I came across these a couple years ago, there are several copies of the videos on youtube. I do beleive these are spark ignition motors, not compression at least the V8s. The second video/ first V8 is simply a scaled down Chevy V8 for the most part. The last video is a blown alcohol motor just as you would find on a top fuel drag car, dual magneto spark ingition and all. My friends and I had thought how cool it would be to make a RC car or go cart with one until we really started looking into them. Found the website for the guy that makes them. They are pretty much a novelty item and thats about all they're worth. First is the price tag, the standard v8 started at about $5k and the blown alcohol was considerablly more. Second was the HP ratings, the standard V8 was only about 5HP. For $5k I could buy a GM crate motor and stick it in a Chevette and have a car running around a 12sec 1/4 mile. Or put a 4cyl car motor on a go cart! All in all they are really cool but thats about all they are
