The supercharger on the stock motor made 250whp and the rebuilded motor the supercharger made 394whp.
I think HKS is going to have two versions of the supercharger. A street kit and a racing kit. If you look at version two they removed the A/C.
I used the Google translator
The Japanese forums said 250ps
