I never thought I'd find it but I figured VW MUST have researched and prototyped a pushrod flat 6 sometime in their history. I've been googling on this subject for sometime, but never quite hit the right combination of keys until this morning (literally after a dream last night). For those of you who know all about this engine, please excuse this if it's redundant, but it's just too tempting to look at this engine as a potential VW swap.. afterall.. it's "Factory".
VW was developing the WasserBoxer 4 cylinder, and had a 6 cylinder variant also in the works. Market Research suggested that it was not worth the tooling/ development for the 6 cylinder, so VW sold the design to Oettinger. The Vanagon experts can chime in but as I understand it, Oettinger built a "Tuner" synchro Vanagon, and offered two versions of the six.

to get the connection to the teener:
back in 2006 I visited the Salzburg Oldtimer Fair and there was a ravenna green teener, that was a "experimental car" from Oettinger guess what - it had an old watercooled flat six in it the guy told me that the car was the 1st and only prototype car that had this engine in it - and he had all the paperwork and constructive information with the car I can't remember all the details he told me, but I found two old photos: Attached image(s) |

Thanks for posting, that car has a paint job and wheels I'm envious of (IMG:style_emoticons/default/hissyfit.gif) I'm guessing that the 3.7Liter 180HP flat six must have had a somewhat agricultural torque curve. The average torque output almost always calculates out to 1 foot-lb per cubic inch on any engine built in the 1950's and onward, so I'm going to guess that at 222 cubic inches (3.7 liters ~ 222ci), there was 200 ft-lbs at hand. Isn't this somewhere near the limit of 1st gear in the 901 transaxle? |
