Supercharged home made Straight Eight by Desperate Dan Vid 2
Built in a shed, it fired up first go. I was hoping it would sound real lumpy like a drag engine, but it runs too smooth, and it's too quiet even with unsilenced 9" pipes! The timing was a pain to sort out the Rover distributor runs backwards, I had to take the heads off to work out the firing order!!! See the shed it was built in on Vid 1. Added May 2012: OK, my nails are dirty, maybe because I'm an engineer & build stuff? Maybe your nails are clean because you can't build eff-all & just sit behind your computer? C'mon folk, get a life.

Scale Running Model Harley Panhead Engine by Ron Colonna
V-Twin Panhead Ignition: Spark Bore: 1 5/16 in. Stroke: 1 1/2 in. Two Cylinder Four Cycle No Castings Used This engine was scratch built to a scale of 2/5ths or 40% of full size. The bottom end was taken from a drawing of a Knuckelhead engine that I puchased on e-bay. The top end was patterned after photos taken from e-bay of Harley parts for sale. I also bought a Harley repair manual that helped with the oil system. The crankcase was split into three sections instead of the usual two for ease of machining. The ignition is solid state and I use a GM coil which fires the two plugs simultaneously. Timing is advanced and retarded with the timer body. Two rotating magnets fire a Hall effect device at the proper times as per full sized points. The engine is large enough to produce that lovely V-twin sound.
