Now, we know there'll be some people who'll say, "Sure it works as a demonstration motor, but will it work in a car?" Well folks, Mr. Blaser is way ahead of you, he's installed his NAHBE components in a well-used military jeep with excellent results, including a noticeable increase in performance and mileage!

After the NAHBE demonstration was over and we had packed the engine away, Bill popped open the hood of his Ford four-wheel-drive pickup and showed us his own solution to the fuel shortage and pollution problems. He had equipped the truck's gas-thirsty 390-cubic-inch V-8 with a reservoir tank that metered pure alcohol through an inlet tube and into the carburetor venturi whenever the accelerator was depressed (the rate of flow was controlled by a vacuum switch connected to a vacuum line on the carburetor, hence, as carburetor vacuum increased, more alcohol was fed to the carburetor air inlet). Bill also kept his fuel tank filled with a 10% alcohol-to-gas mixture, between both systems, Bill figured he was running on a 15% alcohol blend. What he knows for sure, though, is that his mileage increased from 8 to 12 miles per gallon, a 50% gain no matter how it's figured! And, a little poking around inside his truck's exhaust pipe revealed something just as interesting: There was hardly any trace of carbon or any other filth on its inner walls, which gave us a "seat of the pants" impression that gasohol is one clean solution.
Even better, though, is what Krass told us just before this issue went to press: A local mechanic has offered to convert Bill's truck to NAHBE specs just for the price of the parts, which shouldn't make too much of a dent in his wallet (in fact, the money he'll save on fuel should make up the difference right quick) and ought to give him the cleanest exhaust in town!
