Right, it's CB Performance nowadays. It was a great series, built on John Karcey's specs, but HVW is driven by their advertisers.
And they never touched the aerodynamics of the test car.
Here's a discussion on theSamba.com on the Karcey specs, cam timing & etc. It discusses the Mankato 2-cylinder car, and includes this tidbit:

Another important modification for both fuel economy AND longevity is the use of aluminum cylinders (necessarily coated). The coating adds a little to the simple efficiency, and the extra heat shedding ability (this is the debatable part) may lose more heat energy from the cylinder, but also allows lower RPM without overheating. Charles Navarro claims a 7% reduction in BSFC (Brake Specific Fuel Consumption; lower is better) with his Nickies cylinders. The best part about these cylinders is how they work with the aluminum case and the aluminum heads: There is as much as a 14% difference in thermal expansion between the magnesium, cast iron, and aluminum alloys used in the main engine parts. Over time, these minor expansions and contractions fatigue the metals and you end up with cracked parts and bad sealing surfaces. All aluminum (think Porsche) makes for a much more durable engine.
