Maybe now it’s not that impossible anymore because someone did it ,and someone built a radial engine from old VW parts.

Furthermore this engine is fully functional but the man who built this isn’t sure about the power this engine is capable to produce ! The genius behind this homemade masterpiece is Arnold de Man (an appropriate name as he obviously is the man).

He used parts from an air-cooled flat-four VW engine to create this 7 cylinder radial and just to inform you it’s displacement is 2068cc and also it weights 80kgs!
Furthermore we suggest to watch the video, also feel free to share with us your opinion
