CyberSushi Posted January 16, 2006 Share Posted January 16, 2006 Hi, Looking at all the various engine options out there is starting to make my head spin. While an automotive diesel engine is the most appealing, I'd rather be first to follow than on the "bleeding edge" What I'm looking for is the dry weights of various engines. Can anyone help out with the following weights? Lycoming O-360 (or equivalent) Lycoming O-540 Mazda 13b Rotary BMW 330d Volvo D5 Subaru WRX 2.5 Toyota Avensis 2.2l D-4D engine Thanks Soosh Quote Link to comment Share on other sites More sharing options...
gontek Posted February 24, 2008 Share Posted February 24, 2008 In trying to research a lot of the newer auto engines, I found that manufacturer info hardly ever list weight, in fact specs are far from standard. It's just not that important to auto people like it is to us aero people. I found a few engine weight lists out there though. You would have to look to the references to find details on exactly what was weighted - as in dry, wet, installed, etc, but these lists give some useful baseline information that can be found on the web. 1. http://www.bacomatic.org/~dw/library/txt/engfyi.htm 2. http://www.team.net/sol/tech/engine.html 3. http://www.gomog.com/allmorgan/engineweights.html Since I am using your post topic here are some answers from the lists: Lycoming O-360 (or equivalent) Lycoming O-540 - 515 lb (1,3) Mazda 13b Rotary - 260 lb (1,3) BMW 330d Volvo D5 Subaru WRX 2.5 Toyota Avensis 2.2l D-4D engine that gives you two answers anyway. It looks like new data is hard to some by, the most current reference I saw is from 2004. Time to hit the public library. refs 1 and 3 appear to be duplicates of each other, with ref 1 parsed a little better. Quote Link to comment Share on other sites More sharing options...
Edge 513 Posted February 24, 2008 Share Posted February 24, 2008 I don't know what iteration of the 540 you 'found', but a narrow deck- parallel head 540 does NOT weigh 500+ pounds...and Kieth Spreuer[sp] says his Subaru weighs over 450...and a finished rotary will not be 260. Keep searching, you're digging up turds not potatoes. Quote Self confessed Wingnut. Now think about it...wouldn't you rather LIVE your life, rather than watch someone else's, on Reality T.V.? Get up off that couch!!! =) Progress; Fuselage on all three, with outside and inside nearly complete. 8 inch extended nose. FHC done. Canard finished. ERacer wings done with blended winglets. IO540 starting rebuild. Mounting Spar. Starting strake ribs. Link to comment Share on other sites More sharing options...
gontek Posted February 24, 2008 Share Posted February 24, 2008 Here's the results of another search. It's not too hard to google an engine and the word weight. http://www.aviator.cc/aircraft_engine_weights.html Then again, the internet is not the most reliable source of data. The public library would be better. Quote Link to comment Share on other sites More sharing options...

I'm not just pulling these data out of my ass though. Quote Link to comment Share on other sites More sharing options...
Edge 513 Posted February 25, 2008 Share Posted February 25, 2008 When you give someone a definative reply. They may rely on that reply without further investigation. If I was looking at your past helpful response- I might offhandedly place more or less interest in an particular engine choice. I am just saying that your two sources are not useful, as at least in the case of the 540, there are at least 40 different 540 configurations revolving around a basic parallel or angle head 540 assembly. The angle head is much heavier and is not suitable for a Cozy installation. It goes on from there. If Chris, Nick or I had put[in his flying 540RG] or were putting 515# engines in MarkIV's we would be fools. And whilst your looking for tasty potatoes, good luck out in the garden of the internet...its an information jungle out there. Quote Self confessed Wingnut.

gontek Posted February 25, 2008 Share Posted February 25, 2008 Good point. You would be fools to make your propulsion decisions based solely on information from forum posts about weight estimates. Unless possibly there was plenty of discussion dissecting the nature of the information along with some Dr. Phil type metaphors about gardens of potatoes and turds, in which case at least it would be entertaining. A good source of data for different aircraft engines is in the back of Jane's All the Worlds Aircraft. Check your local library to see if they have current copies. I do not know of any good single source for automotive engine data. The links posted are the only ones I have seen, and the references listed are mostly magazines like "Car and Driver" or "Popular Science". Even then the info will be different due to modifications required for aircraft use. I don't even think SAE has anything like this. Quote Link to comment Share on other sites More sharing options...

Terry Posted February 25, 2008 Share Posted February 25, 2008 Here are some weights that I believe are accurate. The Lyc 540's that weigh 500+ # are angle valve and turbocharged and include the weight of the turbo and exhaust system to the turbo. TCM Weight Range Horsepower O200 190 100 O300 268 145 IO360 290 – 300 180 – 210 O470 378 – 410 235 – 240 O470H 495 240 IO470 426 – 432 250 – 260 IO520 417 – 431 285 IO520NB 478 285 IO520P 400 250 IO550 421 – 450 300 LYC O235 243 – 255 100 – 125 O290 230 – 251 125 – 135 O320 243 – 283 140 – 160 IO320 250 – 276 150 – 160 O360 254 – 301 168 – 180 IO360 261 – 277 180 Parallel Valve IO360 288 – 324 200 Angle Valve O540 356 – 375 235 – 260 IO540 373 – 389 235 – 260 Parallel Valve IO540 414 – 444 290 – 300 Angle Valve Quote Link to comment Share on other sites More sharing options...
ezelady Posted June 3, 2008 Share Posted June 3, 2008 A great place to look for engine weights for the certified stuff is on the FAA website. Its under type certificates. These weights will be "dry" and without all the goodies that make them actually run. Have fun. Quote Link to comment Share on other sites More sharing options...
