Take my airplane, for instance...a Bowers Fly Baby, built by someone else. It has a dead-stock Continental C-85 powerplant system. System, not merely an engine. Everything forward of the firewall could be unbolted and transferred directly to a typical high-wing Piper. Heck, I think everything FWF on my plane but the duct tape is right from the Piper parts book. :-) I believe you will find that particular part number in the Alaskan supplement to the Piper parts book, right next to the copper RTV anti- chafe compound. ---------------------------------------------------- Del Rawlins- Remove _kills_spammers_ to reply via email.

... "Treefrog" wrote in message ... "Barnyard BOb --" wrote in message ... What's so funny about a Soob in a plane? I don't know. What? I do know.... the last Soob powered local plane crashed, burned and the pilot became another fatality statistic off the end of runway. Maiden flight Propulsion issues. I don't know what kind of crap you get sold in the states but over here (UK), the standard 2.0l turbo Subaru engine kicks out 208Bhp and is very very very very very reliable. You could prop hang an ultralight with that much power! I am as much pro auto conversion as any person in this group. You are DREAMING if you think you can rate a 2 liter Soob for 208 HP continuous output. You are running how many RPM, and how many inches boost to get that figure? No sane person would run a motor that hard, and depend on it for hour after hour. Give me the figures. RPM and amount of boost. -- Jim in NC Oops, my figures were out slightly. The new model produces a little bit more than 208bhp. Ok, it ain't going to last at continuous redline but the power is there for short bursts, e.g. takeoff. This is the engine specs straight from the factory, I can't find any information about stock boost pressure. 265bhp @ 6000 It has been known for these engines to be tuned to well over 500bhp (in fact, I know of an 800bhp Subaru). Obviously you would never run that in an aircraft but my point is, the stock engine is reliable at 265bhp (or less). Kevin made a good point though, with all this power, any modifications will have to be very well engineered. Home made components would most likely be the breaking point, not the engine. |

![]() GEEEEEEE You are getting old if that is the only rise out of you for saying you sounded like Paul Lamar...I would have thought the ground would have shook. BFG Few will believe this.... But, my blood pressure stays flat through all this RAH stuff UNTIL.... somebody says something truly funny. Yep. I can be caught rolling on the floor at 3, 4, or 5 AM. I also believe the Mazda would be a good choice but not for the inexperienced. The crux of the matter is there are few as gifted at Tracy Crooks. My whole point is that auto engines can be successfully adapted for aircraft use, not just the Mazda, IF you know what you are doing. Super humongous... "IF". And where is the financial responsibility coming from? Your personal assets ? No insurance company wants to write a low time pilot, with no time in type, playing test pilot with a one of a kind homebrew engine. They'd have to be as nuts as the builder/pilot/engine combo. I don't believe it will be significantly cheaper and that is proven by the cost of the many conversion engines on the market. Those that believe otherwise are delusional and should not even be allowed near a wrench, torch or hammer. However, this is where most of the boos and hisses come from. Yes, I'm speaking in generalities, but it is GENERALLY TRUE. It should also not be done by anyone that doesn't have the knowledge to do the maintenance on the engine, anytime and anywhere. Bob Reed FIRST... You have to get past the engineering obstacles before you can even think about a maintenance program. For my money, the R & D never ends and therefore.... passengers should not be put at risk in this kind of experimenting. This is an area of risk that insurance companies are loathe to write. If I'm wrong, show me where. Barnyard BOb -- Barnyard BOb -- |

There are others, they just don't post here. Do they fail? Of course, so do professionally installed certified engines. If you do the work yourself, if you are qualified to do so, you can have a zero time engine that puts out at least 180 horsepower for about $5,000 to $6,000. I have about $2400 in the engine at this point. I still have to buy the radiator and hoses and the ignition system. I also have to fabricate the exhaust system. My desire is to include a muffler in the system so as to keep noise levels down while in flight. Corky Scott |

If you stick with a "standard" aviation engine and prop, there is no guarantee they will be problem free, but at least the usual problem areas are well known and you should be able to watch out for them. If you go with a "non-standard" engine and/or prop you don't know what problems to look out for, so you can get bit, as happened in this case. In fact, if you just stop experimenting and do things the way everyone else has always done them (the "standard" way), you avoid lots of problems. Now excuse me - I'm going to lunch, so I need to sharpen my spear. Michael |

Thanks, Corky,
I had wondered what became of the Geschwender reduction drives after Mr. G's passing, and couldn't quite believe that a fully engineered and marketable product would have been bandoned. For some reason, a Google search with the argument fred + geschwender + psru gave Alternate Air Power, which now has a web site. It is well out of my price range for the moment; but is actually a real bargain when you consider the way it is built, and that it is made to swing a constant speed prop. I had also been unaware of the Belted Air Power name. It certainly looks like a reasonable solution for a fixed pitch prop, and more effecient answer than Steve Wittman's inverted engine solution--especially if you lust after a retractable nose wheel. :-) Peter Corky Scott wrote: On Mon, 06 Oct 2003 18:19:44 -0500, Barnyard BOb -- wrote: Geez, Bob.
