3,000cc Corvair for Zenith 650

Builders,

Another engine on the break-in/run stand in my front yard. Photos taken Sunday morning, early this week it will be on the way to it’s home on the front of a Zenith.

Above, engine running on the stand. We break in the motor for 30 minutes with the rpm varying from 1800-2200. This takes care of mating the cam and the lifters. The run is done on Shell Rotella T4 oil with ZDDP added. Compared to many other motors, the Corvair is very easy to break in, as it almost never has an issue seating the rings very quickly.

Above, front view. Perfect 70 degree day with unlimited visibility in North Florida.  The engine is assembled with parts exclusively from FlyCorvair and SPA/Panther. Over the years, the stand has run hundreds of Corvair engines.

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.
