So, you think you build a great “model” do you? How about a functioning, supercharged V-8 engine? This half hour segment shows the Conley factory, and I have other scale model engine links from the same guy and others. Of course each engine is worth more than a real one, and only develop about 5 or 6 hp each, but still cool to watch.

They really sound like bigger engines than they are, and I love the cam loping some of them display.
