Mike, I bet Mr. Wynn probably really does think that the Corvair is better than the Continental - He's in the Corvair business ;-) Seriously though, I think I know what Del means, for the money, the Corvair is probably pretty good. Would I rather be sitting behind and O-200? You bet! I had a 150 for several years, one stuck exhaust valve in about 400 hours of operation, a little Marvel and a wooden mallet and I was back in business! I got another 150 hours before I sold the thing - no more problems. But as a low-budget play aircraft, I am leaning strongly toward the Corvair. I like the price, pretty good power/weight, and I like that Bernie tried it! I don't like the ignition too much, or the bass-ackwards direction of prop rotation, or the sound, but it'll be fun! I may opt out for a A65/C85-90 in the end - who knows. Boy, I bet an O-200 in the Piet is a hoot! Did you keep the electricals, or pare it down to the basics and hand prop? I like the idea of no electricals - I want to keep it CHEAP! Living near Houston Class B, I don't want all the transponder stuff and all. Just a hand-held. I bet that Piet of yours is impressive!Gary Meadows________________________________________________________________________________

Del, he lied to you about the Corvair being a better engine than theContinental. In order to get a Continental to develope 65 horse poweryou have to turn the engine at a higher RPM which means a smaller propand more wear. There is more weight and you need lots of special partsto get everything to work. I'll take an aircraft engine any time. Asfar as parts, I can't think of a single item that can't be found for theContinental. The cost will be less in the long run too.Copinfo(at)ix.Netcom.ComTim CunninghamDes Moines, Iowa (515) 237-1510 Del wrote: mr wynn thinks that the corvair is the better engine anyway. >> ________________________________________________________________________________

Just a comment on Corvairs.I had a 1969 Monza convertible with a four speed box. Bought it in 1975 with 39,000 on the original engine. I didn't baby it. Sold it in 1988 with 110,000 on the clock. Had to replace the serpentine belt twice and the oil pan gasket once. Around 80,000 I thought about pulling and rebuilding the engine but couldn't justify it as it was running so well. The Continental A-75-8 in my J-5 was balanced and zero timed in 1975. Even with fine tuned "Eyebrows" (cooling ducts a la J-3) the right rear ran chronically hot. Cross compression check at 1200 TSO required a replacement right rear jug. Another 1200 and it needed a ring job. During periods of high humidity the Cont. was hard starting (no impulse mag) and no stranger to carb ice (just like my '65 VW). The 'vair started easily every time and never iced up.I would have absolutely no compunctions about using a Corvair engine in an aircraft.....On the other hand side ... as a bona fide bear for punishment - I am currently rebuilding a 1929 Henderson - Heath engine, looking for an "A" for the Sky Scout under construction and have a line on a three cylinder Anzani and an Aeronca (Franklin?) E-113 (two cylinder) stored in a barn in New England.DG________________________________________________________________________________

You must have mistyped the horsepower also, as youtyped 65 hp. where as the corvair is actually 100hpmaking the hp per weight ratio much moreattractive.also keeping the prop smaller has itsadvantages too.---Copinfo wrote:>> > -Terry- You're right.

Del, Come to Des Moines and I'll be happy to give you a ride in a Piet. Istill have to go to Broadhead and I might do that this weekend if you want aride there. Heck, I'll fly to your house if you have 1000 feet to land on.The Corvair is 110 hp at 3800 rpm. The prop I had on my Corvair was a Hegy66 X 60. You need a smaller prop to get the full rpm to develope 110 hp.What you end up with after all the math is done is an effective 65 hpengine. The problem is you have the extra weight and still have to run at ahigh rpm. I think Don Pietenpol or Vitalis Kapler may have a booklet thatexplains the plus and minus' of the Corvair. They do run smooth and soundgood but they're not for me. I sold mine with the prop for a $1000.00 andbought a Continental. Love it.>You must have mistyped the horsepower also, as you>typed 65 hp. where as the corvair is actually 100hp>making the hp per weight ratio much more>attractive.also keeping the prop smaller has its>advantages too.________________________________________________________________________________

Hey Copinfo, I went to the Corvair engine-mod website that Del is talking about. This fellow, William Wynne maybe it is, has both Del and myself all excited cause he claims to be getting 100HP out of the Corvair at 3200 rpm! He has a different cam he sells for $299, but I'm starting to wonder about it - hard to believe a cam could change the power curve that much. I wonder if anyone out there has tried these mods on a Corvair engine in their Piet? Well, here is what he says:HP...........................100@3200 rpmHP (Continuous)...............90@3000 rpmTorque............. 160 ft/lbs. @2800 rpmI like the Continentals a lot, but this being a scroungers type airplane, I guess I'm kind of caught up in this mode, and don't want to go to a certificated engine. That don't mean I won't, but I just don't want to.Still in all wouldn't a Corvair still give better performance than the Ford "A"?________________________________________________________________________________

The Model A people will probably tell you thesame. I've seen a lot of Corvairs and Model A's parked along the roadduring their hey days and I wouldn't go in the air with either. I guaranteea cam difference is not going to give that kind of improvement in horsepower at 3200 rpm. I'd check with someone who isn't selling something. Howmany hours does he have in the air at 3200 rpm with that engine? I knowwhat it's like to try to save money but the engine is a good place tosplurge.Good LuckCopinfo(at)ix.Netcom.ComTim CunninghamDes Moines, Iowa (515) 237-1510________________________________________________________________________________

Although not a Corvair, I was quite suprised when I drove my parents'Subaru Loyale automatic. It was complete with a tach. At 110 kph (65 mph)the engine turned at 4100 rpm. This was also the rpm that the aviationversion turned at cruise. Remember, a lot of these smaller, low poweredengines turn a lot faster than the old V8's.KenOn Thu, 9 Sep 1999, Copinfo wrote:> Gary Wrote:> power at 3200 rpm.

One more thing about the corvair: Torque is 160 @ 2800, AND, puts out 85.6 hp at this setting. Without any special cam! This is the 110 engine. Ryder________________________________________________________________________________

Tim, This has been an interesting discussion about the engines and all. I'm sorta glad that I have some time to work this whole engine thing, before I have to make a decision. The one thing I'm sure of is that it will be an air-cooled something or other, so I can build the plane up a lot before that big hurdle needs to be jumped. My finance department has a requirement that I have something to put the engine on before I really start a serious powerplant search. I think I'd better listen to her on this one, and put a plane where my mouth is! Thanks to everyone for the input!Gary________________________________________________________________________________

Also,Wynn doesn't push any product except for the knowledge that he hasaccumulated. If you get his manual, he lists the least expensive parts thatare high quality that are available and the source. The cam that he recommendsin his manual is not his own but is the least expensive available from regularCorvair parts sources. He has a dynamometer to test his ideas on. He is ofcourse biased towards Corvair power, it's what he works on all the time, but heis also quick to point out the shortcomings of the engine. I feel good aboutthe $49 that I invested for his manual and expect to get many times the valuereturned. I am now, also, biased towards Corvair power to fly with. What Iwant to get across is not whether to go with a Continental, A or Corvair, butthat I get good "vibes" about the guy. I think that he is a reliable sourceof information. I am impressed with the knowledge that he has to offer. Ialso plan to go to him for a prop hub. The one he had with him at Brodheadwas really fine quality workmanship.That's my "soapbox" for this month.Mike BellColumbia, SCMaiser(at)adena.byu.edu on 09/09/99 09:31:55 PMPlease respond to piet(at)byu.edu @ INTERNETcc:Subject: Pietenpol-List: Re: corvair/continentalOne more thing about the corvair: Torque is 160 @ 2800, AND, puts out 85.6hp at this setting.

>I am also very impressed with Mr. Wynne. Although I would have liked a note on his answering machine that he was temp. unavailable a few months back so I wouldn't have call every few days... He has been extremely helpful to me. Calmed me when I got excited about a difficulty. $49 is a bargain. Although I have to sell my engine I am not selling it with the manual. I am going through a divorce and must sell it because I am poor but I plan to start the next one as soon as possible. I too am sold on the Corvair. It is a brand new engine when it is done. I feel more comfortable with a engine that I know inside and out and have dealt with any difficulties and understand it. I really enjoy the process. I remember two years ago when I first got the Corvair, 1967 110HP. I had a ball dissassembling the engines. I had no clue. I have learned a great deal and I owe alot of that knowledge to Mr. Wynne.If any one is interested in the engine let me know;110 HP, SS top studs ($125), block assembled with crank and cam from Wm. Wynne($450 with bell housing cut and shaped), new main and rod bearings($110), new pistons,rings and .03 cylinders with reconditioned rods($700), heads have a valve job and new valves and springs ($325). These are the prices I paid. I am looking for best offer. I also have many cores and misc. parts.William Koucky________________________________________________________________________________
