Since a supercharger is driven directly by the crankshaft, it requires no exhaust-side modifications like a turbocharger. This results in improved exhaust gas purification and better acceleration at low to mid RPM ranges.
Building on these traditional supercharger advantages, HKS developed the GT SUPERCHARGER, a next-generation system that overcomes previous drawbacks such as high-RPM inefficiency ("jam"), large size and weight, and mechanical noise. The result is a supercharger that delivers both environmental performance and high power output.
The HKS GT SUPERCHARGER, a lightweight and compact centrifugal supercharger, has now been redesigned as the GT2 SUPERCHARGER. This updated model offers enhanced durability and improved quality with upgraded components in the 7040 series.

THE DEVELOPMENT OF THE HKS GT SUPERCHARGER.
HKS has continued to expand its presence in the aftermarket across Japan, the USA, Europe, and Asia, primarily through high-performance turbocharger products. However, with exhaust emission regulations becoming increasingly strict worldwide—especially in the U.S.—it is becoming more challenging to meet these standards using turbochargers.
In contrast, superchargers, which do not interfere with catalytic converter activation, are gaining popularity—particularly in the U.S.—as they offer advantages in exhaust gas purification.
Typically, superchargers are of the positive displacement (volume) type, which can be difficult to install in the increasingly compact engine bays of modern vehicles. They also tend to present issues such as noise and vibration. HKS has addressed these challenges with the development of the centrifugal-type "GT Supercharger," which offers a more compact, quieter, and smoother alternative.
