Changing supercharger pulley size is one of the most effective ways to adjust boost levels and tune your forced induction system. A smaller pulley diameter increases supercharger speed and boost pressure, while a larger pulley reduces speed for lower boost applications. This 80mm pulley offers a balanced option for many performance applications. Always use genuine Kraftwerks or Rotrex pulleys to maintain optimal supercharger efficiency and preserve your warranty coverage.
