On every two stroke forum you will find a topic about turbocharging moped engines. Everyone will tell you it doesn`t work, altough there are some vids on youtube of turbocharged two strokes.
I love it when someone tries something different to prove everyone wrong. I found this Puch maxi on mopedarmy.com and couldn`t resist to post it.
The performance according to the owner:
Runs and is very loud. Still need to build a cover for the oil pump and
housing for the battery. Builds about 4 PSI of boost with current
wastegate spring. Very narrow power range, fun, and not practical :D
I'll post some video/update later.
