Mmm, interesting. .. I was thinking a bout turboing a 125cc scooter, but finding a suitably small turbo is a mission. Where did you get the turbo from?
90%of my rides are/were turboed, its the only way to make good power, muhuhahaha
Just watch out for the carb pissing out fuel when under boost, it should ideally be sealed in a box with the same boost pressure in the box...
The easier way is to put the turbo between the reeds and carb.
What type of fuel pump are you running for the fuel supply? It should be a EFI pump, and you should also be using a boost reference regulator/rising rate regulator.
I personally would rather go nitrous, for simplicity, but would love to see a well designed turbo on a blaster.
