04/04/2002 09:36:37 AMHi Gary: GPU stands for "Ground Power Unit". I have heard of people usingthese for expermentals I believe tha crank need to be changed out forthis. Good Luck!"Gary McNeel, Jr." (at)matronics.com on 04/03/200211:27:44 PMPlease respond to pietenpol-list(at)matronics.comSent by: owner-pietenpol-list-server(at)matronics.comcc:Subject: Pietenpol-List: Semi-UrgentWhat is a GPU military engine? Made by Continental. Still in GPU housing.Trying to get more information on model and serial #s.First, none of you can out bid me if it is a good deal. That said, here isthe eBay link for it:http://cgi.ebay.com/ebaymotors/ws/eBayI ... r=0&t=0Any of you officiando's know what this is and can it be converted foraircraft use. I am leaning toward the O-200 after some urging by a friend Irespect greatly for his aircraft knowledge, though I still think about theCorvair. Decisions, decisions.TIARegards,Gary P.

Gary,There was some conversation regarding the Ground Power Units sold atmilitary auctions within the last year. They are essentially electricgenerators and from what I remember, the motor is slightly different from atrue C-85/O-200, although I'm not real sure. I can't remember what theconsensus from the group was. Check the archives. Also, there arecompanies that specialize in military auctions and you can almost alwaysfind one of these from them.http://www.galleria-e.com/cgi-bin/colem ... og/1097The item for sale is listed in Mesa, maybe DJ could check it out for you.(Sorry DJ for volunteering you)Robert "the Yankee" (with a wink toward the bijou) HainesDu Quoin, Illinois

Forgot to add one thing. They are rated in kW output which I would guess isan electrical output. Knowing that to provide a certain amount of outputfrom a generator, you must provide more input to cover the inefficiencies.So if the unit is 15kW which converts to 20 HP, the motor may be at least30-40HP. I know... bla bla bla.What I'm trying to say is that there's an easy way to quickly judge whetherthe GPU is even worth taking a look at; ignore anything in the 1-10kW range,it's probably just a Briggs and Stratton. :)But if its one of the larger ones, have them provide a motor displacement ormotor serial number.Robert Haines________________________________________________________________________________Date: Thu, 04 Apr 2002 09:02:27 -0600
