Is the ARDUN engine better with or without the supercharger?

In the long run Steve thinks this engine is probably a better street rod engine with a single four barrel and no supercharger, because at 10 to 1 it runs excellent on pump gas with plenty of power. But the look of a supercharger is hard to beat. With the four barrel it made 306 horsepower at 5,700 RPM on gas in the previous test.
