But in short, the answer is: William has converted the engine to make it's peak horsepower, about 110 h.p., at around 3100 rpm which is about where us aircraft guys want to run things. He has done this with a couple of modifications: 1 - remove the blower fan (we've got one already installed at the front of the plane), 2 - advance the timing (lots more discussion on the web site and in the conversion manual, 3 - install a different cam (OT-10) I realize I have given an answer that is WAY to brief for this topic. Also, you really should consider getting on the Corvaircraft email discussion list. This has been hashed about and beaten to death there. Check the Zenith List (this list) archives and you'll find the link to that list as well as a lot of Corvair information there also.

I also followed your link and read (well, scanned) the "Why Fly Corvair" page for more information. It left me wondering why anyone would put one in either a CH 601 or CH 701. I say that because of the high engine weight. I think both planes call for a max firewall forward weight of 200 pounds and the Corvair seems to start at 205 without little extras like a starter. (I suppose my memory could be playing tricks on me here - I am often wrong about simple facts like this one.) I am glad to hear there is at least one auto conversion that doesn't require a reduction unit. I will (try to) update my memory on that point. The only other initial reaction I had was the fact that the engine turns "Backwards". I realize it is possible to learn to stand on the other rudder pedal, but after some 40 years of flying the other way I am not sure my old bones would ever quite get that one. I guess I am still pointing toward using a Jabiru 3300 in my XL, but there is still about a year before I will actually order any engine. I am open to any ideas to consider.

Thanks Brandon and Dave, I looked for information about FWF weight and found very little. The ZAC web site mentions 300 max for the XL. I couldn't find any limits in the drawings or construction manual. I guess this is one of those areas where "Old wives tales" rule rather than actual specifications. If there were a real limit I would think it would show up on the second page of the official drawings. Having some numbers on a web page is fine, but web pages have been known to change over time. I did see 200 pound limits mentioned on the "Why Fly Corvair" page for both the Sonex and 701. I must have imagined the 200 pound limit for the 601 XL.

In the airplane we only want about 100-110hp. The fact that it is being run at a point MUCH lower than it's AUTO design value is one of the things that makes the Corvair engine such a great engine for the 601. You are right about most ato conversions. if they have to run at 5000rpm you are going to have to have a reduction system. You really ought to visit William Wynnes web site http://www.flycorvair.com --> Zenith-List message posted by: Paul Mulwitz OK, I'll be the first to admit I know very little about the Corvair engine (except it is the only car engine I have ever burned up - broke the fan belt while driving a real Corvair). My thinking was that most auto engines build power to a peak around 5000 RPM but most propellers work best around 2600 RPM. I was under the impression that to get maximum power out of any auto engine you needed to reduce the engine RPM to get an idea prop RPM. Where did I go wrong? Isn't it customary to install a reduction unit on any engine other than a purpose built aircraft engine?

Also, I guess I saved about $10,000. I'm not flying yet, but my engine is installed. I have flown in William Wynne's plane and it is very nice. Probably one of the best performing XLs around. Also, he and his crew are some of the nicest people in aviation -- bar none. I've visited his hangar 3 times now, and I've learned more from him and his crew than anyone.

I was fortunate a couple weeks ago. Gus Warren was at Pontiac Mi just after Oshkosh and he graciously took me for an introductory flight in the WW ZenVair. This was my first flight experience in this aircraft. Since mine will be very similar, I have no doubt this combination of airframe and engine will meet all of my expectations. The view was excellent, seating is comfortable, the performance was very good on a hot day with two plus sized passengers, the engine was very smooth and it sounds good too. Although I will need more time to learn to fly it with precision, it is an easy aircraft to fly.

But, as last year, the weather in the midwest prevented me from making the trip to Mexico for the factory flyin. So, yesterday I took my longest flight. Seattle to Yakima to Walla Walla to Portland to Seattle. I put 6.1 hours on the hobbs. In Walla Walla, I asked a local about the updraft turbulance and the dust devils that were rising around the airport. 'Welcome to Eastern Washington' I was told. The fire fighting helicopters that were buzzing about at Walla Walla threatened to blow the canopy off - so I closed it. It was a great flight, down the Columbia river. I cruised at 2300 rpm to keep the oil temp at 220F. At 5500+- ft I was comfortable. When I decended to land the inside temp went up and I started sweating. Putting a pen under the canopy lip on both sides made it acceptable. I spent today digging fence post holes at the NWEEA Arlington barn. They're putting up a fence to protect the flyin equipment. Then I took two EAA volunteers for a ride. After that I took up Gary who is on the verge of flying his SeaRay. He is using a Jabiru 3300. He had a great time seeing what 633Z will do. I had a great time flying the past two days! Joe E N633Z @ BFI 252 hours Jabiru 3300, Sensenich 64x49 wood prop P.S. I exaggerated. My canopy latch has to be be pulled in 0.5" on the right side, not 1". 1" may be too much. It fit exactly whne finished but has moved over time. Maybe I'll make the Hartl modification - it looks good. do not archive
