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.

4 Cylinder OHV Engine
A short video showing the new stainless collector/header that I made. I had wanted to do this for some time but didn't have much luck bending the tubing. I built a tubing bender and finally made the parts. It is silver soldered together. The sound has changed somewhat but the video doesn't do it justice. This movie clip is from the carburetor/distributor side of the engine. You can see the distributor advance when the throttle is opened.
