Show original supplier description

The Rotrex C38-91 KIT is a centrifugal supercharger system engineered to enhance the performance of four-stroke gasoline engines. This comprehensive kit provides the core components for forced induction, including the Rotrex C38-91 supercharger unit, an oil canister, an oil filter, necessary hoses, and lubricating oil. While this kit provides the main supercharging components, it is important to note that a compatible pulley and an oil cooler are essential for proper operation and must be acquired separately. The C38 supercharger series is designed to support engines with a supercharged output capacity of up to 530kW (approximately 720hp). The technical data sheet indicates that the C38-91 is capable of supporting a wide range of horsepower outputs, from 354hp up to 720hp, and is well-suited for engines ranging from 3.0 to 6.0 liters in displacement. Installation of this supercharger kit requires specific components like pulleys, which are available in various diameters (e.g., 70mm to 110mm) and can be mounted or unmounted. An oil cooler is also highly recommended, with options for 10, 13, or 16 rows. Buyers can consult Rotrex Calculators to ensure they select the most appropriate model for their specific engine and performance goals.
