Natural aspiration is a beautiful thing to some. How to extract as much usable horsepower from your engine without the aid of supercharging, blow dryers, or laughing gas appeals to more than a few enthusiasts. Once serious travel begins along the all-motor route, many decisions have to be made, such as what cams to use, compression/ratio, ECU tuning, and any other variable you can imagine. When it comes to finding a solution for intake, it seems only three ideas are considered: a standard underhood intake, a cold air system, and a factory airbox or similar variation. Individual throttle bodies are often overlooked. What’s so good about this? For one, you are allowing each combustion chamber to have its own source of incoming air. The runners on the intake manifold are also shorter and more direct. However, ITBs are not CARB-approved, and depending on your setup, are not likely to be very street-able. The reason? The amount of air stuffed into the combustion chamber is great for high-rpm racing, but street driving in low rpm causes great suffering and increases gas consumption by a significant amount. Let’s take a look as Elton at Raceline Development installs the Blitz unit on a B16A motor.
