There were no O2 sensors present to give feedback, Augie just listened to the engine and tuned by feel. He demonstrated his manual air/fuel ratio control method on the freeway, and indeed you could tell the engine was running leaner by the way it sounded and drove. Augie says in traffic the Nova gets 4 miles per gallon and on the freeway, if he tugs on the fuel cutoff switch a little, it will get 10 mpg. There was no smoke, and we weren't choking on fumes from an overly rich part-throttle condition, either. Think about it like water flowing through a channel (although air is compressible). With an L79 327, a Muncie four-speed, and cheater slicks, the car. You want the air entering at a controlled and more predictable rate for better tuning also. The Nova is an ex-drag car that was built by Don Hicks Race Cars of Buena Park, California, in 1966 for Sonny Young. To get an idea of its cruising manners, we short-shifted First and Second and rumbled down the road in Third gear at part-throttle. One of the reasons for the velocity stacks is to speed up & smooth out (closer to laminar flow) the air entering the cylinders. We stabbed the throttle a few times and the small-block barked to life with the snappy throttle response we've come to expect from mechanical injection. With a quick turn of the key, the engine cranked and then settled into a loping idle that didn't sound like the smooth, boring exhaust note of other injected engines we've been around. Its been proved time and again, the straighter the flow the better, but this can be somewhat misleading, since you need some turbulance to help mix the air fuel mixture in a natrual asperated application, especially when Nitrous Oxide comes into the picture.
