KR> My corvair engine
I meet William Wynne tonight from flycorvair.com at a truckstop by his house. Him and I went though all my parts from my core that I bought from Steve Bray. Looks like I have a good start for a 3 liter, 3000cc engine except for the crankshaft which will need to be replaced. William said as of now the 3000cc is the way to go. I gave William most of the engine to start the machining and to cover the cores on the other parts. I will take the heads up to Madison Wi. for a head job. Hopefully by this time next year I have a aircraft engine. Paul Visk Belleville Il. 618-406-4705 Sent from my HTC on the Now Network from Sprint!

This would be a good book for anyone to add to your library to help you understand the finer points of engine machine work how to build to closer tolerences. I suspect it would be some good preparatory reading prior to the Corvair College. 20 bucks well spent. -- Glenn Martin KR2 N1333A Biloxi, MS, 39532 rep...@martekmississippi.com

The CorvAircraft list has several very reputable engine builder members who offer machine shop services, including head work, as well as complete engine builds. But why not build it yourself? The Corvair is an even simpler engine than a VW (if that's even imaginable) to rebuild. And William Wynne holds several "Corvair Colleges" across the country each year, where William, Mark "Petz", Roy Szarafinski, and several others are on hand to help wherever they can. People typically bring core engine parts cleaned up and ready to build, and one of the above folks will go over it with a fine tooth comb and dial indicators, etc to make sure the case and crank is suitable for aircraft use, and then assist when needed as you build your engine on the spot. These colleges have been completely free over the years, although in recent years there's been a small charge to cover meals and supplies. I think at the CC in November there were something like 11 engines run on the test stand for breakin. I've always had the attitude that if you want it done right, do it yourself, although notable exceptions are the three guys mentioned above. Having said that, it sure it easy to build a Corvair engine yourself, especially with William's conversion manual and the help you'd get at a Corvair College. That's something else you get from the CorvAircraft list, advice from some top notch machinists, as well as information regarding the whereabouts of the next College, for example. They are usually southeast, west coast, and midwest, spread throughout the year. Mark Langford ML at N56ML.com website www.n56ml.com

Well, since I am replacing the cyl and pistons anyway I figure why not go as big as possible without having to do any machine work. Right now the .060 over cylinders sold by Clark's would give me 2780cc and no block modifications so that's a no brainer but how much bigger can I go is the question.

Dyno models suggest 110hp can be obtained from the stock 2700cc WW conversion with OT10 cam at 3500-4000rpm with max torque below that around 3000-2500rpm. Question is can you spin your prop tips that fast..depends on diameter and ground clearance?? I don't think the extra effort/money you propose for 150cc increase is worth it. If you are going that way, why not go to 3100cc as Mark L has done but bear in mind there is a lot of expertise and care needed to do this.

I have been thinking more about using my '64 Corvair motor I purchased last year (looks to have all the correct #'s for a conversion). Actually I am now considering the AeroMax 100 IFB short-block, then add aftermarket 88mm VW cylinders and use my '64 heads after a rework by someone. Not sure if those heads will work. I am wanting a solid 110HP so I think I need to bring the motor up from 2700cc to 2850cc. Any insight would be appreciated. Craig www.kr2seafury.com
