So you’ve probably seen that video of a guy who built the miniature V12 engine by hand (if not, it’s here: http://www.youtube.com/watch?v=CJd-WY0mm88). Here’s some more interesting model engines:
Never mind that one, I want to know more about this miniature flat 12 Ferrari 512 Testarossa engine:
The website referenced in the YouTube video is motorconcept.ch, but that site isn’t currently online, and it looks like it hasn’t been since 2010. However, through the magic of the Wayback Machine we can see a bit of the content on the site when it was captured in 2010 here. And through some more magic courtesy of Google Translate, I can see that the engine was built by Daniel Aquilon, who I believe is the builder of the first V12 mentioned. The website seems to say that the engine is a 12 cyl.
