AMR500 instalation to a 4K toyota motor in my Locost clubman

As they say too much power is never enough so after watching a few vids of the Asin Supercharger form one of the little Kei cars from Japan I have bought one form a guy in South Australia along with two flanges and an 80mm V belt pulley which should make the Roots type blower spin and about twice engine speed This vid is Part one of the installation process. Now I'm not expecting too much but any improvement will be more than welcome. I plan to use the Weber carb that I recently fitted to the car and I will worry about the Jetting later Likewise Initially I am going to leave the distributor alone but the received wisdom seems to be that you do have to restrict how far the distributor can advance the ignition
