Installing a centrifugal supercharger system is the hard part; with that done, it's really a simple proposition to bolt on a smaller pulley, thereby spinning the compressor faster, making more boost, and producing more power. Remember, any given pulley will produce different results on different engines. In our case, a 3.12-inch pulley created 10 pounds of boost so we didn't run the even smaller 2.95-incher shown. The only way to know for sure is to measure the results with a boost gauge. Thinking about adding some boost? Vortech can create a performance estimate for your combo and recommend a pulley.
