KAVS Motorsport are proud to finally deliver their world-favourite supercharger pulleys for the Lotus tuning market.

Our pulleys are CNC machined from high-grade aluminium; which receive hard, anodised coatings. This helps to protect the pulley for a long-lasting product, whilst helping to keep it as light as possible. Strict quality checks are carried out through the duration of the manufacturing process to ensure each of our products are made to our usual high standard.

By reducing the size of your supercharger pulley, you make the supercharger rotors spin faster; therefore increasing airflow through the intake at a higher boost pressure, and yielding higher horsepower and torque.

Typical gains from the 77mm pulley upgrade are 8bhp and 10Nm of torque across the entire power range. We also reduce the weight of the supercharger pulley from the standard 497g down to an exceedingly light 173g; reducing the rotational mass and reducing stress on the drivetrain.

For Lotus, we offer a range of pulley sizes for different levels of performance. For the stock Lotus Exige S, we recommend the 77mm. After many hours of testing, we decided that it was the best size for the perfect balance of performance, inlet temperatures and reliability.

Those concerned about the health and reliability of the engine post-modification need not worry, as KAVS Motorsport’s in-house engineers have used a variety of methods; from accelerated life testing within our facilities, to hundreds of hours testing on the track with our own vehicles (not to mention the thousands of hours of driving our happy customers worldwide have experienced!), to ensure that our products will not fail on the road or track.
