So.
I recently took possession of two(2)2.7L(164") Corvair engines. (IMG:http://www.914world.com/bbs2/style_emoticons/default/biggrin.gif)(IMG:http://www.914world.com/bbs2/style_emoticons/default/biggrin.gif) I doubt it would be as simple as merely welding sawn,machined cases together, (IMG:http://www.914world.com/bbs2/style_emoticons/default/smlove2.gif) then,installing a custom crank and cam.The problem then becomes the cylinder heads. Metal joining technology has come a long way since '65. Look,if that guy out there in boonville Norway(er..corr Sweden) can do it,what,if only money,is stopping us(me)? It is a matter of will.Luke,do or not do. (IMG:http://www.914world.com/bbs2/style_emoticons/default/welder.gif) / (edit:08/14/16): -------------------------------------------OOOOOOOOOOOOOOOOOOOOOOOOO----------------------------------------------------- http://www.alfabb.com/bb/forums/boxer-engi...-8-project.html Hmmm..Seems the flat eight affliction is not confined to Porsche enthusiasts,it's catching. (IMG:style_emoticons/default/laugh.gif) / (Edit:08/17/16): The context,an answer to a question posed to 'engine dorks' about crankenrods. HD You could use a knife and fork rod set,the pistons in line,radially. The advantage of the 'boxer' design is the cancelling of the primary unbalance forces. Pointers: https://www.google.ca/webhp?sourceid=chrome...a%20boxer%20six https://www.google.ca/webhp?sourceid=chrome...boxer+animation https://www.google.ca/webhp?sourceid=chrome...nd%20g%20forces The crankshaft is connected to the wristpin by the,'connecting rod',holding the piston,with the piston,or 'wrist' pin. https://www.youtube.com/watch?v=l-KSsaH-3b0 (IMG:style_emoticons/default/smile.gif) Dorks,and Boffins,working at Porsche,MercedesBenz,Ferrari,and other manufacturers,for centuries. You can join them here,bring a slide rule. https://www.google.ca/webhp?sourceid=chrome...+degree+florida 11,768 m/s² 1200Gs - Deceleration of a woodpecker's head! (IMG:style_emoticons/default/blink.gif) / 'Boxer': Pistons move in opposite directions,a crankpin for each piston. https://www.youtube.com/watch?v=j_g_K0nyGHQ 180* 'Flat' 12: Pistons move in same direction,sharing the same crankpin,like the V-12. https://youtu.be/j_g_K0nyGHQ?t=23 https://www.youtube.com/watch?v=j3CkVwtOPX4 The 911 motor is a 'Boxer',the 917's motor (912) is not. Because the length of the crank is greater with the boxer configuration. https://www.youtube.com/watch?v=m3KdpzL3Hkk https://www.youtube.com/watch?v=_o8E4WCC4F8 (IMG:style_emoticons/default/drooley.gif) Need to know: http://www.pattakon.com/ http://www.pattakon.com/pattakonEduc.htm http://bestplay.pk/watch/V6PGO03K6cI Like the Merlin V12 engine above,the 180* flat engine has 6 crankpins,just like the Boxer Six. The crank is offset 3" to grind the 6" stroke crank,27L. / https://www.youtube.com/watch?v=xbZ9RD6BTMw http://www.e31.net/engines_e.html Technology Terminology,for to make communicate.Some,obviously,are not on the same page. Needing a part,called a part store,"Do you sell 'whatchyamacallits',for my motor thingy?". (IMG:style_emoticons/default/laugh.gif) (IMG:style_emoticons/default/lol-2.gif) The reason for the forked 'Connecting Rod',is performance,the reduction of engine weight. The HD,and the RR,have their cylinders opposite each other,in the same plane.The greater complexity of manufacture was a calculated compromise. The weight of the crankshaft was reduced,as the secondary unbalance forces were nulled by the inline cylinders,less vibration. The shared crankpin of the 917 engine's side by side,'conrods',are the result,also,of a compromise in the cost of manufacture,and simplicity The proposal for such forked rods,in the initial design stages of the 917 engine,was rejected,as their mass was unsuitable for the high rpm engine. Two different applications,two different results,both of which excelled in their field. https://www.google.ca/webhp?sourceid=chrome...iston%20engines https://www.google.ca/webhp?sourceid=chrome...connecting+rods http://www.practicalmachinist.com/vb/antiq...-merlin-306661/ http://www.craftsmanshipmuseum.com/Tomlinson.htm http://www.speedwaymotors.com/Scat-932911-...troke,3181.html https://rideapart.com/articles/birth-harley...on-v-twin-motor RR Merlin crank.Forged,hollow,tubular and light.Sheffield. http://bbs.homeshopmachinist.net/threads/4...ine-Restoration http://www.practicalmachinist.com/vb/gener...ankshaft-73615/ The finish anvil below,one of _. Looking to make a piston engine? (IMG:style_emoticons/default/idea.gif) (IMG:style_emoticons/default/evilgrin.gif) So,yeah,a flat 180-12 engine can have the cylinders inline,the boxer's must be offset.The offset distance is the thickness of the web,rod and journal,if any. A method to circumvent the offset,with minimal complexity.: / Boxer Cranks MercedesBenz auto V12 Bmw auto V12 Diamler Benz DB 605 V12 Crank 912 Shafts https://www.google.ca/webhp?sourceid=chrome...+917+engine+fan Twin Supra V12 crank,heavy man.
