RV-10 WITH Cool Power cylinders on a 0540

Planeless · Post by **Planeless** » Fri May 30, 2008 2:12 pm

Hi I picked Planeless for a name and I know there are a lot of us Pilots without a plane. After flying a lot of the single engine factory stuff I can see the appeal of the RV-10. I intend to build one myself. Like others I have given much consideration to engines. Without rehashing a lot that you guys already know, I am just wondering why I don't see much mentioned anywhere about the Cool Power cylinders, the liquid cooled conversion cylinders, for the Lycoming 0360 and 0540 engines. They seem like a great idea to me. Any comments?

Welcome to the group!! Glad to have you around

I don't really know much about those cylinder conversions. I wouldn't think that water cooled would be that beneficial unless you are running really hot. I am interested in hearing more.

seems like a great idea except for parasitic drag of radiators and the extra weight .. im sure the benefits are numerous but the whole complexity v/s simplicity thing would have me going aircooled cylinders in the end.

I hope I am doing this right. This forum is a new format to me.

I am back to considering these. Lets see what you all think. I have been around air cooled aircraft engines long enough to know that lots of them never made it close to the stated TBO. The cost of these cylinders doesn't seem too far out of reach when you consider all of the factors.

do you know of any installed in any rv's? id like to see some completed pics FWF. as well as some numbers. really does sound promising but weve seen promising.

ive got 21,450.00 in a new engine, maybe when it goes t/u i'll look into it some more. will you have a booth at osh?

The reason I started this thread was to find out the answers to your questions. I have never made it to Oshkosh, yet. I would think Cool Power had or would have a booth at Oshkosh, but I have no idea how big the company is. If their fuel economy claims can be substantiated in this time of high fuel costs, maybe their time is coming. I especially like the safety of eliminating the cabin heat from the exhaust manifold on air cooled engines.
Liquid cooled engines are better at dealing with the extra heat produced by turbo charging. I also would like to know if anyone has put one in a RV.
Years ago Continental developed a liquid cooled engine and they are still available but are expensive. The reports by people, in magazines, that re-engined their aircraft with them were very positive. I am really surprized that these Continentals haven't been used more in certified airplanes.

well maybe some of the guys going to osh this year will look out for "cool power" looks very neat, id like to see some in use on an rv. it is about the best concept ive seen yet if liquid cooling is what an individual is after.

Interesting! I haven't kept tabs on these guys for a while...didn't know they were still alive and kickin'! Not a bad price for the package if a good core is available...

When I get to the point of needing an engine, I would like to know if the crankcase and other parts like the improved camshaft parts etc. being produced today as copies of the certified engines for use in experimental aircraft can be used with the Cool Power cylinders. These kit engines have some features that are ahead of the certified engine's technology. I would want to assemble an "all new parts" engine. I never have the luck to stumble on something like a good used "core" to start with. I have been investigating this idea for a while now and I think the liquid cooled cylinders will provide more than a few advantages. When the time comes I will put my money where my mouth is on this. I have seen 0200s that were running at 2500 hours and 0320s can do fairly well also but I have heard about more than a few other air-cooled engines that needed a complete top overhaul by 700 to 1000 hours. Cool Power cylinders, in my humble opinion, should add a large measure of reliability also. I have flown over some very hostile landscapes and I don't want to see the prop stop if I can help it.
The fuel situation is making me consider an 0360 with cool power cylinders in a RV-7 now. I got my license in 1970 and some people though it was pretty expensive to fly then, but it was still possible to do it!, and easier to afford compared to what we have to pay out now.

I was intriqued by liguid cooling before I found Cool Power on the net. I did the research (a lot) to work out a practical conversion of automobile technology for aircraft use but it costs far more than I could afford to build. Forget that idea but in the process I became convinced about liquid cooling's advantages over air cooling. Air cooling works, I won't argue that for a second, but I really do believe that actual 3000 hours between overhauls along with hot coolant for cabin heat instead of heat from the exhaust manifold, less engine noise, and somewhat better fuel economy are real benefits of liquid cooling. So to me personally, it is not just a choice between air cooling and liquid cooling, I consider it all. I also think that properly designed and integrated into an airplane, the cooling drag from liquid cooling can be less than the drag of an air cooled engine. The P-51 demonstrated that. The RV-7 guy and his new project, the RV-10 with the Subaru SVX 3300 engine might well also prove the above. I am following his progress like a lot of others, I bet. There is one thing I am curious about. Dick Rutan had Cool Power cylinders on a 0360 in his Canard. (I don't remember the name because they don't interest me.) Now supposedly he took them off his engine and never said why. Cool Power probably asked him what the complaint was but he didn't or wouldn't say. If anyone knows him or sees him at Oshkosh this is a question I would be very curious about. I don't think I will be able make it to Oshkosh this year either. I am going to email Cool Power and ask if they will be at Oshkosh, I will report on their reply.
Today is 7-10-08, I did email Cool Power, they nust be too busy to reply?
