Sure, the rotary engine may be an oil-eating machine filled with Nazi-designed spinning tortilla chips that turn money into nightmares, but god, I love them. My first car was an RX-7, and while, somewhat tellingly, I haven’t owned another rotary since, I think about them often. Not as often as Rotary Stifler, aka Rob Dahm, though, and especially not since someone gave him a homemade 12-rotor marine engine to try to get running.
Yes, 12 rotors. It’s a lot to contend with, even for a rotary expert like Rob. This engine was cooked up and built by a guy, which means it has all kinds of idiosyncrasies and quirks that have to be dealt with to get this pile of parts that hasn’t run since 2008 back into fighting shape. Maybe it’s just my natural love of schadenfreude, but seeing an hour-and-a-half-long video of people organizing springs and seals and figuring out rotor timing on this one-of-a-kind motor with very little documentation is so satisfying, which is why I’m sharing it with you.
