Corvair Aircraft Engines - ENGINE WEEK 2024

[@tomcoryell]

I like this gentleman’s attitude. I’ve been a mechanic (non-aircraft) for 43 years. The simplicity and proven reliability of these engines should be taken note of. Fewer moving parts means fewer areas of failure.

[@cptzoom]

Great video!! As a DAR I have certified several planes with William’s engines on them. I’ve been very impressed with them.

[@avmechllc]

I was fortunate enough to fly Williams Pietenpol back in 1999-2000. This was in his early years of corvair conversions. The engine ran flawlessly all the way to Oshkosh and back to Florida. I also flew it to the Kansas City area and back with zero issues. Now, all these years later, his product has improved by orders of magnitude and ranks among the very best engine options in the mid 100 hp range. There is no one on this planet the remotely comes close to the depth of knowledge that William has about these engines. If you follow his instructions, you will have a great, reliable and well running engine.

50 years in aviation (A&P/IA, EAA member), started working on Corvairs about 60 years ago (wish I still had at least one), I love what William is doing with these engines. Hopefully make it to Sun and Fun next year and meet up with him 👍

[@GaryBoothe]

Great job! My William Wynne Corvair powered Pietenpol has been flying for over 10 years!

[@BillyStewart-r9d]

I have a Zenith 601XLB and I've run both the 2.7L and later the 3.3L engines. I installed them according to William's installation manual and both were great trouble-free engines. I'm up to around 400 hours on the plane now.

[@steve2736]

30:06 Absolutely positively true. His knowledge and experience are irreplaceable.

[@SmokinJoesAdventuring]

The Corvair is a proven engine and William Wynn's knowledge of its adaptation to aircraft use is invaluable.

[@travisbouton4056]

Now I really wanna go learn about those engines. From that guy. I remember shop class. Work with my hands. So chose family over being moneyed. Lol. They did built thing better back than. Thanks.

[@scottmiller4711]

Very informative video...

[@PghGameFix]

Been waiting for this one !!

[@gokartmozart1567]

I have a corvair engine in my building ready to be converted :)

[@scoot77777]

Very nicely done✅😊🇺🇸 Thank you 🙏

[@Rio_Seco]

Great option for airplanes that fly on 100hp. A lot to like about a carbureted smooth running 6 cylinder boxer, with a very long history in aviation.

[@ddok172]

The reason I chose the WW Corvair flight engine is because of WW culture of no nonsense safety. Oh, and they sound awesome too!

[@dgardea11]

Great video Bryan! I love my 2700 Corvair that I built using William’s excellent manuals and his high quality components. It has over 660 hours in my Zenith CH650, runs beautifully, and provides great performance. One day when this retiree needs another project I’ll likely upgrade it to the 2850.

[@timk3225]

Love my Corvair power .. had a 2700 .. the original builder put 250 hr's on it the 10 years he owned it ..... I've had mine for 3 years and have put 350 trouble free, non oil burning or oil leaking hours on it ... I have recently swapped that motor ... for a 3L built for me by William.. not because there was anything wrong with the 2.7L .. but cause I had " the need for speeeeeeed" .. picked up about 12-15 knts with the swap .. cant say enough good things about it .. I use mine as a taxi from N of Boston to the Jersey shore 2-3 times a month .. down the Hudson river route .. or over JFK .. actually looking for a KR2 or similar slippery airframe to put another corvair into (love my zenith ... but its a cinderblock as far as aerodynamics)

[@davejohnson7678]

Right on Rudebaega.

[@jiyushugi1085]

Honda Superhawk! 305 Dream rider here.

[@captarmour]

Great video! Any turbocharged Corvairs? How much boost can they take before destruction?

[@Joe_Leising]

It is my understanding that development of a turbo system is part of the driving force behind the demonstrator airframe

[@brianl7695]

Please do AeroMomentum next.

[@jiyushugi1085]

NGK CR9NEK is a tiny 10mm plug that can be used for dual-plug setups where space is an issue. These plugs were widely used by Japan's gamble racers in their highly tuned Triumph motorcycle engines.

[@zenvairpilot]

No need on this engine. I have been flying mine for over 400 hours. It does have a dual ignition system just not dual plugs. The plugs are resistant to lead fouling due to a large gap in the electrode and a very high voltage spark as compared to magneto systems.

[@oltimer5544]

Is that a Honda 300 Super Hawk from the mid-sixties parked in the background? I was in high school in the early/mid-sixties when the Honda craze hit ("Go little Honda, Go little Honda, you meet the nicest people on a Honda!"). Me and all my high school buddies bought Honda bikes and road all over the streets of Raleigh< NC. I had a Super 90, then a CB 160, and then a CL 450. The Super Hawk was the top of the line early on before the the CB 350's came out.

[@Антоха-ь2к]

👏👏👏👏👍👍

[@crawford323]

What about a power take off to spin a pre- rotator for gyro planes?

[@djal1030]

waiting to see the Aeromomentum. Specifically the AeroMomentum AM15 HP that claims 147hp.

[@stevenwarner7348]

A hem.... Errrr.... I have a Suzuki Bandit. 1998 1200. Maybe this guy would be willing to comment on motorcycles? Hmmm? Course with that one carburetor no syncing needed. Gonna take on those four carburetors this winter. Oh well. An engine is an engine is an engine. But all this is such an inspiration. Wow. Just Great! Thanks so much for this. Those pipe welds. Woooo Weee.

[@joseeduardo998]

If it wasn't too much to ask, create a channel in Portuguese. Use AI to do the dubbing!

[@jpdurr]

While it may be against Mr. Wynne's advice, there are many who would like an EFI / FADEC option for this great engine. It's 2025. It can and should be done. I say only as an OPTION for those who want it. Nobody would be required to buy it or use it.

[@zenvairpilot]

not worth the complexity. the value of the engine is in its simplicity.

[@jpdurr]

@@zenvairpilot Not worth it to me without FADEC. To each his own. I said to make it an OPTION. I would value it with that OPTION.

[@sjsz06]

Blah.blah,blah…. Quit talking and show us the plane, or engine.

[@brentdykgraaf184]

Corsair. Have mixed emotions. Corvairs leak. Always have. Can make good power.. leaks were normal in the 60,s. Had to put my restoration 1966 corsair monza convertible . Dual ig ition would make me feel better. New seal materials would be better. Than cork.

[@lesizmor9079]

You are correct that Corvair engines all leaked. But it appears that you don't know details, and details are how problems get fixed. It was the push rod tube ends that leaked, and that problem was fixed by Corvair rebuilders long ago. Are you thinking this guy has had a steady business for 35 years from selling engines that leak in 6 months?

[@zenvairpilot]

I've been flying mine for almost 7 years. I don't have any issues with the leaks. It does have a dual ignition built into the distributor. There is a electronic ignition module and a points set up. They are easily swapped inflight by using a coil changer and 2 ignition coils. The points are retarded 2 degrees from the electronic module making starting easier, and in case of detonation a simple way to stop it. They only use one plug per cylinder, but the high voltage of the spark minimizes lead fowling. Been a great engine to fly behind.

[@vr6chrisvw]

I recently flew my Corvair powered airplane 12.1 hours in one day from Illinios back home to California. You know what I wasn't thinking about when I was flying over the Rocky mountains? The answer is oil, because if you build it right, it doesn't leak or consume any.

[@GaryBoothe]

You’re living in the past!

[@flyguyeddy]

It HAS dual ignition.

[@brentdykgraaf184]

Rotek....oh my.... quality?.. understood standardization?. Rotec nothing..logging off.

[@douglasrobbins856]

probably best you logged off, you already know more than the guy that's been doing it 35 years so it's unlikely you could learn anything.

[@zenvairpilot]

The carb is a perfectly airworthy product. I have a Marvel Schebler MA3-SPA on mine right now but will be changing over to the Rotec. Less moving parts. Fewer failure modes. The MA3-SPA is a great carb, but I prefer the simplicity of the ROTEC moving forward.

[@Wingwalker77]

I mean, if you already know everything, why were you logged on to begin with?

[@brentdykgraaf184]

@Wingwalker77 wow...sorry you feel so.
