WW Corvair Engines For Sale
Completely Rebuilt And Test Run At Our Shop
Over the years, we’ve built more than 100 high quality production engines for builders who opted to buy the finished product from us. As a policy, every one of these engines are test run and broken in on our run stand. A review of our FlyCorvair.com and FlyCorvair.net Web sites will show photos of dozens of engines we’ve built that are now flying. Our great experience with Corvairs, our use of only the highest quality parts and the test runs have given us a spotless track record with production engines. This record makes it easy to stand behind engines we’ve built. These engines are fully remanufactured, and converted for aircraft duty. People who have selected our engines, installed them on their aircraft and operated them as we recommend have had to do no work other than regular oil changes and spark plug replacement at 200 hour intervals. The TBO on the engines is 1,500 hrs.
Many people who have selected a production engine still opt to attend the Colleges to get to know the inside of their Corvair engine. I encourage this because education has always been our primary work, and an educated Corvair pilot will be a better owner and operator.
We have three different displacements/HP ratings available. Below we have three examples, one of each engine. If you have further questions about your application, feel free to write or call.
All of the engines we build are completely overhauled and modified with state of the art components made in the USA. Every engine has a forged crank that has been Magnafluxed, stress relieved, ground, balanced, nitrided, polished and balanced. Our engines are built on the readily available Weseman 5th bearing. We have built a number of other engines using our own bearing and the one from Roy’s, and we will gladly speak with anyone about using either of these bearings. Our bearing or Roy’s add $1,000 to the price of an engine. There are other options like a Weseman billet crank, which adds about $1,500 to the cost of an engine. We are glad to include any proven option
The heads we use on our engines come from Mark at FalconMachine.net. I have been working with him for more than 10 years. His background as a Spartan-trained A&P mechanic, and a 32-year history of working with Corvairs led him to being the number one man in the world on cylinder heads for Corvair flight engines. He has worked directly with to fine tune every detail of head rebuilding and precision machining defines what state of the art is. Most of the successful flying Corvair powered planes today are utilizing his heads. Over the years he has produced more than 170 pairs of heads, and they enjoy a perfect track record.
Additionally, all of the engines have forged pistons, and the 2,850 and 3,000 have new cylinders. (The 2700 cylinders are re-bored GM originals.) They have forged rods with ARP bolts, harmonic balancers and high volume oil pumps. Each engine has dual ignition and electric start with a 22 amp alternator. The engines have our gold oil system and the builder’s choice of billet or welded oil pan. (Heavy duty oil cooling systems are a popular $600 option.) The only major component not included is the carburetor. While any of the engines can be used on airframes as different as a KR-2S to a Zenith 750, the carb must be a good match for the airframe. For example, aircraft with low wings and fuel pumps require MA-3 or Ellison carbs, while gravity feed airframes can use a wide array of carbs, including the affordable Stromberg. The Corvair has flown on more than 15 different carbs, and we will be glad to assist you in choosing the correct one for your airframe.
