Aside from the precious dollars spent on the book, you WILL need the GM factory manual and likely the videos that the author offers. I have purchased and read W Wynnes book and found fully one half of it written in the first person, boasting of his abilities and full of references to unrelated and incidental bits of aviation history. Do not expect to convert/restore an engine with this book. The book does have about 5 paragraphs that are definitely useful,...so borrow a friends book or have a bunch of you purchase one copy and share..OR.. read these KR net newslletters. All of the useful information from Wynnes book is or has been mentioned several times over in this, our forum.<<
Obviously, I strongly disagree. The reason I wrote "For those planning on using a Corvair engine, the very first step is to buy William Wynne's Corvair Conversion Manual" is because it makes a lot of sense and will pay for itself sooner or later, and perhaps may save your airplane or your life. In the case of the guy trying to sell the 80 hp Corvair engine, it would have saved him from having bought the wrong engine core to start with. I'm guessing he paid at least 3x what he would have paid for William's manual. And another piece of advice mentioned early in the manual is to buy the 1965 GM Manual reproduction for all of the mundane engine building details. Why would William waste time and paper reproducing that info in his manual, when the best source is already in production and for sale for $23? Yes, you can spend the next three months reading the KRnet archives for morsels of info on building a successful Corvair engine for your KR and still not find it all (or worse, find disinformation written by those who are clueless), or you can simply write a check for $59 and read it all over the period of several hours, in a well organized and informative package that puts it all together in one place. And don't forget where 99.9% of the info in the archives came from....William Wynne's efforts. And yes, you can have a machinist make a prop hub for you, but I'm pretty sure it'll cost you more to have one made than you could buy one from William. It makes a lot of sense to take advantage of the economy of scale that CNC allows, not to mention buying flight proven parts that you know will fit the first time and match up with the rest of your installation. That aside, I think it's worth mentioning that almost certainly, we wouldn't even be talking about Corvair engines were it not for William Wynne. The Corvair engine in aircraft applications was dead and forgotten when William picked up the torch and literally made the engine work for aviation use. He's devoted his life to this endeavor for the last twenty years, and I think most of us can agree that it's just not right to "borrow a friend's book". If somebody thinks they can reproduce William's twenty years of work all by themselves without referring to anything he's done in the effort, and do it for less than the equivalent of $59, I wish them luck...
