to me turbo charging is way easier then super charging, and i've got some good experience in the area. Supercharging your talking about putting a hole in the side of the motor, figiuring out how to adapt a pulley onto the crankshaft, getting that pulley out, might need a bearing to support it and then a seal, and then figuring out how to mount the charger. would be cool to hear that whine but thats out of my realm of expertise. I could twin turbo it, or bi-turbo. I already have some take off turbos from my car, stock twin turbo so each turbo is oriented for one side or the other. It would be totally sweet and really get that wow factor, but i just think this little 1.3L motor wouldn't spool them both up anywhere useable. maybe for a drag bike lol. Id like to get this bike to around 200 hp, and one turbo will be plenty for that
