvair college.. Not an easy or moderately easy endeavor. The engine is proven, but.. There are newer and engines at a better price point.
